HD Hyundai is launching a new range of silenced hydraulic breakers.
The HRB Series will feature six models for excavators from 1.2-26 tonnes operating weight.
All feature a silenced box housing to reduce external noise levels, making them suitable for urban sites. They have a urethane damper to prevent vibration being transmitted to the carrier machine, reducing wear and improving operator comfort. The front head assembly also incorporates a bushing to reduce shocks from the working tool.
HD Hyundai added that ‘high-quality’ steels are used in the main cylinder and piston, with an advanced heat treatment process delivering ‘best-in-class’ service life for the main through-bolts.
A choice of tools includes a conical moil point for demolition, concrete and hard ground. A pyramidal moil point can be used for trenching, general excavation, asphalt, quarrying, and reinforced concrete.
The flat wedge chisel is also described as ‘ideal’ for trenching and general excavation work, along with mass excavation in quarries and for reinforced concrete demolition. A blunt flat end is designed for block splitting, compacting abrasive materials, and concrete slab demolition work.
Several options are available on the two larger breakers. All HRB140 and HRB250 models come with auto greasing through a front head grease hole and a cylinder head grease hole. HRB140 and HRB250 models can also be ordered with anti-blank firing technology. The HRB250 is available with a nitrogen gas accumulator in the back head section, increasing the impact energy of the piston. The HRB030 is designed for mini-excavators with operating weights of 1.2 to three-tonnes.
All HD Hyundai HRB Series breakers are delivered with a choice of two chisels and come with a standard two-year warranty.
