常林股份有限公司早在1998年就针对高原环境,协议选配了上柴6135AK型增压柴油机作为Z50装载机的动力,在四川甘孜等地区（海拔3000m以上）供用户使用,整机情况良好。后又有部分常林Z30和Z50装载机、YZ14压路机在青海格尔木、西藏那曲等高海拔（4600m）地区使用,积累了工程机械使用于高原、高寒地区作特殊改进的经验。近日,通过在海拔4129m的西大滩和海拔3800m的大坂山两个低温起动性能试验检测,机械工业高原工程机械产品质量监督检测中心认为常林Z50高原型装载机各项性能指标（动力性、经济性、热平衡性能、排放性能）达到原基本型低海拔同等水平,属于工程机械高原环境适应性较强的特种机型。
Chang Lin Co., Ltd. as early as 1998 for the plateau environment, the agreement matching diesel 6135AK supercharged diesel engine as a Z50 loader power in Ganzi, Sichuan and other regions (above 3000m) for users to use, the machine is in good condition. After that, some Changlin Z30 and Z50 loaders and YZ14 rollers were used in high-altitude (4600m) areas such as Golmud in Qinghai Province and Nagqu in Tibet, accumulating the experience of using construction machinery for special improvements in plateau and alpine regions. Recently, through the testing of two low-temperature start-up performance tests at the Wadi Beach at an altitude of 4129m and the Dabanshan Mountain at an altitude of 3800m, the Quality Supervision and Inspection Center of Construction Machinery Products of Changzhou Machinery Industry Co., Ltd. considers that the performance indexes of Changlin Z50 Plateau Loader (dynamic, Economy, thermal balance performance, emission performance) to reach the same basic level of low altitude, belongs to the special high adaptability of engineering machinery plateau environment.
