摘要:
A first adjustable cabin rail guide is moveably attached to a structural member of an elevator cabin. A second adjustable cabin rail guide is similarly moveably attached to a structural member of an elevator cabin. The first and second adjustable cabin rail guides cooperate together to reduce sound and increase operational efficiency. A piece of textile or similar material is attached to a tube forming the friction portion of the guide. The use of textile thereby reduces the sound of the travel upon the rail associated with the inner portion of the elevator cylinder as the cabin transits therein.
