First Comansa towers sold in India
By Euan Youdale17 January 2011
Linden Comansa group has sold its first towers cranes to India for work on power-related projects.
Comansa Jie supervised the erection and commissioning of the four 21CJ290-18t cranes for BGR Energy Systems Ltd., in India with the support of its agent in India ECEL.
Manufactured in Hangzhou, China, by the Comansa subsidiary, all the cranes will be used on two power plant projects.
Two of the 18 tonne capacity flat top tower cranes have been erected at the Kalisindh plant, in Rajasthan, north east India, near the Pakistan border. A third has been erected at the Marwa plant, in Chhattisgarh, central India. At the end of February Comansa Jie finished the erection and commissioning of the fourth crane at the Marwa plant. The plants will cost some US$1.7 billion to build.
They will all work on the construction of cooling towers. The two 200 m high towers at the Kalisindh plant will both have a base diameter of 142 m, making them the biggest in India, said Comansa. The Marwa-based tower will have a 115 m base diameter and be 170 m tall.
The 21CJ290-18t has a dismantling system, designed by Comansa, which allows the jib sections and some counterweight blocks to be jacked down inside the cooling tower. Once the jib has been shortened, the tower sections of the crane will be dismantled with a hacking cage, also inside the cooling tower.
