Claims

[Scope of utility model registration request]

In a forklift with a single-stage three-stage full-free mast structure, in which a hydraulic hose suspended from a hose pulley on the upper part of the middle mast is connected to a full-free cylinder of the inner mast via a hose connector arranged on the back of the inner mast, the hose connector of the inner mast is installed. Set the position so that the connector is above the lower beam of the middle mast when the inner mast is moved to the roller replacement position where the lower end of the lift roller protrudes from the lower end of the middle mast, while the hydraulic hose on the connector connection side is set. A hydraulic hose arrangement structure for a forklift, characterized in that the hose is folded and held in a U-shape below the connector by a hose holder attached to an inner mast.
