How Double Girder Gantry Crane Works


Post time: Oct-16-2024

A double beam gantry crane works in coordination with several key components to lift, move and place heavy objects. Its operation mainly relies on the following steps and systems:

Operation of the trolley: The trolley is usually mounted on two main beams and is responsible for lifting heavy objects up and down. The trolley is equipped with an electric hoist or lifting device, which is driven by an electric motor and moves horizontally along the main beam. This process is controlled by the operator to ensure that the objects are lifted to the required position accurately. Factory gantry cranes can withstand larger loads and are suitable for heavy-duty operations.

Longitudinal movement of the gantry: The entire factory gantry crane is mounted on two legs, which are supported by wheels and can move along the ground track. Through the drive system, the gantry crane can move smoothly forward and backward on the track to cover a larger range of working areas.

Lifting mechanism: The lifting mechanism drives the wire rope or chain through an electric motor to lift and lower. The lifting device is installed on the trolley to control the lifting speed and height of the objects. The lifting force and speed are precisely adjusted by a frequency converter or similar control system to ensure stability and safety when lifting heavy objects.

Electrical control system: All movements of the 20 ton gantry crane are operated by an electrical control system, which usually includes two modes: remote control and cab. Modern cranes use PLC control systems to implement complex operating instructions through integrated circuit boards.

Safety devices: In order to ensure safe operation, the 20 ton gantry crane is equipped with a variety of safety devices. For example, limit switches can prevent the trolley or crane from exceeding the specified operating range, and devices to prevent equipment overload will automatically alarm or shut down when the lifting load exceeds the designed load range.

Through the synergy of these systems, the double beam gantry crane can efficiently complete various lifting tasks, especially in situations where heavy and large objects need to be moved.
