Bobcat, a manufacturer of the market-leading compact equipment, has launched the Bobcat B290 hydraulic breaker for the company's new 316 micro excavator.

'The launch of the B290 extends the applications for the 316 and is ideal for demolition and refurbishment work in confined spaces, where only machines as compact as the 316 can work,' says a spokesman for the company.
Presently the smallest model in the Bobcat range of eight breakers, the new B290 has an operating weight of just 80 kg and delivers up to 1260 bpm (blow per minute) at 28 litres/min. The B290 has an overall length of 985 mm and a tool diameter of 40 mm, similar to the Bobcat 8300 breaker.

The B290 offers the advantage of further commonality of parts and tools with the B300 as it shares the same power cell. It is delivered as a package containing the pins and bushings to adapt to the 316, hoses with flush-face quick couplers, an extra set of flush-face couplers to be installed on the 316 and a conical moil point tool.
The B290 shares the same advanced hydraulic technology offered by the other breakers in the Bobcat range, namely:

  • Blank fire protection to ensure a long service life;
  • Automatic adjustment of the operating pressure for optimised performance;
  • A diaphragm-type accumulator to maintain constant power over time;
  • A trapezoidal shock wave for efficient use of the piston energy, which is said to give the highest productivity

    With the addition of the B290, Bobcat now offers a complete range of eight breaker models for use on all Bobcat loaders and excavators, with bpm rates from 635 to 2,000 for carriers with hydraulic flow rates from 18 to 120 litres/min.

    'The B290 forms the perfect combination with the new Bobcat 316 mini-excavator,' says the spokesman. 'The latter has an operating weight of 820 kg and offers very compact dimensions - an overall width of only 750 mm, a length of 2,913 mm and a height of 2,052 mm.'

    Powered by a water-cooled 7.4 kW Kubota D722 diesel engine, the 316 mini-excavator has an undercarriage that can be hydraulically retracted or expanded, allowing access to confined spaces and increased stability in digging applications.

    'When the undercarriage is fully retracted (700 mm wide), the 316 mini-excavator can gain entry to sites through the narrowest gateways, doorways and trenches. Once the excavator is in place, the undercarriage can be expanded to 900 mm, providing optimum stability for work in-situ, he says.
