Assembly
Refer to Dwg. MHP3219 on page 15. A. Heat Shrink Tubing; B. Dead End; C. Live End; D. Dead End.
1. Cut wire rope to desired length for drop, allowing for up to a foot (12 in.) extra, to wrap around the thimble.
2. Install hook (1) in seat of thimble (2).
3. Install heat shrink tubing (5) on to dead end of wire rope, ensure shrink tubing is pushed up far enough to allow wrap around thimble and
addition of clamp. 4. Wrap wire rope around thimble (2). Wire rope should be securely seated in groove.
5. Place both halves of clamp around wire rope and loosely secure with first capscrew, but do not tighten. Ensure wire rope is secure between
both halves and a minimum of 1 in. of extra wire rope at dead end is extended past clamp.
6. Take up slack of wire rope around the thimble. Ensure wire rope is seated in center of clamp.
7. Install second capscrew and alternately tighten capscrews, torque to 7 ft. lb.
● When assembled both halves of clamp should not meet when torqued to the proper value. Clamp is designed for a wire rope
diameter of 5 mm.
● If both halves are flush against each other a smaller size of clamp is necessary.
8. Secure dead end of wire rope with electrical tape to keep it from fraying.
9. Slide heat shrink tubing, over dead end of wire rope, ensure it seats close to clamp.
10. Apply heat (140 degree C maximum) evenly around the shrink tubing until tube is takes form of the wire rope end. Allow the shrink wrap to
cool and harden.
Do not use a torch or any flame to shrink tubing. Use of a torch or flame could cause damage to the live end of wire rope.
11. Capscrews must be retightened again:
- 1 hour after installation.
- 2 times during first 24 hours, at reasonable breaks.
- Approximately 1 month after installation.
Note: Hook shown is the spring lock. Refer to Product Parts Information Manual for other hook options.
Load Blocks
Load Block Installation
Refer to Dwg. MHP1363 on page 15, A. Load Block, Single Sheave Cable; and MHP1364 on page 15, A. Load Block, Double Sheave Cable;

2. Bring excess wire rope back up to bottom eye pad of balancer.
3. Install thimble on eye pad.
4. Loop wire rope around thimble.
5. Tighten wire rope and install clamps.
Balancers using load blocks should not have ball stops on wire rope.
Preventive Maintenance Checks And Service
Clean, dry air must be used at all times when operating balancers.

Preventive Maintenance

Preventive maintenance recommendations are designed to prevent unexpected breakdowns and problems through periodic inspection and
maintenance. Maintenance intervals should be based on frequency of usage and operating environment. Frequent usage, or dirty operating
conditions require more frequent servicing. A clean, dry air supply will help keep the equipment functioning properly. Refer to "INSPECTION
AND MAINTENANCE REPORT" on page 12. Using this report will aid in tracking component failures or faults. We recommend the use of this
report as a preventive maintenance tool.
Wire Rope and Load Hooks
Wire rope, load hooks and clamps should be inspected on a daily basis. Time intervals should be based on the frequency of usage and in
accordance with standard wire rope manufacturers specifications. Refer to "PREVENTIVE MAINTENANCE SCHEDULE" on page 11.
Wire Rope Inspection
1. Depress the down lever to lower the load to the bottom of balancer travel.
