When the lift control lever is pulled back, the spool is moves to lift 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 large
chamber of lift cylinder(13) by pushing the load check valve of the spool.
The oil from the small chamber of lift cylinder(13) returns to hydraulic oil tank(34) at the same time.
When this happens, the forks go up.
