Atlas Copco develops high-performance compact hydraulic breaker

0

Atlas Copco has developed a lighter and more compact hydraulic breaker without impinging on performance.

Weighing 1,650kg, the MB 1650 offers higher reliability, lower repair costs and easier accessibility for maintenance than its predecessor. The new model replaces the heavier MB 1700 as the company’s provision for carriers in the 19-32 tonne weight class.

A new design of the vehicle’s service window provides greater access, allowing for less hassle when carrying out maintenance checks; and with no high-pressure accumulator, maintenance and repair costs for the MB 1650 are lower than the outgoing model.

An automatic piston length switching system optimizes breaking performance by adjusting the output balance between impact energy and rate during operation, while an energy recovery feature automatically utilizes the piston recoil energy, to increase the performance without additional hydraulic input, and lowers vibrations.

The integrated start/select valve enables the operator to adjust the hydraulic breaker start-up behavior according to the operating condition in a few simple steps.

The MB 1650 is equipped with Conti Lube II, a self-bleeding automatic lubrication device for optimized grease consumption and continuous lubrication.

Noise and vibration levels are minimized by the Vibro Silence Plus system, utilizing non-metallic suspension arrangements to isolate the percussion mechanism from the breaker box and sealing all openings for lower noise and vibration levels.

An optional, patented dust sealing system called Dust Protector II will extend the service life of the components and reduce grease consumption. The built-in check valve reduces dust intake into the tool guiding area and the percussion chamber.

An Atlas Copco spokersperson said, “The new MB 1650 hydraulic breaker is an efficient choice for a broad spectrum of applications in mining and quarrying, demolition and renovation, construction, and the metallurgical industry.”
