High pressure air lance makes light work of heavy ground

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.

Easier job

“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.
