Silenced Type 140 Diameter Chisel Hydraulic Breaker Hammer
Hydraulic Breaker Hammer
Hydraulic Breaker Hammer is one of the new front-end equipment accessories of excavator, which is widely used. Excavator hydraulic breaker has the characteristics of high strength, high power, small size and humanized product. Because the excavator hydraulic breaker can quickly and effectively break concrete, mining, boulder breaking, bridge repair, earthquake rescue and other disasters, rescue trapped people, and play a role in rescue and disaster relief. Therefore, it is often used for demolition and rescue in various places, and is a commonly used crushing tool for fire brigade, traffic police, industrial and mining enterprises and other disaster relief and construction departments. It can also be used in construction demolition operations, reinforced concrete separation and other conditions. They have a wide range of applications such as demolition, deconstruction, primary rock excavation, secondary rock breaking, trenching, foundation works, asphalt cutting, etc. Our excavator hydraulic hammers are suitable for any type of carrier, with operating weights ranging from 50kg to over 10,000kg. The over-development of breakers has given rise to different levels of advancement, such as self-lubricating systems, sound and vibration damping systems, automatic rock hardness adjustment systems, energy recovery, solid concepts, and more.
