When the fork positioner lever is pushed forward, the spool is moved to fork close position by the
pilot oil pressure from the remote control valve(11). The oil from hydraulic main pump(1) flows into
main control valve(3) and then goes to the small chamber of fork positioner cylinder(15) by pushing
the load check valve of the spool. The oil from large chamber of the cylinder(15) returns to
hydraulic oil tank(34) at the same time. When this happens, the forks are close each other.
