ERP060VL Yale electric forklift specs & dimensions (2019 - 2026)

Yale ERP-VL Electric Trucks

Yale® ERP-VL electric trucks are available in 4,500 – 7000 pound capacities designed for demanding applications that require clean, quiet-running, heavy-duty capability. These trucks are very maneuverable and offer plenty of power and high stacking ability, while also offering excellent ergonomics, reliability and maintenance ease. Pneumatic tires provide more comfort indoors and greater capabilities for outdoor applications.

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, providing constant temperature and gradually adjusting performance to prevent damage to key components.

Automatic Park Brake

The ERP-VL features an 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” via an electrical solenoid within the park brake assembly. A manual override lever, located underneath the floor plate, is provided to disengage the brake if the truck has to be moved during service conditions in the absence of power on the truck.

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. The wet brake disc pack is positioned between two traction motors. These low pedal effort brakes require no adjustments and very little maintenance, yet provide a long service life.

Power Assisted Braking

Power Assisted Braking is accomplished via the VSM, which 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 an external fluid level sensor connected to an LCD icon/indicator on the instrument module. The standard Auto Deceleration System automatically slows the truck when the operator’s foot is removed from the accelerator pedal, extending brake life.

Hydraulic Components

A transistor-controlled hydraulic system is powered by a brushless, AC induction motor with wet spline. The motor and pump are mounted on rubber isolators for reduced noise and vibration. A combination of flexible wire-braid hoses and steel tubing is used to simplify the hydraulic plumbing. These hydraulic hoses are carefully routed and held in place to reduce possible damage.

Hydrostatic Power Steering

Hydrostatic power steering is standard, and the all-hydraulic design gives precise, reliable control while eliminating mechanical linkages and road shocks at the steering wheel. An infinitely adjustable tilt steering column provides excellent operator comfort and visibility.

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 cover gives easy access to components. A stamped steel, gas spring-assisted hood allows easy changing of the battery.

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 repositioned display is conveniently located in the upper right area of the operator’s compartment. The display allows an amber hour meter, LCD display for status codes and descriptions, battery discharge indicator with lift interrupt, all LCD icons/indicators for brake fluid, seat belt indicator, performance mode indicator, and parking brake indicator. The display also permits access for service technicians to adjust performance control settings, allowing the truck to be customized to meet customer applications. Additionally, extensive diagnostics allow service technicians to quickly troubleshoot problems. Operator selectable performance modes are standard. Options for operator passwords and a pre-shift operator checklist are also available.
