DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention is concerned with equipment for loading a cargo space, such as an interchangeable platform or container, onto a vehicle and for its removal from same and/or for dumping the cargo space.
BACKGROUND OF THE INVENTION
In prior art, so-called hook-device type equipments are known for loading a truckbox or a container onto a vehicle. Such equipments are described, e.g., in the Finnish Patent Nos. 63,350 and 53,352.
When a truckbox or a container is being removed off a vehicle, at the initial stage of the movement a substantially horizontal path of movement of the grasping hook and, consequently, also of the truckbox or container rearwards is required before the truckbox or container is tilted. In the solution suggested in the Finnish Patent No. 63,350 this phase of horizontal shifting is produced by initially just pivoting an angle piece around its horizontal shaft. It is only after this that the horizontal middle frame of the loading equipment is pivoted, whereby the truckbox or container is tilted. In this prior-art equipment a distance of horizontal shifting can be accomplished up to about one meter.
OBJECTS AND SUMMARY OF THE DISCLOSURE
It is an object of the present invention to increase the said distance of horizontal shifting. The equipment in accordance with the invention is characterized in that the articulation point between the arm and the horizontal frame is placed further forwards than the articulation point between the folding frame and the horizontal frame. By means of this new mechanism, a horizontal shifting movement of about 2 meters can be achieved while the hook moves along a gentle S-curve. The construction in accordance with the invention improves the usability of the equipment in covered spaces of low height.
BRIEF DESCRIPTION OF THE DRAWING
The invention and its details will be described in further detail in the following with reference to the accompanying drawings, wherein;
FIGS. 1 to 4 are schematical side views of a lorry provided with a prior-art loading equipment at different stages of loading,
FIG. 5 shows the loading equipment as viewed from above,
FIG. 6 is a side view of the angle piece of the loading equipment,
FIGS. 7 and 8 show a truck in two different dumping positions,
FIG. 9 is a side view of the equipment in accordance with the present invention in its resting position,
FIG. 10 shows the same at the final stage of the horizontal movement, and
FIG. 11 is an "exploded view" of the components of a part of the equipment shown in FIGS. 9 and 10.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
The loading equipment shown in FIGS. 1 to 6 comprises three frame parts: a rear frame, a middle frame 4, and an L-shaped folding frame or hook part 5. As is shown in FIGS. 1 to 4, the rear frame 3 is, at its rear part, attached to the rear end of the chassis beams 1 of the truck through articulation points 6. The rear frame 3 can pivot around the articulation points 6 relative the chassis beams 1, i.e. the rear frame 3 can be pivoted relative the chassis beams 1 to the ordinary dumping position (FIGS. 7 and 8). At the rear end of the rear frame 3, there are support rolls 19 for supporting and guiding the interchangeable platform 2 during loading. The rear frame 3 also includes locking equipment 18 for locking the interchangeable platform onto the loading equipment. To the rear frame 3, a middle frame 4 is attached by one of its ends pivotably by means of a transverse horizontal shaft 7 or by equivalent articulation points. Facing the ends of the rear frame 3, laterally projecting stop pieces 17 are fitted on the middle frame 4, and prevent pivoting of the middle frame 4 to below the rear frame.
In a direction extending outwardly of FIGS. 3 to 5, two parallel main cylinder-piston devices 13 are fitted between the middle frame and the chassis beams 1 of the lorry.
To the front end of the middle frame 4 or in immediate proximity of the front end of the middle frame 4, a hook part 5 is attached by the rear ends of the horizontal portions
