Platform Rotator

The platform rotator is a hydraulically activated
helical gear assembly used to rotate the platform
160 degrees.
How to Remove the
Platform Rotator
Component damage hazard. Mark
the platform mounting weldment
and the rotator flange before
removing the platform mounting
weldment. The platform mounting
weldment must be replaced in the
exact same position on the rotator
flange as it was before removal. If
a new rotator is installed or the
rotator is disassembled, proper
alignment can be achieved by
rotating the rotator all the way to
the left and then installing the
platform mounting weldment all
the way in the left position.
Note: When removing a hose assembly or fitting,
the O-ring on the fitting and/or hose end must be
replaced and then torqued to specification during
installation. Refer to Section Two, Hydraulic Hose
and Fitting Torque Specifications.
1 Remove the platform and platform support.

PLATFORM COMPONENTS
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to squirt
or spray.

mounting weldment could become
unbalanced and fall if it is not
properly supported.
