Epiroc, Commerce City, Colorado, has added two new models to its Combi Cutter range. Designed for carriers in the 20 to 30 ton and 25 to 40 ton operating weight classes respectively, the CC 2300 and CC 3100 are designed to have a combination of short cycle times, easy handling and simple maintenance.
The CC 2300 and CC 3100 have all the well-known features of the Combi Cutter range. The machines are designed with low noise, low vibration operation and to be suitable for any kind of primary demolition work. The cutting blades on all versions are replaceable and reversible, and the attachments can be equipped with different sized jaws according to requirements.
Like other attachments in the CC range, the CC 2300 and the CC 3100 are available with two jaw versions, the universal version (U) and the steel cutting version (S). The universal versions are ideal for light- to medium-duty building demolition and heavy-duty industrial demolition involving heavily reinforced concrete. The steel cutting versions are specifically designed for cutting steel profiles in general steel structures. Both versions can be used for secondary reduction and material separation.
The CC 2300 and the CC 3100’s stable cutter body features two hydraulic cylinders with integrated speed valves designed for minimum cycle times and minimum fuel consumption. Fully protected by piston rod guards, the cylinders deliver virtually constant closing force designed to remain high even when the jaws are almost closed. Two jaws moving independently eliminate displacement forces on the cutter and the carrier, Epiroc says, ensuring controlled demolition of unstable concrete walls, regardless of which jaw attacks the material first.
The hydraulic drive gives 360-degree endless rotation designed for precise handling and optimal positioning. If the cutter grips the material at an oblique angle, a built-in pressure relief valve allows a “self-acting movement” that brings the cutter jaw into the ideal position. This valve protects the carrier and the cutter from potentially damaging reaction forces.
The cutter jaws can be changed on-site because of their modular design and mounting on one central bearing pin. The caps coupling and positioning system is designed so the two jaws can quickly be removed and refitted as one unit. Caps makes handling of the dismounted jaws much easier as the two jaws remain connected, Epiroc says, even after they have been removed from the body. Refitting is simple using the special guide system supplied.
