ERP100VML Yale electric forklift specs & dimensions (2022 - 2026)

AC Transistor Traction Control

AC technology offers smooth acceleration and directional changes, proportional regenerative braking and the Auto Deceleration System. The controller converts battery power to three phase AC power, and adjusts frequency and current to meet performance demands. Performance control settings and extensive diagnostics are accessible by technicians through the display or a PC. A Vehicle System Manager (VSM) utilizing CANbus technology monitors and controls key truck components and systems. The advanced thermal management system monitors component temperature and gradually adjusts performance to prevent damage to key components.

Automatic Park Brake

The ERP-VM lift truck features a standard automatic park brake that is applied by a spring when the truck is stationary. Upon sensing a demand at the accelerator pedal, the brake is released and held “off.” A manual override (located underneath the floor plate) is provided to disengage the brake if the truck has to be moved during service conditions or in the absence of power.

Wet Disc Brakes

The brake system features standard oil-cooled wet disc brakes which are internal to the drive axle housing, protecting them against dirt and moisture. These low pedal effort brakes require no adjustments and very little maintenance, yet provide long service life.

Power-assist braking

Power-assist braking is accomplished via the VSM. The VSM monitors brake line pressure. When this pressure exceeds a set threshold the VSM sends a signal to the traction controller to decelerate the traction motor proportionally to the brake pressure. The higher the brake pedal pressure being applied, the more quickly the truck will decelerate. The master cylinder is sealed and has a fluid level sensor that illuminates an icon on the display if low. The standard Auto Deceleration System automatically slows the truck when the operator’s foot is removed from the accelerator pedal, extending brake life.

Voltage

The ERP-VM lift truck uses an 80-volt electrical system for high performance and long run time to meet a variety of application requirements. An operator presence system reduces the possibility of inadvertent truck movement.

Frame

The frame is a unitized construction, stress tested for durability. An integral step on both sides of the truck is provided for easy entry and exit. The truck has a two-piece floor plate that can be easily lifted out for service access. An easily removable counterweight top cover gives easy access to components. A stamped steel, gas spring-assisted hood allows easy changing of the battery.

Steering Axle

The steering axle is a one-piece ductile iron casting mounted on elastic cushions that reduce shock and provide a softer ride. The Continuous Stability System (CSS™) enhances truck stability in a simple, maintenance free design, without compromising uneven surface travel. The “Zero Turn Radius” steer axle design allows for increased maneuverability.

Dual Drive Motors

Left hand and right hand AC drive motors are contained in the drive axle assembly. The outer end of each motor drives a wheel through a planetary gear transmission. The transmissions use helical gears with tooth geometry that is optimized to minimize gear noise. Each drive motor is individually controlled, allowing for a “zero inside turning radius” scenario that provides excellent maneuverability.

Operator Interface Display

The display is conveniently located in the upper right area of the operator’s compartment. The LCD display includes an hour meter, battery discharge indicator with lift interrupt, seat belt reminder and digital clock. Additional indicators are provided for travel direction, performance mode, brake fluid level, park brake and truck status. The display also permits access for service technicians to adjust performance.

Additional Features

Additional features on the ERP-VM series include an overhead guard, seatside directional control, operator presence system, 48” forks, non-suspension seat and seat belt. An infinitely adjustable tilt steering column, rubber floor mat, and electronic horn are standard.
