Overhead Bridge Crane

Main Components

A overhead bridge crane consists of several essential components that work together to provide efficient lifting and movement:

• Main Girder: The horizontal beam that supports the hoisting trolley. This is available in both single and double girder designs to accommodate different load capacities.

• Supporting Legs: Vertical structures that provide stability to the crane, connecting the main girder to the ground rails or wheels for smooth operation.

• End Carriages / Wheels: Located at the bottom of the supporting legs, these parts enable the crane to travel along the rails or across the ground, facilitating easy movement.

• Hoisting Trolley: This unit moves along the girder and holds the hoist, allowing for precise lifting and lowering of heavy loads.

• Hoist: Typically a wire rope or chain hoist, it is responsible for performing the lifting function of the crane.

• Electrical System: Powers the entire crane, including control panels, motors, and wiring, ensuring smooth and efficient operation.

• Control Options: Offers flexibility in operation with options for pendant control, wireless remote control, or operator cabin, depending on the specific requirements of the task.
