Compact, efficient and powerful, the new US Hammer GB-70 is easy to transport from job to job. With 64 pounds of impact force, it delivers the same power-to-weight ratio as many pneumatic and hydraulic breakers. Its quiet, portable four-stroke Honda gasoline-driven design makes it easy for setup and handling, and the vibration-reducing technology reduces damage to an operator’s joints and shoulders. It keeps crews safer by eliminating the need for a big, dangerous air compressor.
