Load Hook Installation and Yarding
Installation
To properly install the load hook to wire rope or chain
determine the following:
1. Highest point which load must clear from floor.
Refer to Dwg. MHP1358.
2. Distance from hook throat to bottom of load. Refer to
Dwg. MHP1359.
3. Add number 1 dimension to number 2 dimension,
then add 89 mm (3-1/2 in.).
4. Measuring from the floor with the wire rope or chain
fully retracted, install hook using the dimension from
instruction 3 to the floor.
• Do not operate the unit if load is not centered under
wire rope or chain. Yarding of the wire rope or chain
will cause premature wire rope or chain failure, undue
wear of internal unit parts and may void warranty.
Yarding
The chain or wire rope should not be yarded more than 10 degrees from the center
line of the chain/wire rope guide.
Excessive yarding will cause increased wear on the unit and decrease the working
life of the components.
Load Hooks
Chain To Hook Assembly
Insert chain in slot in plug (3). Insert chain and plug combination into chain hook
(2). With all parts together be sure that pin holes in the plug and hook are in line.
In addition, make sure that chain is positioned in slot with sufficient depth to
allow pin to pass through last link of chain. Press pin (4) into assembly to connect
chain to chain hook.
Wire Rope To Hook Assembly
Spread and insert thimble (2) to clamp loop. Thread wire rope around thimble.
• Allow at least 25 mm (1 in.) of excess wire rope. Join load end wire rope
strand to excess and install clamp as shown in Dwg. MHP1362.
• Units using load blocks should have ball stops on wire rope.
• Be sure chain is not twisted when routing around pulley in load block. The
chain welds should not run on the pulley.
Load Blocks
Load Block Installation (Wire Rope)
1. Thread wire rope through and around pulley(s) in load block.
2. Bring excess wire rope back up to bottom eye pad of unit.
3. Install thimble on eye pad.
4. Loop wire rope around thimble.
5. Tighten wire rope and install clamps.
