Abstract
PURPOSE: To eliminate damage in the motor in such a way that controllability of valves is improved by using a two-capacity type (multicam type) hydraulic motor, further at the time of taking up heavy load, low speed drive is continued.
CONSTITUTION: A circuit is constituted by a two-capacity type hydraulic motor 1, a compound counter-balance valve 6 which makes two pieces of counter-balance valves into one piece, a valve 12 which makes one each of direction converting valve and two-speed valve into one piece, and a sequence valve 23. Change-over of normal and reverse, stop, low and high speed operations are performed in such a way that one operating part 36 operates a spool 22 of the valve 12. Even if the valve 12 is set to the high speed position by an operating part 36 at the time of taking up, it works to automatically continue low speed operation by the sequence valve 23.
