More Epiroc hammers for Marshalls

On the back of excellent productivity and their proven low maintenance requirements, Marshalls plc has invested in the latest versions of Epiroc’s HB 3600 IPS and HB 4100 IPS hydraulic hammers, supplied by Trojan Plant Equipment Ltd, the Epiroc dealer for the North of England. These breakers are replacing their Epiroc equivalents, which have extracted over 2.5 million tons of the hardest sandstone in England over the last five years.

Marshalls plc, headquartered in Yorkshire, has once again chosen Epiroc hydraulic hammers to boost its breaking capacity. “We extract approximately 500,000 tonnes of rock each year using hydraulic breakers at Scout Moor Quarry in Lancashire,” said Operations Manager David Smith. “With hydraulic breakers, the two key factors for us are productivity levels and reliability. We already have both an HB 3600 and an HB 4100, so we know from experience that Epiroc breakers come out top on both of these key factors.”

The key difference between the latest Epiroc breakers installed by Trojan, and the previous models that Marshalls has been using is the patented Intelligent Protection System (IPS) which simplifies the breaking process by automatically adapting the breaker’s operating behaviour to any working condition. Uptime is higher since, with its fully automated functionality, IPS requires no operator intervention or reaction and the working process is not interrupted.

The system permits more accurate and significantly faster positioning of the breaker, thanks to the centreing effect, and avoids blank firing that often results in tool damage. This also eliminates mechanical strain on the carrier and the life of all wear components is extended. The physical load on the operator is minimised as well.

Other considerations when selecting the breakers included their environmental impact. The power to weight ratio of Epiroc breakers enables Marshalls to use smaller breakers than those of other manufacturers, without reducing productivity, so increasing fuel efficiency and in turn the carbon footprint of the operation. Being super silenced as standard, Epiroc HB breakers reduce noise pollution. The on board lubricator can also be used with Epiroc’s bio chisel paste which is biodegradable.
