Excavator Hydraulic Thumb Bucket
CTHB Hydraulic Thumb Bucket is a multi-functional attachment specifically designed for excavators. It consists of a standard bucket and an independently hydraulically driven thumb gripper. An independent hydraulic control valve in the cab controls the thumb gripper’s opening and closing. It can work with the bucket to grip irregular materials, integrating digging, grabbing, sorting, and transporting functions. It is widely used in demolition, landscaping, forestry, earthmoving, and waste recycling applications.
Precise Grasping: Works in conjunction with the excavator bucket to precisely grip irregular objects such as wood, steel, and concrete blocks from loose materials, preventing material slippage.
Multifunctional Operation: In construction demolition, waste recycling, and landscaping scenarios, it can both excavate like a regular bucket and sort and transport materials like a grapple.
Strong Adaptability: The size and gripping force can be customized according to the excavator tonnage and operational needs,making it compatible with different excavator models.
Improved Efficiency: Eliminates the need for frequent attachment changes; one device can complete multiple processes including excavation, grasping, and transportation, significantly shortening construction time.
Reduced Costs: Reduces the cost of purchasing and replacing additional attachments, and also lowers labor costs associated with manual sorting.
Material Protection: The gentle gripping force prevents damage to fragile materials such as wood and pipes, making it especially suitable for delicate operations.
As agile as a hand, as steady as Mount Tai.
With this bucket in hand, engineering tasks are worry-free.
