什么是双小车桥式起重机？其工作原理是什么？

The double trolley overhead crane is composed of multiple components such as motors, reducers, brakes, sensors, control systems, lifting mechanisms, and trolley brakes. Its main feature is to support and operate the lifting mechanism through a bridge structure, with two trolleys and two main beams. These components work together to enable the crane to move and lift horizontally and vertically.

The working principle of the double trolley bridge crane is as follows: First, the drive motor drives the main beam to run through the reducer. One or more lifting mechanisms are installed on the main beam, which can move along the direction of the main beam and the direction of the trolley. The lifting mechanism usually consists of wire ropes, pulleys, hooks and clamps, etc., which can be replaced or adjusted as needed. Next, there is also a motor and brake on the trolley, which can run along the trolley tracks above and below the main beam and provide horizontal movement. The motor on the trolley drives the trolley wheels through the reducer to realize the lateral movement of the goods.

在起升过程中，起重机操作员通过控制系统控制电动机和制动器，使起升机构抓取货物并将其举升。然后，小车和主梁一起移动，将货物从一个位置移动到另一个位置，最终完成装卸任务。传感器监测起重机的运行状态和负载情况，确保安全运行。

Twin trolley axle cranes offer several advantages. First of all, due to the bridge structure, it can cover a larger working range and is suitable for large-scale lifting tasks. Secondly, the double trolley design allows the crane to perform multiple tasks at the same time, improving work efficiency. In addition, the flexibility of independent operation of the twin trolleys allows the crane to cope with complex working scenarios and requirements.

双小车起重机广泛应用于各个工业领域。它们通常出现在港口、码头、制造、仓储和物流等行业。在港口和码头，双小车起重机用于装卸集装箱和重型货物。在制造业，它们用于移动和安装大型机械和设备。在仓储和物流领域，双小车起重机用于高效搬运和储存货物。

In short, the double trolley 桥式起重机 is a powerful lifting equipment that achieves flexible and efficient heavy object lifting and unloading operations through the design of the bridge structure, double trolleys and double main beams. Their working principle is simple and straightforward, but operation and control require professional skills and experience. In various industrial fields, double trolley overhead cranes play an important role, improving work efficiency and promoting industrial development.
