1. Anordning för indikering av slack pa ett rep för användning i gruvvinschanordningar med en lyftkorg upphängd i ett över ett huvudhjul fört rep, och till vilka hör en vinschmaskin vilken stoppas med elektriska vinschmaskinsstoppsignaler som bildas av elektriska kretsanordningar (10, 12, 14, 16, 18, 24, 26, 28) vilka kretsanordningar uppdagar slack pa repet, varvid denna anordning för indikering av slack pa ett rep omfattar anordningar (6, 8) för övervakning av repbelastningen och för bildande av elektriska signaler, samt anordningar (36, 38, 40 , 42, 44, 46, 48, 50) för bevakning av repets längd och bildande av elektriska signaler sä, att belastningssignalernas värde kan kompenseras med repets vikt, kännetecknad därav, att de elektiska kretsanordningarna (10, 12, 14, 16, 18, 24, 26, 28) är anordnade att mottaga belastningssignaler och bilda en stoppsignal för vinschmaskinen, da belast-ningssignalerna faller under ett pa förhand bestämt värde.
2. Anordning för indikering av slack pa ett rep enligt patentkravet 1, kännetecknad därav, att bevakningsanordningen (6, 8) för repbelastningen omfattar anordningar vilka är anordnade att bevaka den kraft, som repet förorsakar i huvudhjulet.
3. Anordning för indikering av slack pa ett rep enligt patentkravet 2, kännetecknad därav, att bevakningsanordningen (6, 8) för repbelastningen Mr anordnad att följa den kraft, som uppträder mellan ett sparhjul, över vilket repet är fört, och atminstone ett stöd för sparhjulet.
4. Anordning för indikering av slack pa ett rep enligt patentkravet 1, kännetecknad därav, att anordningarna (36, 38, 40, 42, 44, 46, 48, 50) för
