socomec BREAKERS
DMS RANGE
The new DMS breakers are built in a monoblock structure, eliminating the traditional tie-rod. The only one part which has to be assembled to the body of the breaker by using screws is the accumulator. The accumulator has a secondary function as a cap, sealing the top of the breaker. The accumulator is sealed for life and never need regassing under normal operations.
The elimination of tie-rods from the breaker also eliminates the most common cause of downtime, broken tie-rods. Moreover the serious consequences of using a breaker with an undetected broken bolt are eliminated.
Service operations are very easy and economical. By simply removing
the accumulator, all bushings and the piston are immediately accessible, with only 4 moving parts stripping out the breaker is a matter of minutes.
The monoblock structure is vulcanized in a unique body with the external case by means of a polyurethane solution.
The DMS breakers have an advanced modular hydraulic brake. When the tool is not in contact with the rock the oil supply is automatically recycled and pressure strokes are avoided (sometimes called blank firing).
A special valve stabilizes the working pressure no matter what the oil flow is. In that way it keeps the energy stroke constant.

- Noise is reduced to a minimum
- The excavator arm is protected from harmful micro vibrations

MDO RANGE
The heavy weight MDO breaker range consists of seven models, and it is able to satisfy the demands of customers with excavators from 15 to 65 tons, confirming once again the traditional characteristics of SOCOMEC’s products: reliability and technical innovation.
As regards to the inside structure, the tie rods have a new profile and an innovative tightening system, which gives them great elasticity and resistance. Moreover, the heavy weight MDO breaker range shares, together with the light weight class DMS breaker range, the exclusive advantage to be able to remove the piston and the bushes without having to loosen the tie rods.
A constant and reliable performance of the breaker is always guaranteed due to an innovative system of hydraulic oil pressure control in the input line, while an automatic variator or a hydraulic control system changes the frequency of the blows to the requested power needed for the work to be done.
The piston has been object of long and profitable studies, and is equipped with a strong hydraulic brake able to avoid harmful blank firing to the breaker. The metal case of the heavy weight class breaker range is built in high resistant steel, along with side guides in the lower part of the breaker and an innovative upper rubber pad which totally eliminates vibrations to the excavator boom.
For underwater or tunnelling applications it is possible to pressurize the stroke chamber. A new special dust proof protection on the lower part of the piston has been positioned for preventing the entrance of any impurity.
