General

General

This lift truck can be configured to operate with a 36V or 48V battery. Operator input/command signals are communicated to various electronic components via a CAN-Bus network. Pressure for lift, tilt, sideshift, and steering is provided by a hydraulic pump driven by an AC motor. The pump motor is controlled by an AC power amplifier (PPA).

Dual Traction Motor Trucks - Two independent AC motor/drive unit assemblies provide traction via a dual AC power amplifier (TPA). A multiple disc, oil bath type brake system is located internal to the drive units.

Single Traction Motor Trucks - An AC motor coupled to a differential type drive unit provides traction via an AC power amplifier (TPA). Trucks below S/N 10677 use automotive type drum brakes located on the drive wheels. Trucks 10677 and up use a multiple disc, oil bath type brake system located internal to the drive unit.

Serial Number Designations

The truck serial number consists of a three-digit model abbreviation, two-digit year of manufacture, two letter configuration code, and five-digit serial number.

Example: 470-12-xx12345

The two letter configuration codes (xx) are designated as follows:

•SM = Single (traction) Motor

•DM = Dual (traction) Motor

•HM = High Maneuverability (dual traction motor)

•L or SL = Single traction motor, Long chas sis

NOTE : The mast designation is not an indicator of the truck’s chassis or drive system.

High Performance lift (600A AC3 PPA )

Single traction motor; 5000 lb. capacity Long chassis (allows less down rating at height )

C60Single traction motor; 6000 lb. capacity

Performance Modes (L•P•H)

Three selectable performance parameters, L, P, and H, are configured for travel and lift speed, acceleration, and hydraulic flow for attachments.

L = low performance

P = medium performance

H = high performance

These parameters are set at the factory such that H will be maximum speed, L will be slower, and P will be an intermediate speed.

These parameters can be set to meet specific application requirements via FlashWare.

NOTE : This feature is not available on EE rated trucks.

Performance Reduction

The performance reduction (turtle) mode reduces the performance parameters in the L, P, and H settings. Turtle mode performance is also configurable via FlashWare.
