起重机

This arrangement allows the crane to raise the second boom section beyond the horizontal,compensating for boom deflection when the crane is loaded,and also allowing for greater extension when headroom is limited.

这种设计安排可让起重机推动第二吊杆部分超越水平面补偿吊臂负载时吊杆偏转，也允许在余量有限的情况下作更大的程度扩展。

The crane lifts the wreckage of a helicopter from the Hudson River in New York on Sunday.

At the same time, to make users maintain their system conveniently, we add a human-computer dialogue equipment in the system, users not only can observe all the state of the system but also can deal with the obstacle quickly and efficiently according to the alarm data , which applied by the equipment. It exhibit the humanization design in the new type electric control system of hoist much more.

同时为了用户的操作维护更加方便高效，系统使用了本公司开发的友好人机交互系统，使用户可以观察到系统的所有状态，并可根据该设备提示的报警信息来对系统进行快速有效的故障处理和日常系统维护，更加体现了起重机新型电控系统的人性化设计。

These nonlinear coupled equations are solved by numerical method. First, by means of Simplex Method, searching out the instantaneous velocity of the center of mass of the crane, then all the other dynamic parameters are calculated.

方程组的求解，采用了离散数值解法，首先用直接搜索的单纯形法，解出起重机质心各瞬时的运动速度，进而计算出所有的动力参数。
