  • There has been a string of negligent accidents at the seaside, and there is presently a shortage of professional equipment to deal with such accidents. The purpose of this paper is to assess the development of a rescue lift. The critical load of a support pipe, and the stability of the rescue lift, were investigated using structural analysis. Critical-load analysis was used to study the effects of variations in the pipe length and the ratio of the moment of inertia. The total weight of the developed rescue lift is approximately 20.7 kg, and the lift passed the load tests.
