The minimum amount of CLAWS for your machine depends on the weight of the machine. Per 2 ton operational weight should be calculated 1 CLAW so it would be for a 20 ton exacavator 10 pieces

The CLAWS increase the traction between surface and machine. But the decline and incline limits set by the machine manufacturer must not be exceeded.
