<p>PURPOSE:To simplify the structure and enhance the workability by supporting both ends of the roller shaft of a guide roller by bearing units, providing side rollers on both the ends thereof in a position higher than the guide roller diameter to regulate the transverse displacement of a rope. CONSTITUTION:A guide roller 7 formed of an elastic body such as urethane rubber is fixed to a roller shaft 6, and both ends of the roller shaft 6 are supported by bearing units 8 so as to be rotatable. The bearing units 8 are fixed to a support plate 9 by bolts, and the support plate 9 is fixed to a mounting bracket 12 by bolts 10 and nuts 11. Further, side rollers 13 formed of an elastic body such as urethane rubber are disposed in positions slightly higher than the roller diameter of the guide roller 7 and with a space broader than the whole width of a main rope. The side rollers 13 are rotatably mounted by shafts 14, and the shafts 14 are fixed to the support plate 9 by welding and the like. On both the ends of the support plate 9, protective plates 15 having inclined surfaces are provided.</p> |
