Potain crane endures earthquake in New Zealand and immediately returns to work
The 14 t capacity MR 225 A was constructing a hotel in the nation’s capital when the 20 second tremor struck. Windows were smashed buildings damaged and part of the city’s port fell into the sea.
Tidd Ross Todd Manitowoc’s New Zealand dealer supplied the crane to main contractor Dominion Constructors. The Auckland-based construction company was delighted that the potentially lethal quake caused such little damage as Grant Thomas senior project manager at Dominion explains:
“A 6.5 quake is no small matter ” he says. “While an earthquake is not part of the usual crane testing process we can now vouch for the stability and strength of Potain tower cranes even in such extreme conditions.”
The MR 225 A is converting an old office block into a 15 story luxury hotel in the city’s downtown area. The crane which is anchored to the building at a height of 26 m was erected in March 2013 and will remain at the $35-million project until early 2014.
Rigged with a full 55 m jib and at a working height of 52 m the crane is stripping the office block to its basic skeleton and deconstructing the top level of the building. After which it will add six more floors lifting a variety of general construction materials including concrete rebar and glass.
Thankfully the crane was not in use at the time of the earthquake which struck at 5:09 pm on Sunday July 21. It was the strongest quake to hit the region since 1942. Train services were shut and dozens of buildings were damaged but the financial cost was minimal despite the earthquake’s power.
Robert Carden engineering director at Tidd Ross Todd adds:
“We represent the world’s best brands that are made to the highest quality standards and we supply these cranes using the most skilled people. This earthquake proves our business model works – and we are just thankful that no one was badly hurt.”
