Background
The tower crane (called as tower crane in China) is indispensable mechanical equipment for building ground, and has the functions of lifting objects to different positions and conveying the objects in tons to a higher place from the ground, so that the construction efficiency is greatly improved. Although the operation of utilizing the tower crane to carry out the handling to hanging heavy object is high dangerous work though can not say, nevertheless there is certain risk, does not take care of a bit can lead to serious accident: the method comprises the following steps of overweight risk, sudden gust blow and swing of a hoisting object, unclear hoisting object position when the visual angle of a tower crane operator is blocked, too fast ascending or descending speed and the like.
Therefore, there is a regulation at hong Kong laborer that each tower crane must be equipped with an Automatic hoisting weight Indicator (ASLI/Automatic Safe Load Indicator) inside the tower crane cab. When the weight of the tower crane reaches 90%, the yellow light is flashing, and when the weight of the tower crane reaches 100% or more, the red light is flashing, and the tower crane is automatically braked. On the other hand, it is required to arrange a lifting supervisor on the ground site for supervising whether the lifting object is stable or not and whether the lifting object is overweight or not. Because the Safe hoisting gravity (SWL/Safe hoisting Load) of the tower crane changes along with the moving position of the tower crane, but tower crane operators and ground hoisting supervisors cannot timely and accurately grasp the hoisting weight of the tower crane at each moment, so that whether the tower crane is overweight or not is difficult to judge. Although there is an automatic sling display, there are many times when the automatic sling display has a reaction lag, and when the subject is suspended in the air, the subject is found to be overweight and put back on the ground, which is dangerous and time consuming.
