F;T* Powering Business Worldwide A leading manufacturer of sideloaders and multidirectional sideloaders has teamed up with Eaton for its electrohydraulic mobile valve requirements. As a result of vastly improved steering control in comparison to the previous solution, the company has specified CMA090 valves in its new series of four-way sideloader forklifts. Bulmor Industries GmbH based in Perg, near Linz, Austria, is a specialist in material handling solutions, particularly for long, heavy or large items. The company, which has history that can be traced back to 1879, is renowned for designing and manufacturing machines to specific customer requirements, building its first forklift trucks in the 1960s and later specialising in the production of sideloaders. Today, Bulmor is one of the strongest brands in the sector, offering bespoke four-way sideloaders with lifting capacities from 2 to 10 tonnes, sideloaders with lifting capacities from 4 to 20 tonnes, and electric sideloaders with lifting capacities from 3 to 8 tonnes. For its latest four-way sideloader, which offers customized height and width to help maximise storage capacity, Bulmor sought an electrohydraulic mobile valve capable of overcoming a number of challenges. Specifically, the steering control of the individual drive wheels is of paramount importance, as Bulmor's Thomas Goesweiner explains: "Our fourway sideloader offers a fast and programmable multidirectional steering system, where precise control of the four independently steered drive wheels under various load conditions is imperative. Ultimately, steering comfort, precision and driver assistance are our leading requirements." As well as safe and smooth load control, the four-way sideloader features a mast shift function that can sometimes suffer from an overrunning condition where load inertia takes over control. Along with this challenge, Bulmor also required a high-efficiency valve solution able to reduce energy consumption. Performance and flexibility =v The answer arrived in the form of an Eaton seven-bank variable-inlet CMA090 valve, which is digitally configured with Eaton's Pro-FX® Configure software plus a DPS2-12 differential pressure valve. Chosen for its product performance and flexibility, the advanced CMA mobile valve with independent metering offers a sophisticated technology platform that streamlines and simplifies everything from

design and set-up to 'operation and optimisation. "All four wheels must follow a given steering algorithm without any delay or variance, regardless of load conditions," states Goesweiner. "Here, the CMA valve's flow control is providing the best steering performance we've ever achieved. This is due to a number of factors, not least 0.125 LPM resolution, fast electronic pressure and temperature compensation, and electronically calibrated sections to compensate for machining tolerances." The CMAs integral flow share feature with priority selection for the steering system also eliminates the need...
