Special steel material with high ductility and high resistance The working efficiency is 3-5 times as the original hammer in the sandstone, weathered rock, partly limestone and karstform limestone, etc. It can be installed on the hydraulic excavator. The power is provided by the hydraulic pressure system on the excavator. The installment is easy with convenient and flexible operation It is a new product that the crashing power is produced by centrifugal force which is driven by motor reciprocating motion More outstanding efficiency, energy-saving and environmental protection. Original imported motor, more durable, high swinging speed, higher torque, and stronger striking force, big and faster frequency. Gear holder and tip are originally imported from America with higher impact resistance and durability.
