The Residential Concrete Breaker is a portable, electrically powered drop-weight machine. A chain-driven lifting mechanism raises a vertically guided striker using an electric gearmotor equipped with a spring-applied brake. At the latch position, the striker is retained until the electrically actuated latch releases it. Gravity then accelerates the striker downward to deliver impact directly to the concrete.

Major Components
Component |
Purpose / Operator Check |
Main frame |
Structural foundation. Inspect for cracks, loose fasteners, bent members, or transport damage. |
Guide rail assemblies |
Control vertical striker movement. Keep clean and inspect for wear, weld damage, deformation, and debris. |
Striker |
Approx. 350 lb working mass that delivers impact. Do not modify weight or geometry without manufacturer approval. |
Chain lift assembly |
Raises the striker. Includes sprockets, ANSI chain, tensioner, and slack-management enclosure. |
Gearmotor & brake |
Supplies lifting power; spring-applied brake prevents unintended lift-system movement when power is removed. |
Solenoid release & latch |
Retains and releases the striker. Release and reset must occur positively every cycle. |
Transport lock |
Mechanically secures the striker for transport, inspection, and service. |
Safety guards |
Protect personnel from moving mechanical components. Operate only with guards installed. |
Caster wheels |
Permit manual positioning on solid supporting surfaces. |
IMPORTANT: Normal operation is: position the machine, deliver one or more impacts, move backward onto intact concrete, and reposition. Do not roll forward across fractured concrete or demolition debris. |
