  • Control unit for controlling a hoist in a load slip condition and method thereof
    Patent number: 10988356
    Abstract: The present disclosure relates to a control unit for controlling operation of a hoist in a load slip condition. The hoist may include a motor coupled to a winding drum for lifting and lowering a load. The control unit may include a processor and a memory communicatively coupled to the processor. The memory may store processor executable instructions, which, on execution, cause the processor to operate the hoist for selectively lifting and lowering a load between a first position and a second position upon detecting a load slip condition. The processor may operate the hoist based on parameters pertaining to transport of the load. The control unit may be configured to reciprocate the load in a load slip condition to prevent overheating and failure of a motor, thereby preventing a fall of the load in a work area.
