Description

The present invention relates to a caddy, in particular for the transport of engines, transmissions or other heavy aggregates and / or assemblies for motor vehicles.

Reusable transport containers, packages or crates are known in a variety of different configurations. From the DE 20 2010 007 457 U1 , from which the present invention proceeds, a transport packaging is known comprising a bottom plate comprising a bottom plate and a bottom floor in the form of a undercarriage having pallet and four side panels, the side panels are connected to each other via bracket corner joints and the bottom plates at least one to be transported unit have adapted recess. The floor panels have above each in the middle of the page and corner arranged cutouts, in which the side panels can be inserted. It is envisaged that the entire transport packaging is made of wood and can be produced inexpensively with little effort and also has sufficient stability to be used for the transport of heavy equipment.

Such reusable transport packaging has proven itself in practice. However, it has been found that, especially with longer transport routes, for example, overseas, the stability of the transport packaging is often insufficient to allow reuse. Another disadvantage of the known transport packaging is that the recesses provided in the base plates for receiving the units to be transported are made individually for the units to be transported, so that a corresponding transport packaging can be used exclusively for the corresponding units. When changing the cargo, and the transport containers must be changed, which means a considerable additional cost in view of the relatively high cost of producing such a transport container.

The invention was therefore based on the object to provide a transport packaging available, which has advantages over the prior art.

This object is achieved by a caddy with the features of claim 1. Advantageous embodiments and further developments of the transport frame according to the invention are the subject of the corresponding dependent claims.

The present invention is a further development of the DE 20 2010 007 457 U1 described transport packaging to be transported with the engines, transmissions or other heavy equipment and / or assemblies for motor vehicles. Thus, starting from the base plate already described in the aforementioned utility model application, a stable and universally applicable transport frame has been developed, which is particularly suitable for the transport of engines, transmissions or other heavy aggregates and / or assemblies for motor vehicles.

The transport frame comprises at least one interchangeable base plate, which is designed as a milled wooden plate and laterally arranged cutouts for receiving Eckverbindern and at least one adapted to be transported unit milled recess for receiving the unit to be transported. The caddy has a understructure, which is formed as a rectangular base frame made of square steel tubes with two longitudinal struts and two cross struts, wherein the longitudinal struts and cross struts are connected to each other via four vertically arranged corner posts made of steel pipes. In addition, the transport frame comprises a provided as a support for the at least one bottom plate upper steel frame, which is arranged on the inner sides of the corner posts and also consists of steel tubes. The steel tubes are welded together, while the at least one interchangeable base plate is connected via clip-like corner connectors with the upper steel frame.

Compared with the known transport packaging made of wood, the transport frame according to the invention has the advantage that it is much more stable, so that even with longer transport routes under high load reuse of the transport frame is easily guaranteed. In addition, the base plate is replaceable by simply loosening the corner connectors, so that the transport frame can be used universally for different floor panels for the transport of different aggregates.

As with the already known transport packaging, the unit to be transported is fixed on the bottom plate by means of spring bolts, for which on the bottom plate at the edge of the at least one provided for receiving the unit to be transported recess at least one, but preferably two or three, spring bolts are arranged ,

Also, in the region of the at least one recess additional to be transported Aggregate adapted attachments and attachments provided as fixing aids.

Advantageously, the corner posts at their lower ends downwards conically widening, frustoconical feet on the one hand favor a solid state of the caddy on the ground and on the other hand serve as stacking aids for stacking several transport containers on top of each other, wherein the truncated cone-like feet of the caddy to be stacked be placed on the upper ends of the corner posts of the base transport frame.

In order to facilitate the reuse of the transport frame, or the required return transport of the transport frame, the corner posts are constructed in two parts, wherein the lower part of the corner posts is formed of a U-shaped steel tube, in which the upper part of the corner post engages as a square steel tube. The connection between the lower and the upper part of the corner post via a engaging in a slot in the upper part of the Eckpfostens pin, which is arranged in the lower part of the Eckpfostens. In this way, the upper part of the Eckpfostens be folded with a vertical movement along the slot up to the inside of the caddy, with the corner posts in the folded state rest on the bottom plate. In this way, the caddy can be folded to save space for the return transport.

The fixation of the upper part of the corner post in the unfolded state is supported by a protruding stop on the outside of the upper part of the Eckpfostens, wherein the protruding part of the stopper rests against the lower part of the Eckpfostens and thus stabilizes the upper part of the Eckpfostens.

An advantageous embodiment of the transport frame according to the invention provides that in each case two adjacent corner posts are connected on one side in their upper parts on a steel reinforcement strip, so that a kind of side panel is formed, which can be folded down as a unit.

To facilitate the folding handles for actuating the folding mechanism are arranged at the upper parts of the corner posts, with the aid of which the upper part of the corner post can be pulled vertically upwards and then folded down.

On the base frame of the Caddy underrun aids for receiving forks of a forklift are provided.

With the inventive concept, which is based on a stackable and collapsible steel frame in combination with interchangeable floor panels, further advantages can be realized. Thus, it is provided in a further advantageous embodiment that instead of a large base plate with a plurality of recesses for receiving aggregates smaller single floor panels are used, then single floor panels for different units can be combined, so that in a transport rack different units can be sent together , For this purpose, it is only necessary that the transport frame comprises a plurality of interchangeable single floor panels, wherein the single floor panels rest on one of the size of the single floor panels adapted steel frame. In order to prevent slippage of the individual floor panels, lateral stops are provided in an advantageous embodiment. A further advantageous embodiment provides that in the middle of the caddy a T-shaped steel strip is arranged as a traverse, in which the individual bottom plates can be inserted and thus stabilized.

The versatility of the transport frame according to the invention can additionally be increased by providing, in an advantageous embodiment of the present invention, adapters for the corner posts, by means of which the height of the corner posts can be varied, so that larger and higher units can be transported with the base transport frame, without the need for special transport packaging or racks.

The present invention will be described in detail below with reference to preferred embodiments illustrated in the accompanying drawings. Showing:
