Abstract

919,591. Earth - excavating machines. HAGANES, M. Sept. 29, 1961, No. 35255/61. Class 68 (1). [Also in Group XXX] An hydraulic ram 1 for slewing a crane is connected to a collar 10 on the crane pillar by a link 8 which is connected also to a link 7 carried by a fixed pivot 11. When the crane has been slewed through 180 degrees, the link 8 may be disconnected from the collar 10 and connected to a different hole 12 so that slewing may be continued.
