New Board President: Integrate Improvised Approaches to Certification

By Denis Poirier Jr., CFPHS, CFPAI, AJPP, AJPPCC, CFPIM, CFPCC, IFPS Board President and Chairperson

»

TO SAY LAST YEAR was more challenging than other years would be an understatement. For me, any mention of 2021 immediately pulls thoughts of how life was forever changed and remains so moving forward.

With all the struggles and challenges, is it possible that anything good could come from such a challenging year? I would say yes; despite all the negative, I still saw great things.

When people couldn’t travel, they got creative. The establishment of the home office was priority one for just about everybody. An unintended consequence of the home-office boom was society’s willingness to try new technologies. This created an environment rich in innovation as everyone raced to solve problems that had never existed before. People flexed and made it happen. Put simply, society embraced change.

As I consider the International Fluid Power Society, 2021 was all about thinking outside the box. For example, historically the accredited instructor workshop was a process normally completed with attending in-person training sessions. But 2021 brought about a willingness to try new training delivery methods. As a result, the virtual accredited instructor workshop was born.

Surprisingly, what we found was that not only did a virtual session work, it worked well!

Other examples include livestreamed training sessions on challenging topics in support of certification. Attendance for these training sessions was solid, and the feedback was positive. Adding video content to social media and other public sites allows others to rapidly locate and view fluid power-related content. Adding additional animation into other electronic study manuals enhances learning for those who choose a self-paced study option.

The momentum gained over the past 12-18 months should not be wasted.

Necessity has created a climate of change. The availability of personal computers provides the interface to endless opportunities. Advancements in communications, software, and hardware bring with them a new frontier of learning experiences in which two-way streaming sessions between continents are now normal. Virtual reality provides an ever-expansive environment in which gaming tools can be leveraged to support the delivery of technical training. Why would we go back to the way it was? Why wouldn’t we look for a balance between then and now?

As I look to the year ahead – whether it is accessing prerecorded sessions in the IFPS membership database, expanding media content in the electronic study guides, attending an IFPS virtual training session, or incorporating virtual reality into future IFPS products – we have come too far as a society to disregard the benefits of integrating technology into our learning strategy.

Employing multiple delivery methods to support certification provides a sound solution. As IFPS members we should consider what an integrated world should look like and how incorporating technology can support the expansion of certifications to other parts of the globe. It is an exciting time, and I hope you are as excited as I am for the journey ahead.

Emergency System Fails to Close Safety Doors

By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training

»

A LOCAL REPAIR shop was asked to troubleshoot a problem on the hydraulic system that closes a watertight door on a floating casino.

The circuit was designed with an electrically driven hydraulic power unit that would open and close the door with two hydraulic cylinders. If there was a power failure, the normally open door would be closed with a manual hydraulic valve connected to an accumulator.

A problem was encountered when the door was tested during a safety inspection. They found that the accumulator circuit that was designed to open and close the door two complete cycles out and back only moved the door in one position about halfway and would fail to move any further.

If they put power to the hydraulic unit, it would cycle the door as needed. Shutting it down and trying the manually operated piston accumulator cycle would only move the cylinder halfway before it stopped. They observed the nitrogen gas charge would show system pressure when the main electric unit was running and dropped to a very low pressure when the manual circuit was engaged.

What could be the problem?

Solution to the November/December 2021 problem:

Drifting Cylinder in a Rolling Mill

When I looked at the problem, I asked the company for the circuit and noticed that the directional valve center position had the A and B ports blocked, preventing the signal lines from quickly draining to tank, which would allow the checks to totally close and lock the cylinder into position. Typically, A and B pilot-operated checks require a valve center position to have A and B connected to the tank. I think the designers experienced the same drifting problem and thought blocking the A and B ports was the solution.

I had the customer change the relief valve to a solenoid operated on/off pilot-operated relief, which lowered the back pressure caused by the retrun filter. They also changed the center position of the directional valve to an all-portsconnected design.

By Carl Richter, Vice President

ustainable manufacturing is being promoted globally. Some companies feel it is important regardless of the costs, others do what makes sense, and still others are on the sidelines and unsure of the available options.

The U.S. Environmental Protection Agency defines sustainable manufacturing as “the creation of manufactured products through economically sound processes that minimize negative environmental impacts while conserving energy and natural resources. Sustainable manufacturing also enhances employee, community, and product safety.”

Regarding hydraulics, we can focus on three basic principles: social, environmental, and economic. The sustainability message helps a company focus on the long term, increasing efficiency, eliminating waste, and providing a safer environment for employees while strengthening the company’s brand, With existing hydraulic systems operating throughout the world there is always room for improvements regarding sustainable manufacturing.

At the end of the day, for most companies it is about production, how many parts per shift and per day, and so forth. Changing machines is costly and may not make sense in the short term. Many companies are reviewing alternative options for new builds or upgrades and how to make them more sustainable.

For hydraulics, options available today include electromechanical actuators (EMAs). Some companies have tried EMAs with limited success.

Many EMAs are not up to the hydraulic robustness or are not cost effective. Other options include techniques to make the hydraulic power unit more efficient, such as installing a timer to turn off the HPU motor when not operating for so many minutes. Or using a variable-frequency drive to control a pump motor or implement servo-controlled HPUs. The servo power unit is becoming popular; it minimizes or eliminates hoses and hydraulic connections and provides power on demand while offering more control capabilities.

What if there was a technology that combines the best features of hydraulics and the electromechanical technologies? And what if that technology also reduces the challenges? The Kyntronics smart hydraulic actuator (SHA) is an ideal solution for sustainable manufacturing.

SHA technology contributes to sustainability momentum in five key factors that support the basic principles: environmental, reducing waste and pollution, reducing energy usage, saving time and money, and the human factor.

Environmental. The SHA is a self-contained hydraulic actuator that discharges no contamination, doesn’t leak, and uses a minimal amount of fluid. Even with a catastrophic towmotor incident, a mop can clean up most spills.

Reducing waste and pollution. SHA fluid does not need to be replenished on a regular basis.

Reducing energy usage. The SHA is a poweron-demand device that only uses power when it is needed and is therefore an efficient actuation solution. Compared to a typical continuously running 15-horsepower HPU, an SHA can save around $8,000 per year in energy costs.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Saving time and money. With the SHA, the hydraulic infrastructure design time is eliminated, as are maintenance challenges.

The SHA is simple to install. Bolt it up, connect the wires, setup the parameters, connect the fieldbus as needed, and it is ready to perform.

The human factor. The human factor is an important but forgotten part of sustainability.

As mentioned, the SHA eliminates dangerous slippery surfaces. There is no worker contamination from continuous cleaning.

The SHA is a significantly quieter solution, and

noise is substantially reduced by the power-ondemand. With the lower-decibel servo solution, the factory is a much safer, quieter environment.

The SHA is a versatile solution that combines benefits from established successful technologies while solving sustainability challenges. It meets current needs and will help future generations to meet theirs. The SHA is one small tool in a toolbox that can make a change.

afety and productivity are top priorities for any machine builder, especially where human interaction with the machine is common.

Time and again, industrial radio remote controls have proven central to the rapid improvement of productive, efficient, and safe machine control solutions. Offering the inherent advantages of untethered operation, coupled with rapid advancements to radio communications and intelligent functionality, it is no wonder that the inclusion and integration of radio controls into hydraulic and pneumatic machinery continue to grow year after year.

Hydraulic and pneumatic equipment is found in a variety of environments and industries, each with its own set of challenges for keeping operators and machines safe. Radio remote controls allow operators to position themselves with an optimal view of the machine, the work being 8

done, and the broader operating environment. They remove the potential of the operator working in hazardous or dangerous environments and locations. In addition, they enable the direct communication between the equipment operator and jobsite operation personnel, while reducing miscommunication and the potential for the misinterpretation of hand signals. They also remove assumptions of the machine operation in relation to the environment. By means of a radio remote control, the operator can evaluate work tasks, check conditions, and constantly monitor the work environment for operational changes, obstacles, or sudden weather events.

State-of-the-art products provide complete machine feedback to the radio remote control for the operator. Feedback options include high resolution displays, LEDs, haptic, and audible alerts. Safety initiatives WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

that are driving all industries have increased the demand for the use of radio remote controls. More recent developments such as RFID operator cards and data logging devices can manage operator access and monitor machine and control activities. Another safety initiative for radio remote controls is the use of live video feedback technology. This innovation allows for the display of live video images of the working environment on a color display that is integrated into the radio control transmitter. The video feature may work with one or more cameras installed on the machine or in the working area and is easily selected via a rotary or toggle switch. Using a separate radio link with a range of up to approximately 150 meters (165 yards), the cameras transmit high-quality live images to the radio control’s display. Operators benefit from a clear view of the working area. They can detect and react to potential dangers, and work becomes considerably safer. Additionally, the operator can choose between the live video feedback or machine diagnostics.

(Continued from page 9) Remote operation of fluid power equipment All hydraulic and pneumatic equipment lends itself to remote operation. Radio remote controls can be found in a broad range of industries including mining, manufacturing, oil and gas, entertainment, utilities, construction, agriculture, transportation, automation, and logistics.

Radio remote controls frequently control construction equipment such as excavators, dozers, mobile truck cranes, wheel loaders, self-erecting cranes, and all- and rough-terrain cranes. They also control oilfield tools such as pipe handlers, rig walkers, torquing tools, and winches.

Additionally, they can be seen controlling industrial transporters, trailers, dollies, lift trucks, and specialty agricultural equipment. As long as the equipment is electrically or electrohydraulically controlled, radio remote control systems can be easily implemented via several standard interfaces. These may include relays, variable voltage/current/PWM, relay or high-side switch outputs, or bus interfaces such as CANopen, CANopen Safety, Profibus, RS232/485, Profinet, SAE J1939, UART, IQAN, DeviceNet, and EtherNet/IP. The broad capability of today’s radio remote controls typically offers the same control the driver would have in the cab or at the control station.

The operator sees machine feedback via display screen graphics, LEDs, audible or haptic feedback, or live video feedback from remote cameras.

These capabilities significantly increase productivity by minimizing extra personnel while speeding up work processes and making each task safer.

Radio remote controls offer the operator an optimal vantage point of the controlled machine, reducing miscommunication between workers and permitting constant monitoring of the operating environment.

10

JANUARY 2022

Assessing remote control systems Safety is the top priority when discussing radio remote controls. Concerns include the safety of operators and other personnel and protecting the machines themselves. Secondary concerns include durability, reliability, and security, which also contribute to safe operation. The operator needs to be on the jobsite to perform the work at hand and needs the equipment to be reliably ready. Rugged radio remote controls are ideally suitable for highly demanding tasks in diverse environments and weather conditions. Operators rely on durable, high-quality products that react safely and dependably in all cases. In addition, customers and operators require systems that are serviceable and supported by the manufacturer.

Worldwide service networks need to offer quick and competent personal service around the globe, wherever the customer may be.

Another important question is customization. Operators are increasingly requiring tailor-made products that perfectly fit their needs, not only for an ideal interface for the operator but also for the optimum operation of the equipment. Most original equipment manufacturers have their own unique way of designing controls layout, and radio remote control systems are no exception. They are routinely designed to complement this layout to provide consistency for the operator.

The general operating environment of the machine or equipment typically dictates whether remote control operation is feasible, efficient, or safe for the operator. At the core of radio remote controls is the radio technology. Due to the various operating environments and types of equipment, the frequency management of these systems is essential when evaluating radio remote control systems. Another critical point is the capability to engineer the type of system that provides the optimal

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

11232021_FPJ_Clansman_Ad.pdf 1 11/30/2021 8:24:04 AM

balance to the operator, equipment, and the required functionality. This includes the type of transmitter the operator uses, how it is designed and configured to maintain consistency with the cab or control station, and the everyday demands of the task and the environment. Functional safety of commands has also become a requirement for the radio remote control of modern machines, which require radio remote control systems that can be seamlessly integrated while maintaining or exceeding the mandated safety levels for control.

Worldwide acceptance of safety standards such as the machinery directive ISO 13849-1, ATEX, IECEx, NEC, and others may drive many functional requirements of a radio remote control system.

Training challenges As with any change, there is always a learning curve when adapting to a radio remote control system. However, the extent of this curve depends on the careful selection of radio control solutions to ensure they match the natural movement of the operator with the application. Training should focus on slow and steady progress in a controlled environment, and the types of training depends on the complexity of the application and its standard operating procedures.

Training options are also often subject to the specific criteria defined by the employer, the manufacturer of the equipment, or government regulation. HBC-radiomatic offers safety options for radio remote control systems to assist with the training of new operators on various pieces of equipment. Operator-specific system and feature access can be implemented via smart access cards to ensure the available control options fit to the experience and skill level of the operator.

Radio controls have become a valuable tool for the safe operation of mobile and industrial equipment in all types of environments. As fluid power markets continue to evolve with new applications and safety requirements, radio control manufacturers must invest in developing new features and functions to help customers optimize efficiency and economic viability of their systems. With almost 75 years of leadership and development of safe radio remote controls, HBC-radiomatic has been a cornerstone of this growing industry.

COVER STORY

Grip on Reality

Pneumatic Tooling in Automation Robotics

By Frank Langro and Mike Guelker, Festo

A

s implementations of stationary and autonomous mobile robotics grows, the focus on innovations in end-of-arm tooling technology intensifies. End-of-arm tooling innovation falls into two broad areas.

The first involves designing new and improved specialized tools for performing single-purpose tasks such as gluing or screwdriving. In the second, design engineers work toward solutions that expand flexibility in picking and placing, holding, and clamping. The greater the range of objects grasped by a gripper, the more a single robot can do and do efficiently.

Pneumatic- and vacuum-powered grippers are applied in numerous industries and applications due to their small-form factor and high-force capabilities as well as the lower relative cost of pneumatics compared to servo-electrics. Pneumatics and vacuum are also ideal for adaptively gripping variable shapes and delicate, easily damaged objects. Servo-electric grippers are primarily used for precision, low-force gripping and have a narrower band of applications compared to pneumatics.

In some cases, unique designs rather than force, size, and cost make pneumatics the ideal choice. In one recent customer application, a pneumatic cylinder incorporated a vacuum assist and blow-off function via a hollow through rod on the cylinder. Compressed air flowing from the through rod removed debris and protected the workpiece surface.

Demand for flexible automation The COVID-19 pandemic has accelerated interest in flexible automation. Automation reduces worker density, lowering the risk of airborne germ transmission. Flexible automation also helps lower dependence on a labor market in which too few skilled workers are applying for open positions and serves to counteract the rising price of labor.

The development of autonomous mobile robots has moved robotics into new applications. Robots today, for example, can sanitize areas of a facility between shifts and other transition periods. The implementation of robotics for these tasks makes it possible to sanitize more often, thus protecting patients, guests, staff, and workers in hospitals, hotels, and plants. Due to the variety of tasks diverse types of grippers could be needed to accommodate different sanitizing tasks.

New materials, controls, manufacturing innovations such as 3D printing, and energy management for greater sustainability are driving innovation in robotic gripping. The ideal gripping solutions are typically lightweight and handle a variety of objects. This means that most gripping solutions no longer consist solely of heavy-duty metal parts. Today, 3D-printed and molded parts are increasingly incorporated into grippers. The speed and versatility of 3D printing allows for customized gripper fingers to handle specific objects. Companies that WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

can 3D print gripper fingers internally are less susceptible to supply chain disruption and better equipped to make repairs and modifications rapidly, which positively impacts uptime and productivity. A rapid prototyping capability provides companies with greater agility and can help them adapt to a rapidly changing environment.

Artificial intelligence Artificial intelligence and smart pneumatics also play a part in furthering pneumatics gripping applications. AI, smart pneumatics, and gripping are simply a natural fit. The ability to adjust and control grip force based on the attributes of the object is useful in applications in which the objects being grasped can vary. As the AI system recognizes TM the object, with a pneumatic gripper pressure can be adjusted to apply Robot with parallel grippers for versatile picking and placing boxes in a warehouse. the appropriate gripping force or vacuum level to hold the part securely without causing damage. with these food items, they gently shape around them without harm.

Adaptive grippers in a bakery gently grasp dough in a high-speed pretzel-making process.

(Continued from page 13)

Autonomous mobile robots Stimulating profound change in automation is the marriage of autonomous robotic mobility with flexible gripping. In manufacturing and end-of-line packaging, work comes to the robots; the robot does not go to the work. Using autonomous mobile robots with flexible gripping, robots travel safely among humans and go to the work. This is happening in hospitals and distribution centers were people and robots safely inhabit the same environment. For these applications, innovative, compact, portable, and low energy consumption compressors are being introduced.

The most common types of industrial pneumatic robotic grippers are parallel, three-finger, angled, and vacuum. Parallel grippers, the most frequently applied, do just what their name implies: two slides either close parallel to the workpiece to grip its outside edges or open out to put pressure on inside walls.

Three-finger grippers are used to center the workpiece between the fingers, which are offset by various angles. The three fingers slide the workpiece to the gripper’s center, holding the workpiece snugly. A variation of the angled gripper is the radial gripper: The fingers open a full 180˚, which is useful where vertical space is limited. Fully open radial fingers can rest just above or below the workpiece and close when it is in position. Vacuum grippers can be as simple as a single suction cup or as complicated as a 12-x-12 matrix with different configurations of cups fed vacuum as needed to conform to various shapes and weights of the load to be grasped.

Adaptive gripping is a new class of gripper. These grippers offer flexibility in the range of objects they can grasp.

today and their first response will be to say adaptive grippers are being developed for collaborative robotics. They would be partially correct.

Just as important as collaborative robotics, other industries are driving development principally because the price of automation is falling, and the capabilities are rising. For example, dairy farming is a labor-intensive agricultural business with low margins and a shortage of workers.

Due to technology advancements, there is a trend toward dairy farms incorporating robotic milking barns where cows learn to enter the barn to feed and, at the same time, be milked by a milking robot – all without human intervention. In the baked-goods industry, soft-adaptive grippers gently grasp breads and muffins. These flexible robotic systems can pick and pack mixed assortments to conform to each customer’s order.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

There are drawbacks to adaptive grippers.

They open and close more slowly than comparable stroke conventional grippers. Elastomeric materials wear faster than metal or hard plastic.

The size and weight of objects limit what these grasping devices can manage.

The greatest area of exploration for the future of adaptive gripping will be simulating the functionality of the human hand. The reason for this is simple. The hand offers the greatest efficiency – one gripper for a wide assortment of tasks. And with sensor technology providing

touch feedback there can be object manipulation, something grasping finger-based grippers cannot do.

Shorter product lifecycles, small lot sizes, and labor demographics are accelerating the need for adaptive systems. There are fluid power engineers today envisioning the possibilities and moving the industry forward. For a fluid power engineer, the opportunities for innovation in this field are endlessly gripping.

•

For items that are oddly shaped and not easily damaged, adaptive grippers with metal or hard plastic hinged fingers can be used for grasping.

For items easily damaged, such as produce or baked goods, the pneumatic fingers are made of a flexible elastomer. Some elastomeric grippers have flexible zones and nonflexible zones.

When pressurized, the flexible zones inflate and flex around the nonflexible zones, creating a nonmechanical hinge. Elastomeric fingers do not damage an item because both the elastomer and compressed air give when in contact with an object and thus offer a built-in cushioning effect. This inherent damping causes less shock during initial grasp, making these grippers ideal for baked goods, confections, fruits, and vegetables.

The continued advancement of adaptive gripping will rely in varying degrees on: • Tactile force sensors for measuring force and detecting different objects.

• Flexible printed circuit board with inertial and force sensors.

• Compact valve terminal with proportional piezo valves for rapidly and precisely ventilating and exhausting individual gripper fingers and swivel modules.

• Inertial sensors for recording the position of the gripper fingers.

• Elastic silicone skin for improving the haptics (the experience of simulated touch) and protecting the sensors.

• 3D textile knitted fabric of high-strength synthetic fibers for long wear.

• AI for reinforcement learning.

• Vision systems for identification and location sensing.

The Bionic Mobile Assistant Prototype I

ndustrial change demands new kinds of interaction among people, machines, and data. In the future, operators and robots will interact closely together, so Festo has been working intensively on systems that can relieve people of monotonous or hazardous activities while at the same time posing no risk. Artificial intelligence plays a significant role here. The BionicMobileAssistant is a prototype of a robot system that moves independently in three dimensions and can identify objects, grip adaptively, and collaborate with humans.

The entire system, which has been developed in collaboration with ETH Zurich, has a modular design and consists of three subsystems: a mobile robot, an electric robot arm, and the BionicSoftHand 2.0. First presented by Festo in 2019, the pneumatic gripper mimics the human hand.

With its unique combination of force, dexterity, and fine motor skills, the human hand is a true miracle of nature. To enable the BionicSoftHand 2.0 to replicate the movements of the human hand, compact valve technology, sensors, electronics, and mechanical components are integrated in the tightest of spaces.

The fingers and the opposable thumb are made of flexible bellows structures with air chambers surrounded by a firm yet yielding knitted fabric. This makes the hand light, adaptive, and sensitive, yet capable of exerting strong forces.

The pneumatic fingers are actuated by a compact valve terminal with piezo valves mounted directly on the hand.

In order to extend the maneuverability of the thumb and index finger compared with the first version of the BionicSoftHand, the developers 16

The SoftHand 2.0 can adapt its gripping force to a particular item.

increased the lateral swivel range of both fingers.

As a result, they now work well together and grip with great precision. Thanks to a 3D-printed wrist with two degrees of freedom, the hand can also move both back and forth as well as to the left and to the right. This means that gripping with a tight radius is also possible.

To increase the stability of the fingers, the air chambers now each contain two structural elements that function as bones. For each finger, a bending sensor with two segments determines the positions of the fingertips. The hand also wears a glove with tactile force sensors on the fingertips, the palm, and the outer sides of the robot hand. This allows it to sense the nature of the item to be held, and to adapt its gripping force to the particular item – just as people do.

In addition to the tactile sensors, the hand has a depth camera inside the wrist so it can visually detect the objects. Using it, the robot hand detects and grips a range of objects, even when they are partially covered. Once the hand has been correctly trained, it uses the collected data to assess the objects and distinguish good from bad, for example. The information is processed by a neural network that’s been trained in advance with the aid of data augmentation.

Electric arm The BionicSoftHand 2.0 is combined with a mobile ballbot and a lightweight electric robot arm – the DynaArm. The DynaArm can carry out fast and dynamic movements thanks to its lightweight design with highly integrated drive modules that weigh just 1 kilo (2 pounds).

For the ballbot, the developers chose a sophisticated drive concept: the robot balances on a

ball. This means that the BionicMobileAssistant can move freely in all directions. All the system’s energy supply is onboard: the battery for the arm and robot is located in the body; the compressed air cartridge for the pneumatic hand is installed in the upper arm. The robot is thus not only mobile but also works autonomously. The algorithms stored on the master computer also control the system’s autonomous movements.

The robot orients itself independently in three dimensions using two cameras.

Hand in hand with people The system would be perfect to directly assist people, as a service robot, as a helping hand in assembly, or to help carry out ergonomically strenuous or monotonous tasks.

It could also be used in environments where people cannot work because of hazards or restricted accessibility, such as maintenance or repair work, data measurements, or visual inspections. Imagine mobile robots carrying out simple tasks in areas of risk infection. Other future scenarios include robots bringing drinks and food to the table in restaurants or delivering medicines to hospital or nursing home patients.

Thanks to the modular concept, the BionicSoftHand 2.0 can be quickly mounted on other robot arms and is easy to commission.

Combined with Festo’s BionicCobot or BionicSoftArm, the gripper can, for example, form a completely pneumatic robot system that works hand in hand with people.

Shipments – Cumulative year‐to‐ date % change (2021 vs. 2020)

This graph of raw index data is generated by the total dollar volume reported to NFPA by CSS participants and compared to the average monthly dollar volume in 2018. For example, the October 2021 total dollar volume for pneumatic shipments is 102.1% of the average monthly dollar volume in 2018. (Base Year 2018 = 100)

The table above is expressed in terms of cumulative percent changes. These changes refer to the percent difference between the relevant cumulative total for 2021 and the total for the same months in 2020. For example, October 2021 pneumatic shipments figure of 16.1 means that for the calendar year through October 2021, pneumatic shipments increased 16.1% compared to the same time-period in 2020.

Pneumatic, Mobile and Industrial Hydraulic Orders 12/12 Ratio Each point on this graph represents the most recent 12 months of orders compared to the previous 12 months of orders. Each point can be read as a percentage. For example, 124.3 (the October 2021 level of the industrial hydraulic series) indicates that industrial hydraulic orders received from November 2020 to October 2021 were 124.3% of the orders received from November 2019 to October 2020.

Figure 2: Bent cylinder rod on an excavator.

Recognizing Misaligned Cylinders Misalignment of a cylinder occurs when the load is not applied along the centerline of the rod.

Many applications have a small amount of inherent misalignment because of clearance requirements due to cylinder size. It travels through an arc or in parallel to a single support guide. Most cylinder misalignment problems occur when the rod is extending. As the rod retracts, the cylinder tends to pull on the centerline of the rod, even when the load is misaligned.

During extension, misaligned cylinders tend to cock, bind, seize, wear, and leak, particularly near the end of the stroke when the cylinder is fully extended, as shown in figure 1. Overloaded cylinders are more likely to become misaligned during normal operation. Long cylinders tend to become misaligned because they sag. This requires that the head end of the cylinder and the rod itself be provided additional support that is spaced out as the rod extends from the cylinder. Ladder trucks and other equipment that extend booms with long-stroke cylinders require this type of additional support.

A cylinder with a bent cylinder rod will also misalign itself because the force is not exerted on the centerline of the rod. If the rod is misaligned, it tends to bend as the rod extends, as shown in figure 2. Another condition that may cause the cylinder rod to bend is lack of lubrication at the rod eye, causing the rod eye to seize at the pin. When the pin turns as the cylinder is extended, it can bend the rod next to the eye and cause it to break. This is a lubrication maintenance problem.

Whatever the cause of misalignment, side-loading will cause the rod bearing in the head end of the cylinder to wear “out of round,” causing the cylinder to leak at the rod seal. This is not a reasonable wear condition for a cylinder.

If two cylinders are connected by a machine member (crane boom or a loader bucket) such that they are mechanically linked, then they will have a tendency to bind or cock because the loading on the cylinders isn't equal. This is likely to happen when each cylinder is equipped with a

counterbalance valve to prevent the load from dropping, but the valves open at different set points (figure 3).

Misalignment of two cylinders that receive fluid from a common source can also occur if the load is not equally distributed to each cylinder (figure 4). For example, on a garbage truck, if two cylinders that compact the load from each side of the body unit encounter a solid object (e.g., a car engine) on one side, the sweep blade will be twisted as the side under load stops and the side without a load moves forward. A problem of this type is aggravated if the relief valve pressure has been increased to compact bigger loads. In severe cases, the cylinders may break loose or damage the compactor body.

A cylinder rod will leave telltale signs of misalignment, including scuff marks that show on one side of the rod when it is extended, a bent cylinder rod, and uneven wear side to side in the rod-eye and cap-end clevis. This would not include oval-shaped eyes that wear straight across the pin, which is caused by a lack of lubrication or extended use. Another way to detect misalignment is to watch the cylinder as it extends under load to see if it cocks and bows to one side when it stalls near the end of the extension stroke.

Misalignment can cause the piston to cock and gall the cylinder tube I.D. When the cylinder rod cocks, rather than riding smoothly in the bore, the piston is thrust against one side of the bore, causing metal-to-metal contact. Continued operation galls the cylinder bore and wears the piston on one side. Boring, or at least honing, is required to rebuild the cylinder, and piston replacement may be necessary.

When a cylinder is installed, the cylinder body and rod should be perpendicular to the clevis pins. The pins should be parallel to each other.

The cylinder should also be parallel to the arc of travel in pivoting applications. A swivel rodeye (figure 5) may be used to minimize any side loading to accommodate unavoidable “misalignment” between the cylinder rod and the driven object.
