CARRIAGE
Figure 1. Safety Chain the Mast
Description
The reach carriages are used to extend the forks of
the carriage. There are two types of reach car-
riages. There is a single-reach carriage with one set
of scissor arms. The other carriage has two sets of
scissor arms for double reach. See Figure 2. Both
carriages have a tilt cylinder to tilt the forks. Each
carriage is available with sideshift function. Refer
to Figure 9 and Figure 10. The rear and front frame
assemblies are connected by a scissor linkage. The
top of the scissor arm weldment is fastened to the
top of the rear frame by pins located within the
rear frame assembly. The top of each scissor arm at
the front frame is fastened by pins located at the
top of the front frame assembly. On double reach
units, the ends of each set of scissor arms and scis-
sor arm weldments are fastened together by studs
with bushings. The bushings permit the arms to
pivot. Large bearings at the center pivot of each
scissor arm assembly also permit the linkage to
pivot. Refer to Figure 11 and Figure 15.
NOTE:
The reach assembly can be removed from
the mast assembly with the load backrest and forks
attached. The three-stage mast assemblies can also
be removed with the reach assembly installed. Per-
form only those procedures necessary for repair.
