Breakers

Promaxx™ paving breakers

Available in 60 and 90 lb. capacity versions, they deliver more power than competitive tools, with one-third fewer parts, easier maintenance, and a host of ergonomic and convenience features. The unique design of the Promaxx paving breakers is based on extensive input from actual users. For example, the spring-loaded anvil bushing keeps the tool firmly pressed against the work surface, while reducing vibration to the operator. The four bolt backhead is contoured to fit the operator’s leg and provides for fast removal and service. Optional flex handles help absorb vibration in a full 360 degree range of motion, improving comfort and control far better than spring-mounted handles. And the optional muffler kit is attached with a single bolt, simplifying field additions. The front head and cylinder housing are backed by a three-year warranty, while all other components are covered for one full year.

Low vibration – High Performance

Ingersoll-Rand, acclaimed throughout the construction industry for the reliability and consistent performance of their handheld tools, now introduce two new paving breakers designed to meet the demands of the industry regarding productivity standards and environmental concerns relating to handtool vibration and noise limitations.

Operator comforts

The PB50ASF and PB60ASF provide an approximate 65% reduction in handle vibration levels compared with standard breakers the same size. The vibration resisting characteristic of the tool is achieved by the simple yet efficient handle design which enhances operator comfort and allows work for longer periods with less fatigue. Furthermore, the well-balanced design allows the operator full control of the breaker whilst in operation. Fewer moving parts, by design, make servicing and maintenance a simple and cost-effective process.

Power and productivity

In field tests, Ingersoll-Rand vibration-reduced breakers achieved the same consistency in their production and penetration capabilities as standard breakers, whilst at the same time reducing the exposure of the operator to vibration, in both working and pullback modes.

Exploit new opportunities

In a tough and robust environmental the Ingersoll-Rand breakers will handle any construction, demolition and utility application economically with a minimum amount of maintenance.
