160mm chisel diameter heavy duty durable Excavator Attachment HB40G HB50G Jack Hammer Rock Breaker Hydraulic Breaker

The breakers of the us , thanks to their power and efficiency and to the right ratio between weight and power, are suitable for secondary demolition work, excavations in quarry, work in urban areas, tunnels, pipelines and railway tunnels and, concerning the biggest models, demolitions in open pit mining.

Models for excavators with operating weight from 8 to70 ton
Tubes with swivels fully protected from any bad uses and resistant to vibrations in case of lack of nitrogen in the chamber.
, it is possible to adjust the working pressure by a manual valve located frontally, on the distribution of the breaker.
Anti-dust and underwater work set up You can prevent the entry of dust and water into the breaker by blowing air into the proper hole in the front part of the breaker, with a pressure not less than 10 bar.
Automatic hydraulic greasing device (optional, mounted on the breaker) The Beka-Lube automatic lubrication system optimizes the lubrication procedure and reduces maintenance and downtimes.

Automatic hydraulic greasing device with exclusive Hammer electric control (optional, mounted on the excavator). Innovative electric system with automatic grease distribution, less liable to vibration breakages thanks to its own tank of grease with a capacity of 4 kg or 8 kg, making thus the system cheaper than all the other devices with single cartridges.

The regulation of the blows is carried out manually by an adjusting valve located on the side of the breaker.
Hydraulic system for blank firing the hydraulic system is a regenerative circuit of oil that avoids blank firings when the tool is not in contact with the rock.
The piston is built with a special geometry such as to keep a constant energy of impact, as well as for reducing breakages in conditions of criticality.
Anti-dust system for tunnels (optional) The anti-dust system consists of the addition of a dustproof seal mounted in the lower bush so to avoid the entering of impurities in the circuit.

Hydraulic Breaker applications
demolition applications, concrete breaking
closed mines, scaling
open mines, boulder breaking
tunneling
underwater applications
frozen soil breaking
rock breaking

Constant blow energy
Low wear, resulting in high secondhand resale value of a breaker
Low thermal heat of oil means energy savings for end user
Good hydraulic shock absorption
Less maintenance of hammers, and therefore lower costs
Hammers have well designed hydraulics to minimize overheating.
The buffer system (side, top and bottom buffers) that is used in Red breakers, has a special impact and vibration absorbing properties.
Easy changing of tools
Noise isolation sheets as standard
Side rods are covered with the polyurethane to reduce stress and vibration on the thread
wear resistant steel bushings
