Transmission Tower Maintenance

Providing safe and innovative solutions for maintenance of transmission towers and similar difficult-to-access structures across New Zealand.

A specialist “Tower Maintenance” division was established in 1994 as part of TBS’ wider range of services. The division has a significant track record in providing safe and innovative solutions to the maintenance of various difficult to access structures, in particular the maintenance of transmission towers across the country.

The work is achieved using fall protected free climbing and rope access techniques, which significantly improves flexibility and provides cost savings to our clients by eliminating the need for complex scaffolding in remote areas. In addition, TBS’ “live line” accreditation means that maintenance can continue without the need for outages.

Specifically, the division provides the following services:

  • High pressure water jetting
  • Abrasive induced water jetting
  • Application of protective coatings
  • Metal spray zinc application
  • Tower erection and construction work
  • Steel replacement and bolt torquing
  • Inspection services (structural and coatings)

Along with these core activities TBS can provide ancillary services such as footings maintenance and grounds work.

Personnel and Training

Our tower maintenance personnel have been extensively trained in the safe disciplines of rope access systems in accordance with AS/NZS 4488 and AS/NZS 1891. These standards are recognised throughout Australia and New Zealand. A number of this team are also ACA qualified coatings inspectors.

Full training records are maintained and monitored for all employees and frequent refresher training and evaluation ensures personnel have all of the competencies required for this high risk work.

The majority of personnel are also Live Line accredited to Transpower New Zealand requirements, qualifying them to work using close approach procedures on live electrical structures.
