It absorbs many advanced technology both from China mainland and abroad.2) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be unfer no stress at lifting surface other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting boom.3) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily and effectively, it also lowers the maintenance cost.4)We can offer crane standard sections such as the FO/23B standard sections for customers to choose from.3. Service1.) Providing timely delivery, standby engineers are ready to solve any problems2.) Providing 12 (twelve only)months product warranty period,with ample spare parts3.) Providing work site installation guidance and training of operation and maintenances
