Introduction of Grab Bucket Overhead Crane
Basic Information Of Grab Bucket Overhead Crane
Grab bridge cranes are widely used in power plants, freight yards, workshops, docks, etc., for loading and unloading of bulk materials. The cranes are heavy-duty working systems, and the working level is A6. All mechanisms are operated in the cab. The directions for entering the platform door of the driver's cab are: end entry, side entry, and top entry. The rated lifting capacity includes the grab bucket's own weight. There are two types of grab opening directions: parallel and vertical to the main beam. The pick-up device is a four-rope grab bucket with two drums, which has a simple structure and reliable operation. The grab can be opened and closed at any height. Grab buckets are only suitable for bulk materials in a natural accumulation state. When grabbing underwater materials or special materials, it must be specified when ordering. The crane can be used indoors or outdoors, and a rain cover device is added for outdoor use.
Structure And Working Principle Of Grab Bucket Overhead Crane
The grab bridge crane is mainly composed of box-shaped bridge frame, grab trolley, cart running mechanism, driver's cab and electrical control system. The fetching device is a grab bucket capable of grabbing bulk materials. The grab bridge crane has an opening and closing mechanism and a lifting mechanism, and the grab is suspended on the opening and closing mechanism and the lifting mechanism by four steel wire ropes. The opening and closing mechanism drives the grab bucket to close to grab materials. When the bucket mouth is closed, the hoisting mechanism is activated immediately so that the four steel wire ropes are evenly loaded for lifting work. When unloading, only the opening and closing mechanism is activated, and the mouth of the bucket opens immediately to tilt the material. Except for the different lifting mechanism, the grab bridge crane is basically the same as the hook bridge crane.
