China Resources Dadong used three records to evaluate the quality and progress of the construction of the 800-ton gantry crane: First, it was completed and delivered on October 18, 2011, and ultra-large lifting equipment was built in just 10 months. The second is to complete the commissioning of the equipment in one month. The third is to complete the hoisting test of the gantry crane for 4 days. The supervisory unit was very surprised that the speed of the 800-ton gantry crane was 40 meters per minute. This may be the fastest of all the super-large gantry cranes. The average gantry crane running at 12 meters per minute is already good.
The Hudong Zhonghua Comprehensive Technology Department introduced several parameters of the 800-ton gantry crane to the participants. The synchronous parameter design requirement is 200 mm, and the measured synchronization reaches several millimeters. After 125% load hoisting, the girders immediately rebound to zero. These two indicators mean that the gantry crane manufacturing is very precise, the beam structure is good, and the welding level is first-class.
