Bridge crane with grab

This kind of overhead crane is mainly composed of box bridge, grab trolley, crane operation mechanism, driver's cab and electrical control system.The grab trolley is arranged with a lifting mechanism and an opening and closing mechanism, and the grab is respectively wound on the lifting and opening and closing drums with four wire ropes. The opening and closing mechanism drives the grab to close and grab materials. When the bucket mouth is closed, the lifting mechanism is started immediately to make the four steel wire ropes evenly loaded for lifting. When unloading, only the opening and closing mechanism is started, and then the bucket mouth is opened to dump materials. Except for the lifting mechanism, the other parts of the crane are basically the same as the hook bridge crane.
