Two new CB ‘Concrete Busters’ for heavy foundation work and high reach deconstruction

Epiroc has added two new models for heavier carriers to its popular CB Concrete Buster range.www.epiroc.com

The CB 5500 and CB 7500 are designed for carriers in the 50t to 85t weight class, which due to their comparatively light weight means that they are effective choices for use with high reach or long front carriers. They are also suitable for use where noise is an issue and can be used in residential areas where hydraulic breakers are not permitted.

CB Concrete Busters with their wide jaw openings and high crushing forces, have proved to be ideal for demolishing thick foundation walls whilst also making light work of ‘cracking’ girders and heavy concrete at extreme heights. They are equipped with two powerful hydraulic cylinders which deliver a virtually continuous closing force for maximum productivity. The hydraulic cylinders are fully protected by piston rod guards whilst an integrated speed valve delivers 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. Cutting blades are 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, whilst jaw openings for the models are 1,600mm and 1,800mm. The complete CB range now comprises of six models with service weights from 320kg to 7,400kg, for carriers weighing from 2t to 85t.
