Claims

[Scope of utility model registration request]

a twist stopper and a lift stopper provided on each of the spool moving mechanism of the twist lock operating directional control valve and the spool moving mechanism of the lift operating directional control valve;
A forklift truck comprising: a detection mechanism that detects the state of a twist lock pin attached to a spreader; and a stopper fixing/releasing mechanism that operates based on a pin state detection signal from the detection mechanism.
