The rollers are easy to deviate in the translocation and need adjustment of position artificially, which increases the auxiliary working time. Comparing tests were carried on the thrust force among the roller supporting system, bearing supporting system and the ball supporting system. Results show that under the same load, the thrust force of the bearing supporting system is smaller than the thrust force of roller supporting system and ball supporting system. Bearing supporting system can reduce the acceleration in the translocation and has excellent directional property. Tests of rolling friction characteristics and compressive capacity of the bearing supporting system were carried out. Results show that the F/N values of the bearing supporting system are reposeful and the ultimate bearing capacity is much higher than the load rating. Bearing supporting system is safe, well operable and suitable for the small weight translocation project.Keywords: ancient buildings translocation; moving system; roller supporting system; characteristics of rolling friction作者簡介：商冬凡，博士研究生，一級注冊結構工程師，教授級高級工程師，Email:13933178581@163.com。參考文獻［1］ANDERS J.
