Industrial grade hand-held jackhammers, or pavement breakers, powered by compressed air and typically used to break up rock, pavement, and concrete. These pneumatic Jack hammers have the power and weight needed to demolish old concrete, pavement and other hard or unmanageable surfaces. For both results and efficiency with demolition or for digging a hole in dense, tough material such as asphalt or concrete, Jack Hammers are the go-to tool. Popular uses include road, pavement, and highway work, anything involving rocks, boulders, or stones, and personal and commercial excavation purposes. Atlantic Lift Systems carries quality Chicago Pnematic Jack Hammers in 30 lb., 60 lb., & 90 lb. sizes.
