A new 50-tonne capacity model completes the Tadano Mantis GTC series of five telescopic boom crawler cranes from 35 to 120 tonnes capacity.

The GTC-500, designed and built in the US, lifts 50 tonnes at 2.5m radius and its four-section full-power main boom is 34.7m fully extended. Maximum lifting height with full main boom and fly jib is 51.9m.

Easy transport was a key requirement for the new model and it is designed to be a one-truck crane and comes in at less than 46.72 tonnes.

Versions with standard and extra counterweight packages are available at 7,893kg and 12,791kg. A bi-fold jib is standard, as is a tilting cab to 20 degrees. 

Like the other models in the series, it is designed to operate out of level. The lifting chart at the maximum of four degrees out of level is more than 70 per cent of the chart for level ground and keeps the 50-tonne rating.

It has the Opti-Width function to maximise capacity at any track width setting through 360 degrees. Power is from a 6.7L 260hp straight six-cylinder Cummins QSB6.7 turbo diesel engine.

Full radio remote control is now available across the GTC range. Other options include an auger, work platform and a cold weather package to -40 degrees centigrade.

The order book for the new model opens at the end of 2018 or early in 2019, and deliveries will start later on in 2019.

The GTC-500 joins 35, 60, 80 and 120-tonne capacity models introduced since development started in 2012. First launched was the 120-tonne model at the 2014 ConExpo show in Las Vegas.
