Parts of Overhead Crane

Overhead cranes, also known as bridge cranes, are widely used in various industries for material handling and lifting operations. They consist of parallel runways with a traveling bridge that spans the gap, and a hoist and trolley system that moves along the bridge to lift and transport loads. Overhead cranes are typically classified into two types: single girder and double girder.

Single Girder Overhead Crane: This type of overhead crane consists of a single bridge girder supported by two end trucks. The hoist and trolley system run along the lower flange of the bridge girder. Single girder overhead cranes are generally more economical and suitable for lighter loads and shorter spans.

Double Girder Overhead Crane: In a double girder overhead crane, two bridge girders are supported by the end trucks, and the hoist and trolley system runs on rails mounted on top of the girders. Double girder overhead cranes offer greater load capacity, longer spans, and increased hook height compared to single girder cranes. They are ideal for heavier loads and more demanding applications.

Key parts of an overhead crane include:

  1. Bridge Girders: These are the main horizontal beams that span the width of the crane and support the hoist and trolley system. In single girder cranes, there is one bridge girder, while double girder cranes have two.
  2. End Trucks: These are the wheeled structures located at each end of the bridge girders. They enable the crane to travel along the runway beams.
  3. Runway Beams: These are the parallel, elevated beams on which the end trucks travel. They support the entire crane system and are typically mounted on support columns or attached to the building structure.
  4. Hoist: The hoist is the lifting device that raises, lowers, and holds the load. It can be electric, manual, or pneumatic and consists of a motor, gearbox, drum, wire rope or chain, and hook.
  5. Trolley: The trolley is the component that carries the hoist and allows it to move along the bridge girder(s). It consists of a frame, wheels, and drive mechanism.
  6. Controls: Overhead cranes can be controlled using pendant controls, remote controls, or cabin controls. These systems allow the operator to manage the crane's movements, including lifting, lowering, and positioning loads.
  7. Electrification System: This consists of power supply components such as conductors, collectors, and cable festoons that provide electricity to the crane's motors and control systems.

Parts that are regularly serviced or replaced include:

  1. Wire ropes or chains: These components are subject to wear and tear and should be regularly inspected for signs of damage, such as broken strands, kinks, or excessive stretching.
  2. Hoist brakes and clutches: Regular maintenance of these components is crucial for ensuring safe and efficient operation of the crane.
  3. Wheels and bearings: These components should be inspected for signs of wear or damage and lubricated regularly to ensure smooth movement and reduce friction.
  4. Electrical components: Inspect and replace worn or damaged electrical components, such as contactors, switches, and cables, to ensure the crane's safe and efficient operation.
  5. Trolley and end truck wheels: Regularly inspect the wheels for wear or damage, and check the alignment and tracking of the crane to prevent premature wear.
  6. Lubrication: Regular lubrication of moving parts, such as gears, bearings, and sheaves, is essential for reducing friction, preventing wear, and ensuring smooth operation.

By regularly servicing and replacing these components, you can ensure the safe and efficient operation of your overhead crane, prolong its service life, and minimize.
