Production Description
Excavator Clamshell Bucket which fits to an excavator has powerful digging characteristics. Ideal for earth moving, ground works and road construction we have a range of shells available for different applications. The Clamshell bucket is driven by hydraulic cylinder to open and close, easy operation and good control of the strong digging force, especially good for limited working space.
Advantages
1. There are two types of Clamshell bucket: 360-degree rotating type & non-rotating type.
2. Adopts high quality meterial Q355B and NM360
3. Driven by double cylinder synchronously.
4. Bucket volume size from 0.2 to 5.0CBM
5. Connecting part adopts direction activity joints, easy adjustment
6. Flexible design, easy installation, improve the work efficienc
