Our equipment includes a purpose built rig to work safely under overhead installations, a 4.2 tonne mini excavator & 4 wheel drive support vehicle. The rig is mounted on the back of a single axle, single steer medium rigid truck allowing standard vehicle transit times to and from most sites.

The mini excavator is utilized for trenching in earth wires and light excavation works on-site if required. A 4WD utility is included for transport of supplies, locating sites and crew transport to/from accommodation.
Our service includes picking up plans and supplies from your depot, drilling of earth holes and backfilling holes with wire and earthing compound, and trenching wires back to pole ready for connection.
