Rammer’s Small Range hydraulic hammers are your reliable long life solution for any breaking application for carriers between 0.6 and 15 tons. Rammer Small Range hammers are built to last. Membrane-type accumulators assist with power stokes, whilst providing protection against hydraulic spikes. The field replaceable lower tool bushing and low-maintenance design ensure optimum hammer uptime, higher availability levels and reduced costs of ownership and operation.

FEATURES

  • RD3 The first ever monitoring system for hydraulic hammers – RD3. This system gives you detailed information about the operating hours, service intervals and GPS location of your product.
  • CBE (CONSTANT BLOW ENERGY) A built-in Pressure Adjusting Valve (PAV) maintains hydraulic pressure levels to ensure that every blow delivers the maximum power possible for optimum productivity. CBE operating principle enables wide accepted oil flow range and tolerates hammer against high back pressure allowing a wide range of carrier utilization. (Except 155)
  • MEMBRANE TYPE ACCUMULATOR Membrane type accumulator eliminates nitrogen leakages and removes the need for time consuming recharging. Tubular membrane type accumulator* ensures maximum piston acceleration and high impact frequency. (Except 1322E)
  • SINGLE BODY DESIGN WITHOUT TIE RODS Rammer single body design is simple and robust construction which enables ideal support and alignment for piston and tool as well as fast and easy service. (Except 1322E)
  • UPGRADED GREASING BUSHINGS AND THRUST RING Single part tool bushing with long bearing surface and thrust ring to maximize tool life. Shared retaining pin with simple locking ring allows easy replacement of tool bushing and tool. (Except 1322E)
