The 2,230 kg RCC21R is the best solution for standard and high reach demolition. Compatible with carriers in the 18 to 24 tonne range.
The Rammer RCC21R Cutter-Crusher features robust design, two powerful cylinders and 360° rotation, making it an efficient alternative to other demolition methods and an ideal choice for environmentally sensitive applications where low vibration, noise and dust are of concern.
The protected rotation system allows precision tool placement, lowering/reducing owning and operating costs.
The rotation is equipped with a shock valve, which limits the force applied to the structure and thus eliminates pressure spikes. This increases the lifetime of your equipment (incl. both demolition equipment and excavator).
The double bearing allows for increased load and for reduced wear with compact size.
Shorter working cycles to increase productivity
The Upside-Down cylinders have a complete cylinder protection while the hydraulic connections are fed through the piston rod.
This high-tech solution minimizes the number of parts and downtime significantly.
These state-of-the-art cylinders generate an extremely high force and have longest operating times.
The double main bearings of the crushing arms optimize the position of the cylinders to the crushing arms. This increases the crushing force and the opening width.
The double surface area of the bearings increases the lifetime of the equipment.
Your benefit is reduced costs and increased performance.
Highly resistant material to work on concrete.
Field replaceable and adjustable symmetrical cutter blades minimize downtime and significantly increase the working life of wear parts
The self-sharpening breaking teeth have no disturbing edges and penetrate the material extremely well, transferring the breaking forces optimally.
Due to this slim design, the view remains always ideal onto the demolition application.
Hardened parts are more wear resistant, extending their working life and lowering owning and operating costs
Demolition of standing buildings and structures.
Re-using parts or material which has been extracted from existing buildings or structures.
