Twinkle Toes

Twinkle Toes demolishing the PricewaterhouseCoopers building in September 2012

Twinkle Toes is the largest excavator in the Southern Hemisphere. It is used in Christchurch to demolish tall buildings following the 2010 and 2011 earthquakes.

History and description

Twinkle Toes' first Christchurch demolition in Liverpool Street in November 2011; note that the articulated arm is not extended

The excavator is based on a 2008 Liebherr 984 that was heavily modified by Kocurek Excavators Ltd for the Birmingham-based demolition Coleman & Company.^[1] It was bought for around NZ$4m^[2] and imported to New Zealand by Auckland-based demolition firm Nikau Contractors, and arrived in the Port of Lyttelton in September 2011.^[3][4][5][6] The tracked excavator weighs 208 tonnes (205 long tons; 229 short tons) and has a maximum reach of 65 metres (213 ft).^[6] When the articulated arm is not extended, the reach is 25 metres (82 ft). The excavator is not suited for demolishing the bottom two storeys of a building.^[5] At full reach, a 2.5 tonnes (2.5 long tons; 2.8 short tons) demolition attachment can be fitted to the hydraulic boom. At 40 metres (130 ft) reach, the machine can handle a 6 tonnes (5.9 long tons; 6.6 short tons) concrete breaker.^[4] The excavator got its nickname following a naming competition on Christchurch radio station More FM.^[4]
