What is a double trolley bridge crane?

Double trolley bridge crane is a common lifting equipment. Adopting a bridge structure with two small cars and two main beams. It is widely used in various industrial fields for indoor and outdoor heavy object lifting and unloading operations. This article will provide a detailed introduction to the definition, working principle, and industrial application of it.

The double trolley bridge crane consists of multiple components. Such as an electric motor, reducer, brake, sensor, control system, lifting mechanism, and trolley brake. Its main feature is to support and operate the lifting mechanism through a bridge structure. While having two hoist trolleys and two main beams. These components work together to enable the crane to move and unload tasks in both horizontal and vertical directions.

The working principle of a double trolley bridge crane is as follows. Firstly, the driving motor drives the main beam through a reducer. There is one or more lifting mechanisms installed on the main beam, which can move along the direction of the main beam and the direction of the trolley. The lifting mechanism is usually composed of steel wire ropes, pulleys, hooks, and clips, which can be replaced or adjusted as needed. Next, there is also an electric motor and brake on the car, which can run along the car tracks above and below the main beam, and provide horizontal movement function. The electric motor on the car drives the small wheels to move laterally through a reducer to achieve the movement of goods.

During the lifting process, the crane operator uses a control system to control the electric motor and brake. Allowing the lifting mechanism to grasp the cargo and lift it. Next, the trolley and the main beam work together to move the goods from one position to another. Ultimately completing the lifting and unloading task. Sensors can monitor the operating status and load conditions of cranes to ensure safe operation.

In short, the double trolley bridge crane is a powerful lifting equipment. Through the design of bridge structure, double trolley and double main beam, flexible and efficient heavy object lifting and unloading operations have been achieved. Their working principle is simple and clear, but operation and control require professional skills and experience. In various industrial fields, double trolley bridge cranes play an important role in improving work efficiency and promoting industrial development.
