DESCRIPTION
This section describes the frames for the MPC060-
VG, MPC080-VG, MTR005-F, and MTR007-F trucks.
Repair procedures for major systems/parts that fasten
to the frame are found in separate YRM sections.
MPC060-VG and MPC080-VG trucks have a main
frame weldment and a fork frame weldment. The main
frame weldment has mounts for the master drive unit
(MDU), the lift pump and motor assembly, and
electrical system components. The mounting holes for
the casters are in the main frame weldment. The fork
frame weldment is fastened to the main frame
weldment by the links of the lifting mechanism. The
fork frame weldment is raised by a lift cylinder
connected to the main frame weldment and fork frame
weldment. The lift cylinder raises the battery end of
the fork frame weldment and the linkage mechanism
moves the load wheels to raise the fork tips at the
rear of the fork frame weldment. See Figure 1.
MTR005-F and MTR007-F trucks have a single-frame
weldment composed of the operator's compartment,
battery compartment, and master drive unit (MDU)
compartment. The frame weldment has mounts for
the MDU and electrical system components. See
Figure 2.
Most truck repairs are performed on the individual
components that are bolted to the frame weldment
and not to the frame weldment itself.
