CH/CS Cone Crusher
(1) CH/CS Cone Crusher is a single cylinder hydraulic structure. The equipment is designed according to heavy-duty working conditions. The main shaft is supported at the upper and lower points, and the stress conditions are good.
(2) The constant crushing chamber (CLP) design keeps the feeding and production capacity constant during the liner wear cycle, significantly reducing the operating cost.
(3) Up to ten kinds of cavity shape changes and up to four kinds of eccentricities can be set for an eccentric sleeve bushing, which greatly enhances the flexibility and adaptability of the equipment.
(4) Equipped with intelligent ore outlet adjustment system ASRI, the performance of the crusher can be maximized.
(5) Advanced liner wear monitoring and automatic compensation functions, operation data record query functions, and convenient network communication functions can significantly improve the maintenance level of equipment and optimize the coordination and control with other equipment in the system.
(6) Compared with CH type, CS type crushing chamber is higher and steeper, with larger feed inlet and larger carrying capacity. It is suitable for secondary crushing when the feed particle size is large. Its lower frame is interchangeable with CH crusher of the same specification.

China Railway Qinghai-Tibet Railway JQ140G bridge erecting machine fills the domestic gap
On June 26, 2006, the JQ140G bridge erector, a groundbreaking piece of equipment independently designed and manufactured by Wuhan China Railway Engineering Machinery Plant under China Railway Engineering Corporation, successfully passed the technical achievement review organized by the headquarters. This marked a significant milestone as it filled the domestic gap in high-altitude bridge erection technology and achieved a leading position within the country. The evaluation committee was composed of senior researchers and professors from various fields, including engineering machinery, railway construction, locomotive design, and structural engineering. They carefully reviewed the comprehensive reports on the durable beam transport system for the Qinghai-Tibet Railway, watched live video footage of the bridge construction process using the JQ140G system, and examined all relevant data. After thorough discussions, the experts concluded that the JQ140G bridge erector was specifically developed for the challenging conditions of the Qinghai-Tibet Railway. The technical documentation provided was complete, the data reliable, and the research outcomes rich in content, meeting all assessment criteria. As a result, the committee unanimously approved the "Opinions on the Development and Evaluation of the Qinghai-Tibet Railway JQ140G Bridge Erection Machine."
Engineered to operate in the extreme environment of the Qinghai-Tibet Plateau, the JQ140G incorporates advanced features such as plateau-grade diesel engines, dual-pump air supply systems, large-capacity air cylinders, aviation-grade hydraulic oil, heating devices, and lightning protection systems for mobile equipment. Its structural design is both rational and compact, ensuring reliable performance under harsh high-altitude conditions. It meets the demanding requirements for erecting durable beams along the Qinghai-Tibet Railway. The lifting mechanism features an independently developed automatic rope device, filling a critical gap in domestic railway bridge erector technology.
Additionally, the JQ140G can be disassembled and transported over long distances via the Qinghai-Tibet Highway, making it highly adaptable to the unique construction needs of the railway. This capability holds great significance for future transportation of bridge erection machines. In the Qingliang-Tibet Railway project, the JQ140G was used to construct 2116 beam holes, including 140 holes in a 20-inch continuous 23-inch-long safety frame beam, setting national records with 12 instances of 32-meter beam erection and 13 cases of 24-meter beam construction.
