Embodiment Construction

[0022] figure 1 A schematic sectional view illustrating a first embodiment of the compensating weight. Before proceeding further, however, several issues with the preferred embodiments will be discussed.

[0023] The carrier is the specific part of the compensating weight that is carried between the car and the counterweight. Its weights have no load-bearing function, but are mainly used to add mass to compensating weights.

[0024] Preferred embodiments of the first aspect of the present invention provide a compensating weight provided with a carrier. The carrier is usually a chain, or preferably a steel cable, with a flexible sheath, usually plastic, and at least one weight. Weights comprising a mixture of plastics and one or more powdered metal salts and / or metal chalcogenides (especially oxides and sulfides) shall have a mass density of about or greater than 2.3 g / cm 3 . The weighted member can wrap directly around the carrier, or it can be completely free-standing. ...

Abstract

The invention provides a compensation weight for an elevator system, in the form of an extended cable. The compensation weight comprises at least one carrying organ, at least one weighted element, wherein the weighted element contains a mixture of plastic material and at least one of a pulverized metal salt and a pulverized metal chalcogenide with a density about or greater than 2.3 g / cm3, and an extended, flexible sheath. According to another aspect, the invention provides a compensation weight for an elevator system, in the form of a flat cable. It comprises one or more weighted elements, one or more lengthily extended carrying organ, a flexible sheath, and a plurality of hollow spaces encased by said sheath for the reception of the one or more weighted elements and the one or more lengthily extended carrying organ. The at least one carrying organ and at least one weighted element are designed to be separately and respectively in different hollow spaces encased by the sheath. According to still further aspects, the invention is also directed to elevator systems with corresponding compensation weights.

Description

technical field [0001] The present invention relates to the field of elevators, and more particularly to compensating weights for elevator systems, and elevator systems with such compensating weights. Background technique [0002] An elevator system generally includes a car, a counterweight for the car, and also at least one carrying rope. Cables are also secured to the top of each counterweight. The load-carrying cable is drawn from the top of the car and passed around a drive and a diverting pulley. The elevator system in turn has compensating weights to balance the weight of the above-carrying cables, and these compensating weights are fastened to the floor of the car and hang downwards therefrom over multiple cycles. In some cases, each compensating weight is guided towards a guide wheel on the bottom of the wellbore and its respective other end is fixed to the bottom surface of said counterweight. In this way, the pulling force exerted by the drive is compensated at ...
