5.4-18 Extension Cylinder and Wire Rope
Assembly Installation
1.
Attach two lifting slings to the extension cylinder.
Using suitable lifting equipment, raise and slide
the end slowly into the counterweight end of the
boom assembly. The upper wire ropes can be
tie-wrapped to the cylinder to keep them from
getting tangled. Be sure to remove the tie wraps
as the cylinder is being installed.
NOTE
Make sure the cables do not get tangled or
caught on other components.
2.
Orient the wire ropes correctly. Identify which
cable ends go to the platform end, and which go
to the counterweight end of the machine. The
tapered end of the wire rope terminal plate is
towards the platform end of the machine when
installed. The shorter length wire ropes anchor
at the platform end.
3.
Lift and slide the end of the cylinder into the
boom, being careful not to tangle the wire ropes.
4.
Once the pulley end of the cylinder is into the
boom, one lifting sling can be removed. Lower
the cylinder onto a suitable stand or support and
remove one sling. Connect the lifting sling to the
end of the cylinder.
5.
Carefully feed the wire ropes in as the cylinder is
being pushed in.
6.
Slide the cylinder 2/3 of the way in until the wire
rope terminal plate has passed where the mid
boom pulleys mount.
