Product Description
Clamshell Grab Bucket (Two-Jaw Grab Bucket)
Structural: Composed of two complete buckets forming a clamshell shape when closed
Working Principle: Operated by hydraulic cylinders or wire ropes to open/close the jaws
Application: Mainly used in ports, docks, railway stations, mining sites
Suitable Materials: Coal, sand, grain and other loose granular materials
Advantage: Simple structure, tight closure, strong grabbing force
Disadvantage: Weak digging force, not suitable for hard ground surfaces
Multi-Jaw Grab Bucket
Structural: Composed of three or more jaw plates
Working Principle: Each jaw segment driven by independent hydraulic cylinders to prevent leakage
Application: Scrap steel handling in steel mills, waste treatment plants, construction sites
Suitable Materials: Scrap metal, construction waste and other irregular materials
Advantage: Petal-shaped design with excellent anti-leakage performance
Disadvantage: Heavy self-weight and higher energy consumption
