Hoist Limit Switch
A couple of hoist troubles are caused by a hoist limit switch:
- Hook does not respond to the control station or control device.
- Hook lowers but does not raise.
- Hook raises but does not lower.
- Hook fails to stop at either or both ends of travel.
- Hook stopping point varies.
It is always recommended to refer to CM hoist replacement parts user manual - Classic Lodestar for resolving the issues.
Caution: DO NOT use limit switches as routine operating stops. They are emergency devices only
Extended Limit Switch Parts
To replace the stock limit switch shaft with a 56 TPI shaft, you will need a 56 TPI Limit Switch Shaft, a Limit Switch Shaft Gear and a 56 TPI Limit Switch Nut. This allows a maximum lift of 133 feet for Model B & F hoists and 262 feet for Model C hoists.
A 64 TPI Limit Switch Shaft is also available and requires a Gear and 56 TPI Nut to complete the assembly. This assembly increases the maximum lift of Model B & F hoists to 152 feet, and allows Model C hoists a maximum lift of 299 feet.
