Supporting Legs: Vertical columns that provide structural support to the main girder, connecting to the ground rails or wheels for stable movement.
End Carriages / Wheels: Positioned at the bottom of the legs, these components allow the crane to travel along rails or across the ground surface with ease.
Hoisting Trolley: This unit moves along the girder and supports the hoist responsible for lifting and lowering heavy loads.
Hoist: Available in either wire rope or chain types, the hoist is the primary mechanism used for lifting and lowering the load.
Electrical System: Powers all crane operations, including the motors, control panels, and cabling, ensuring smooth and efficient functionality.
Control Options: Can include pendant controls, wireless remote controls, or operator cabins, depending on your specific operational preferences.
