After six months of development Morrison Utility Services has introduced a new tool to its workforce designed to help excavate hard ground around utility pipelines.
The Air-Ex air excavating lance was developed in conjunction with Vac Ex to help reduce the risk of cable strikes during excavation.
The machine effectively ”disturbs” the ground without damaging cables and pipes.
It comes with different shapes of attachment heads to get access where utilities pipes are inaccessible , for example where they are positioned above each other.
“It certainly makes the job easier. It works on the most difficult compacted ground conditions around existing pipes that might be 50 years old or more without the risk of damage,” said Morrison Utility Services health and safety advisor Andy Cox.
The machine uses high velocity air to disperse soil and expose buried utilities pipe work.
Heavily compacted material is displaced with high speed air directed at up to 1,500mph.
As it agitates and displaces porous and semi porous ground conditions it leaves non-porous objects - like utilities, services and tree roots - unaffected.
