Method and device for measuring the weight of a load to be hoisted onto a loading area
First Claim
1. A method for measuring a weight of a load, the method comprising:
- arranging the load on a raised loading surface;
displacing the load with a load lifting device over an edge of the raised loading surface, the load lifting device including driving means and a rigid support driven by the driving means, the rigid support moving the load and being loaded by the load;
measuring, during passage of the load through a predetermined movement position, at least one of an axial force and a lateral force acting in the rigid support of the load lifting device; and
determining a value of at least one of the axial force and the lateral force a weight of the load based on at least one of the axial force and the lateral force.

Abstract
The invention provides a method and a device for measuring the weight of a load, which is displaced with a load lifting device over the edge of a raised loading surface and thus pulled onto the same or pushed down from the same, wherein during this operating process, in a support of the load lifting device loaded by the load, the force currently acting due to the displacement of the load is measured during the passage through a predetermined weighing window and the weight of the load is determined mathematically from the course thereof. Preferably, the load sensor is constructed as a tube which is equipped with two deformation sensors equipped essentially at right angles to one another.

12. A load measuring device comprising:
-
at least one rigid support which at least one rigid support can be moved in such a manner for displacement of a load over an edge of a raised loading surface; a load measuring cell arranged in a support section of the rigid support, for determining a force acting in the support section during displacement of the load; and a computer operatively connected to the load measuring cell, which computer analyzes the force signals of the load measuring cell in a predetermined movement position of the support section to determine the weight of the load. - View Dependent Claims (13, 14, 15, 16, 17, 20)

18. A computer-program product comprising a non-transitory computer-usable medium having computer-readable program code embodied therein, the computer-readable program code adapted to be executed to implement a method comprising:
-
a) determining lateral force acting on a rigid support from signal values of a load measuring cell imbedded in the rigid support that moving a load and being loaded by the load as a function of progressive transport movement of a load lifting device in a measuring window b) calculating from the lateral force the tensile force of the load lifting device and calculating an area value corresponding to a product of the tensile force and paths of the progressive transport movement c) multiplying the area value by a geometry factor for the load lifting device and load which corresponds to a proportionality factor between the area value for a load weight and this load weight, and wherein the computer is further constructed to store this product in a memory assigned to it and/or to display the product as weight of the load. - View Dependent Claims (19)
