McMahon's demolition shear ready for action

Australian construction services company McMahon Services has combined a 400 t Komatsu excavator with a demolition shear that can pierce through 80 mm (3 in) high grade steel with a cutting force of 5,500 psi (380 bar).

The result is an A$ 5 million (US$3.77 million) machine.

Commissioning took place at McMahon’s Adelaide facility, with a team of specialist mechanical engineers and hydraulic experts spending two months getting the machine ready for its first demolition job at a major iron ore facility in Port Headland, Western Australia.

After that, it will return to South Australia and continue its work at the Port Augusta Power Station, where it is earmarked for mechanical demolition, scrap processing and recycling work.

McMahon said the addition of this machine to its fleet of high performance demolition excavators consolidates its position as one of Australia’s leading demolition companies.
