PILOT PROJECT: INDUSTRIALIZED ECO-DESIGN OF A CONTROL ARMREST

In recent months, a pilot project has been created at elobau: the redesign of a control armrest with a focus on industrialized eco-design.

As part of a university thesis, max Krohmer has been working on the design of such a control armrest over the past few months. t he result is a design and material study, which is designed according to the principles of the circular economy with regard to the design and the development and manufacturing process. the work is to be understood as a study and can serve as a basis for further considerations with new materials and revised design. it gives an outlook on future, more sustainable products that focus on a more responsible use of resources and the environment.

With regard to the recycling process, the number of materials used is kept as low as possible. in addition, they can be quickly and easily separated from each other, and screw connections are avoided as far as possible. the stainless steel serves as a frame and as a support for the Karuun components. the Karuun in turn houses the controls and protects the electronics. the design is to be reimagined with the capabilities of the materials used.

Case Construction Equipment To Launch Wheeled Excavator Range

CASE announces the launch of a four-model E-Series wheeled excavator range, with a fifth, larger model joining the series in the future. The machines will be built under an existing supply agreement with South Korean manufacturer Hyundai Construction Equipment.

The CAsE wheeled excavator lineup will include the conventional tail swing WX140E and WX160E, along with the short radius WX155E sr and the WX175E sr these four models will be joined by a conventional tail swing WX210E at a later stage.

Features include:

• smooth operation and maximum control thanks to proven Bosch rexroth Load i ndependent Flow s haring hydraulic systems on the four smaller models.

• Durability, reliability and efficient roading capability thanks to heavy-duty ZF axles and hydrostatic transmissions.

• Enhanced site safety thanks to large operator cab with CAsE maximum View monitor enabling 360° view cameras and additional rear radar.

• m aximum comfort cruise control, optional ride control and joystick steering.

• operate on a range of biodiesel, HVo, and other synthetic fuels thanks to Cummins s tage V diesel engines with no requirement for exhaust gas recirculation (EG r ) Customisable specification t he new CA s E E- s eries wheeled excavators will boast proven wellestablished quality components. t hey will be available in a range of lower frame layouts, with several combinations of front and rear dozer blades plus front and rear outriggers. upper equipment will comprise a choice of mono or two-piece main booms for all machines except the WX175E sr , which will be supplied with a two-piece articulating boom only. standard cruise control will make travel between work sites easier while moving material in a work site is made more efficient by the optional ride control and even more so by using joystick steering controls.

Proven technology t he new CA s E wheeled excavators are powered by E u stage V compliant Cummins diesel engines. the four smaller models will use a Cummins B4.5 engine, delivering an above industry standard, outstanding maximum power of 129 kW, while the WX210E will come with the larger B6.7, offering up to 145 kW maximum power. t he engines feature a highly efficient exhaust after treatment module, incorporating a diesel oxidation catalyst (DoC), selective catalytic reduction (sCr) and a diesel particulate filter (DpF). t he engines are capable of operating with a range of fuels to suit the customer. t his includes B7 and B20 biodiesel, hydro treated vegetable oils (HVo) and gas-to-liquid (GtL), coal-to-liquids (CtL) biomass-to-liquid (BtL) paraffinic fuels. the WX140E through to the WX175E sr all use a Load independent Flow sharing hydraulic system from Bosch rexroth. t his delivers smooth, progressive control for the operator, while enhancing multi-function operation of the boom, dipper arm and bucket functions. A pressure compensator is built into the control system, to allow flow sharing performance for simultaneous travel and boom operations. the largest WX210E will come with an open center hydraulic system with Electric positive Flow Control, from Kawasaki. this uses a twin-pump layout, offering the power distribution required for smooth, productive operation. An electro- hydraulic proportional pressure reducing valve helps to reduce fuel consumption and boost performance. o perators can also benefit from an optional automatic digging brake and a fine swing control, to further ease control of the machine’s movements. An auto safety lock, similar to the system found on the CAs E E-s eries crawler models, prevents unwanted movement of the machine’s upper structure when the gate lock is released.

With no need for complex exhaust gas recirculation (EGr) system to comply with stage V requirements, the maintenance cost is much reduced. in addition, fuel filter service intervals are 1,000 hours and engine oil and filter intervals are set at 800 hours, further maximise machine up time for the operator.

Cab specifications improve operator comfort the E-series cab features a telescopic steering column with two tilt points, to make it easier for operators of all sizes to find a comfortable driving position. the windscreen has parallel wipers in both the upper and lower sections for the widest possible coverage and the machines can be supplied with an optional rearview camera on the right-hand side. the CAsE 360° maximum View monitor is also offered as an option, along with a rear-mounted radar for maximum visibility and safety. t he CA s E m aximum View m onitor uses four cameras, mounted around the machine, to provide a 360 ° aerial view. this provides the operator with a complete view of the machine on the work site, increasing safety and visibility and preventing potential collisions. the optional radar alarm can be set to five distances from the machine, warning the operator of any possible collision to the rear or the sides of the excavator. six LED work lights are standard, further improving visibility in poor light conditions. t he monitor provides EC o guidance for the operator, showing a range of data including idle times to help the driver to improve their performance and productivity while working. proportional joystick controls are standard, with a forward/reverse selection switch in the lever head. the lever also contains a front axle oscillation lock and a detent feature. t he operator can select within the monitor menus up to 10 pre-set auxiliary hydraulic flow and pressure settings. this makes it easier to inter-change hydraulic attachments, with hydraulic flows suited to each work tool. the right-hand joystick also has a switch to activate one-way or two-way auxiliary flow.

An 8” touch-screen monitor provides access to a menu system that controls all functions of the machine. A secondary screen is available for cameras. t he operator can navigate the main screen through a jog-dial controller, that also controls the engine throttle. this jog-dial has 10 engine rpm positions.

Joystick steering is optional, as is a smart key with push-button start.
