Involved in the project to build the tower crane Sichuan Chengdu another iconic high-end construction complex Intime center.

Intime Center is located in the northern section of the Chengdu Tianfu Avenue Chengdu , the whole project a total of five high-rise towers and mega super high-end commercial podium , the main building height of 56 storeys high 220 meters , set the world 's top luxury Hilton Hotel Waldorf Astoria Hotel , Grade A intelligent office buildings, bringing together dozens of international first-tier luxury brand mall , Intime , high-end serviced apartments Liberte China , China Hyatt House in one, with a total construction area of about 740,000 square meters of super body mass, will build a world -class center of Chengdu city complex Intime , its size and quality are better than Beijing Yintai Center . The project will be completed by December 2015 .

This project, Nakagawa has participated in the construction of two tower crane , tower crane models were C7052 and C7050. C7052 slewing tower crane which is an independent company on the design and manufacture of large , self-elevating tower crane . Maximum lifting capacity 25t, ends hoists 5.2t, maximum working range of 70m. The tower is the chip structure, easy assembly and disassembly , lifting , slewing , luffing , walking , top promotion agencies are using advanced foreign technology , advanced performance and reliability. Walking track machine with a fixed attachment type, the use of three types of climbing , each equipped with a standard section 2m section 2.5m section two, which comes standard with 2.5m mast section Attached maximum lifting height of 262.61m. Institutions with variable frequency drive 120LVF63 lifting mechanism to achieve variable speed, mechanical drive applications mature domestic technology , enabling the air " hover" , to achieve high-speed light load , heavy low-speed , greatly improve work efficiency. 25DVF25A luffing mechanism frequency control system can be started from zero , parking , soft start , soft stop ; variable speed, vector closed-loop control , smooth operation ; wide speed range , improve efficiency , simple structure , low failure rate , easy to maintain. 37RVF ( c rotation ) rotary frequency control system applications stepless frequency control system , can run more smoothly rotating structure more simple and easy to maintain.

Another C7050 tower crane is my independent design and manufacture of large switched on back -up tower crane . Maximum lifting capacity 20t, lifting the ends of 5t, maximum working range of 70m, the largest independent propelled lifting height of 79.7m. The tower is the chip structure, easy assembly and disassembly . The machine has a walking track , fixed , attachment style and the use of other types of climbing . The tower machine uses AC frequency 75VF50R lifting mechanism ; X185K series trolley traction luffing mechanism , simple structure, small size, light weight , smooth transmission , speed performance , flexible and easy to operate, safe, reliable, easy maintenance ; rotating mechanism also using 37RVF ( three rotation ) frequency control system .

River built two tower cranes for construction of 56 layers Yintai Centre Main Waldorf Astoria Hotel , two tower cranes are fixed Attached forms of work, both lifting height will reach 240m or more.
