Abstract (en)
Device for controlling automatically the position and the oscillations of a suspended load during its transportation by a lifting device, comprising: - at least one guide means on which moves a translationally moveable carriage, actuated by a motor, to which is hooked a cable (or a rod) from the other end of which is suspended the load to be transported; - at least one position sensor, - an angle sensor, arranged on the carriage, characterised in that it comprises: - a first control loop comprising: . a first comparator (22> . a proportional corrector (23> . a second so-called position control loop, comprising: . a second comparator (20> . a proportional and integral corrector (21> - an adder (24). Application to any transportation of a suspended load requiring special conditions. <IMAGE>
