Platform Rotator
THIS PROCESS REQUIRES SPECIFIC REPAIR SKILLS AND
EXPERIENCE, APPROPRIATE LIFTING EQUIPMENT AND A PROPER
WORKPLACE����� DEATH, SERIOUS INJURY OR SIGNIFICANT MACHINE
DAMAGE COULD OCCUR IF YOU ATTEMPT THIS PROCESS WITHOUT
THE APPROPRIATE SKILLS AND EQUIPMENT�����
The Platform Rotator is located between the Platform and the Jib.
The Platform Rotator is normally removed only for repair or replacement.
This procedure differs from the Platform Removal procedure in that the platform is removed while still
attached to the Platform Rotator. This reduces the possibility of injury when the jib pivot points are
released.
A fork lift and pallet are needed for this procedure.
Disassembly
Park the machine on a firm level surface.
Throughout this procedure, thoroughly clean all hydraulic
connections and tag all hoses for proper reassembly
before disconnecting them. Immediately plug and cap
all openings to prevent contamination. Tag electrical
connections before disconnecting them.
Position the platform on a pallet so that the bottom of the
through bolt is off the ground. Strap the platform to the
pallet.
Disconnect the wiring harness from the Upper Controls
box. Carefully pull the wiring harness back to the jib.
Disconnect all hydraulic hoses. Immediately plug and
cap all openings to prevent contamination.
Remove bolt, pin retainer, lower pin and roller from the
Platform Rotator lower pivot point. Swing the lower jib
links out of the way.
Remove bolt, pin retainer and upper pin from the
Platform Rotator upper pivot point.
Use a forklift to move the platform away from the
machine.
Support the Platform Rotator. Remove the center
through bolt.
Remove the six button head bolts that secure the
platform mount weldment to the platform rotator. The
Platform Rotator is now detached from the platform.
