Germany-based attachment specialist Epiroc is adding the CB 4500 to its popular CB Concrete Buster range.
The new model is designed for carriers in the 40 to 55 t weight class.
Epiroc says that 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 of the product 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.
CB Concrete Busters 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. An integrated speed valve gives faster working cycles.
Offering cracking forces of up to 190 t depending on the model, they are equipped with two independently moving jaws that eliminate displacement force, thus lowering stress levels. Cutting blades are both replaceable and reversible.
A 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 4500 model offers a crushing force of 130 t at the jaw tip. Jaw opening for the model is 1,400 mm (55 in). The complete CB range now comprises seven models with service weights from 320 to 7,400 kg (705 to 16,314 lb), for carriers weighing from 2 to 85 t.
