Surestrike mechanical breakers are the simple, low-cost, and dependable solution for breaking materials such as oversize rock, slag, concrete and in-ground rock. Surestrike has developed a full line of mechanical impact hammers, which break up material without the use of drop balls or high-frequency hydraulic hammers. Surestrike breakers are effectively used to break the hardest rock such as granite, iron ore, basalt and fieldstone. Softer rock such as gypsum and limestone are easily broken without tools becoming stuck. The Surestrike hammers have the power to effectively break slag and steel. Concrete is effectively demolished and the high single blow impact energy, causes the rebar or reinforcement wire to be separated from the concrete, eliminating costly secondary steps.
