Elevator design method and elevator

摘要

Problem to be solved: to provide an elevator capable of damaging the main cable using a composite material and its design method.The main cable (6) of the elevator (1) includes a load support (17) made of a composite material having a high strength fiber and a resin.The method of designing the elevator 1 includes a compressive stress design process and a tensile stress design process.The compression stress design step is to set the design parameters so that the maximum compressive stress of the load support portion (17) bent along the sieve, such as the drive sieve (13) and the counterpart (5), does not exceed the compressive strength.The tensile stress design process is the maximum tensile stress of the load support (17) bent along the sieve The process parameter is set so that the sum of the mean stresses applied to the load support portion (17) does not exceed the tensile strength when the load to decelerate the vehicle (7) in the maximum loaded state by the gravitational acceleration is applied to the main cable (6).
