The building and civil engineering company has also bought five Cat 320E LRR hydraulic excavators, bringing its total fleet of Cat machines to 25.
The zero-tail swing machinery is built to meet European Union stage IIIB emission standards.
John Coll, division director of plant, transport and procurement at J Murphy & Sons, said: “As a business, we operate in a multitude of different applications that can prove to be challenging when matching plant equipment. We found Finning encompassed everything we were looking for in terms of equipment, back-up support and cost.”
As part of the deal, each machine will benefit from a two-year preventative warranty and the back-up support of the nationwide network of Finning branches and on-call engineers.
The machinery meets J Murphy & Sons zero accident policy, with both companies achieving RoSPA Gold Awards.
