crane base meaning in Chinese

起重机底脚

The ideas of object - oriented technology and parametric design computation are combined to construct this parametric design system of overhead crane based on object - oriented technology . the corresponding technology are fully used to design and compute partial mechanism of overhead crane . this system makes the deviser ' s design convenient and design period is shortened , and in the meantime work efficiency is improved
基于面向对象技术的起重机参数化设计系统结合面向对象技术和参数化设计计算的思想，充分利用各相关技术，对桥式起重机部分机构进行设计计算，方便设计人员设计，缩短了设计周期，提高了工作效率。
