About Clamshell Bucket
 
The clamshell bucket opens downward and has a large capacity, which allows a large amount of material to be loaded.
It consists of three parts: the main connecting frame, the bucket flaps, and the hydraulic cylinder.
The excavator provides power, pressure, and flow to drive the hydraulic cylinder.
The opening and closing reciprocating motion of the bucket is achieved through the extension and retraction of the hydraulic cylinder. Therefore, the structure of the bucket is very simple.
 

 
Advantages of Clamshell bucket
 
1.Simple design, more stable and lighter
2.Grease can be added to ensure flexible operation
3.Double cylinder design reduce failure.
4.Arc-shaped design enchance loading and unloading efficiency
5.Teeth base is made of wear-resistant material, which longer service life

 
Customization
We offer custom clamshell buckets. You may select rotating or non‑rotating versions, choose your preferred paint colour, and decide whether to fit teeth. Both single‑cylinder and double‑cylinder designs are available. We can also adjust the bucket volume and opening size to suit your working conditions.
 

 
Two types of clamshell bucket
 

 

ZHONGHE triple quality control system
1.The first system is the technical design drawing review mechanism.
2.The second system is the semi-finished product review mechanism.
(each process has a detection testing for the previous process)
3.The third system is the finished product testing.
(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether the installation size meets the design requirement.)
To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.
