INTRODUCTION:

The purpose of this manual is to provide a safe, logical sequence of events for
inspecting and operating a Unit Rig MT Series rear dump truck equipped with an AC drive system and
the Unit Rig High Productivity Cab. For the convenience of the operators, information is provided
for both standard and optionally equipped trucks. This information can be disregarded if not
applicable.

• Before attempting to operate the truck, personnel must become familiar with systems and component
  operation. They must be trained in the proper operation of the truck and instructed on all
  guidelines and regulations in force in the area of the mine. Good safe practices should be
  followed in a common sense way.
• The drawings in this manual do not necessarily reflect all vehicle configurations.
• The information in this manual does not attempt to cover all details or variations in equipment nor
  to provide for every possible contingency to be met in connection with the inspection and safe
  operation of a truck.
• If there is any information in this manual that is not clear or that you believe needs to be
  addressed, please feel free to contact your local Unit Rig representative at any time or contact
  the company directly at the address on the
  back cover.

DESCRIPTION:

• The Unit Rig MT Series is a heavy-duty, large-capacity haulage truck specifi cally
  designed for the open pit mining industry. The large payloads that can be carried
  make this an effi cient means of transporting material from one point to another in
  a mine or similar off-highway haulage operation.
• Propulsion for the truck is supplied by a “diesel-electric” power train. The
  operating principal is to supply a regulated source of voltage and current to
  the wheelmotors, which convert this energy into a mechanical form through a
  self contained traction motor and planetary gear drive system which is directly
  mounted to the rear dual tire assemblies.
• In the “diesel-electric” mode, an alternator, directly coupled to a turbo-charged
  diesel engine, supplies the basic electrical energy. A primarily solid state control
  system regulates the power output based on a number of operating factors
  (including such items as vehicle and engine speed, demand requirements, and
  engine power available).
• In normal operation, the truck’s speed on downgrades and slowing for normal
  stopping is controlled by an electrical dynamic retarding system. When this
  system is activated, the wheelmotors function as generators and convert truck’s
  kinetic energy (force keeping the truck moving) into electrical energy. This
  electrical energy is dissipated as heat through a series of air-cooled resistors.
• For further explanation of the dynamic retarding system, refer to Section 6 –
  Operation of this manual.
