Basic Introduction The elevator (or lift in the Commonwealth excluding Canada) is a type of vertical transport equipment that efficiently moves people or goods between floors (levels,decks) of a building, vessel or other structure. Installed in the engine room motors and gearboxes, brakes and other components of traction machine, is the traction drive power. Bucket Elevator is equipment transfer material from one place to another place. The basic idea is that a fan system floods the shaft with ambient air during a fire, thereby preventing smoke from entering the elevator shaft by creating positive pressure differences across all elevator doors.
