Industrial truck e.g. counterbalance fork-lift truck, has intermediate wing force-subjected by spring unit to opening direction and staying in contact with stopper that is fastened at main wing, where both wings are locked in obtuse angle

摘要

The truck has a vehicle frame with a frame portion including a frame opening. A door is pivoted outwardly about a vertical rotation axis (A1), and is connected with the frame using a double hinge. Another rotation axis (A2) is set parallel to the axis (A1), and is moved when the door pivots about the axis (A1). An intermediate wing (3a) is force-subjected by a spring unit to an opening direction when the door is in closed position. The intermediate wing stays in contact with a stopper, which is fastened at a main wing (3b), where the intermediate and main wings are locked in an obtuse angle.
