Rigging within the Energy Industry becomes quite complex when building or maintaining Electrical towers and lines. The many variables involved demands extreme caution, skill and experience. Often, the terrain dictates the type of plant and equipment that can be used, but costs and risks are also closely weighed when planning site work.
The most commonly used plant and equipment used are:
- Helicopter
- Crane
- Jib Pole
Helicopter
Helicopters are being used more frequently within the Transmission Arena to build and maintain Power lines. Often rugged terrain inhibits access for Cranes or EWP (Elevated Work Platforms), so a helicopter is a versatile method of accessing areas for lifting or hauling materials, equipment or men. This requires highly specialised rigging. Communication is paramount and all personnel must adhere to strict safety protocol. PRO RIG has had experience with helicopters whilst working on Power lines (both live and de-energised), steel erection work; and installation of High Voltage Air Conditioners on high rise buildings.
With over 20 years experience in NZ and Australia, PRO RIG Crew men appreciate all that is at stake when working with a helicopter by assessing all risk and mitigating any potential threat to themselves, the public or plant.
Helicopter applications are used
- Where access by ground is nil or limited for cranes or jib poles.
- In Tower erection or dismantle.
- To transport personnel.
- In the stringing process where the helicopter is used to pull sections of wire through the pulleys along the line.
- To transport equipment into/from site or straight onto/from the tower.
