Abstract:
PROBLEM TO BE SOLVED: To reduce the weight of the vertical lifting part of an unloader and easily detect and control the turning direction thereof by providing an L-shaped bucket chain elevator having a chain line which can be twisted.
SOLUTION: A drive sprocket 17 and a guide sprocket 18 of a bucket chain elevator 16 are disposed in an upper column 11 so that a bucket is turned upside down and moved down for a tilting boom. The connection side to the tilting boom 4 of a vertical lifting part 10 of a lower column 12 is a down-side and guide sprockets 19, 20, 21 are mounted to the lower end of the lower column 12 so that the down-side is parallel to the up-side thereof. A chain which can be twisted and is provided with buckets 16c constitutes a bucket chain line 16b so that a L-shaped digging part is protruded toward the tilting boom 4 side.
