Waste Handling Grab Overhead Crane is a kind of heavy lifting equipment specially used in waste transfer stations, incineration plants, landfills, recycling centers, etc. It is mainly used for gripping, handling, stacking, and sorting all kinds of solid wastes, such as domestic wastes, industrial wastes and construction wastes.

Clamshell Grab Bucket for Bridge Crane
The Grab Overhead Crane is an overhead crane designed for bulk material handling. Its core function is to grab, lift, transport and discharge materials by means of an electrically or mechanically driven Grab Bucket. Its working principle can be divided into the following key links:
A Grab Overhead Crane mainly consists of a bridge frame, an electric trolley, electrical equipment, and a grab, etc. The bridge frame provides a stable support structure for the whole bridge crane. It carries the weight of each component and the load during lifting.
Bridge Girder: spanning the working area, the trolley runs horizontally along the track.
Lifting trolley: the trolley runs along the bridge and moves horizontally, equipped with a lifting mechanism and an opening and closing mechanism.
Grab Bucket: Usually double or multi-valve clamshell structure, opening and closing is controlled by wire rope or chain, suitable for bulk materials such as coal, ore, grain, etc.
Grabbing materials: The grab unfolds and descends to the material pile through the opening and closing mechanism, and relies on its own weight or hydraulic/electrical drive to clamp the materials when it is closed.
Lifting and Transportation: The lifting mechanism lifts the fully loaded grapple to the required height, and the large and small vehicles work together to transport the material horizontally to the target position.
Unloading: The grab opens again at the unloading point to release the material and complete the cycle.
Grab bridge cranes can choose different types of grabs according to the material characteristics, such as light grabs (grain), medium grabs (coal), heavy grabs (ore), and special grabs (garbage, scrap steel, etc.). Common grab buckets are of the following two types:
Multi-Flap Orange Peel Grab Bucket
Clamshell Grab Bucket for Bridge Crane
Structural features: composed of two symmetrical jaw flaps, similar to the “clamshell”, through the wire rope or hydraulic cylinder control, opening and closing.
Applicable materials: coal, ore, gravel, grain, and other bulk materials with good fluidity.
Advantages: simple structure, easy maintenance, and even gripping force.
Structural features: composed of 4~6 curved jaw flaps, similar to “orange peel”, forming a confined space when closed.
Applicable materials: steel scrap, garbage, irregular lump materials (such as metal scrap, construction waste).
Advantage: wide gripping range, adaptable to complex-shaped materials, and good leakage prevention.
Grab bucket overhead cranes are widely used in all kinds of bulk material handling industry, which has high efficient loading and unloading capacity, and is the key equipment in the fields of harbor, electric power, metallurgy, building materials, chemical industry, grain, and garbage disposal. Due to the different characteristics of materials handled in each industry, it is necessary to match the corresponding type of grab to ensure operational efficiency and safety.
