Crane Operator Certifications LOADING
Besides Raising Industry’s Safety Bar, Certification Elevates Operators’ Industry Standing
By Lucy Perry CEG CORRESPONDENT
SINCE 2018, OSHA has required crane operators to be certified by an accredited third party. To become certified, operators must complete an assessment of their knowledge, skills and competencies. More than simply theoretical learning, certification validates an operator’s skills and competencies. It helps reduce risk, empowers operators to attain a higher work ethic and raises the bar on safety in the crane industry.
CCO Services (CCO, formerly the National Commission for the Certification of Crane Operators (NCCCO), believes certification demonstrates a mastery of highly
specific skills and protocols.
“Certified individuals have completed assessments … to prove they meet standardized safety and technical requirements,” said the organization.
This verification of abilities helps ensure that only those meeting industry standards work on projects, said CCO.
Certification is “a testament to the competency and expertise of your employees in operating cranes,” said the North American Crane Bureau (NACB).
By investing in crane certification, a contractor provides employees with the opportunity to develop specialized skills, added the organization.
“Certification improves jobsite safety, reduces the risk of accidents and boosts
overall productivity and efficiency.”
It Pays to Be Certified
While operators can earn certificates and qualifications after completing a specific course, certification goes beyond just a piece of paper.
Certificates often do not include a rigorous competency evaluation, said CCO.
And qualifications can encompass a broad range of skills and experiences depending on the assessor, the organization said.
“Certification, particularly in construction, stands as the most reliable credential,” said CCO, one of several U.S. certifying organizations.

Mobile and crawler cranes
Because it combines validated skill and safety requirements, certification supports both professional growth and public safety.
The National Center for Construction Education and Research (NCCER) believes its credentials provide immediate credibility in the hiring process.
“NCCER credentials [give] certified students an advantage in attaining entry-level employment,” said the training and certification organization. “NCCER accreditation provides organizations a full workforce development solution.”
That solution is to deliver standardized training and assessment programs for industry-recognized, portable credentials.
“Accredited organizations must meet and maintain established standards and criteria to ensure integrity in program administration,” said NCCER.
Certification requires consistent demonstration of competency, as shown through industry-aligned exams and practical assessments, said CCO.
“Additionally, certification programs set and uphold standards through job task analyses.”
That in turn keeps the certification relevant to real-world job demands, said CCO: “Certificates are typically created by a trainer or employer.”
Certifying agency regulatory standards enhance the operator’s credibility and give employers confidence in hiring, said the organization.
“Certification provides a clear and reliable pathway to demonstrate professional competence, making it a solid choice over qualifications alone.”
Earning a certification can greatly impact an operator’s career, said CCO. Certified operators can have higher job security and better opportunities for career advancement.
Plus, being certified can be a factor in promotion and salary increases, said CCO. “It proves a commitment to maintaining essential skills in a demanding field.”
In fact, many employers prioritize certified professionals for roles that carry higher responsibility, said CCO.
Whom to Turn to for Certification?
When OSHA finalized its crane operator qualification rule in 2018, it included rules requiring operator certification organizations to be accredited.
The two accrediting bodies are the American National Standards Institute (ANSI) and the National Commission for Certifying Agencies (NCCA).
There are four crane operator certification organizations currently accredited by ANSI:
• CIC — Crane Institute of America Certification
• EICA — Electrical Industry Certifications Association
• CCO Services LLC
• NCCER — National Center for Construction Education and Research
Two organizations are accredited by NCCA:
• CICC — Carpenters International Certification Council
• OECP — Operating Engineers Certification Program
As CCO notes, not all certification bodies are accredited for all the programs they offer.
Employers can verify for themselves which programs are included in the accreditation scope and which bodies are accredited.
If you’re an employer setting up a certification program for your staff, you should first determine which types of cranes they’ll be operating and all relevant certification programs available.
“This preference can mean increased earning potential and access to specialized roles that uncertified individuals may not qualify for.”
It also not only marks operators as knowledgeable but also as dedicated to upholding industry standards.
Certification also strengthens the crane industry, ensuring industry-wide standards are met and promoting safe work environments for everyone, said CCO.
“When employees are certified, employers benefit from lower insurance premiums” and reduced workplace accidents. They also enjoy the confidence that their workforce meets stringent, defensible standards.
“Certified professionals support safer job sites, which in turn leads to fewer accidents, less downtime and greater efficiency across projects,” said CCO.
Understanding the different types of operators and the certifications they need is crucial, blogs construction recruiter Industrial Trade Services (ITS).
Mobile crane operators operate cranes that are mounted on trucks, crawlers or wheels. Stationary, tower cranes are used for lifting and moving heavy loads in construction sites where materials need to be lifted to great heights. Overhead crane operators operate rigs used in manufacturing facilities, warehouses and storage yards, moving heavy loads within a confined area.
As ITS notes, each certification available for crane operators is focused on a specific type of crane or crane operation.
CCO offers certifications in several categories, including mobile and tower crane, as well as rigger signal person, crane inspector and lift director.
CIC offers a long list of operator certifications including articulating, telescoping and lattice boom cranes, boom truck and rough-terrain cranes.
International Union of Operating Engineers (IUOE) certifies crane operators in categories including mobile crane operation and tower crane operation.
NCCER’s certification list includes not only mobile cranes but industrial/all-purpose cranes, rough- and all-terrain cranes and truck-mounted cranes.
NACB offers advice to contractors wanting to implement an operator certification program: First assess your staff’s training needs. You’ll want to determine which types of cranes staff will be operating and the relevant certification programs available.
“It’s essential to choose the appropriate certification program that aligns with the specific requirements of your industry and job site,” said NACB.
Next, partner with a reputable training provider with experienced instructors, a comprehensive curriculum and a strong training track record, suggests NACB.
“Verify that the training provider is affiliated with recognized industry organizations to ensure compliance with industry standards.”

Next, it’s time to enroll your employees in a training program. They usually combine classroom instruction with hands-on simulation and practical training.
This combination training format helps develop the necessary skills for safe and efficient crane operation, said NACB.
Enthusiasm is a help, too.
“Encourage your employees to actively participate … ask questions and seek clarification to make the most of their learning experience,” said the organization.
Because hands-on training is critical, an employer should ensure operators have access to the necessary equipment and facilities to practice their skills.
And, those skills should be practiced under the guidance of experienced instructors, said NACB.
“Practical experience reinforces the theoretical knowledge gained during the training program and builds confidence in operating cranes safely and effectively.
Because most crane certification programs include a written and practical exam, do work with your employee to ensure they understand the content.
Content may cover crane components, load charts, rigging, safety procedures and signaling, said NACB.
“Additionally, provide opportunities for your employees to practice their skills in simulated or real-world scenarios to prepare for the practical exam.”
With training complete, operators will take the certification exam to evaluate their theoretical knowledge, practical skills and understanding of safety protocols.
“Successful completion of the exam leads to the issuance of a crane operator certification, which is typically valid for a specific period, often five years,” said NACB. “Encourage your employees to stay updated with changing industry regulations.”
NACB also stresses the importance of employers providing opportunities for ongoing training and recertification.
“Obtaining crane certification for your employees is a valuable investment in their professional growth and the safety and efficiency of your operations.”
From the Operator’s Mouth
Phil Robbins, a veteran Detroit, Mich., crane operator, credits his CCO certification for helping navigate challenges in the field.
“The CCO certification … demonstrates my expertise and commitment to operating cranes in the safest, most efficient manner possible,” he said.
Likewise for Dan Dickey, a crane operator of Cianbro in Pittsfield, Maine, who has been recertified four times and compiled multiple certifications along the
way.
He started with a CCO mobile crane certification, and added signal person, rigger, lift director, tower, overhead, digger derrick and dedicated pile driver.
Dickey is now a crane operator instructor, teaching people within Cianbro how to use the machines, prepare for tests and do hands-on practical training.
“CCO requires recertification every five years, and I think that’s extremely beneficial,” Dickey said. “We brush up on the standards and practices, and it gives us a chance to connect with operators to find out what is happening on our various projects.”
Dickey believes five years is a good period of time to recertify.
“The cranes and lifts keep getting big-
ger and more technical,” he said. “It’s good to bring people back in and review safety protocols that change in that time.”
In an industry where precision, safety and expertise are paramount, obtaining national certification is critical for any crane operator, believes CICB.
Certification “ensures adherence to high safety standards, opens doors to a wider range of job opportunities, enhances career advancement prospects.”
It also contributes to industry-wide consistency, said the crane inspection and certification organization.
“Furthermore, it provides professional recognition, strengthens regulatory compliance and ultimately supports a safer and more efficient work environment.”

NORTHWEST CRANE’S LIEBHERR FLEET TURNS AROUND TU NA OUND PROJECT R R
During the high stakes period of a plant turnaround, Northwest Crane Service relies on a fleet of Liebherr cranes to complete a series of critical lifts — all while ensuring maximum safety and customer satisfaction.
A plant turnaround, often called an outage or shutdown, is a scheduled period when a facility conducts maintenance on equipment and utilities.
Northwest Crane Service was chosen as the crane service provider for a plant turnaround in fall 2023 at a site in Kansas. Utilizing Liebherr equipment and backed by months of planning, technical engineering and ongoing communication with the customer, Northwest Crane Service maintained high productivity, kept the turnaround on schedule, and ensured the project’s safe completion.
Critical Selection
At Liebherr USA, Co., safety is not just a buzzword, every crane has a sophisticated safety concept. With these safety features in mind, crane selection played a critical role in the timely completion of this project as there were several complex lifts.
The most difficult lift included a 220,000lb. ammonia converter. This lift not only required a large crane, but one that could meet the customer’s ground bearing pressure requirements.
Northwest had the ideal solution by utilizing the Liebherr LR1600/2-W, narrow track crawler crane. As the only LR1600/2-W in the United States, it was clear that Northwest’s utilization of the
Liebherr crane was the ideal solution for this job as it could easily lift and maneuver in a tight space.
The Liebherr LR 1600/2-W excels in heavy lift applications across a wide variety of industries, according to the manufacturer. The crawler offers both standard and narrow travel gear allowing it to move on tracks between tight erection sites. The LR 1600/2-W also provides class lifting capacity with numerous enhancing attachments.
“Safety, innovation and teamwork are in the DNA of how we operate at Northwest Crane Service. And we use these same parameters when selecting our equipment — which is why we have a fleet of exclusively Liebherr cranes,” said Andy Hodges, owner of Northwest Crane Service.
In total, Northwest deployed 10 Liebherr cranes that were operated, rigged and supervised by a 56-member team. Working day and night, the project took place over 57 days and 12,357 man-hours.
Northwest operated and maintained the fleet of mobile cranes to provide rigging and hoisting support for a variety of technical components, tools, and pipe during the mechanical shutdown of the plant. Due to the tight timeframe, it was essential that Northwest personnel stay on the customer’s schedule and meet their lifting needs in an efficient manner.
Setting the Standard
In addition to the LR 1600/2-W crawler crane, Northwest utilized a fleet of Liebherr mobile cranes including the LTM 1650-8.1, LTM 1230-5.1, LTM 1130-5.1, LTM 11105.1, LRT 1100-2.1 and LTM 1070-4.2.

Due to the tight timeframe, it was essential that Northwest personnel stay on the customer’s schedule and meet their lifting needs in an efficient manner.
Not only are Liebherr mobile cranes efficient for the plant turnaround, but they offer powerful, long telescopic booms that can reach incredible heights quickly and easily. As flexibility is a high priority for Northwest, the mobile cranes also can be configured quickly using functional lattice extensions, folding jibs, fixed and luffing lattice jibs.
“Liebherr’s commitment to producing the safest and most innovative machinery on the market coupled with the collaborative nature of our relationship allows Northwest to provide the industry leading service we are known for day in and day out,” said Hodges.
In total, Northwest deployed 10 Liebherr cranes that were operated, rigged and supervised by a 56-member team. Working day and night, the project took place over 57 days and 12,357 man-hours. Northwest successfully completed multiple complex and tandem crane lifts with zero incidents, owing to Liebherr’s excellence. (All photos courtesy of Liebherr.)

The new Link-Belt Cranes 65-ton 65|RT is already quick to work, assisting the construction of an overhead transmission line project led by Centerline Drilling of central Oregon. Located in the small town of Lexington, Ore., the project is making use of the 65|RT’s ease of operation and smooth job site travel.
Utilized to set rebar cages and anchor bolt cages into 17 drilled pier foundations, the 65|RT is proving itself to be an incredibly useful machine. The cages ranged in size from 8 ft. in diameter by 30 ft. long to 11.5 ft. in diameter by 35 ft. long, weighing up to 16,000 lbs.
Centerline operator Hunter Magnan said the crane handled the cages flawlessly in every configuration. With three years of operator experience, Magnan said the 65|RT was a great entry point to rough-terrain cranes for him, logging hundreds of hours on the machine during the time he operated it.
From the crane’s seamless controls and smooth jobsite travel to its ergonomic cab, including features like LED lighting, vision package and a simple-to-use Pulse LMI system, Magnan said he would definitely recommend the 65|RT. For anyone in need of a midsize picker with outstanding capacity at radius and unmatched maneuverability, the 65|RT is a do-it-all machine, the manufacturer said.

The SK6000 can now operate directly from grid power — or, at sites without power network access or with supply stability issues — via batteries or hydrogen generators
& StrongCLEAN
Mammoet’s SK6000 — the world’s strongest land-based crane — has been tested for fully electric operation. It now offers zero-emission capability to projects taking place anywhere in the world.
Through this innovation, Mammoet is demonstrating its commitment to helping customers reduce the emissions profile of large projects. The technology also reduces the noise generated by crane operations, resulting in a better work environment where communication is easier.
In turn, large projects are made safer, cleaner and easier to finance.
The SK6000 can now operate directly from grid power — or, at sites without power network access or with supply stability issues — via batteries or hydrogen generators.
Testing was carried out using two 600kWh Battery Boxes from power supply specialist Bredenoord, connected in series to deliver 1,200 kWh; around the same output as 20 electric cars.
Connection took a day shift, in parallel with test weight reconfiguration activity. This proves that the use of batteries has minimal impact on site operations.
Battery packs capable of operating the SK6000 are becoming widely available, in standard 20 ft. shipping container form factors, which can easily be mobilized to and from site.
Niek Bezuijen, global sustainability advisor at Mammoet, said, “Thanks to this test we can now say that the SK6000 operates fully zero-emissions on-site.
“Electrification isn’t a matter for the future of heavy lifting — it is needed now, and through innovations like this Mammoet can help its customers lead on safety, efficiency, sustainability and cost”.
Mammoet Crane Now Offers Zero Emissions
By plugging into a medium voltage network — commonly available in heavy industry — the SK operates directly from the grid. At port facilities, so-called “shore power” connections, typically used to prevent cargo vessels idling at port, are capable of powering the crane.
Battery functionality offers a further option, with the additional benefit of being chargeable from lower power networks. The significant periods of time between individual ring crane lifts allow the chance for battery packs to recharge.
Hydrogen generators can be used where neither grid power nor battery power is an option, for example at remote sites without significant infrastructure.
With SK6000 electric functionality confirmed, Mammoet can now offer a fully zero-emission, low noise marshalling service to customers in the offshore wind sector.
Oil and gas projects benefit from complete elimination of carbon impact during the heaviest lifting scopes, at the same time as realizing the largest possible economies of scale from modular construction methodologies.
In the nuclear sector, reduced noise levels will enhance safety levels at complex new build sites while allowing projects to deliver lowcarbon energy in a sustainable way.
This project was part-funded by the Subsidieregeling Schoon en Emissieloos Bouwmaterieel in the Netherlands; a research and demonstration fund to develop zero-emission initiatives at construction sites.

SOARING AT ANY LEVEL SOARING AT ANY LEVEL
Tadano
Tadano’s new AC 5.250L-2, which features a 259.2-ft.-long main boom, this 5-axle machine is a versatile crane. And the maximum main boom extension of 98.4 ft. adds to its versatility.
With Tadano’s new AC 5.250L-2, which features a 259.2-ft.-long main boom, the five-axle machine is a versatile crane. And the maximum main boom extension of 98.4 ft. adds to its versatility.
All available main boom extensions from 19.0 to 98.4 ft. are selferecting. The available maximum system length of 357.6 ft. makes the compact AC 5.250L-2 ideal for urban applications, such as lifting air conditioning units over obstructions onto tall buildings. In addition, it is suited to the assembly of large tower cranes.
“Our AC 5.250L-2 is also top of the class when it comes to load moment which, at up to 736 metric tons, is one of the best on the market,” said Peter Kleinhans, a Tadano project manager.
The high-load moment is achieved with a working radius of 23 ft., a 44.3 ft.-long main boom and a load weight of 231,920 lbs. In addition, Tadano offers an optional heavy-lift attachment for loads of up to 305,780 lbs. on the short boom with additional sheaves.
Economical Use as Taxi Crane
Like the basic AC 5.250-2 model, the “main boom long version” also offers multiple transport configurations. The crane with 10 x 6 drive can be moved on cost-effective 16-in. steel wheels on public roads while complying with the 26,500-lbs. axle load limit with a considerable amount of equipment. That includes a 32-tonne Vario hook block and outriggers with a total weight of less than 132,300 lbs., transport brackets for extensions and up to 550 lbs.
of equipment
in the rear box.
In compliance with the 36,400 lbs. axle load limit with a total weight of 181,900 lbs., the AC 5.250L-2 can be driven on public roads with a 10 x 8 drive on 16-in. steel wheels. It can not only carry a 35-ton hook block, outriggers and a 39.4-ft. extension including transport brackets, but also 44,100 lbs. of counterweight and up to 1,100 lbs. of equipment in the rear box.
Sophisticated Counterweight Concept
The AC 5.250L-2 can pick up its maximum counterweight of 176,400 lbs. in three lifts: 109,300 lbs. with a radius of up to 22.3 ft. at a full radius of 360 degrees; two 33,500 lbs. with a radius of up to 42.7 ft. divided into 22,050 lbs.; and 11,500 lbs. for hanging on the right and left of the basic package.
If required, the counterweight can be divided into smaller pieces. For example, the 12,150 lbs. base plate can be picked up from a distance of up to 75.5 ft. in a full radius.
“Thanks to the standard IC-1 Plus crane control system, the possible radius can be increased considerably in certain areas of the slewing angle,” Kleinhans said.
Maximum flexibility in transport logistics is ensured by the division of the counterweight, with no element weighing more than 22,050 lbs. That means smaller trucks can be scheduled for transportation if space conditions on the construction site require it. New Tadano AC 5.250L-2 All-Terrain Crane Boasts 259.2 Ft. Main Boom

On Board: IC-1 Plus, Surround View
Tadano has equipped the AC 5.250L-2 with a range of standard features that benefit all current cranes in the Tadano AC family.
This includes the IC-1 Plus crane control system. It determines the maximum load capacity of the crane in real time for each boom position depending on the slewing angle of the superstructure. This means that the crane can always use the maximum available capacity — especially when lifting over the outriggers.
This advantage comes to the forefront when the counterweight is reduced, and the outriggers are not fully extended. The AC 5.250L-2 benefits from this, as its outriggers can be extended asymmetrically in five positions of 0, 25, 50, 75 and 100 percent.
The Surround View camera system is available as an option for the Tadano AC 5.250L-2, making it easier for the crane operator to optimally position the crane on the construction site, according to Tadano. This system uses six cameras to display the maximum possible extension widths of the outriggers at the crane’s current position in a computer-aided display.
“With Tadano Surround View, the crane operator can see on a display in the cab exactly how he needs to position the crane on the construction site in order to extend all outriggers sufficiently and ensure the required slewing radius,” Kleinhans said.” This eliminates the need for tedious and time-consuming measuring and trial and error when searching for a location, so that the crane is ready for use more quickly.”
The system also helps to better recognize pedestrians and cyclists while on the way to the construction site when turning.
Comfortable, Safe Workplace
When developing the AC 5.250-2, Tadano did not disregard the needs of the crane operator. The AC 5.250L-2 positions all noiseemitting hydraulic components away from the upper cabin. The amount of space in both cabs ensures a high level of operating
comfort. Safety is ensured by access steps, attachment points for the driver’s personal safety equipment and a step that can be extended from the undercarriage.
The optional pendant light and a load view camera ensure greater safety during operation. These can be mounted alternately on the boom head and on the extensions so that one system can be used for all configurations. When lifting over interfering edges with an extension, the available repeater is recommended for mounting on the boom head to ensure a wireless connection to the camera.
Ecological, Economical in Operation
On the engine side, the AC 5.250L-2 has the same drive that already delivers in the AC 5.250-2: The Mercedes-Benz engine with 530 hp output and a maximum torque of 1,917 lb.-ft. ensures decent acceleration and strong lifting performance. The HVO-compliant diesel engine meets the E.U. Stage V and U.S. EPA Tier IV Final requirements.
With Eco Mode, it also is economical: The engine only delivers as much power as the crane needs at any given time, according to Tadano. The corresponding calculations are made via the IC-1 crane control system, which includes a fuel-saving start/stop function.

Conclusion
With the AC 5.250L-2, Tadano has added a variant to the proven AC 5.250-2 basic model, which extends the range of applications of the versatile crane thanks to the 259.2-ft. long main boom. The high load moment of up to 736 metric tonnes in combination with the long system length of 357.6 ft. makes this crane an option for many applications where heavy loads have to be lifted to great heights and, thanks to its taxi crane properties, it is also an economical option.
