Transmission Measuring data and control signals are transmitted from the jib head via the measuring cable conductors to the connector box on the drum casing, being picked-up at a multicontact collector ring body, which is connected with a terminal block. Every one of the electric components is incorporated in a fully enclosed aluminium casing of degree of protection IP 65 To the range of application of the mobile crane measuring technique the product spectrum comprises among other things even more measuring components , for instance: - live ring - and rope winch shaft encoders - rope length and cable drum transmitters - uniaxial and biaxial tilt angle transmitters - X/Y-Control transmitters - pedal actuated control transmitters - wind-velocity indicators, indicating units and operator control units

Linear measurement is performed according to the draw wire measuring principle. One makes use of a multiwire measuring cable, which is wound multilayered on a cable reel provided with a pullback spring. A mechanical spindle lead screw nut ensures, that the rope is rewound and unwound exactly layer-by-layer. (Optional layer winder, data on request.) The number of drum revolutions, being proportional to the measured length is determined by a redundant potentiometer system, optionally with resistance, voltage or current output.

measuring drum
The signals representing angle and length of a telescopic crane are important measuring data in a safety and monitoring system of a mobile crane. Determination of such measuring data is performed by means of tilt angle and rope length transmitters Angular measurement The determination of the jib angle is performed by a magnetically damped pendulum system, the swing of which is measured with a redundant high-resolution conductive plastic potentiometer. The output signal is provided in form either of two resistance signals or via the built-in signal converter in form of two current or voltage signals.
