2. Use a gloved hand to carefully slide up the rope, if the glove snags on the wire rope refer to "PREVENTIVE MAINTENANCE SCHEDULE" on page 11.
3. Check entire length of rope up to the wire rope guide.
4. Replace wire rope if found faulty.
Load Hook Inspection
1. Top bail of hook swivels freely.
2. Tip of hook aligns with the self-closing gate.
3. No more than 10% wear is allowed at the base of the hook.
4. No more than 5% wear in all other areas.
5. Quic-Check® marks must align with a half-inch increment.
Balancer Lubrication
Basic Balancer
There are only three moving parts (ball nut, thrust bearing and piston) inside the balancer that require periodic cleaning and lubrication. Cleaning
usually requires complete disassembly of the balancer and a thorough washing in a solution, such as mineral spirits.
Special lubricants mentioned in the reassembly instructions are recommended for balancers and are available through Ingersoll Rand.
Lubrication can be accomplished by partial disassembly of balancer while still on the overhead rail as follows:
1. On series EA and BA balancers, turn pilot regulator screw (counterclockwise) until wire rope is slack. On series ZA balancers, depress down
lever until wire rope is slack.
2. Remove load from balancer.
3. Turn off air supply.
4. Remove wire rope guide, end cap and piston. Refer to section Balancer Rebuild Disassembly steps 4 - 7 in Maintenance Information Manual
for removal of end cap.
5. Using a paint brush (or a similar object) reach through the wire rope window in the housing and apply approximately a tablespoon of
lubricant (10886) to ball screw.
Lubricant (10885) must be used in 500 lb. (227 kg) Balancer.
6. Using a clean rag, wipe off piston, cylinder bore of housing and ball screw cap.
7. Apply lubricant (10885) to cylinder bore and outside diameter of ball screw cap. To reassemble refer to section Balancer Rebuild Assembly
steps 6 - 14 in Maintenance Information Manual.
8. Attach control package to end cap. Turn on air.
9. Readjust balancer, per Control Operational Adjustments.
Air Supply
Be sure that air supply is free of rust, dirt, water and oil. Use of a good air filter and in-line regulator is highly recommended. 100 psi (6.9 bar) is
required to operate balancer at its maximum capacity. Lower pressure reduces balancer capacity accordingly. Do not use an air in-line oiler. Oil
will damage balancer and controls.
Balancers Not in Regular Use
1. Balancers which have been idle for a period of one month or more, but less than one year, should be given an inspection conforming with
the requirements of "Preventive Maintenance" prior to being placed into service.
2. Balancers which have been idle for a period of more than one year should be given an inspection conforming with the requirements of
"Periodic Inspection" prior to being placed into service.
3. Standby balancers should be inspected at least semiannually in accordance with the requirements of "Preventive Maintenance". In abnormal
operating conditions balancers should be inspected at shorter intervals.
