Abstract: The invention relates to a belt retention guide for retaining the position of a belt having beads along its peripheral edge. The belt retention guide comprises a first roller, a movable portion, and a fixing portion. The first roller engages with the beads and retains the position of the beads. The movable portion supports the first roller and the fixing portion engages with the movable portion. The beads are pinched between the first roller and the fixing portion, thereby retaining the position of the belt. The movable portion is configured to be movable between a fixed position where the first roller engages with the beads to pinch them, and a released position where the first roller is separated from the beads to release them. The movable portion is secured in the fixed position by insertion of a stop member through or between the movable portion and the fixing portion.

Abstract: Ends 14A and 14B of a belt body 14 are detachably joined together by a first slide fastener 21 so that a curved conveyor belt 13 forms an endless loop. The outer circumferential edge of the curved conveyor belt 13 can be separated as a detachable belt edge 15. A bead 26 extending along the outer circumferential edge of the belt is mounted to the detachable belt edge 15. The detachable belt edge 15 is detachably attached to the belt body 14 by a second slide fastener 22.

Abstract: A belt device for driving an elevator is provided, the rest retaining capability of which is improved in order to retain the stopped state of an elevator cage if oil or water adheres to between a belt and a pulley. In the belt device for driving an elevator in which a belt 4 is stretched over a plurality of pulleys 1, 2, and 3, and the belt 4 is rotated by the rotations of the pulleys 1, 2, and 3, wherein the coefficient of friction of a contact surface with at least a driving pulley in the belt 4 is set to 0.6 to 3.0, and the contact surface is constructed of a rubber having a hardness (IRHD) of 65 to 95, and a wear resistance of 5 to 300 mm3 in Taber wear (ISO547-1-1999, under conditions: a wear ring of H18; a load of 1 kg; and 1000 rpm).

Abstract: An elevator drive belt, while applying a friction force thereto, drives an elevator rope which links an elevator cage and a counterweight together. A rubber hardness of the belt ranges from about 50 to 90 degrees of JIS-A hardness so as to suppress creep slip due to a shearing strain while the elevator is in operation. Even if the elevator cage and the counterweight are reduced in weight and the friction force to be applied to the elevator rope decreases due to the weight reduction, a friction force onto the elevator rope from the elevator drive belt compensates and guarantees a drive force of the elevator.
