Heavy lift specialist Hiap Tong supplied Liebherr LTM 11200-9.1 and LTM 1500-8.1 wheeled telescopic cranes for the installation of wind turbines on the Mongolian steppes.
The 1,200 and 500 tonne capacity cranes were used by the Hiap Tong Corporation joint-venture partner in Northern China, Inner Mongolia Hiap Tong An Da Heavy Lift Co Ltd (IMHTAD). The cranes erected 90 and 70 metre tall turbines near Wulan Chabu, Inner Mongolia. Each of the Chinese Sinoval SR series turbines has a tower weighing 150 tonnes and were erected in four or five days depending on the weather. In addition to erection, the cranes were used for repairs on five turbines installed earlier.
Adding the two new cranes takes the total to 15 Liebherrs in the Hiap Tong fleet of 114 units. "Our Liebherr cranes are at the heavier end of the range," said Patrick Ng, Hiap Tong executive director. "We keep our fleet as young as is practical, generally renewing our units after about nine years," Ng continued.
Around 40% of Hiap Tong's business comes from the marine industry, 40% from petrochemical and 20% from construction. Established in Singapore in 1978, Hiap Tong Corporate offers equipment for lifting and haulage services. The group focuses on the leasing of cranes and haulage equipment in Singapore and northern China. It also trades equipment in India, Indonesia, Malaysia and the Middle East.
