Replacing company's H550-700F models, the H550-700HD series trucks feature ComforCab II operator compartment, developed for enhanced operator comfort to maximize productivity, and Power-on-Demand load-sensing hydraulic system, which pumps fluid only as required. The latter 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 maintaining heavy duty performance, even at 110-degree ambient temperatures. The new series' electrical connections used throughout the trucks are sealed Deutsch connectors and perform in all weather conditions.
These and other features contribute to what the manufacturer notes is the trucks' low cost of ownership. The redesigned hydraulic system can reduce fuel consumption since the engine operates mostly in low RPM range, and can also extend the hydraulic oil change intervals. The wet disc brakes require minimal maintenance, while the friction discs last up to 20,000 hours. The Sy-Klone Air Pre-Cleaner is self cleaning, and extends air filter life. Finally, the powertrain protection system protects the engine and transmission by reducing power or shutting the truck down under prescribed conditions to avoid damage. Hyster Co. www.hyster.com
