Position the "ROPE GRIPPER
•
from top to bottom. Make sure the gripper is squarely aligned, and centered side to side as
much as possible, with the ropes. Misalignment may cause uneven and/or excessive lining
wear. Note:
o In some cases, rope orientation may twist through the hoistway, such as when the
overhead and car sheaves are not aligned. In this case, some "misalignment" to
the stationary pad is necessary. This is acceptable so long as the ropes clear both
pads while traveling.
o Rope splay near the hitch may cause additional alignment challenges. In these
cases, rope clamps such as H-W's Rope Guide (P/N 270-109) may be utilized.
•
Securely fasten the gripper mounting bolts (5 bolts per side). Torque to specifications in
Chart 1 above. * Note: The 6 5/8" bolts supplied with the 626 and 626-SPL Grippers
ONLY securing the mounting angles (3 per side) to the Gripper are Grade 8 and should be
tightened to 225 ft-lbs.
•
Double check rope alignment. Notes above notwithstanding, the ropes should touch the
stationary shoe lining evenly if applicable.
•
Reinstall movable shoe assembly.
•
Reinstall connecting arms with chamfered edges facing inside the gripper and secure the four
snap rings.
•
Mount pumping unit in the best available location. Unit must be upright but can be placed on
either side of the gripper. See hose length notes on Page 4.
•
If necessary, wiring on the gripper can be rerouted to opposite side of assembly by relocating
the box connector to the opposite side and pulling wire through.
•
Remove the pumping unit knock-out for the hydraulic line, install the supplied Rubber
Grommet and route male hydraulic fitting through knockout hole on the side of pumping
unit. Inside pumping unit push male Quick-Connect fitting into female fitting while lifting
