Potain at Duge Beipanjiang Bridge in China
The cranes are having to contend with tough operating conditions
Potain tower cranes are being used to construct a major cable-stayed bridge in China. The conditions are tough and feature high winds and monsoon conditions, with the cranes working at an altitude of 1,500m above sea level in a mountain range in southern China to build the Duge Beipanjiang Bridge, which will Span 720m when it is complete

The job is requiring six Potain tower cranes in Total during the course of the US$92.75 million (570 million RMB) project. Two cranes have been erected at the job site and are working on the bridge’s main pylons on either side of the Beipanjiang Canyon. The four other Potain cranes are due to be installed over the coming months and all of the cranes will work at the site for four years. The cranes will climb to final working heights of up to 290m to complete the project.

Potain at Duge Beipanjiang Bridge
Liupanshui Shengsheng Construction Equipment Leasing owns the Potain MCT 370 cranes. The Potain cranes at the Duge Beipanjiang Bridge project were transported more than 2,000km from Potain’s facility in Zhangjiagang, Jiangsu province, to the job site, much of it along narrow and winding roads. Now, the equipment has to cope with the monsoon climate, which fluctuates from freezing temperatures, high winds and snow through to drought and dust storms. Operations for the cranes run 14 hours a day, every day, with both required to lift construction materials and equipment in loads of up to 20tonnes. The bridge’s pylons will measure 269m and 247m in height, so to contend with such high lifting heights the cranes are fitted with winches that enable them to lift 17tonne loads up to 270m high.

The Potain MCT 370 is built at Potain’s facility in Zhangjiagang, Jiangsu province, China. The maximum jib length is 75m while 2.7tonnes can be lifted at the jib end. The MCT 370 has a maximum free-standing height of more than 64m.

Duge Beipanjiang Bridge will Span across the Beipanjiang Canyon at the boundary of Yunnan Province and Guizhou Province. Total length for the bridge will be 1,340m and having started in 2012, work is expected to complete in 2016. Main contractor in charge of the build is Second Harbour Engineering Company, a subsidiary of the Fortune 500-listed China Communications Construction Company. In addition to the bridge the company is building a 3.4km section of the Bidu Expressway, which includes three tunnels and seven bridges.
