Hyster Company has launched a series of lift trucks in the 55,000 lbs. to 70,000 lbs. lifting capacity range. The Hyster H550-700HD models combine a host of new features including the ComforCab II operator compartment, developed for enhanced operator comfort to maximize productivity. In addition, the hydraulic system has been redesigned for optimal reliability and to lower the truck's operating cost. With its new "Power-on-Demand" load-sensing hydraulic system, the hydraulic fluid is only pumped when the system is required to do work. At low load conditions, drivers won't need to rev the engine to receive fast hydraulic speeds. This system leads to lower hydraulic oil temperature, extended life of hydraulic oil, filter, hoses, seals and components, and simplified plumbing with a reduction in the number of connections and O-ring face seal (ORFS) fittings. The lifts trucks also feature a new cooling system design capable of giving heavy duty performance, even at 110-degree ambient temperatures. For more information visit www.hyster.com.
