Chinese crawler giants unveiled
By Alex Dahm06 June 2011
The end of May was a busy time for Chinese manufacturers Sany and Zoomlion. Both launched range-topping crawler cranes of more than 3,000 tonnes capacity.
Sany's heavy lift twin lattice boom crane is the 3,600 tonne capacity SCC86000TM and Zoomlion's is the 3,200 tonne capacity ZCC3200NP. The SCC86000TM has a maximum load moment rating of 86,000 tonne-metres and the ZCC3200NP is rated at 82,000 tonne-metres, according to the manufacturers. Both are designed to work on the construction of China's nuclear power stations, including the third generation CAP 1400.
The SCC86000TM was developed in Kunshan City in Jiangsu Province and is said by the manufacturer to be the world's largest mobile crane. The manufacturer claims 30 patents on the new crane.
On the ZCC3200NP, in addition to the main crawler tracks, another pair support the rear counterweight wagon. The manufacturer claims more than 20 patents on the new model, including Parallel Closed Control System and Multiple Engine Power Unit. Benefits of the design improve overall stability, anti-rollover capacity and safety, according to the manufacturer.
Look out for more details as they become available.
