The invention relates to a folding arm crane, in particular to a folding arm crane used for installing an air conditioner outdoor unit. When the air conditioner outdoor unit is installed, a worker needs to stand on a window to lift and put down the air conditioner outdoor unit, and at the moment, the falling risk is large. In order to solve the problem, the invention provides the folding arm crane, and aims to provide an installation method which does not need to place a worker outdoors. In order to achieve the purpose, the folding arm crane is achieved in the mode that one end of the folding arm crane is fixed in a wall outlet hole of an air conditioner, the other end of the folding arm crane lifts an air conditioner outdoor unit, the folding arm crane is twisted to send the air conditioner outdoor unit and a support out of a window together, a screw hole in the outdoor unit support is aligned with an expansion screw on a wall, and then the air conditioner outdoor unit is lifted. After a worker bends down to fasten the expansion screw, the air conditioner outdoor unit can be installed. Due to the fact that the air conditioner outdoor unit is installed outdoors in a hoisting mode, workers complete the whole installation process indoors, and the falling risk does not exist.
本发明涉及一种折臂吊,尤其涉及一种空调外机安装使用的折臂吊。当安装空调外机时,需要工人站在窗口提起并放下空调外机,此时都有很大的坠落风险。为了解决上述问题,本发明提供的折臂吊,其目的在于提供一种不需要将工人置身与室外的安装方法。为实现上述目的,本发明提供的折臂吊是这样实现的:将折臂吊的一端固定在空调的出墙孔内,另一端吊起空调外机,扭动折臂吊将空调外机连同支架一并送出窗口,使外机支架上的螺丝孔与墙体上的膨胀螺丝对正,工人俯身将膨胀螺紧固后,即可完成空调外机的安装。由于本发明采用的是以吊装形式将空调外机安装到室外,整个安装过程中工人都在室内完成,无坠落风险。
