Grab overhead crane

The grab overhead crane is mainly composed of box bridge frame, grab trolley, trolley driving mechanism, driver's cabin and electrical control system. The lifting device is a grab bucket. The grab trolley is equipped with a lifting mechanism, as well as an opening and closing mechanism. The grab is wrapped around the lifting and opening and closing drums with four cables respectively. The opening and closing mechanism causes the grab bucket to close and grab the material. When the bucket mouth is closed, the lifting mechanism is immediately started so that the four steel cables are evenly loaded for lifting work. When unloading, only the opening and closing mechanism is activated, and the bucket mouth opens immediately to tilt the material. Except for the different lifting mechanism, the rest of the structure of this crane is basically the same as the hook overhead crane.
