Safety Retraction System Adjustments and Resetting
• Ingersoll-Rand units with capacities of 68 kg (150 lbs) or
greater are equipped with the Safety Retraction System, a
centrifugal brake that is designed to stop the uncontrolled
upward travel of the chain or wire rope in the event of a
sudden release or loss of load, and limit the excessive upward
acceleration of the empty hook for the safety of the operators.
The brake should in no instances be used as a travel limiting
stop or up stop. Failure to follow these instructions will result
in damage to the brake and the unit. Continuous use of the
brake will cause internal damage to the unit and could result
in damaging the unit beyond repair.
• Ingersoll-Rand installs the spring in hole #2 on the 91
kg (200 lb.), 158 kg (350 lb.), and 227 kg (500 lb.) units
and in hole #1 on the 68 kg (150 lb.) unit. To reduce
the sensitivity on the 91 kg (200 lb.), 158 kg (350 lb.),
and 227 kg (500 lb.) unit place spring in hole #3, 4 or
5. To reduce the sensitivity on the 68 kg (150 lb.) unit
place spring in hole #2 or 3.
• If the brake interferes with the operation of the
system in the hole farthest from the center, a heavier
spring is available through Ingersoll-Rand.
Safety Retraction System Reset Procedure
P Controls
1. Ensure the vertical path of the load is clear.
2. Press the down lever and release the air in the unit until the load begins to lower.
3. Resume operation.
4. If the brake engages when a load is attached or it interferes with standard operation, the brake must be
adjusted. Refer to Safety Retraction System Adjustments for further instructions.
S and E Controls
1. Ensure the vertical path of the load is clear.
2. Grasp the load hook at the lifting eye pad and pull down on
the chain or wire rope. Carefully and slowly release the load
hook.
3. Attempt to resume operation.
4. If the brake is still engaged. Rotate the pilot regulator screw
of the regulator until the load begins to lower. This will
change the settings on the control.
5. Follow the appropriate control adjustments to ensure the
proper operation of the unit.
6. Resume operation.
7. If the brake engages when a load is attached or if interferes
with standard operation the brake must be adjusted. Refer to
Safety Retraction System Adjustments for further instructions.
