Our ten years experience in the manufacturing of hydraulic breakers parts for the most famous brands all over the world, together with our customers’ huge request has brought OSA DEMOLITION EQUIPMENT to develop hydraulic breakers and to make great investments on them. The main idea was to develop a complementary product to the controlled demolition equipment.

The aim is to be always competitive thanks to a constantly improved product which satisfy our customers’ needs.

HM series has an innovative hydraulic integrated system which eliminates unsuccessful strikes, avoiding chisels, pistons and tool retainers breaks. It is a particularly “intelligent” system which recognizes the presence of sold material under the chisel. When the chisel is on the rock, the hydraulic breaker piston starts to run, spreading all its energy on the chisel. On the contrary the piston doesn’t start to work, avoiding “unsuccessful strikes” and preserving not only the tie-rods but also the bushings and reducing vibrations both on the excavator and on the operator. A closed case together with a cushions system maintains the noise low, respecting the limits established by the law. That’s why they can work in the cities.

They also have an innovative system that prevents the accidental entrance of external parts while working, guaranteeing a long duration of the whole equipment.

HM series introduces the concept of handy variable strike: it means that the operator can modify the relationship frequency/strike energy with a simple regulation. When the material is very hard, the operator can reduce the strikes number and increase the energy. On the contrary when the material is less hard, with a simple regulation, the operator can increase frequency, reducing the energy on the hydraulic breaker. This technology guarantees an considerable productivity increase.

The quality of the hydraulic breaker OSA gives the best results during excavation job and satisfies the many and different customers’ needs all over the world.
