Claims

[Scope of utility model registration request]

In a forklift equipped with a tail mechanism for tilting a mast, a pallet holding member for pressing a pallet supported by the fork is provided on a lift bracket having a fork so as to be movable up and down via a clamp cylinder. A backward tilt side circuit of the tail cylinder of the tail mechanism is connected to a clamp side circuit of a hydraulic circuit including a cylinder and a control valve of the cylinder via a sequence valve, and the tail cylinder is connected to an open side circuit of the hydraulic circuit. At the same time as connecting the anteversion side circuit through the sequence valve,
A simple pallet holding device in which each circuit of the tail cylinder is provided with a check valve in parallel with the sequence valve.
