Supporting Legs: Vertical columns that uphold the main girder and connect securely to ground rails or wheels.
End Carriages / Wheels: Positioned at the base of the legs, enabling smooth crane movement along rails or the ground surface.
Hoisting Trolley: Travels along the main girder and carries the hoist for lifting and lowering loads.
Hoist: Available as a wire rope or chain hoist, responsible for executing the vertical lifting function.
Electrical System: Supplies power to all crane operations, including motors, wiring, and control panels.
Control Options: Offers operation via pendant control, wireless remote, or operator cabin, depending on specific needs.
