Driver Controller

The Curtis PMC Transistor unit provides smooth, totally stepless control of the truck’s travel speeds. The design provides 275 amps capability and features: fault detection and thermal protective slowdown; adjustment for plugging, current limit and acceleration; access forward and reverse contractor actuation and a static return-to-off system.

Hydraulic Components

Pump: High volume motor-driven gear type. Hoist Unit: A single centered high-lift cylinder design (large 63mm ID) with hard-chrome plated piston gives smooth lift action. Tilt Cylinders: Two rugged, double-acting, piston-type cylinders. Pivot-type mounting permits self alignment. Lower Control Valve: Allows controlled lowering speeds. Hydraulic Reservoir: Provides a large volume of oil, reducing oil heating and allowing higher system efficiency.

Safety

Yale industrial trucks are equipped with certain safety devices as standard equipment. For example, all high-lift trucks are furnished with a load backrest extension, and high-lift rider trucks come with an operator’s overhead guard, operator’s restraint, and vertical battery restraint. When remote elevating control is specified, an operator’s work platform is supplied. Yale will supply only trucks equipped with required safety devices and strongly urges that these trucks be operated with the safety devices supplied. Furthermore, Yale will not assume any liability for injuries or damage arising from or caused by the removal of any safety devices from any Yale product.
