MENDOZA, Jesús; OTERO, Luis  and  SAFFONT, Marjorie. ANALYSIS OF THE SKEW ANGLE MEASURING MECHANISM IN THE 8007 WELLMAN ORE HANDLING BRIDGE OF FERROMINERA ORINOCO. uct [online]. 2005, vol.9, n.36, pp.207-210. ISSN 1316-4821.

This paper shows how the original designer of the Wellman PA 8007 ore piling bridge of Ferrominera Orinoco measures, in a mechanical way, the skew angle when the wheels of the piler travel over its rails during the phases of iron ore piling. Measuring the skew angle allows to control the forward movement of the 120 m structure. This paper also analyzes a cam lever mechanism with amplification of the detected angle and allows to decipher, in a process of inverse Engineering, the mathematical equations ruling the measurement. The work offers the possibility of making modifications that would help to incorporate new electronic instruments for the control of the driving torque in the two motors of the bridge.
