What is a double trolley overhead crane? How does it work?

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.

리프팅 과정에서 크레인 운전자는 제어 시스템을 사용하여 모터와 브레이크를 제어하여 리프팅 메커니즘이 화물을 잡고 들어 올릴 수 있도록 합니다. 그런 다음 트롤리와 메인 빔이 함께 이동하여 상품을 한 위치에서 다른 위치로 이동하고 최종적으로 적재 및 하역 작업을 완료합니다. 센서는 크레인의 작동 상태와 부하 상태를 모니터링하여 안전한 작동을 보장합니다.

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.

더블 트롤리 오버헤드 크레인은 다양한 산업 분야에서 널리 사용됩니다. 이는 항만, 터미널, 제조, 창고 및 물류와 같은 산업에서 흔히 발견됩니다. 항구와 터미널에서는 컨테이너와 무거운 화물을 싣고 내리는 데 트윈 트롤리 오버헤드 크레인이 사용됩니다. 제조에서는 대형 기계 및 장비를 이동하고 설치하는 데 사용됩니다. 창고 및 물류 부문에서는 상품의 효율적인 취급 및 보관을 위해 트윈 트롤리 오버헤드 크레인이 사용됩니다.

In short, the double trolley 브리지 크레인 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.
