In the transportation method of ground port and space station on Space Elevator Plan, it is very important to grasp and decide the mechanism of driving roller and friction force of the tether for space climber in points of selfweight, transport efficiency and energy consumption. As a driving mechanism of the climber for the space elevator, many types such as confrontation position type, cross position type, others were invented based on the arrangement of the tether and the roller, and various climber models have been prototyped. On the other hand, the weight of climbers considering practicality is expected to be several tens to several hundred tons, and it is necessary to verify whether the climber drive mechanism of about several tens of kilograms developed so far is sufficient. In this report, the development method of practical drive mechanism applying cross positon roller is studied based on design, analysis and performance experiment of drive mechanism assuming relatively high weight climber.
