Pingyang chunde auto parts co., LTD. : classification of glass elevators (ii)

　　Single-arm glass elevator
　　Its structural feature is only one lifting arm, the structure is the simplest, but because lifting arm support point and the relative position between the center of mass of glass often changes, glass lifting will produce tilt, stuck lag, the structure is only applicable to both sides of the glass for the case of parallel straight edge.
　　Double arm glass elevator
　　Its structure is characterized by two lifting arms, according to the arrangement of two arms and divided into parallel arm type elevator and cross arm type elevator, and single arm type glass elevator, double arm type glass elevator itself can ensure the parallel lifting of glass, lifting force is larger. Among them, the cross-arm type glass elevator has a large width of support, so the movement is relatively smooth and is widely used. And the structure of parallel arm type glass elevator is relatively simple and compact, but because the width of support is small, the working load changes greatly, so the motion stability is not as good as the former.
