Friction drive for amusement fair swing - has wheels located on pivoted mounting frame which is operated by hydraulic cylinder at one end

摘要

A friction drive for a funfair swing has a mounting frame (4) that pivots about a horizontal shaft (3) at its mid-position. The friction wheels (6), driven by a common motor (9), are located at opposite ends of the mounting frame The mounting frame is operated by a cylinder (16) and its movement is controlled by a damper stop (17). The friction drive wheels rotate in opposite directions since they are in contact with the cage of the swing as it moves forward and when it returns. The cylinder (16) ensures that the correct drive wheel (6) is in the active position for the swing motion.
