Shanghai Jintai SX40 double wheel milling multi-attack domestic deep tunnel, rail delivery construction market

The construction of domestic rail transit is still in the ascendant, and the development of underground space continues to deepen. It provides a wide application space for construction machinery of Shanghai Jintai two-wheel milling and hydraulic grabbing.

Shanghai Jintai carries the social responsibility of a century-old enterprise and the precipitation of more than sixty years of underground construction equipment manufacturing technology. After ten years of sharpening swords and accumulating a lot of effort, its fourth-generation SX40-A twin-wheel milling machine was launched in May 2017 in Shanghai. A high-rise building, the “Xujiahui Center”, competes with international brands and successfully challenges the 75-meter-deep groove and “joint-sleeve milling” process. It is the first demonstration for the “Chinese-made” slot machine to enter the ultra-deep-connected wall and complex technology mainstream market. Establish a benchmark.

Since then, the Jintai SX40 two-wheel milling has followed suit and won successively Yinchuan central heating through the Yellow River project, Wuhan Dadong Lake sewage treatment system project, Guangzhou Metro Lines 11, 18 and 22, and Shanghai 14th and 15th. Line, Hangzhou Metro Line 5 and other site engineering;

In January 2018, Yinchuan, Ningxia crossed the Yellow River heating project 75 meters deep wall construction site

The standard torque of SX40 two-wheel milling is 2*100KN.m, which is larger than similar products in the market, and has stronger milling ability for rock and soil. In addition, the “large-diameter gas lift reverse circulation” method is used for slag discharge, and the slag discharge efficiency is higher. The slag is more thorough; in actual construction, Jintai SG can be used to grab the upper soft soil in the tank with a wall grab, and then use a two-wheel milling to carry out the milling of the hard formation, and the Jintai SH/SD rotary drilling rig can be used at the same time. After the hole is broken, the slot is then grooved. Through the seamless joint and construction of Jintai's three main products, construction and operating costs can be greatly reduced and construction efficiency can be improved.

Recently, Jintai's two-wheel milling customers have shared the experience of using Shanghai Jintai two-wheel milling in their circle of friends:

“Our company purchased a Jintai SX40 slot machine earlier this year and entered the construction site of the Guangzhou West Metro Line 18 in the Pazhou West area. We have weathered the muddy weathered mudstone. In just two months, we have completed a high-quality 45-piece wall connection. The cumulative time for equipment maintenance and repair is less than 80 hours, and the stability and construction efficiency are amazing..."

“Kintai's service guarantee for the two-wheel milling is even more impressive and impeccable. The team of technical guidance, maintenance and spare parts supply is on-site throughout the entire construction period and on-site, and the application and service seamlessly connect. The intimate service makes the total package Rest assured that customers will feel at ease.”

From product ideas to R&D, from the deep tunnels in the Yangtze River Delta, deep foundation pits to the stations of the Pearl River Delta, and from working wells that cross the Yellow River to anchorage pits across the Yangtze River, Shanghai Jintai has been milling for ten years. After undergoing engineering tests on dozens of deep trenches and hard strata in Shanghai, Hangzhou, Nanjing, Nanchang, Wuhan, Yinchuan, and Guangzhou, the Shanghai Jintai SX40 two-wheel milling gradually matured and became the A/B/C three series products. .
