Gripping tooth
A hydraulically movable counter-holder attached to an excavator bucket is called a gripping tooth.
This combination (also of backhoes and gripper combination spoon is called) is mainly used for small excavators up to a weight of 10 tons.
Areas of application:
- cancellation
- Asphalt paving
- Clearing work
- Sorting work in the recycling area
- Moving armourstones (granite stones)
- General excavation and loading work
Similar, somewhat simpler constructions are known in the USA under the name excavator thumb ( English excavator "bagger"; thumb "thumb"). With these systems, the counter holder is attached to the excavator arm and not to the bucket.
The gripping tooth is called the thumb there because it has a similar function to the thumb on the human hand.
