Sichuan construction (Group) company adhere to scientific and technological innovation, focus on the use of new technology, new products to develop, to occupy the market. The company launched a new boom type tower crane D90, with its good performance, reliable quality, at present has been successfully exported to Brazil. This machine is our company with products based on the original D80 on manufacturing new technology, innovative design of boomluffing, slewing, self lifting tower crane.

Triangle structure more lightweight jib and Chuan Jian 1.6 meters sectional type standard section by the machine.The end of the lifting 1.5T, maximum take-off weight of 6T, the working range of up to 40 metres, boom angle is 10 ° - 84.4 °, when the boom angle up to 84.4 °, walking the maximum lifting height can reach 69.99 meters. Each mechanism is the use of domestic and foreign advanced technology, reasonable structure, accurate positioning. Special 24BWZ25 luffing mechanism with the machine, the wire wound motor, eddy current brake, speed regulating performance is good, stable operation; and the shoe type brake caliper brake, more safe and reliable operation. The hoisting mechanism is equipped with 33LVF15 and 33RPC15 two kinds of mechanism, where 33LVF15 is the ACvariable frequency lifting mechanism, can fully realize stepless speed regulation, make full use of motor drive, wide speed range, high work efficiency mechanism; while 33RPC15 is used far pole ratio three speed squirrel cage motor, heavy load and low speed, light load speed. Low speed stability is good, has the advantages of simple structure, small volume, light weight, advanced performance. Slewing mechanism of OMD45, the mechanism uses power, advanced electronic technology, electromagnetic coupling and planetary gear stepless speed regulation, large starting torque, smooth operation, advanced performance, reliable.

Luffing jib tower crane has been particularly suitable for building construction in foreign dense city, so the safety of the tower crane is very important. Chuan Jian tower body structure strong, stable, and with a limiter, the brake and thebuffer support device to prevent back tower, a high level of security.

The D90 tower crane has been exported to Brazil, for the construction of Rio de Janeiro City Central Business plaza. It marks the Chuan Jian products market in South America to further enrich and expand.
