DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Smaller-sized industrial trucks including a forklift function mostly are constructed as motor-driven trucks to be accompanied and are guided and operated by means of a shaft. The shaft is connected to the driving means and directly actuates the driving wheel, above which a battery-operated electric motor is provided. It is known to arrange the shaft and the driving motor on one side asymmetrically. In the housing of the driving means, furthermore, the battery and a hydraulic aggregate are provided for actuating the lift cylinder. The lift cylinder is a component part of a lifting means onto which a carriage is guided at variable height. The lifting means usually is composed of two spaced mast channel members which are arranged in front of the driving means and are supported by the wheel arms connected to said driving means. The lift carriage comprises guiding rollers on opposite sides which guiding rollers are guided within the mast channel members being U-shaped in cross-section. The lift carriage forms a whole with the carrying tines of the cargo fork which, up to but excluding the wheel arms, are capable of descending, with the cargo fork being covered.
It is the object of the invention to provide a forklift truck which, at the same time, can be used as advertising medium.
SUMMARY OF THE INVENTION
The invention is based upon the knowledge that the mast is suitable for providing it with planiform or relief-like coverings which do neither impair the function of the forklift truck nor its operation. The advertising media, for instance, may be a covering or a plate which covers at least part of the lifting means.
In a preferred embodiment of the invention provision is made for said advertising media to be arranged on a single lift mast centrally provided between the wheel arms, preferably as a facing of the so-called monomast on the rear side above the housing of the driving means.
According to a development of the invention, the lift mast or monomast, preferably, is integrated into the housing of the chassis and only slightly projects from the outer contour. The projecting end only needs to be selected at a size which prevents the cargo carriage from getting into touch with the chassis. By this, the monomast can be most effectively and solidly connected to the chassis so as to absorb the moment caused by the cargo carriage and, especially, by the cargo.
In spite of the solid arrangement of the monomast in the chassis the interior space of the housing is not unnecessarily confined. On the contrary, there still is available a continuous space for the accommodation of a battery and the various aggregates.
According to a further development of the invention, the covering, preferably, is box-shaped. The covering prevents the operator from reaching inside the mast and injuring himself. Besides, a corresponding optical design gives the forklift truck an attractive look. Preferably, the covering is made of synthetic material and, therefore, may be shaped in any way whatever. It may show different objects by means of a corresponding embossing or design which allows the lifting means to be used as advertising surface or advertising medium at the same time.
Preferably, the covering is adapted to be attached detachably, and, for instance, may be clipped into the lift mast. Thus, there may be used a covering selected according to the user and serving his advertising purposes. Besides, the covering may comprise one or several openings for the accommodation of objects or different functional inserts. So, for instance, it is thinkable to use the covering for the accommodation of a control- and/or display module. If there are concerned any shaft-guided forklift trucks the actuation of the truck is made with the aid of any actuating element provided within the shaft head. Sometimes, however, it is also desirable to integrate any additional displays and operating elements which, according to the invention, may be arranged within the covering. Alternatively, a functional insert may be provided
