Arbetsprincipen för gripbrokranen

The grab bridge crane is a widely used equipment for loading and unloading bulk materials. It mainly relies on grab buckets for operation. Its working principle includes the following aspects:

The grab bucket bridge crane consists of a bridge frame, a lifting trolley, a grab bucket, and a drive system. The bridge spans over the work area, and the crane trolley moves laterally along the main beam track on the bridge. The grab bucket is connected to the lifting trolley through a steel wire rope or chain, and can be lifted up and down. The drive system includes components such as electric motors and reducers, which are responsible for driving the movement of the crane trolley and grab bucket.

The operator starts the crane through the control system and first moves the lifting trolley above the target position. Then, the grab bucket descends through the winch system, opens the grab bucket, and descends above the material. When the grab bucket is completely lowered onto the material pile, the hydraulic or electric system controls the grab bucket to close and grab the material. This process usually requires precise control to ensure that the grab bucket can firmly grasp the material.

After the grabbing is completed, the lifting trolley and grab bucket lift the material through the control system. The crane trolley moves along the main beam track to transport the grasped materials to the predetermined unloading position. At this point, the grab bucket descends again, opens the grab bucket. And places the material into the designated location, such as a transport vehicle, warehouse, or other storage area.

The entire operation process of the grab bridge crane is highly automated. The operator can perform precise control through the control panel or remote control. To ensure safe and efficient operation, the crane is equipped with various safety devices. Such as limit switches, overload protection devices, and emergency stop systems. These devices ensure that the crane can stop in a timely manner in case of abnormal situations. To prevent accidents and equipment damage.

By coordinating the work of the bridge frame, crane trolley, grab bucket, and drive system, the grab bucket bridge crane can efficiently complete the handling and loading/unloading tasks of bulk materials. Its flexible operation mode and powerful grasping ability make it an indispensable and important equipment in industries. Such as ports, docks, mines, metallurgy, and waste disposal.
