Vehicle for materials handling and other industrial uses
First Claim
1. A heavy-duty hoisting apparatus adapted for use in an industrial environment, comprising:
- a heavy-duty frame;
a hoisting mechanism mounted with the heavy-duty frame;
a switched reluctance (SR) motor operably engaging the hoisting mechanism for lifting and lowering a load; and
a digital control system coupled to the SR motor adapted to control the SR motor individually and to control the hoisting mechanism.

Abstract
A heavy duty wheeled vehicle for an industrial environment is electrically driven by one or more switched reluctance motor traction drive system connected to the wheels. The switched reluctance motors are powered by an electrical generator that is driven by an engine, such as a diesel engine, which may run at a substantially constant RPM. A digital control system provides operator displays and controls power conversion from the generator, as well as providing maintenance and control functions for the switched reluctance motors. A heavy-duty hoisting apparatus electrically drives a hoisting mechanism using an SR motor, providing power for lifting a load. The heavy-duty hoisting apparatus may include an engine and generator or provide power to the SR motor from an external source.
