Problems solved by technology

The structural and dimensional characteristics of these belts prevent the use of load cells of the type previously described, because not only is the introduction of the belt into the annular groove or groove of the pivot or lug of the load cell impossible, but it is even often The length of the lug itself is wider, so the connection of the flat belt to the load cell is not a stable and durable application, so this type of load cell cannot be used in applications where the load is supported by the flat belt

Abstract

The invention relates to a load cell which is designed to be coupled to flat belt- or similar-type elements for lifting elevators or similar. The inventive cell comprises a cell body (1) and a casing (2) which can be coupled to one another. According to the invention, the solid, metallic cell body supports the corresponding strain gage. In addition, three cylindrical pivots (5) project out from the body, said pivots comprising a smooth outer surface and having a length that is adapted to the width of the lifting belt (9). One of the smaller lateral faces (6a) of the essentially-prism-shaped casing is open such that it can be coupled to the cell body. Furthermore, the upper and lower faces of the casing are provided with opposing openings for the passage of the lifting belt during the operational mounting of the cell.

Description

technical field [0001] The present invention relates to a load cell for elevators etc., which offers new essential features and significant advantages over known and utilized devices of the prior art for the same purpose. [0002] More specifically, the present invention provides improvements in elements of the type used to deform in response to the effect of stresses exerted thereon, and the stresses to be incorporated at predetermined locations on the body of the element. Transmission on the strain gauge to assess the magnitude of the load. The load cell proposed by the present invention is designed for use in elevators and the like, and is adapted to a design pattern that has been specially designed for use in flat suspension parts constructed in the form of belts or the like and having a predetermined width. [0003] The field of application of the invention is included within the field of industry devoted to the manufacture and / or installation of systems for weighing, de...
