Uvod

A single girder bridge crane is a versatile and widely used material handling system in various industrial settings. It is designed to lift and transport heavy loads efficiently. Understanding its structural components is crucial for its operation and maintenance.

Main Girder

The main girder is the primary horizontal beam that spans the width of the crane's working area. It supports the weight of the load and the crane's hoist. Typically made of steel, the main girder must be robust and capable of withstanding significant stress and strain.

End Trucks

End trucks are positioned at both ends of the main girder. They contain the wheels or rollers that allow the crane to move along the runway beams. The end trucks ensure smooth and stable movement of the crane, providing the necessary mobility across the workspace.

Runway Beams

Runway beams are long, horizontal beams that run parallel to each other along the length of the facility. They support the entire crane structure, allowing it to travel the length of the workspace. These beams are mounted on columns or building structures and must be precisely aligned for safe and efficient operation.

Dvigalo

The hoist is the lifting mechanism of the crane. It moves along the main girder and is responsible for raising and lowering the load. The hoist can be electric or manual, depending on the application. It typically consists of a motor, drum, wire rope or chain, and a hook.

Trolley

The trolley carries the hoist and moves along the main girder. It allows for precise positioning of the load within the crane's working area. The trolley's movement, combined with the hoist's lifting action, provides full coverage of the workspace.

Control System

The control system includes the operator's controls, electrical wiring, and safety devices. It allows the operator to control the movement of the crane, hoist, and trolley. Safety features such as limit switches and emergency stop buttons are crucial for preventing accidents and ensuring safe operation.
