Vehicle for transporting at least one silo container and Silo container for

The invention relates to a vehicle for transporting at least one silo container for loose goods in the construction industry with a swivel device hinged to the rear and vertically adjustable, to which the silo container can be secured at the back by means of at least one fitting or similar bearing element and can be swiveled relative to a loading area of the vehicle by rotating the swivel device about its vehicle-side hinge axis(es). The invention also covers a special silo container.

Vehicles of this type are used, for example, in the construction industry to transport silo containers for loose goods such as plaster, which can be removed or blown away on the construction site using augers or compressed air systems. These silo containers are transported lying down by trucks with appropriate superstructures and suitable silo container receiving devices and are set up at the construction site by swiveling them through 90°. The vehicles are only suitable for the silo containers described and cannot accommodate containers of other designs, for example containers suitable for rail transport.

Also known from DE-OS 42 44 109 of the applicant is a motor vehicle with a mast that can be pivoted about an articulated axis relative to the loading area, to which the silo container can be connected and on which it can be transferred from a vertical to a horizontal position.

For stackable so-called ISO containers with a cuboid outline for the transport of loose goods according to ISO standard in 20-foot lengths, there are transport vehicles with pivot pins protruding from the loading area according to DIN 70 014 (Part 1), which are in ISO-

the ISO container lying flat. This can be tilted to around 48° so that the loose material can be blown in or released in this position. Such ISO containers are transported by road and rail, i.e. in so-called combined transport.

Tipping the ISO containers allows a special design of semi-trailers by placing them at the rail terminal; here too, the ISO containers are tilted at an angle of around 48° for emptying. But even with such vehicles, construction site silos cannot be transported.

Knowing this state of the art, the inventor has set himself the goal of creating a vehicle of the type mentioned above, with which both of the container systems discussed can be transported and the construction site silos can be made suitable for rail transport.

The doctrine of the independent claim leads to the solution of this problem; the subclaims indicate favorable embodiments.

According to the invention, at least one swivel body guided in a pendulum path is attached to the free end of a support frame of the swivel device on guide rods that can rotate parallel to the direction of travel, from which a pivot pin protrudes, preferably of variable length, and whose free end can be inserted into an ISO fitting on a frame of the round silo container.

The invention also includes a support frame of the swivel device with thrust wedges or similar shaped bodies directed towards the rear of the vehicle and tapering towards the free end of the support frame, which are detachably inserted into counter elements protruding from the rear of the round silo container for connection to the round silo container.

B274DE1 3

According to a further feature of the invention, the swivel body is adjustable in length by a force accumulator
in particular by a piston/cylinder unit -- connected to the support frame; the piston forms a support triangle for the swivel body together with the handlebar and the support frame.

It is also possible that at least one hook protrudes from the support frame - next to or instead of the thrust wedge(s) - near its free end for connection to a counter element of the round silo container towards the rear.

The silo container for loose goods for construction purposes suitable for this vehicle with a receptacle of round cross-section arranged in a frame, with a funnel bottom at a distance from a base plate or similar end frame parts, is equipped with connecting fittings for attachment to counter fittings on the transport vehicle, whereby the connecting fittings are ISO corner fittings with front and side recesses for receiving pivot pins. The grid of these corner fittings corresponds to the standard grid of so-called ISO containers.

According to the invention, the rear side of this round silo container - the preferred length of 7150 mm - is assigned at least one pair of receiving pockets with a bottom opening for those thrust wedges. In addition, side gripper pockets can be provided.

Thanks to these specifications, a receiving system for the ISO containers and for round construction site silos is created. Modifications are made to these to make them suitable for rail transport.

According to the invention, vertically erectable ISO containers are created that can be used on transport vehicles for construction site silos; these vehicles contain receiving systems for both types of containers.

B274DE1

The advantage of the ISO containers is that they can be temporarily stored empty or full in a space-saving manner using a 90° vehicle, and this can be done using only the combination vehicle, i.e. without any aids.

The invention offers two variants as a construction site silo for rail transport. On the one hand, a round silo can be surrounded by a square tube frame with eight corner fittings in accordance with ISO standards with a length of twenty feet, with the advantage that this container is in the ISO system and can be stacked on top of one another with similar ones. The disadvantages are the small volume - only 17 m^ - and the cost of the comprehensive frame.

On the other hand, round silos with DIN 70014 dimensions can be used as swap containers. Based on the connection dimensions - the distance between the fittings is, as mentioned, identical to the ISO corner fitting dimensions - such a container for a combination vehicle according to the invention can also be transported by rail. However, the length of the swap container must be 1094 mm longer than the 6056 mm for the ISO 20-foot container.

For the receiving system, the invention shows a simple and easy-to-use conical hanging pocket on the silo with a correspondingly tapered receiving wedge on the station wagon; the conical design can compensate for an uneven position of the vehicle in relation to the silo.

On the other hand, the scope of the invention includes the described pivot pin locking with pendulum travel; with this holder, all ISO containers - regardless of the respective holder system - can be picked up in a standing position and placed on the vehicle.

Practical experience with construction site silo transport has shown that it is hardly possible to get a precise approach to the construction site silo. This inaccurate approach is compensated for by the individually adjustable pivot element.

The pivot element can be adjusted, for example, by means of a swivel element rotated by 90°. In any case, it is important that the pivot element that protrudes furthest can be moved closer to the ISO fitting by swiveling or telescoping.
