Epiroc EC Series Rock Breaker Hammer For Excavator Demolition And Trenching Jobs

Product Introduction

The Epiroc EC Series Rock Breaker Hammer For Excavator Demolition And Trenching Jobs is designed for excavator-mounted breaking work in construction, road repair, landscaping, utility trenching, concrete removal, foundation work, and light to medium demolition applications. It is suitable for Epiroc EC Series hydraulic breaker hammers, including common models such as EC40T, EC60T, EC70T, EC80T, EC90T, EC100T, EC120T, EC135T, EC140T, EC150T, EC155T, EC165T, and EC180T.

A hydraulic breaker hammer is an important excavator attachment used to break concrete, asphalt, rock, pavement, bricks, foundations, and other hard materials. Compared with manual breaking tools, an excavator-mounted hydraulic breaker provides stronger impact force, better working efficiency, and lower labor cost. It is widely used by construction contractors, demolition teams, municipal projects, equipment rental companies, repair workshops, quarry operators, and machinery parts distributors.

The Epiroc EC Series is often selected for jobs where flexibility, stable impact output, and easy maintenance are important. Whether the breaker is used for sidewalk removal, trench preparation, secondary concrete breaking, small quarry jobs, building renovation, or foundation repair, correct hammer selection and proper spare parts support can help reduce downtime and improve working efficiency.

Materials And Main Components

A hydraulic breaker hammer is made of several key systems, including the cylinder body, piston, front head, back head, chisel, bushing system, seal kit, diaphragm, accumulator, bolts, rod pins, buffer parts, and wear plates. Each component must work together under hydraulic pressure, impact vibration, and long working hours.

The breaker chisel is commonly made from 42CrMo or equivalent alloy steel, with heat treatment to improve wear resistance and impact toughness. The piston can be produced from materials such as 40Cr, 42CrMo, 40CrMnMo, or 40CrNiMo, depending on working condition and customer requirements. The cylinder body requires accurate machining, smooth inner bore, and stable pressure support to guide piston movement.

The inner bush and outer bush are usually made from wear-resistant alloy steel to guide the chisel and reduce abnormal tool shaking. The seal kit may include FKM, PU, NBR, PTFE, rubber, O-rings, oil seals, and backup rings to support hydraulic oil sealing. The diaphragm is commonly made from rubber or rubber-based composite material to separate nitrogen gas and hydraulic oil in the accumulator system.

Reliable materials and accurate machining are important for maintaining hydraulic breaker impact performance, reducing oil leakage, and extending service life.

Product Features

The Epiroc EC Series hydraulic breaker hammer is designed to convert excavator hydraulic power into impact energy. Hydraulic oil drives the piston to strike the chisel, and the chisel transfers the force into concrete, rock, asphalt, or other hard materials. A stable breaker should deliver consistent impact, smooth tool movement, and reliable structural strength during operation.

One key feature of the EC Series breaker hammer system is its wide application range. It can be used for concrete demolition, road surface repair, trenching, foundation breaking, utility construction, and general rock breaking jobs. For contractors who work in urban areas or confined job sites, a properly matched breaker hammer can help complete breaking tasks efficiently without using larger equipment.

The front head system holds the chisel, inner bush, outer bush, rod pin, and related guide parts. This area controls tool movement and helps reduce shaking during impact. The cylinder and piston system creates the main impact force. The seal kit prevents hydraulic oil leakage, while the diaphragm and accumulator help support pressure balance and impact energy control.

Easy maintenance is another important feature. Common replacement parts include chisels, pistons, seal kits, bushings, diaphragms, rod pins, side bolts, through bolts, front heads, back heads, cylinders, buffers, and wear plates. With correct spare parts support, the breaker can be maintained more efficiently and returned to work faster.

Main Advantages

The main advantage of the Epiroc EC Series rock breaker hammer is its practical performance for excavation and demolition jobs where controlled breaking is required. It is suitable for contractors who need a breaker for concrete slabs, curbs, foundations, pavement, trenching, and smaller rock breaking tasks.

For road construction teams, the breaker can be used for asphalt removal, pavement repair, and municipal maintenance. For building renovation and demolition work, it can break reinforced concrete, old floors, walls, and foundations. For landscaping and utility projects, it can help open trenches, remove hard ground, and prepare construction areas.

Another advantage is repair convenience. Hydraulic breakers work in harsh conditions, so spare parts availability is very important. If a seal kit leaks, a bushing wears, a chisel breaks, or a piston is damaged, quick replacement can reduce machine downtime. For equipment rental fleets and repair workshops, keeping the correct EC Series spare parts in stock can improve service speed.

Choosing the correct breaker hammer also helps protect the excavator. The breaker should match the excavator carrier, hydraulic flow, working pressure, operating weight, and job type. Incorrect matching may cause weak impact, overheating, hydraulic system stress, fast wear, or poor breaking efficiency.
