Hd Hyundai launches a range of silent hydraulic breakers

With its stated mission to continually improve the versatility and productivity of its extensive line of wheeled and tracked excavators, Hd Hyundai introduces a series of silenced hydraulic hammers. Packed with many innovative features, the hammer Series Mr they are designed to provide superior performance and high-impact energy.

Hrb hammers are supplied internally six dimensions, and different measurements for larger models. L’a muted box house provided by all hammers reduce noise levels, making them perfect for use in urban construction sites. They have urethane-based damping materials that prevent the transmission of vibrations to the carrier machine, reducing wear and improving operator comfort. The front head assembly also includes that bushing reduces the shock produced by the instrument.

For the master cylinder and its piston are used high quality steel, with an advanced heat treatment process that provides a high quality service life for the main through bolts. A selection of high quality bits including: conical bit for breaking concrete and hard ground, pyramid bit suitable for trenching, general excavation, mining work, asphalt and reinforced concrete. No doubt, flat cutting tip it is good for digging trenches and trenches in general, but also perfect for heavy excavation work in quarries / mines and for the destruction of reinforced concrete. at the end, blunt cutting tip It is designed for splitting blocks, joining abrasive materials and for concrete slab damage work.

• Hrb030 is designed for small excavators with an operating weight between 1.2-3.0 tons. The power breaker has an impact rate of 700-1,200 bpm.
• Hrb040 is suitable for small excavators 2.5-4.0 te boasts an impact rate of 600-1,200 bpm. Hrb050 with an impact frequency of 500-900 bpm is suitable for machines in the weight category 4.0-7.0 tons.
• Part of Hrb060 and impact frequency of 400-800 bpm is ideal for 6.0-9.0 ton machines.
• L’Hrb140 with 350-700 bpm it is ideal for large excavators in the 10-15 ton category. Hrb140 is offered in three specifications: with automatic lubrication, with the “anti-blank firing” system or with both options.
• L’HRB250which is an example the largest in the series, designed for machines 18-26 t. It has standard equipment with a collector and automatic lubrication, and, on request, it is also available with “anti-blank firing” technology.

There are several options available for two larger hammers.

All Hrb140 and Hrb250 models have automatic lubrication through the front grease hole and the cylinder head grease hole. Models of Hrb140 and Hrb250 can also be ordered by technology empty sound barrier (anti-empty firing). Hrb250 is produced by the accumulation of nitrogen in the rear part, which increases the impact energy of the piston.

All Hyundai Hrb HD Series hammers are offered with the option of two tips and is covered by the manufacturer’s standard two-year warranty. Although designed to provide high performance with the Hyundai A Series HD range of excavators, HRB breakers can also be used with other machine brands, meeting the needs of customers with mixed fleets.
