Two new CB ‘Concrete Busters’

Published 21/4 at 13:22

Epiroc is adding two new models for heavier carriers to its popular CB ‘Concrete Buster’ range. The CB 5500 and CB 7500 are designed for carriers in the 50t to 85t weight class. Due to their comparatively light weight, CB Concrete Busters are effective choices for use with high reach or long front carriers for applications with highly abrasive material and low level of visibility in operation. They are also suitable where noise is an issue and they can be used in residential areas where hydraulic breakers are not permitted.

As many construction and demolition contractors worldwide have discovered, CB Concrete Busters, with their wide jaw openings and high cracking forces, are ideal for demolishing thick foundation walls, making light work of cracking girders and heavy concrete at extreme heights. They are equipped with two powerful hydraulic cylinders which deliver virtually continuous closing force for maximum productivity. The hydraulic cylinders are fully protected by piston rod guards, with an integrated speed valve providing faster working cycles.

Offering impressive cracking forces of up to 190t depending on the model, CB Concrete Busters are equipped with two independently moving jaws that eliminate displacement force, thus lowering stress levels, with cutting blades being both replaceable and reversible. A productive feature on all CB Concrete Busters is 360° endless hydraulic rotation, which allows 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 effectively protects both the carrier and the cutter from potentially damaging reaction forces.

The new CB 5500 and CB 7500 models offer cracking forces of 150t and 190t respectively with jaw openings for the two models being 1,600mm and 1,800mm respectively. The complete CB range now comprises of six models with service weights from 320kg to 7,400kg, for carriers weighing from 2t to 85t.
