In order to obtain new economic growth points and achieve matching with Sany Construction Machinery products, Sany Shanghai Research Institute began to develop a multi-purpose foundation construction special crawler chassis with domestic leading level in 2004 to break the foreign chassis in the basic equipment. Monopoly, in order to obtain the independent intellectual property rights of the chassis, to replace the CAT330C/325VH chassis of the SYR220 rotary drilling rig, and on this basis serialized, modular and versatile design.
SC500 type multi-purpose foundation construction special crawler chassis, referred to as SC500 type chassis, is the main engine of SYR220 rotary drilling rig, and can also be used as the main engine of SYR250 rotary drilling rig. The product is positioned as a leading domestic and international advanced product, making it a benchmark for domestic general crawler chassis.
The product uses an electronically controlled engine that meets Euro II emission standards, uses CANbus bus technology and intelligent instrumentation, and an energy-efficient engine control system. The advanced LUDV hydraulic system is adopted, which can fully meet the requirements of various working conditions of the pile driver; its operating system and control system are specially made for pile foundation equipment, which meets the requirements of various working conditions of the pile driver; the walking device is compared with the Cat330C chassis. The wheelbase has been increased from 4,600 to 5,000. The width of the track has been increased from 4,300 to 4,490. The stability of the whole machine is better than that of the Cat330C chassis.
In addition, the hydraulic system and electrical system of the SC500 tracked chassis are reserved for interface with other working devices, which facilitates the interchange of working devices.
The successful development of the SC500 chassis provides a platform for basic engineering equipment, which can be equipped with large-scale rotary drilling rigs, continuous wall buckets, directional drilling rigs, cranes and other working devices required for basic engineering. It has broadened the space for Sany's development in the field of basic engineering equipment.
The Sany Heavy Industry SC500 crawler universal chassis was successfully developed.
Recently, the SC500 special crawler chassis developed by the Second Research Institute of Sanyi Research Institute was officially launched, which indicates that Sany has independent intellectual property rights and independent research and development capabilities in the advanced chassis for advanced foundation construction.
