Daemo DMB Standard Series Hydraulic Breaker Hammer For Excavator Rock Breaking

Product Introduction

The Daemo DMB Standard Series Hydraulic Breaker Hammer For Excavator Rock Breaking is designed for excavator-mounted demolition, rock breaking, quarrying, mining, road construction, trenching, foundation excavation, concrete breaking, and heavy-duty construction applications. This hydraulic breaker hammer belongs to the DAEMO DMB Standard Series, covering common models such as DMB50, DMB70, DMB90, DMB140, DMB180, DMB210, DMB220, DMB230, DMB250, DMB300, DMB360, and DMB450.

A hydraulic breaker hammer is one of the most widely used excavator attachments for breaking hard materials. It converts hydraulic power from the excavator into high-impact striking force, allowing the operator to break rock, reinforced concrete, asphalt, foundations, pavement, and other tough materials. For contractors, quarry operators, mining companies, rental fleets, and demolition teams, choosing the right hydraulic breaker hammer can improve job site productivity and reduce operating costs.

The Daemo DMB Standard hydraulic breaker hammer is suitable for different excavator sizes and working conditions. From small demolition jobs to medium and heavy rock breaking applications, the DMB Standard Series provides practical solutions for customers who need stable impact performance, reliable structure, easy maintenance, and good parts availability.

This product page is focused on hydraulic breaker hammers and related aftermarket replacement parts for the DAEMO DMB Standard Series. The DAEMO brand and DMB model names are used for product identification, compatibility, and application reference.

Product Materials

The performance of a hydraulic breaker hammer depends strongly on the quality of its main materials and internal components. The main body, cylinder, front head, back head, piston, bushings, chisel, bolts, seal kits, and diaphragm must work together under high pressure and continuous impact.

The breaker chisel is commonly produced from 42CrMo or equivalent alloy steel, with heat treatment to improve wear resistance, toughness, and impact strength. The piston can be produced from materials such as 40Cr, 42CrMo, 40CrMnMo, or 40CrNiMo, depending on working condition and customer requirements. These materials help the piston resist repeated impact stress and maintain stable energy transfer.

The inner bush, outer bush, thrust ring, front head, back head, through bolts, side bolts, and wear parts are made from selected alloy steel or suitable wear-resistant materials. The seal kits may include FKM, PU, NBR, PTFE, rubber, and backup ring materials for oil resistance, pressure resistance, and sealing stability. The diaphragm is normally made from rubber or rubber-based composite material to separate nitrogen gas and hydraulic oil inside the accumulator system.

Good material selection helps the hydraulic breaker hammer work more reliably in demolition, quarrying, mining, and road construction environments.

Product Features

The Daemo DMB Standard Series hydraulic breaker hammer is designed for powerful impact, stable operation, and practical maintenance. Its structure is built to support continuous breaking work on excavators, including rock breaking, concrete removal, asphalt cutting, foundation demolition, trenching, and secondary crushing.

The breaker hammer is engineered to deliver efficient impact energy from the piston to the chisel. A properly matched piston, cylinder, seal kit, accumulator, bushings, and chisel can help maintain stable striking force and reduce energy loss. Stable impact performance is important for improving work efficiency and reducing fuel consumption during long working hours.

The front head system supports the chisel, inner bush, outer bush, thrust ring, and rod pin. This area guides tool movement and helps reduce abnormal chisel shaking. The back head and accumulator system help support pressure stability and impact performance. The through bolts and side bolts secure the breaker structure and help maintain body alignment under vibration.

The DMB Standard Series is also designed for serviceability. Key wear parts such as chisels, seal kits, bushings, rod pins, through bolts, side bolts, diaphragms, front heads, back heads, buffers, and wear plates can be replaced during repair and maintenance. This makes the hydraulic breaker hammer suitable for long-term use when maintained properly.

Main Advantages

The main advantage of the DAEMO DMB Standard Series hydraulic breaker hammer is its wide application range. It can be used in construction, demolition, quarrying, mining, road repair, trenching, foundation work, and concrete breaking. Contractors can use it for building demolition, reinforced concrete breaking, bridge repair, pavement removal, and municipal construction. Quarry and mining customers can use it for secondary rock breaking, stone splitting, and hard material reduction.

Another advantage is parts availability. Hydraulic breaker hammers work in harsh conditions, so replacement parts are important. Chisels, pistons, bushings, seal kits, diaphragms, rod pins, bolts, front heads, back heads, buffers, and wear plates are common maintenance items. Easy access to correct parts helps reduce downtime and improves repair efficiency.

A properly selected hydraulic breaker hammer can also help protect the excavator. When the breaker is matched correctly with the excavator carrier, hydraulic flow, pressure, operating weight, and tool size, the equipment can work more safely and efficiently. Incorrect matching may cause weak impact, overheating, hydraulic problems, or premature wear.
