Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; load-lifting facilities. ^ SUBSTANCE: according to invention, device is furnished with lifted load measuring device in form of cylindrical housing arranged from inner side of check of load-lifting device housing. Housing of load-measuring device accommodates spring with rod terminating in thread and connected to eye plate to which wire rope of hook hanger rope-and-sheave system is fastened. Guide installed in upper part of rod is connected with contact of potentiometer sensor arranged from outer side of cheek of load-lifting device housing. Said sensor is used to transmit electric signal proportional to value of load through supply unit amplifier and comparator device to table arranged on control panel of device. Device is furnished also with disk brake installed on its housing and provided with brake disk on end of shaft of wormwheel of worm pair. ^ EFFECT: improved reliability of device and convenience in operation. ^ 3 cl, 4 dwg
