Constructor J. Murphy & Sons used compressors for vital piling work but was forced to rely on a crane to move the mobile units on and off the site. To eliminate this inefficient practice and speed up operation, the company turned to Atlas Copco for an integrated solution of frame mounted compressors with an inbuilt generator.
To eliminate the need to have a crane on site, Atlas Copco provided J. Murphy & Sons with six of its XAS 88 frame mounted compressors, which feature an inbuilt 9kVA generator. With a small footprint and weighing under 750kg, Murphy & Sons has the integrated solution that it needs on its rigs to increase its efficiency. Atlas Copco’s frame mounted compressors with integrated generator can be easily mounted on any construction vehicle, eliminating the need of using a crane on site to transport them.
In addition, the compressors were also able to meet the company’s requirements for use in piling rigs. They provided the 7 bar pressure and 175 cfm flow needed to propel an appropriately sized foam ball down the pipe for a length of up to 80 meters, while their best-in-class efficiency and fuel economy of ensured a cost-efficiency of the operation.
While the XAS 88 units were initially only brought in for compression purposes, J. Murphy & Sons was quick to leverage their full potential, putting the inbuilt 9kVA generators into good use. They are now used to power the lights in the tool cabins that accompany the piling rig. The generators have also proved useful as a portable power source for many of the handheld grinders and small welders used at the site.
