Changtai Yangtze River Bridge is located between Taizhou Bridge and Jiangyin Yangtze River Highway Bridge. It is a river crossing channel integrating expressways, intercity railways and first-class highways. The total length of the bridge is 10.03 kilometers. The main channel bridge adopts a cable-stayed bridge with a main span of 1176 meters. The Tianxingzhou special channel bridge and the Lu'anzhou special channel bridge both use steel truss arch bridges with a main span of 388 meters, setting a world record for similar bridges.

The world's first super-large slewing tower crane with a capacity of over 10,000-ton meters was unveiled in the construction of Changtai Yangtze River Bridge. It is mainly used for the construction of the middle and upper columns of the main tower. The tower crane has a rated lifting moment of 12,000 tons and a maximum boom length of 75 meters. Its maximum lifting weight reaches 450 tons and the maximum lifting height is 400 meters, which is equivalent to lifting 300 cars to a height of 130 floors at a time. The equipment uses a wire rope diameter of 55MM and a single rope length of 1700M. The wire rope intelligent detection system independently developed by Weite Company is installed on the super large tower crane with an upper turning of more than 10,000 meters to ensure the safety and health of the wire rope of the super large tower crane.

This sensor is mainly used to quantitatively detect and identify the hidden dangers and damage levels that endanger the safety of use, such as broken wires inside and outside the wire rope, local fatigue, wear and corrosion, and structural deformation. And the influence of the running speed, the detection passing ability is extremely strong.

Weite Brand online monitoring system of steel wire ropes for lifting equipments can realize below functions:

1. Accurately measure the wear of the metal cross-section of the wire rope.

2. Not only can detect the broken wire outside the wire rope, but also can detect the broken wire inside the wire rope.

3. Through the comparison of multiple ropes under the same working condition and the multiple comparisons of the same rope, the deterioration speed and deterioration law of the wire rope can be intuitively grasped.

4. Accurately evaluate the remaining life of the steel wire rope, use the rope scientifically.

5. Prevent wire rope breaking accidents and ensure safe production.
