Awesome! Weite serves the national key "world's most" project

As one of the national key projects, the construction of the Yangtze River Bridge of Shanghai Tonghua Railway has attracted much attention. The builders of the bridge strive to catch up with the progress and provide a strong guarantee for a good start of the new year. All kinds of cranes are very important in the construction of bridges. Among them, there are the wd120 mast crane and the safety monitoring device of the 75 ton tire type beam transport trolley provided by Yichang Weite Electronic Equipment Co., Ltd. These micro and special products silently protect each lifting operation during the construction of the Hutong Yangtze River Bridge and are a strong backing for improving efficiency and safety.

The Hutong Yangtze River Bridge is the world's largest highway railway dual-purpose cable-stayed bridge and the world's first highway railway dual-purpose bridge with a span of more than kilometers. In order to ensure the safety of girder erection, China Railway Major Bridge Bureau adopts the construction scheme of "scattered erection, continuous erection first and simple support later", that is, the steel beam members are manufactured in the steel beam plant of Wuqiao heavy industry, transported to the lifting dock on the South Bank of the bridge by ships, and hoisted ashore by wd120 mast crane, The 75t tire type beam transport trolley and 13m flat plate truck are transported to the steel beam pre assembly yard for storage and pre assembly. After the pre assembly is completed in the pre assembly yard, they are transported to the pier. Finally, zsl1000 boom tower crane is used for installation in place. The lifting operation is quite frequent in the construction process, and the accuracy and safety requirements of the crane are very high.

In January this year, the micro special electronic technical service engineers came to the bridge construction site again and installed torque limiters and related safety monitoring devices for the five new bridge deck cranes to ensure the safe operation of the bridge deck cranes under the objective conditions of frequent use.

Construction site of 75t deck crane of Hutong Yangtze River Bridge

Based on the large amount of work of Hutong Yangtze River Bridge, frequent use of cranes and complex working conditions, Weite electronics specially arranged technical engineers to conduct comprehensive investigation and inspection on all construction equipment before the construction of this project. After careful investigation and communication, Weite and the construction party have determined a set of best safety protection schemes.

The construction service was in the cold winter. At 7:00 a.m., the micro special engineer boarded the construction ship. The howling cold wind came to his face. The low temperature of minus 2 degrees made a thick layer of white frost on the deck of the ship. It took an hour for the ship to reach under the construction pier.

The purpose of collecting the wind speed is to ensure the safe operation of the crane in the windy environment. However, the installation of the anemometer needs to climb on the A-frame of the crane more than 30 meters away from the river, and the wind speed is tested. In order to prevent the boom from exceeding the limit during retraction, the angle meter, weight sensor and other equipment are also installed. After all installation, the technical engineer carefully conducted comprehensive joint commissioning of the instrument and the crane electric control system.

In the deep winter season, the river is cold and the construction party can't help but give a thumbs up when seeing the rigorous and meticulous service of Weite engineers, who are not afraid of difficulties. "Choosing Weite products is to choose peace of mind and rest assured!"

　

Note: the Hutong Yangtze River Bridge is a key and controlling project of the new Shanghai Tongjiang railway. The main tower of Hutong Yangtze River Bridge is 325 meters high, and the main span of the main channel bridge is 1092 meters. The bridge is divided into two layers. The lower layer is a four Lane Railway and the upper layer is a six lane expressway. It integrates the functions of national railway, intercity railway and expressway. With a total length of about 11.07 kilometers and a total investment of more than 15 billion yuan, the Hutong Yangtze River Bridge is the world's largest highway railway dual-purpose cable-stayed bridge and the world's first highway railway dual-purpose bridge with a span of more than kilometers. The project is expected to be completed in August 2018.
