Dig A Crusher Tackles Forestry Road Repairs

A Scottish contractor and plant hirer is employing a Dig A Crusher 1200 attachment to tackle the ongoing repair and maintenance of forestry roads damaged by local logging activities

Stirling-based contractor and plant hirer Christie Plant Ltd is using a newly-acquired Dig A Crusher 1200 to help carry out vital road repair and maintenance duties in the forests of the beautiful Trossachs National Park. The 1 m3 crusher bucket attachment is being used to rectify damage to the forestry roads caused by intensive logging in the area.
Logging Operations

Trossachs National Park is located just north of Loch Lomond, and just a few miles to the west of Aberfoyle, the gateway to the Queen Elizabeth Forest. This huge forest is actively managed by the Forestry Commission, which harvests the valuable natural resources. Due to the relatively intense nature of the logging process, it is not unusual for as many as 15 heavy trucks to be operating in close proximity. These vehicle movements do enormous damage to the unmade forestry roads that are frequently washed away during winter months. In a bid to overcome this, the Forestry Commission has started to use road trains in the area to reduce the level of vehicle movements. Unfortunately, this has placed additional pressure on the roads in another way, through increased axle weights.

The Commission has, therefore, started to improve the roads and actively employs contractors to repair and maintain them in a sustainable and environmentally sympathetic manner.

“We were delighted to be included as one of the named contractors capable of doing this vital and environmentally-sensitive work,” says Callum Christie. “But we soon realised that the excavators we were planning to use to tackle this work could, in fact, cause even greater damage to the forestry roads. We needed a system that would allow us to carry out the necessary repairs with the minimum possible number of vehicle movements.”
Resilient Surface

Part of the solution was to use rock won from quarries hidden within the forested area, thereby avoiding the need to import material and causing yet more damage to the roads. One such quarry is providing slate that forms an ideal sub-base; a second quarry is providing hard Winstone as a durable surface course. The second part of the solution came in the shape of the Dig A Crusher 1200 attachment coupled with a newly-purchased 30 tonne class Hitachi DX340LC hydraulic excavator. “The Dig A Crusher 1200 has not only proved to be the answer to the problem of how to provide material for the roads at a viable price; but also how to carry out localised repairs whilst doing minimal damage to an already damaged site,” Callum Christie says. “The 1200 allows us to use just one machine instead of the usual two. It also allows us to process local rock on site and do the repair quicker, more effectively, and with far less risk of further damage.”

Christie reports that the Dig A Crusher 1200 attachment reduces blasted Winstone rock to a size of >150 mm which provides the forestry roads with a resilient, hard-wearing surface. Such has been the success of the Dig A Crusher solution that Christies is now crushing a stockpile of blasted rock at the 1.0 hectare Craigie Quarry near Aberfoyle, purely for this application. “The 1200 is processing Winstone at a rate of 70-80 tonnes/hour. In its first 45 hours of operation, it processed nearly 2,400 tonnes of rock,” Christie concludes. “The Dig A Crusher bucket has turned out to be every bit as good as we hoped it would be. In fact we have already been showing it off to other potential customers. It will be interesting to look at the final production figures. The set up of the new excavator and the Dig A Crusher is the cash equivalent of three 16 tonne class excavators. But taking into consideration we are only using one operator and one lot of fuel, the Dig A Crusher bucket already looks to be a sound investment.”
