目前在建筑安装工程和装卸作业中,评价自行式臂架起重机使用能力时,仅仅考虑在起重臂最小长度时它的一些货物高度指标。但是起重机在完成建筑安装工程和装卸作业时,大部分时间使用中等和长的起重臂以及使用塔架一动臂工作装置。因而为客观地评价臂架起重机,在指标系统中应补充在最小幅度时,起重力矩和位的机械功相对于起重臂长度的关系。为定量评价指标的直观性和可能性,这两个关系可用线图表示。
Currently in the construction and installation engineering and loading and unloading operations, the evaluation of the capacity of self-propelled boom cranes, only consider the minimum length of the boom some of its cargo height index. However, most of the time cranes used medium and long booms and tower-boom workstations when completing the construction and installation works and loading and unloading operations. Therefore, in order to objectively evaluate the boom cranes, the indexing system should be supplemented with the relationship between the lifting moment and the mechanical power of the boom with respect to the length of the boom at the minimum amplitude. To quantify the intuition and the possibility of indicators, these two relationships can be represented graphically.
