The firm, which operates across Central Scotland, has invested heavily in its fleet of equipment to serve civil engineering customers delivering infrastructure for renewable energy projects.

It has recognised this growth area as the Scottish Government strives to meet its target of providing 50% of Scotland’s electricity from renewables by 2020.

Director Tom Blackwood Jnr said: “We were quick to recognise the opportunity to provide plant to serve the renewables and rail sectors and developed our fleet and expertise accordingly.

“We have chosen JCB machines this year as none of its competitors could provide the same performance, value for money and backup.

“The excavators themselves are excellent, with the JS200 models especially impressive. We have a great relationship with our dealer Scot JCB while the package from JCB Finance has allowed us to expand our fleet at the speed necessary to maximise the opportunities available.”

The new JCB machines comprising one 8025, one 8085, four JS130, five JS145, one JS160 LGP (Low Ground Pressure) and three JS220 models.

This takes the total number of JCBs to 48, which now represents nearly half of Blackwood’s 105 machine line-up.

The investment has been funded by Blackwood’s success in landing a series of renewable energy and rail contracts and the new models have already been put to work.

The new JS160 LGP model with its 1500mm wide tracks has been responsible for drainage work at Elvanfoot in South Lanarkshire as part of the high profile £600 million Clyde wind farm project.

The JCB has been excavating drainage channels in the surrounding grassland to counteract the impact of the wind farm’s infrastructure.

This will ensure the area’s natural water levels are maintained so sheep can continue to graze.

The new wind farm will ultimately feature 152 wind turbines with a maximum total generation capacity of up to 456MW – enough energy to power over 200,000 households.
