1.Main beam

1) The main beam of a double-beam gantry crane usually consists of two parallel main beams, which are connected by a gantry and support the trolley and lifting mechanism. The main structural features of the main beam include:

Main beam shape: The main beam is generally made of I-beam or box-shaped structure. The I-beam design makes the main beam light and has good load-bearing capacity, while the box-shaped structure provides higher rigidity and stability.

Span: The span of the main beam is usually designed according to actual use requirements and working environment. The span size will affect the overall stability and work efficiency of the crane.

Connectors: The main beam is fixed to the end beam and the gantry through connectors to ensure the overall stability of the structure.

2) Function

Carrying heavy objects: The main beam is the main component of the crane to carry heavy objects, and the load is transmitted to the structural foundation of the crane through the main beam.

Supporting trolley: The main beam provides a track for the movement of the trolley, allowing the trolley to move freely on the main beam to complete the lifting operation.

Stable structure: The cooperation between the main beam and the gantry ensures the overall stability of the crane and prevents the risk of tilting or collapse during operation.

Lifting System

The lifting system is usually composed of several key components, mainly including:

1) Motor:

Provides power for the lifting system, usually using asynchronous motors or servo motors, with high efficiency and reliability.

2) Reducer:

Connected between the motor and the drum, used to reduce the speed of the motor and increase the torque to meet the lifting needs of heavy objects.

3) Drum:

Used to wind the wire rope or chain for lifting, and realize the lifting and lowering of goods through the rotation of the drum.

4) Hook:

Connected to the end of the lifting wire rope or chain, used to directly hang and carry goods.

5) Lifting chain or wire rope:

The lifting chain or wire rope responsible for carrying the goods must have sufficient strength and wear resistance to ensure safety.

 

3.End carriage

The end beam is usually a crossbeam connected to both ends of the main beam of a double-beam gantry crane to form an integral frame structure. Its main structural features include:

Transverse connection: The end beam provides the necessary stability and rigidity for the crane by connecting the main beam transversely.

Supporting structure: The end beam supports the operating mechanism of the crane (such as the trolley operating mechanism) and ensures the balance of the entire system during operation.

Design shape: The end beam is usually constructed of I-beam or other steel sections, and the specific shape depends on the design requirements.

2) Material

The material selection of the end beam is also crucial. Commonly used materials include:
