Heavy Duty Double Girder Overhead Crane Double Trolley 60t 80t QE
Product Description
Double Trolley Bridge Double Girder Crane adopts bridge structure with two trolleys and two main girders. It mainly consists of several components such as motor, reducer, brake, sensor, control system, lifting mechanism and trolley brake. These components work together to enable the crane to realise horizontal and vertical movement and lifting and unloading tasks.
Working principle
The working principle of double trolley overhead double girder crane is as follows:
1. The driving motor drives the main girder through the reducer. The main girder is equipped with one or more lifting mechanisms, which can be moved in the direction of the main girder and the direction of the trolley. The lifting mechanism usually consists of wire ropes, sheave sets, hooks and clamps, etc., which can be easily replaced or adjusted according to demand.
2. The trolley also has an electric motor and brake to enable it to run smoothly on the trolley tracks above and below the main beam, providing movement in the horizontal direction. The electric motor on the trolley moves the trolley wheels through a reduction gear to enable lateral movement of the load.
3. During the lifting process, the crane operator uses the control system to precisely manoeuvre the motor and brake so that the lifting mechanism grips the load securely and lifts it. The trolley then works in conjunction with the main beam to move the load from one position to another with precision and accuracy, thus completing the loading and unloading work efficiently.
4. Sensors monitor the crane's operating status and load condition in real time to ensure safe operation.
Main Features:
1. Dual trolley design: able to handle multiple tasks at the same time, significantly improving work efficiency. When two objects with different positions or sizes need to be lifted at the same time, two trolleys can be used to operate separately, saving time and space.
2. High-precision positioning: when it is necessary to accurately position a long object, two trolleys can be used to operate together, which improves positioning accuracy and safety.
3. Large carrying capacity: the double girder structure makes the crane have a larger carrying capacity, suitable for lifting heavy objects.
4. Good stability: the bridge structure firmly supports the lifting mechanism, ensuring the stability of the crane during operation.
Safe system
1. Operators need to be professionally trained and hold appropriate certificates to ensure safe operation.
2. In the course of operation, operating procedures and safety norms should be strictly observed to avoid accidents.
3. Regular maintenance and repair of the crane to ensure that it is in good working condition.
