SR420II and Other Products Brought to Bauma 2010

In this Bauma 2010, Sany presents four latest pile driving products, namely, SR150, SR280RII, SR420II and SH400C, showcasing its strong capability to develop and manufacture the full series of pile driving machinery products. Among the four types of products, SR420II, the representative model of the second generation of large pile driving machinery which meets the requirement of large diameter and super-deep construction, starts a new era of intelligent pile driving machinery with its supreme quality and outstanding performance.
SR420II features a maximum diameter of 3 meters and a maximum depth of 110 meters in drilling. Apart from the characteristics of large torque, deep drilling hole and more efficient and reliable operating performance, the shining point of this product is the use of intelligent technology, which helps customers reduce difficulty and improve convenience in construction.
SR420II is equipped with three monitors in the cab, which can monitor all operations during hole drilling and all real-time data of the engine, such as rotating speed of the engine, pressure, temperature variation, oil consumption, batter work indicators and so on. The machine can make system fault analysis automatically and give alarms.
SR420II is equipped with GPS and remote expert fault diagnosis module, which can not only monitor all real-time data of the engine, but also perform system fault diagnosis automatically and give alarms, and make remote connection with engineers to guide the operation and coordinate service resources. The GPS and remote expert fault diagnosis module realizes the integration from operation to service support, providing faster and more convenient service to the operation.
At the same time, Sany is the first enterprise in the industry to apply CAN bus technology to rotary drilling rigs. Compared with the conventional centralized control system, the CAN bus control system features simplified wiring, lower failure rate, good anti-interference ability for the transmission of digital signals, high precision transmission and a significant improvement in transmission speed and stability of measurement.
Higher degree of intelligence can also be found in the multi-gear control technology for the drilling head. When the rotary drilling rig is working, the operator can use the standard mode, which allows the load to decide the torque; when it meets rocks, the system can automatically shift to rock-cracking mode, which can protect the drilling head and strengthen the power to crack rocks.
SR420II rotary drilling rig will definitely be popular in the market with its excellent performance and high reliability and intelligence.
the small-sized pile drilling machinery products in the civil engineering market. The SH400C Diaphgram Grab is famed for being highly productive and precise in trough cutting. The SR280RⅡ hard rock driller represents the highest standard in China. Its outstanding performance has been proven in the Second Phase of the Lanzhou - Urumuchi railway project.
