This is the Lego Power Miners Set 8957, Mine Mech.
The one-of-a-kind Mine Mech is an experimental mining walker built to go where the other Power Miners vehicles can't. The enhanced movement and armor make it perfect for exploration and emergency rescues. Its spinning plasma cutter and crushing claw make it more than a match for any rock or rock monster.
