Abstract

Oppfinnelsen vedrører en kranbom med en om en vertikal svingeakse dreibart på et fundament (3) anordnet hovedbom (2) som i en ende har en ved hjelp av et første stillelement (8) bevegbar hjelpebom (6) og i den andre enden har minst en ved hjelp av et andre stillelement (l 1) relativt hovedbommen (2) svingbar motvekt (9). For utligning av hjelpebommens (6) stillingsendringer foreligger det en innretning (12) som forbinder det første og .indre stillelement (8,11), for derved å muliggjøre en stillingsendring av motvekten. For bedre energiutnyttelse og større standsikkerhet ved større utraginger av kranen foreslås det å benytte to motvekter (9a,9b) som er skråstilt relativt hverandre med en spredningsvinkel (a) og er anordnet på hver sin side av et vertikalplan som går gjennom hovedbommens (2) lengdeakse. Disse to motvekter (9a,9b) kan svinges innbyrdes synkront ved hjelp av det andre stillelement (11).
