在参与我国青藏铁路建设中,山推工程机械股份有限公司专为高原地区施工研制出山推牌TYG220推土机。该产品针对推土机在高原作业发动机出现大量黑烟、动力不足、燃油消耗过大及低温起动性差,关键结构件的低温脆性等弱点,以及高原作业对液压系统密封的特殊要求,在技术上做了相应的改进。
In participating in the construction of China’s Qinghai-Tibet Railway, Shantui Construction Machinery Co., Ltd. designed for the construction of the plateau Hill pushed TYG220 bulldozers. This product is technically designed to meet the special requirements of bulldozer working on the plateau engine such as a large number of black smoke, insufficient power, excessive fuel consumption, poor startability at low temperature, low temperature brittleness of key structural components, and the special requirements of high altitude operation on hydraulic system seals The corresponding improvement.
