1 YWXY º º t rzyywxyhx^y v s k v A Study on the Development of Traction Jig for Bimodal Tram ã äø Ñ ã ä ãã Hee-Taek Yoon *, Young-Kon Park *, Se-Hyun Cho ** ) Abstract The bimodal tram ahead of practical use as a urban transportation means. The bimodal tram can simultaneously satisfy the quality of service and cost through the selective application of the means of infrastructure. If a fault occurs in a car during driving, the traction device which can be quickly and safely towed to the facility is needed. However, there is no suitable and low-cost equipment for traction for bimodal tram. It is not suitable trailer towing equipment because traction time is relatively long and cost is high. In this study, the towing jig which can be attached and removed to the general traction vehicle is developed and verified the usability by vehicle test.
