柳州工程机械厂制造的 Z450型装载机,额定功率为220马力,斗容量为3米~3,适用于土石方工程施工,目前已在平原地区广泛使用。为了进一步考核该机在高原的适应能力,扩大应用范围,最近我们在海拔3500米的高原地带进行了一次试验。为解决在高原地区缺氧、低温、低气压给施工机械带来的难题,我们采取了发动机安装11号增压器的措施,并在低温起动方面作了一些工作。下面概略介绍这次试验情况。
The Z450 loader manufactured by Liuzhou Construction Machinery Factory has a rated power of 220 horsepower and a bucket capacity of 3m~3. It is suitable for construction of earth and stone works and is currently widely used in the plain areas. In order to further evaluate the aircraft’s ability to adapt to the plateau and expand its scope of application, we recently conducted a test at an altitude of 3,500 meters above the plateau. In order to solve the problems caused by lack of oxygen, low temperature, and low atmospheric pressure to the construction machinery in the plateau area, we adopted measures for installing the No. 11 turbocharger on the engine and did some work on low-temperature starting. The following is a brief overview of this test.
