The invention relates to an apparatus according to the species definition of claim 1.

Containers of standard weight and size are known and are now used in international transport, whether by land, sea or air. It is necessary to equip stations, ports and airports with a special lifting device for handling these containers, the containers being rectangular in the shape of a parallelepiped and provided with lifting openings located in the area of the four corners of their lower or upper surfaces. Containers only need to be lifted from these openings. The floor of the container is formed by a steel plate supported by two longitudinal and transverse beams, in which case it is important that it is possible to handle the container without having to further strengthen this floor.

Cranes, loading crane scaffolds or high-performance transport scaffolds specially designed for this purpose are known to be used for this purpose. Such lifting devices are expensive and 2 65193 inconvenient because the weight of the container can rise to 30 tons and it can be more than 12 m long.

The container, thus loaded onto a truck from a cargo ship or railcar, is then transferred by road to a user, who in turn must have an unloading platform, a crane, or a high-capacity crane rack to unload the container.

The object of the present invention is to avoid these disadvantages by arranging the road vehicle in such a way that it can load the container placed on the ground with its own power on its platform, transport it to the user and also unload it on its own power.

According to the invention, the task is solved according to the characterizing part of claim 1.

The accompanying drawings in the form of examples make the invention and its various features more comprehensible. Figures 1, 2, 3, 4, 5, 6 and i '7 show the successive steps of loading a self-propelled land vehicle according to the present invention, starting from the time the con- the tainer is placed on the ground.

Fig. 15 is a similar view with the front of the container in the initial stages of lifting (as in Fig. 4).

Fig. 16 shows the arrangement of the wheels of the support beam when they meet the end of the pivoting base (as in Fig. 4).

Fig. 17 shows a support beam on a pivoting platform as it rolls by means of its rollers (as in Fig. 5).

The apparatus according to the invention comprises a land vehicle constructed in a known manner from the cabin A, the platform B, the swivel platform C and the lifting mechanism D. The vehicle has front wheels E and rear wheels F. This system is known.

The apparatus according to the invention is mainly further characterized in that it comprises a support beam G arranged to move on the tracks of the pivoting platform C, the pivoting platform comprising two side bogies H at its rear and a supporting support K provided with wheels 1. The movement of the support beam G is controlled by a winch M. located at the front of the pivot base C. The connection between the winch M and the support beam G is arranged with a rope 2.

This arrangement provides a vehicle for handling and transporting containers P commonly used in international transport. These containers can reach a total weight of about thirty 4,619,33 tons and a length of the order of 12 meters.

They include a base 3 provided with processing openings on the sides at four corners, indicated by reference numeral 4 (Figures 1, 8, 10 and 12) at the front and reference number 5 (Figure 1) at the rear.

When the container B is located on the ground (Fig. 1), its problem is to load it on the turntable C using only the means arranged in the land vehicle, i.e. no mobile crane scaffolds or lifting cranes are used. In addition, the treatment should only take place using openings 4 and 5. However, the treatment should not damage the strain 3, which has been used without additional reinforcing members.

Finally, the laden truck (Figure 7) should comply with the provisions of the law relating to road traffic, especially with regard to overall width. Since the standard size of the container P is only 6 cm smaller than the limit prescribed by law, it is clear that it is necessary to handle and fasten it using front fastening members 8 (Figures 9 and 13) and side plates 9 with a thickness 10 not exceeding 3 cm .

The support beam G (Fig. 8-17) comprises a parallelepiped-shaped cross beam 11 made of a metal plate to fit the front plate 12 of the container P. At each end of the cross beam 1 there is a vertical shaft pin 13 for the press 8. This is formed from a piece of metal provided with a flat arm 14 which fits into a plate 15 on the side of the corresponding container P. This arm 14 is provided at its lower part with a pin 16 which extends laterally suitably into the adjacent recess 4.

Each member 8 has a horizontal shaft pin 17 at its tip for a paw or shoe 18 with a flat T-shaped cut. This shoe 18 fits simultaneously on the plate 12 and 15 of the container P while at the right angle, as shown in Figures 9, 10 and 5 65193 11. The shoe 18 thus forms a simple adjustable mounting surface for the press 8 when the latter is mounted on the front of the container.

The cross beam 11 also has a mounting pin 19 at each end extending horizontally so as to engage the opening 20 of the press 8 when the latter is turned back, as shown in Figures 12 and 13. The protruding part of the pin 19 further has a transverse bore 21 (Figure 13). into which the retaining pin 22 (Fig. 10) is inserted to lock the clamp 8 to the front of the container. In order that the end of the pin 19 does not extend beyond the size limit determined by the press 8 when the latter is opened (Figs. 12 and 10), the opening 20 is placed in the bottom of the recess 23, the recess 23 being formed on the outer side surface of the member 8. The depth of the recess 23 is sufficient to include a portion of the retaining pin 22 and the protruding pin 19.

The support beam G also includes two rounded paws, i.e. shoes 24, welded to the lower surface of the cross beam 11 so that they rest directly against the ground with the container base 3, at the front of which the machinery is pressed (Figures 2 and 14). Each shoe 24 is provided with a circumferential collar 25 for accommodating a rope 2 (Figures 11, 16 and 17). In this way, the rope 2 does not move out of place when the shoes 24 rest on the ground.

To facilitate the handling of the container, the light winch M is provided with a relatively flexible rope 2, i.e. a rope with a relatively small diameter. Due to the weight of the movable container, it is necessary to double the rope 2. For this purpose, two counter-wheels 26 are welded to the rear end of the crossbar 11 of the support beam G and the rope part 2a rotates horizontally between them. On each side of the wheels 26, the rope 2 forms two vertical parts 2b resting on the collars 25 of the shoes 24. The rope 2 thus extends twice in front of the shoes 24 of the support beam G and is attached to the drum of the winch M at each end (not shown).

Outside the shoes 24, a fork 27 is welded to the lower surface of the cross member 11 of the support beam G to support the horizontal shaft pin 28 6 65193 (Figs. 10 and 11). Two movable supports 29 are articulated to the ends of the shaft pin 28 and are connected by a shaft pin 30 around which the roller 31 rotates freely. The movable supports 29 are provided with a counterweight 32 positioned so that the roller shaft pin 30 is in front of the vertical plane defined by the shaft pin 28 when the support beam G depends on the rope 2, as shown in Fig. 15.

The fork 27 further includes two stops 33 and 34 located on each side of the shaft pin 28, respectively on the front and rear sides of the latter. The stop 33 is located above the shaft pin 28, while the stop 34 is below. Thus, as a result, when the articulated supports 29 are made to pivot so that the shaft pin 30 rests against the bottom of the stopper 33, the roller 31 is in the retracted state (Fig. 14), i.e. it does not extend below the lower level determined by the shoes 24. In this case, the support beam G rests on the ground with its shoes 24, while the rollers 31 remain retracted. When the support beam is raised, the counterweights 32 cause the rollers 31 to lower, as shown in Fig. 15. If the supports 29 are then caused to pivot backwards (Figs. 16 and 17), the shaft pin 30 on each roller 31 rests against the rear stop 34 of the fork 27 and the roller 31 extends 24 below the lower level prescribed. The rollers 31 can then support the load because their shaft pins 30 are thus located behind a vertical plane determined by the shafts 28 of the shaft pins (Fig. 17).

The rollers 31 roll on longitudinal rails 35 (Figs. 11, 16 and 17) arranged on the upper surface of the pivoting base C. Each rail 35 is provided on the side with guide flanges 36 extending upwards.

At its rear end, the pivotable base C is provided with a transverse shaft pin 37 on which a roller 38 is mounted for free rotation. The latter is provided with two collars 39 required by the invention to correspond to the collars 25 of the shoes 24 and intended to prevent the rope 2 from breaking when the support beam G rises behind the pivoting base C, as illustrated in Figures 4, 5 and 16.

The chassis pivoting from its rear axle extending over the articulated shaft 40 of the truck chassis B (Figures 1, 3 and 7) is integral with the support K, dimensioned so that its roller 1 is against the ground when the lifting gear D is operated, which receives the load. the car to push backwards under the container during loading (Figures 4-6), while avoiding excessive sagging of the rear end of the vehicle.

The operation of the loader is as follows:

To load the container P while it is directly on the ground (Fig. 1), the truck A-B-C-D is reversed and its pivoting platform C is lifted by a hoist D. The winch M is then made to operate and release the rope and lower the platform end to the ground. The support bar G is normally suspended at the rear of the vehicle, with the vehicle running empty.

With the support beam G thus positioned close to the front of the container, it is pressed into it (Fig. 2) by closing the two presses 8, as shown in Figs. 12 and 13, while the rope 2 remains loose. During this phase of operation, the support beam G rests on the ground with its shoes 24 (Fig. 14) and its rollers 31 remain automatically retracted. The winch M is then started to rotate the rope 2, which raises the support beam G under the front of the container (Figures 3 and 15). As soon as the shoes 24 come off the ground, the counterweights 32 automatically turn the rollers 31 downwards.

The twisting of the rope 2 on the winch M is continued while the truck A-B-C-D is in neutral, which allows it to travel automatically backwards under the container (Figures 4 and 16). The shoes 24 come into the plane of the fastening rollers 38 and the rollers 31 are held in place by the lower ends of the rails 35. The axle pins 30 of the rollers 31 then automatically engage the rear stops 34, as shown in Figures 5 and 17. The front of the container then rests on the rails 35 via the rollers 31 of the support beam G as the support beam simultaneously approaches the winch M in proportion to the rearward movement of the truck.

8 65193 At the end of this operating step, the rear end of the container detaches from the ground, while its base 3 is supported on the boggel H, as shown in Fig. 6.

When the support beam G reaches the level determined by the winch M, the latter is stopped and the pivoting platform C is allowed to fall back onto the platform B by shrinking the crane D (Fig. 7). This operation can be automated by connecting a tank connected to the hydraulic circuit.

Upon reaching its destination, the truck can be unloaded by lowering the container P to the ground by its own power, thus operating in the reverse order similar to the procedures described above.
