SELF-PROPELLED WORKING MACHINE

摘要

A tool repositioning mechanism ( 20 ) is provided between a fore end of a telescopic boom ( 12 ) and a cargo handling tool ( 35 ). The tool repositioning mechanism ( 20 ) is constituted by a head member ( 21 ), swing arm ( 25 ), swing cylinder ( 29 ), tool mount member ( 30 ) and a link ( 34 ). As a swing cylinder ( 29 ) is expanded or contracted, the cargo handling tool ( 35 ) is shifted to the right or to the left of the telescopic boom ( 12 ) through the tool repositioning mechanism ( 20 ). Accordingly, even if a spot of a lifted cargo on the cargo handling tool ( 35 ) is deviated from a cargo unloading spot in a lateral direction, the position of the lifted cargo can be adjusted easily by the tool repositioning mechanism ( 20 ) to unload the cargo accurately on a specified spot.
