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 (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
1 Remove the retaining fasteners securing the
platform assembly to the platform rotator.
Remove the platform assembly and set aside.
Crushing hazard. The platform
assembly may become
unbalanced and fall if it is not
properly supported.
2 Tag, disconnect and plug the hydraulic hoses
from the platform rotator manifold. Cap the
fittings on the manifold.
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.
3 Support the jib boom leveling arms with an
overhead supporting device. Do not apply any
lifting pressure.
Bodily injury hazard. The jib
boom leveling arms may fall if
not properly supported.

lifting device. Do not apply any lifting
pressure.

rotator could fall when removed
from the machine if not properly
supported.
