Four new Kinshofer shears for Brown & Mason

Demolition contractor chooses Demarec DRS-45-A shears as part of major fleet investment

BROWN & Mason Ltd, one of Europe's leading demolition, dismantling and decommissioning companies, have continued their fleet investment programme with the purchase of four new Kinshofer Demarec DRS-45-A dedicated shears.

The 4.1-tonne DRS-45-A shears, supplied by Mutley Plant Services, Kinshofer’s independent dealers for London and the South East, have been dipper mounted on to Komatsu PC490 and Hitachi ZX470 excavators that have been deployed across a number of the sites which the company is currently operating in the UK.

The shears caught the eye of Lee Brown, project manager with Brown & Mason, who first operated the DRS-45 on demonstration at Kingsnorth Power Station in Kent.

‘The first thing I noticed when operating it was how quickly the jaw opened and closed in comparison to the other shears we have in our fleet,’ he explained. ‘The shear performed very well on demonstration, on a site like this we have a variety of structures and material sizes to test it on, and each time it tackled them with confidence.'

Mutley Plant Service installed the shears for Brown and Mason and will provide repair and maintenance duties to ensure the shears continue to work to maximum productivity throughout their service life. The DRS range of shears incorporates many of the design and technological features of the company’s well-renowned MQP multi quick processor range.

These include a speed valve and cylinder design that allows maximum speed throughout the cutting cycle. The design and technology also delivers cycle times in the 6s range as opposed to the 9-11s range commonly offered by other manufacturers. The power ‘curve’ remains constant throughout the closing cycle, providing a higher cutting force that results in an advantage of capability even with the increased jaw speed.

In addition, the DRS shears trunnion mounted cylinder means that the overall length of the shear is significantly reduced, improving stability and even allowing bigger shears to be fitted to the excavator.
