The company, from Narberth in West Wales, has taken two Case CX350C crawler excavators, a 1021F wheeled loader and a 821F for use in its seven quarry sites throughout the region.

In the past 18 months Harries has acquired four granite and two limestone quarries. The company also runs three concrete production plants and three aggregate coating facilities, and has expanded its interests into road surfacing and other civil engineering contracting operations alongside the quarry works.

The four Case machines have been purchased to replace existing machinery as part of an overall plan to upgrade the fleet. The 35-tonne CX350C excavators are now the largest machines on the fleet and, along with the two wheeled loaders, will contribute to an increase in production levels within the quarry operations.

The company, which has more than 235 employees, runs its own service engineer division and haulage fleet.

Supplied in standard specification, the equipment is already delivering a boost in productivity for the company. With a continued growth in demand for aggregate throughout the region, Ms Phillips says the company will be looking for additional machinery before long.
