CABLE HYDRAULIC INSTALLATION
1) Make sure the wedge clamps and the eye bolts have been placed in position on the
attachment provided near the bottom of the Upstand Post.
2) Identify the cables as they descend the other side of the sheave, and attach them to the
wedge clamps.
NOTE: ENSURE THAT THE CABLES DO NOT CROSS OVER. (See
Figure # 13). Manually thread the cables into the wedge in a loop, and place the loose
wedge piece in the loop. Pull on the loose end to take up the slack in the cable. Confirm
that each loaded cable is directly over the threaded rod. DO NOT REVERSE.
3) Pull up on both cables until they are equal in tension. The wedge piece will hold the
cables in place. Tape the loose ends of each cable temporarily to prevent them from
becoming wedged in the sling. They will be cut later.
NOTE
Before putting any weight on the cables, make sure that the nuts on the rope wedge threaded
rods are “backed off” to the end of the threads on the rod. To ensure plenty of adjustment to
equalize the cable tension when weight is applied, leave two full nuts at the end on the thread.
When adjusted, there must be two (2) nuts locked together on the underneath side of each
rod. There may also be one nut on top that is used to prevent the shackle from rotating.
4) Perform a final inspection to ensure that all cables are in correct alignment and that all
hardware such as bolts, clamps, wedges and pins are in place.
