Farra's High-Riser climbing work platform encompasses all sides of a building, two storeys high, and ''climbs'' wires suspended from multiple davits on the building's roof, using a combination of a hydraulic ram and specialist wedging system, which locks on to the wire cables.

Farra chief executive Gareth Evans said while marketing had not been done on the High-Riser, there was already interest across New Zealand and Australia.

''We've had very positive responses. Our markets will be the Middle East, Australia, the United Kingdom and here,'' Mr Evans said.
