A couple of hoist troubles are caused by a hoist limit switch:
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
The parts listed above are for a standard 44 thread per inch limit switch shaft. The limit switch assembly can be modified with a 56 thread per inch shaft or a 64 thread per inch shaft to increase the maximum lift. The chart below shows the maximum lift of different models with each type of limit switch shaft assembly:
|MODEL||44 TPI SHAFT MAX LIFT||56 TPI SHAFT MAX LIFT||64 TPI SHAFT MAX LIFT|
|L & J||127'||162'||185'|
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. A 64 TPI Limit Switch Shaft is also available and requires a Gear and 64 TPI Nut to complete the assembly.
