Components of Overhead Cranes

Bridge

• The bridge is the main component, consisting of the main beam, end beams, and a walking platform.
• The main beam is typically a box-shaped structure, and the end beams are connected at both ends of the main beam[5].

Lifting Mechanism

• The lifting mechanism includes a motor, reducer, drum, and brake.
• For cranes with a lifting capacity of 15 tons and above, there are often two sets of lifting mechanisms: the main hook and the auxiliary hook[5].

Crane Travelling Mechanism

• This mechanism allows the crane to move along the runway beams.
• It consists of a motor, transmission shaft, reducer, wheel, and brake, with centralized or separate driving modes[5].

Trolley Travelling Mechanism

• The trolley moves along the width of the workshop on the bridge rail.
• It includes a trolley frame, trolley running mechanism, and lifting mechanism. There are two transmission forms for the trolley running mechanism[5].

Control Room

• The control room houses the control devices for the crane and trolley movements, lifting mechanisms, and crane protection devices.
• The cab can be fixed at one end of the main beam or mounted below the trolley[5].

Design Features and Considerations

Steel Construction

• The bridge girder uses a welded plate box girder design and can be constructed to meet local codes and regulations[2].

Hoisting Mechanism

• The hoisting mechanism can be a standard wire rope electric hoist or an electric chain hoist, depending on the lifting requirements[2].

Crane Travelling Mechanism

Selecting the Right Crane

Rated Load Capacity

• Determine the maximum weight the crane needs to lift.

Span and Lifting Height

• Specify the distance the crane needs to span and the height it needs to lift loads[3].

Duty Cycle

• Consider how often the crane will be used, the number of lifts per hour, and the average rated load it will lift[2].

Control System

• Choose between pendant control, wireless remote control, or cabin control based on user preference, crane working environment, and load capacity[2].

Runway Requirements

• Determine if a runway is required and specify its length. Longer runways increase costs[2].

After-Sales Service and Maintenance

Installation and Commissioning
