Benefits of technology

The present invention provides an improved lifting machine that uses a small motor instead of a large pulley system to move the cage. It achieves this by using a special type of belt called a tension member that helps it work better with its own weight.

Problems solved by technology

The technical problem addressed in this patent is how to provide a more efficient and effective way to prevent the rope from slippaging during operation of a hoist system used in lifts, particularly in smaller buildings.

Embodiment Construction

[0060]Embodiments of the invention will be described below in detail with reference to the drawings. First, a description will be given of an elevator apparatus wherein a drive device of the straight drive type is used as a drive device for driving ropes, serving as tension members, by frictional contact therewith, i.e., by pressing a straight region of each rope. Subsequently, a description will be given of an elevator apparatus wherein a drive device of the circular-arc drive type is used for driving ropes as reeved around a sheave by pressing a circular-arc region of each rope against the sheave.

Apparatus Comprising Drive Device of Straight Drive Type

[0061]FIG. 1 shows the basic construction of an elevator apparatus of the invention wherein a drive device of the straight drive type is used. As illustrated, a rope 3 extends as reeved around a plurality of sheaves, such as a sheave 42 provided at a specified position within a path of movement of the elevator and sheaves 4, 43 attached

Abstract

The invention provides an elevator apparatus comprising a cage 1 disposed inside a path of upward or downward movement vertically movably, a counterweight 2 vertically movable with the upward or downward movement of the cage 1, and a lift drive mechanism for driving the cage 1 upward or downward. The drive mechanism comprises a sheave 42 disposed inside the path, ropes 3 extending along a route around the sheave 42, and a drive device 5 in engagement with the ropes 3. The drive device 5 comprises a belt transmission provided alongside the ropes 3 and revolvingly movable along the rope extension route, a mechanism for pressing a belt surface of the belt transmission into contact with the ropes 3, and a drive motor for driving the belt transmission. The cage can be driven upward or downward without using any traction sheave, while the cage can be reduced in weight.
