A conveyor belt includes a plurality of identification transponder chips embedded into the belt at spaced intervals. At least one conductive loop is embedded adjacent to and in electromagnetic coupled relationship with each transponder chip. The chip induces an identification signal into its respect

A conveyor belt includes a plurality of identification transponder chips embedded into the belt at spaced intervals. At least one conductive loop is embedded adjacent to and in electromagnetic coupled relationship with each transponder chip. The chip induces an identification signal into its respective conductor loop that is detected by a detector head and is cross-referenced by control circuitry to a specific loop and location on the belt. A second detector head may be mounted and coupled to the loop to monitor loop integrity by detecting or failing to detect the responsive identification signal from each transducer. Embedded transducer elements may further be utilized for wear rate monitoring and identification of exact locations in the belt.

The load carrying means according to claim 1 wherein said resilient element is one of a bending girder, a bending element and a torsion rod. 3. The load carrying means according to claim 1 wherein said resilient element is one of said bending girder and said a bending element, end said sensor means is one of a strain gauge sensor, a piezoelectric sensor and a capacitive sensor. 4. The load carrying means according to claim 1 wherein said resilient element is said torsion rod and said sensor means is a torque sensor. 5. The load carrying means according to claim 1 wherein the load-dependent forces act on said resilient element through both of said cable rollers. 6. The load carrying means according to claim 1, wherein the load-dependent forces act on said resilient element only through said at least one cable roller. 7. The load carrying means according to claim 1 wherein said support construction is adapted to be fastened to a carrier frame for the elevator car. 8. The load carrying means according to claim 1 including a base frame for attachment to a bottom of the elevator car and wherein said support construction is attached to said base frame by resilient isolating elements. 9. A load carrying means for cable elevators comprising: a base frame adapted to be attached to an underside of an elevator car; a support construction including at least one resilient element; a resilient isolating means attaching said support construction to an underside of said base frame; a pair of cable rollers positioned below said support construction, at least one of said cable rollers being rotatably attached to said resilient element; and a sensor means mounted on said support construction for sensing one of bending and twisting of said resilient element whereby when said base frame is attached to the underside of the elevator car and said cable rollers are engaged by a support cable Supporting the elevator car, said resilient element is one of bent and twisted by load-dependent cable forces acting on said resilient element through said at least one cable roller. 10. The load carrying means according to claim 9 wherein said resilient element is one of a bending girder, a bending element and a torsion rod. 11. A load carrying means for cable elevators with integrated load measuring equipment comprising: a support construction adapted to be attached to an underside of an elevator car and including at least one resilient element; a pair of cable rollers positioned below said support construction and being rotatably attached to said resilient element; and a sensor means mounted on said support construction for sensing one of bending and twisting of said resilient element whereby when said support construction is attached to the underside of the elevator car and said cable rollers are engaged by a support cable supporting the elevator car, said resilient element is one of bent and twisted by load-dependent cable forces acting on said resilient element through said cable rollers. 12. The load carrying means according to claim 11 wherein said support construction is formed as an inverted U-profile having said resilient element as a horizontal bending girder connected between two downwardly extending cable roller supports, each of the cable rollers being rotatably mounted at an end of an associated one of said cable roller supports, whereby the cable forces act on said support construction so as to cause a load-depending bending in said bending girder. 13. The load carrying means according to claim 12 wherein said sensor means is mounted on said bending girder.
