Drilling Tools Impact Grab Bucket + Heavy Hammer For Exporting

When the impact excavation cannot be conducted in the rock stratum or concrete piles,use the heavy hammer to repeat the inpact,and excavate it with the impact-grab bucket after it is broken.This is a commonly adopted construction method of the cooperation of impact-grab+heavy hammer.

The grab bucket is the main internal impact excavation device of the casing.it relies on the big and small hangers of crane to complete the impact and excavation work.

During operation,the impact-grab bucket falls freely along the internal wall of casing,with the fast falling speed and strong impact force,the hard stratum can be directly impacted and excavated with a high working efficiency.

The bucket blade is in the shape of circular arc with heavy body ,it can realize the underwater impact and excavation.

With the built-in pulley block,the grabbing force is multiplied with the increasing lifting force.
