Bobcat, a business of Ingersoll-Rand, has launched the new 80 Series hydraulic breakers for carriers ranging from 700 kg to 5 tonne, which in addition to offering high performance and highly reduced maintenance, are easy to use, says a company spokesman.

The innovative design pioneers a completely new way of working with a breaker in that for the first time ever, either a bucket or a vibrating plate accessory can easily and quickly be fitted onto the breaker, he adds.
Designed for trenching, concrete demolition and general excavation work, the new Bobcat breakers feature a frame with a cylindrical design, providing improved access to jobs in confined areas such as inside structures or holes. The breakers are standard, equipped with a special shield to protect hoses and fittings from being damaged when working close to the ground or in tight spots, he points out.
The innovative design of the breaker hydraulic system provides increased efficiency, ensuring a longer working time without risk of overheating.
The breakers also incorporate a very effective soundproofing system, whereby the striking assembly is held both at the top and bottom by suspension systems that are not in contact with the outer cylindrical housing.
In addition, the new breakers also present a completely new internal design with fewer moving parts and no tie rods a result of which they can be completely disassembled in less than five minutes, without the need for special tooling, reducing maintenance costs even further.
Another novel feature of the new breakers is a patented treated steel ring ‘clip’ system, which retains the bushing of the tool and protects the greasing system. This ring is easily removed with a multi-purpose tool supplied with the breaker, to instantly release the sliding bushing and the tool.

Increased versatility
The new breakers also introduce a new work concept for increased versatility and productivity by allowing the breaker to be fitted with a bucket or a vibrating plate accessory.
The bucket accessory, which is fitted mechanically, does not need any hydraulic connection and the bucket flange has been designed to match with the bottom of the breaker housing, he says. The tool on the breaker is positioned in the casing and the operator can then lock the device with a retaining pin. This ‘breaker and bucket’ assembly enables the operator to clear debris quickly and easily with the same machine without using any other equipment.
By fitting the vibrating plate accessory, the breaker can compact materials without any additional hydraulic connections. When refilling the trench, the operator can use the breaker with vibrating plate accessory to compact the fill material in the trench.
