Epiroc SB hydraulic breakers feature integrated water port for dust suppression
Epiroc's premium SB series hydraulic breaker attachments are, according to the company, the industry's only breakers to come standard with an internal water port for dust suppression, a feature that can assist in compliance with Occupational Safety and Health Administration (OSHA) final silica rule dust regulations.
With an integrated water channel, operators can spray water at the source of dust creation to keep dust levels down. This improves the working environment, enhances visibility and prevents dust from seeping into the bushings. SB breakers are also designed to protect operators and equipment by reducing noise and vibration.
Epiroc SB series breakers are designed for the 0.7- to 24-ton carrier class and are used in a wide range of applications that include demolition and renovation work, construction projects, tunnelling, dredging and pile driving. Mining and quarrying applications range from overburden removal and scaling to primary, selective rock breaking.
SB series breakers combine superior efficiency and performance with high durability in a compact design. The range includes models to match any micro or mini excavator, backhoe, skid-steer loader or demolition robot with service weights ranging from 120 pounds for the SB 52, the smallest breaker of the SB series, to 2,350 pounds for the SB 1102. Oil requirements range from just 3.2 gpm at 1,450 to 2,175 psi, to 35 gpm at 1,185 to 2,610 psi.
Efficiency in design
Epiroc EnergyRecovery technology absorbs recoil energy, mitigating anvil effect and increasing overall performance. The result is higher impact rate from the same hydraulic input with less vibration. The slim, compact design makes SB breakers easier to handle and improves operator visibility.
All SB breakers come prepared for compressed air supplies. No modification or additional installations are required. The multifunctional design of the well-protected connection ports assures trouble-free operation, ease-of-service, and quick access. Side-positioned ports reduce risk to hoses and provide easy access for connecting compressor, water connection or ContiLube II micro lubrication supply lines or for monitoring operating pressure.
No special tools or adaptor fittings are required for servicing SB series breakers. The SB SolidBody concept utilizes a patented internal, integrated component design integrating the impact mechanism and the guide system into a single piece. This eliminates the weakest components of traditional breakers: damping and guiding elements, tie rods, parting lines and stud bolts.
The accumulator is cast into the body, further reducing the number of breaker parts and overall weight and maintenance. Gas pressure can be checked and adjusted in a matter of minutes. The supported diaphragm reduces strain and distortion, improving load distribution and service life.
Dual tool retainer pins optimize tool load distribution, require less grinding and protect against accidental damage to the tool and breaker.
Other standard features of SB breakers include integrated pressure relief valve for overload protection, Auto Start, air inlet for underwater applications, oil drainage plug, dust wiper, slip fit bushing and dual tool retainer bars for better support.
Epiroc ContiLube II or ContiLube II micro are options available for SB series hydraulic breakers.
As one of the latest models in the R2-Series excavator lineup, the Bobcat® E88 delivers durability, performance and quality for more productivity. Technically speaking, it's a compact machine, but it brings big performance with its redesigned engine and optimized lift performance, plus undercarriage and counterweight improvements. All these enhancements make this excavator one of the highest-performing models in its size class. With impressive over-the-side lift capacity, you can dig with greater confidence over the side of the machine. Put it to the test against similar models from other manufacturers. You'll see that the E88 can outwork the competition.
