After the completion of the Three Gorges Project has attracted worldwide attention because of the dam resulted in the closure of the dam , forming the largest 113 meters downstream water levels drop . Passing to solve the problem of the ship, the Three Gorges Project has built a double five locks in 2003 , is currently under construction line vertical ship lift .

Ship lift is built on navigable rivers to overcome the water level drop , for the ship ride the elevator or escalator . The vertical ship lift is built vertically down through the ship carrying the boat hand, in order to overcome the water level drop . Vertical ship lift suitable for larger water level drop of the occasion , faster, less power , is the large ship lift our stabling commonly used form.

The ship lift in the building construction , the use of the river and the construction of two sets of C7030 2 F0/23B tower crane for ship lift dam pouring , steel, template hoisting operations. Another four Chuan Jian SC series construction hoist for loading transportation and construction items of construction workers. Which C7030 tower crane 274 tons maximum lifting torque meters , maximum weight 16t, ends hoists 3t, working range 70 meters , two tower cranes are fixed attachment style , attached to the dam ship lift , attachment height of 185 meters . F0/23B tower crane standard height walking type, maximum torque of 132 tons lifting meters and a maximum lifting capacity 10t, ends hoist 2.3t, working range of 50 meters. The four construction lifts are SC200/200W, using the German advanced SEW construction elevator dedicated motor reducer , its single cage power of 3 × 11kW, and the use of frequency control , PLC logic , through the acquisition of various operations running signal integrated logic analysis , so that the lift operation more stable , secure and reliable. Cage size is 3 × 1.5 × 2.7 m , easy transport bulky materials . Chuan lifts are on the cage , standard section , with a lot of walls and other structures were optimized design , making the structure more reasonable, more secure and reliable machine .

To "SCM" as a symbol of construction machinery products are widely applied for many years in a variety of national key construction projects , such as the Three Gorges water conservancy , water diversion project , the Daya Bay Nuclear Power Engineering , Hangzhou Bay Bridge project , the National Stadium " Bird's Nest" National Engineering and Grand Theatre and other projects . Meanwhile SCM is internationally high reputation , products throughout Southeast Asia , Central Asia , the Middle East , Latin America , Eastern Europe and Africa , has been widely praised.
