Abstract

PURPOSE: To arbitrarily turn a bucket and to retain the turning angle of the bucket by simple mechanism by horizontally displacing sheave group on a main trolley and sheave group on an auxiliary trolley via ropes guided from a drive unit externally installed of the respective trolleys.
CONSTITUTION: After turning driving ropes 20, 20' are engaged from both ends 19, 19' of an equalizer beam 27 on a main trolley 9 to guide drums 22, 22' on respective auxiliary trolleys 10, they are coupled with both ends of a drive unit 23 on a girder 11. In order to turn a tucket 18, sheave group E are turned by the tension and loosening of the ropes 20, 20' upon driving of the drive unit 23. Since the bucket 18 is, however, inclined at turning position, the drums 22, 22' are rotated to move the sheave group F through differential reduction gear 42 and shaft 35 by half in the same direction as the sheave group E to thereby correct the lengths of the respective ropes after the group E when the ropes 20, 20' are drawn or loosened in movements.
