WAC McCandless has been trading for more than 50 years and has been a Komatsu dealer since 1961.
The range of Dynapac road construction equipment, which has recently been immersed into the Atlas Copco brand, includes pavers, small asphalt rollers and the larger soil rollers.
WAC McCandless has already bought four tandem rollers and an SD2500WS paver to promote the brand in the region.
Managing director Ciaran Carvill said: “Dynapac are a well-known and well established name with an excellent product range that fits well with our offering. The equipment is robust, reliable and is being very well received in Northern Ireland.”
