The Westconnex Joint Venture, comprising CPB, Dragados and Samsung C&T, recently purchased two Hitachi Sumitomo Crawler Cranes for ongoing use at the project’s Arncliffe staging site.

HLD developed the technical lift study that determined the 275 tonne, Japanese made crawler cranes were suitable for the site's requirements. The study determined that the cranes could lift up to three-tones around a radius of nearly 45 metres.

The Arncliffe staging site is now being used to deploy tunnelling machines towards Bexley and St Peters, through two tunnel shafts that penetrate 65 metres below ground.

Westconnex is the largest transport infrastructure project in Sydney since the Harbour Bridge was completed in 1932. It will eventually connect two of Sydney's main motorways – the M4 in western Sydney and the M5 in south-western Sydney and will provide vital links to Sydney's main international gateways at Sydney Airport and Port Botany.
