The Rammer RCC21R Cutter-Crusher features two powerful cylinders and 360° rotation, making it the ideal choice for both standard and high reach demolition.
Hydraulic rotation with protection valve
The protected rotation system allows precision tool placement, lowering/reducing owning and operating costs.
Shorter working cycles to increase productivity
Hydraulic cylinder shielding
The cylinders are fully protected throughout the working cycle. Increasing durability and extending service intervals.
Heat treated pins and bushings
Hardened parts are more wear resistant, extending their working life and lowering owning and operating costs
Manufactured from HB400 steel
Highly resistant material to work on concrete
Bolt on, symmetrical cutter blades
Field replaceable and ajustable cutter blades minimize downtime and signifantly increase the working life of wear parts
Concrete and stone demolition
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
rebar used extensivily in the construction industry to re-enforce concrete, as is designed to carry the tensile load.
Structural Steel is primarily removed during a demolition project by means of an attachment, with cutter blades.
