Montabert 501 NG Hydraulic Breaker Provides Operators
with Greater Power-to-Weight Ratio

In 1969, the legendary Montabert BRH 501 hydraulic breaker revolutionized jobsites worldwide, largely displacing popular air compressed demolition tools of the era. Today, the French attachment manufacturer presents the all-new, redesigned Montabert 501 Next Generation (501 NG) hydraulic breaker to commemorate its invention of the first fully hydraulic concrete breaker more than 45 years ago.
Despite undergoing a 30% reduction in overall weight, the 730 kg 501 NG hydraulic breaker is 75% more powerful than its predecessor – providing aggregates producers, as well as construction and demolition contractors, with a superior power-to-weight ratio.

Designed for use with backhoe loaders and excavators weighing between 8 t and 18 t, the all-purpose hydraulic breaker delivers up to 870 blows per minute – demolishing oversized boulders and thick concrete with ease. The 501 NG falls within the 1,0000 J (2,000 ft lbf) impact energy class and requires a hydraulic flow rate of between 80 and 140 l/min.

Standard performance-improving features include an energy recovery system that captures and recycles recoil energy from the piston to increase strike power and a blank-fire protection system that reduces harmful metal-to-metal contact. In addition, the 501 NG hydraulic breaker’s upper and lower suspension system extends the carrier’s work-group life by absorbing harmful vibrations and stress waves. Optional features include an air pressurization kit for underwater applications, as well as an automatic, cradle-mounted grease station that delivers continuous oil flow, reducing bushing and tool wear.

The 501 NG requires minimal maintenance. The breaker’s simple design – characterized by fewer wear parts and devoid of tie rods – enables operators to more efficiently complete routine maintenance on-site and with standard tools, including the replacement of the breaker’s bushing. The breaker’s enclosed heavy-duty housing unit further protects working parts from debris damage, while reducing noise levels on the jobsite.
