Why it causes such problem?
The reason is that the wheel type of Hammer Grab is consisted of 6 wheels, surrounded by wire, to close & open the Bucket and is so complicated. When it impacts on the soil, Wire can be separate away from the wheel, both Wheel & Wire are wearable and consumable due to moving. What's more, wheel is often borken down and can be out of order as occurring the dirty substance.
Why We need it ?
Our Hammer Grab doesn't use such Wire and the Wheel, and can reduce such a mechanical defalut, occurred by the wheel type.
