APPARATUS FOR LIFTING IMPLEMENT

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for lifting an implement capable of selecting a form lowering the implement by own weight and a forcible lowering form by pressure of a lift cylinder and reducing a cost. SOLUTION: This apparatus for lifting can operate one lift cylinder as a double-acting hydraulic cylinder 13 and operate the other lift cylinders as single- acting hydraulic cylinders 12 among a plurality of lift cylinders for operating lift arms 9. All of these lift cylinders are used as single-acting hydraulic cylinders when the implement is normally lowered and one lift cylinder which can be operated as the lift cylinder 13 is changed to the double-acting type hydraulic cylinder 13 when the implement is forcibly lowered.
