Application of Intelligent Detection System for Small and Special Steel Wire Rope on 10000t/m Class Tower Crane of Changtai Bridge

September 27, 2022

In the near future，The wire rope intelligent detection system independently developed by Weite has been successfully applied to the world's first super-large rotary Tower Crane of over 10000 tons in the construction project of Changtai Bridge.。

Construction site of Changtai Bridge

Tai Yangtze River Bridge is located between Taizhou Bridge and Jiangyin Yangtze River Highway Bridge.，It is the world's largest span highway and railway cable-stayed bridge under construction.。Is a set of expressway、Intercity railway、First-class highway“Trinity”A passage across the river.。The total length of the bridge is 10.03 kilometers，The main channel bridge is a cable-stayed bridge with a main span of 1176 meters.，Both Tianxingzhou Special Channel Bridge and Lu'anzhou Special Channel Bridge are steel truss arch bridges with a main span of 388 meters.，The world record of similar bridges has been set.。

The world's first super-large Tower Crane with an upper slewing capacity of over 10,000 tons per meter

The world's first super-large Tower Crane with a capacity of over 10000 tons and meters appeared in the construction of Changtai Yangtze River Bridge，It is mainly used for the construction of the middle and upper tower columns of the main tower.。The tower crane has a rated lifting moment of 12000 tons per meter.，Maximum arm length 75 m。Its maximum lifting weight is 450 tons.，Maximum lifting height 400m，It is equivalent to lifting 300 cars to the height of 130 stories at a time.。The equipment uses a wire rope of diameter 55.MM，Single rope length 1700M。The wire rope intelligent detection system independently developed by Weite Company is installed on the super-large tower crane with a rotary capacity of more than 10000 tons per meter.，Guarantee the safety and health of the steel wire rope of the super-large tower crane，Assemble the heavy equipment of a big country，Safe construction of Changtai Yangtze River Bridge。

Installation legend of sensor of steel wire rope intelligent detection system

The sensor is mainly used for quantitatively detecting and judging the internal and external broken wires of the steel wire rope、Local fatigue、Hidden dangers and damage levels that endanger the safety of use, such as wear, corrosion and structural deformation，The non-contact wide distance detection of the wire rope is realized.，Free from oil stain of wire rope、Influence of general wire warping and running speed，Extremely strong detection passing ability。

On-line monitoring system for steel wire rope of small and special lifting equipment can be realized in practical application scenarios.：

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

2.Can not only detect that external broken wire of the steel wire rope,，But also can detect that internal broken wire of the steel wire rope.。

3.Multi-rope comparison under the same working condition、Multiple comparisons of the same rope，Intuitively grasp the deterioration speed and deterioration law of wire rope。

4.Accurately evaluate that residual life of the wire rope，Rope for science。

5.Prevention of wire rope breaking accident，Ensure safe production。
