Wheel Motors (if self-propelled) – Electric or hydraulic drive systems.

Steering Mechanism – For directional control in mobile units.

5. Safety Features

Overload Protection – Prevents lifting beyond capacity.

Anti-Tip System – Ensures stability during movement.

Locking Pins/Brakes – Secures the hoist in position when stationary.

Emergency Manual Lowering – Backup in case of power failure.

 

6. Optional Add-Ons

Remote Control – Wireless operation for convenience.
