Safety control system - Import export

The combination of crane control and wireless control concept creates the link between an operator and a crane and thus makes optimum load handling a tangible experience. Absolutely safe operation of a crane or a system of several cranes must always be guaranteed – safety for the crane operator as well as for the transported goods and surrounding infrastructure. The smart Demag SafeControl system enables independent and continuous monitoring of a crane on the basis of a largely redundant control concept to bring the system to a standstill independently if any irregularities occur. Furthermore, dangerous conditions can be identified and prevented in advance. The crane operator can concentrate fully on his/her work at all times thanks to the safety control system. A crane can be conveniently and intuitively controlled by radio, which is also very efficient. The safety control system combined with radio control can ensure gentle handling and precise positioning of loads.

Tilt angle values of a platform stand for important measuring data as a part of the safety and control system of machinery. Angular measurement is, for instance for equipment levelling, performed in such cases by means of dual axis pendulum systems. Transducers of that type contain inside a robust splash-proof aluminium case of protection degree IP 65 to IP 68 oil-damped pendulum systems, the tilt angle dependant swing of which is measured, depending on the application, either by a potentiometric, non-contact inductive or an optoelectronic angular encoder. For measurements relevant to safety, the pendulum swing per axis is detected with redundancy i.e. by means of two mechanically and electrically independent pendulum systems. The output signal, representing the tilt angles, is provided either in form of an analog resistance, current or voltage variation or as a digital signal - with interface bus - as well.
