Mount the Operator Platforms and Install the
Foot Throttles
Install the operator’s platform on both sides of the frame as
shown in Figure 9-17. Assemble and mount the foot throttles
(Figure 9-17).
Mount the Electronic Engine Throttle (EET) control in the
frame (Figure 9-17). Route the harness through the access
holes in frame to the EET from the foot throttles.
Install the Boom, Lift Cylinder, and Hoist
Install the boom and lift cylinder as described in See “Boom
Maintenance” on page 4-1. Install the hoist as described in
SECTION 5. For hoist cable and wedge socket installation,
see SECTION 4 of the Operators Manual.
Install the RCL Reel
The crane is shipped with the RCL reel temporarily attached
to the top of the boom (Figure 9-19). To mount the reel:
1. Remove the RCL reel and mounting brackets from the
top of the boom (Figure 9-19).
2. Bolt the C-brackets to the bottom of the boom.
3. Attach the mounting brackets to the RCL reel and mount
the RCL to the boom as shown in Figure 9-20.
NOTE: The RCL must be mounted as shown to get the
proper clearance.
CAUTION
Make sure there is adequate clearance between the RCL
reel and adjacent components so that the RCL reel does
not come in contact with and damage the components
when the boom is fully lowered.
