Abstract

Inventia se refera la un dispozitiv de protectie pentru limitatorul electronic de moment al macaralelor cu brat telescopic care previne supraîncarcarea macaralelor prin aceea ca pentru o anumita depasire a sarcinii nominale blocheaza acele comenzi care permit cresterea momentului. Dispozitivul conform inventiei determina valorile inventiei determina valorile numerice ale tensiunii prescrise printr-un calcul de interpolare functie de perechile de valori lungime respectiv înclinate brat convetite sub forma numeric cu tensiunea dependenta de sarcina la cîrlig dupa ce aceasta a fost convertita în prealabil sub forma numerica atît operatiile de calcul cît si compararea fiind efectuate de un microsistem de calcul.The invention relates to a protective device for the electronic torque limiter of telescopic arm cranes which prevents the overloading of the cranes by the fact that for a certain overload of the nominal load it blocks the commands that allow the moment increase. The device according to the invention determines the values of the invention to determine the numerical values of the prescribed voltage by an interpolation calculation based on the pairs of lengthwise values respectively the inclined arm convected in numerical form with the load-dependent tension at the hook after it has been pre-converted in numerical form computational operations and comparing are performed by a computing microsystem.
