20-200MM diamater chisel 1-50ton Durable hammer rock breaker heavy duty hydraulic breaker for all type excavator

DOPRO hydraulic hammers make short work of your demolition, construction, quarry and production breaking needs.

DOPRO are high performance breakers, designed to help you get the most from your EXCAVATOR equipment. With hammer sizes to fit skid steers, backhoes, and all sizes of excavators, you will find the breaker to fill your demolition, construction, quarry and production breaking needs.

BREAKING CONCRETE: When breaking Concrete, the breaker is expected to penetrate the material, allowing it to crack and shake loose from the reinforcing steel. High frequency breakers tend to provide better performance in this application as it is not the energy per blow, but the fast blow rate that destroys the concrete’s structural integrity. We recommend on concrete walls, footings, and floors to use a 750 – 1,500-ft. lb. breaker. With larger projects, consisting of large footings greater then 4 cubic yards, use a 2,000 – 5,000-ft. lb. breaker. The high production demand of bridge and building demolition requires a 7,500 – 10,000-ft. lb. breaker.

After considering the application work, determine the carrier on which the breaker will be installed. Gorilla Hammers has assigned a ‘Recommended Carrier Weight’ range to each breaker. If the operating weight of the carrier falls within this range, the carrier will safely handle this model of breaker. If the desired breaker falls outside of this recommended carrier weight range, the carriers lifting capacity and oil flow will need to be verified to ensure a proper fit.
Lifting Capacity: Provided the weight of the breaker does not exceed the maximum lifting capacity at any position, the carrier is assumed to be stable. On most loader backhoes and excavators, the maximum lifting capacity is lowest when the boom is at full reach. This is the value that must be compared to the operating weight of the breaker.
