How the crane works

A crane is a mechanical device for vertical lifting and horizontally handling of heavy objects. Its working principle is mainly based on electric drive, mechanical transmission and control systems. The following is a detailed analysis of the working principle of the crane: ‌

1. Electric drive and mechanical transmission

Electric end beam drive main beam: The main beam of the crane is the core part of the load-bearing heavy objects. Through the electric end beam drive system, the main beam can move horizontally along the track. The electric end beam drive system is usually composed of a three-in-one motor and a beam head. By controlling the operation of the motor, the precise movement of the main beam is achieved.

Electric hoist lifts weights‌: Cranes are usually equipped with electric hoists for lifting and hoisting cargo. The electric hoist drives the reel of the wire rope through a motor to realize the lifting and lowering of the goods. The electric hoist is also equipped with limit switches and heavy-load protection devices to ensure safety in the lifting process.

2. ‌Running tracks and horizontal movement

Cranes are usually installed on specific operating tracks through which they can be moved horizontally. This design allows the crane to efficiently carry heavy objects in a limited space.

3. Control system and motion control

The motion control of the crane is mainly achieved through the control system. The control system usually includes components such as electrical control boxes, control buttons, sensors and encoders. The operator controls the movement of the crane through control buttons, and the sensors and encoder monitor the position and movement status of the crane in real time to ensure the safety and accuracy of the lifting process.

4. Lifting, running, amplitude and rotation

‌Lifting‌: Lift the heavy object from the pickup location through the lifting mechanism to achieve vertical lifting.
‌Operation: Transport heavy objects horizontally to designated locations through the operating mechanism.
‌Amplitude‌: By changing the length and angle of the crane boom, lift items at a distance.
‌Rotation‌: The boom is transported around the crane through a rotating mechanism to achieve long-distance transportation of heavy objects.

5. Intermittent exercise and working cycle

The working characteristics of the crane are intermittent movement, that is, in a working cycle, the corresponding mechanisms for material collection, transportation, unloading, etc. work alternately. This working method allows the crane to efficiently complete material handling tasks.
Through the above working principle, cranes can efficiently and safely complete the lifting and handling tasks of heavy objects in various industrial scenarios.
