Drive
Yale AC Technology
Offers smooth acceleration with seamless direction change and regenerative braking. The controller converts battery power to three-phase AC power, and adjusts frequency and currents to meet performance demands. Performance control settings and extensive diagnostics are accessible by technicians through the dash display or a P. A. Master Controller. Utilising Controller Area Network (CANbus) technology, it monitors and controls key truck components and systems. The sophisticated Thermal Management System monitors component temperature and gradually adjusts performance to prevent damage to key components.
Controller Area Network (CANbus)
CANbus technology streamlines communications between truck systems through one main master controller. The dash display, traction controller, and pump controller are all regulated via the CANbus network. A connection point is provided for interface with a service PC.
Brake System
Hydraulic brakes are self-adjusting and self-energising for reduced pedal effort. The master cylinder is sealed to prevent contamination. A hand-operated park brake is manually adjustable and has an audible warning if the operator leaves the truck without applying the brake.
Hydraulic Components
The hydraulic system utilises an AC transistor Controller and a brushless AC induction motor. A flexible coupling joins the motor to the pump for long drive life and low noise. The motor and pump are mounted on rubber isolators for reduced noise and vibration. A combination of flexible wirebraid hoses and steel tubing is used to simplify the hydraulic plumbing. A dipstick allows easy checking of hydraulic oil without the use of tools. A 10-Micron full flow hydraulic filter located in the return line protects the hydraulic system from contaminants and helps provide long life. Additionally, a by-pass relief valve permits oil flow in the event of the filter clogging.
On-Demand Power Steering
On-demand power steering is standard, and the all-hydraulic design gives precise, reliable control while eliminating mechanical linkages and road shocks at the steering wheel. A five-position tilt steering column provides excellent operator comfort and visibility. A brushless motor operates at a very low speed when not in use, conserving energy and reducing noise levels.
Steering Axle
The steering axle is a one-piece ductile iron casting mounted on elastic cushions that reduce shock and provide a softer ride.
