Description

The invention relates to a liftable carrying device with the features of the preamble of claim 1 and a rail vehicle in the form of a pocket wagon with at least one such carrying device.

In the prior art, in connection with the loading of a rail vehicle with cargo by means of a lifting device, cargo in the form of cargo that can be directly craned and cargo that cannot be craned directly is known.

Immediately cranable cargo refers to a cargo which itself has gripping edges for a lifting device, that is to say can be loaded by a lifting device essentially without further aids. An example of a load that can be craned directly is a craneable semi-trailer.

Loads that cannot be directly craned refer to a load that itself has no gripping edges for a lifting device. Such loads are often loaded by means of a lifting device, the lifting device having gripping edges for a lifting device. With such a lifting device, goods that cannot be directly craned can be made cranable. An ordinary semitrailer or, for example, a car can be cited as an example of a load that cannot be directly craned.

FR 2 965 257 A1 shows a lifting device with a first pair and a second pair of gripping edges, which are formed on two spaced apart and interconnected side members. When loaded on a rail vehicle designed as a pocket wagon, both pairs of gripping edges are located inside the pocket of the pocket wagon.

A liftable carrying device with the features of the preamble of claim 1 is based WO 2016/141399 A1 out. This document describes in particular (see page 4 , Row 28 to side 5 , Row 2 ) six pairs of gripping edges (referred to there as “receiving pockets”), all of which, viewed in the first direction, are arranged within the length of the at least two longitudinal beams, so that slightly different centers of gravity of the carrying device loaded with cargo can be taken into account.

The object of the invention is to provide a carrying device which can optionally be loaded with a first type of cargo (e.g. in the form of containers, semi-trailers, tractors, tractors, buses or light trucks) and a second type (e.g. in the form of short Trailers) can be loaded and safely lifted by a lifting device, the centers of gravity of the cargo of the first and second types differing so much from one another that safe lifting by the same carrying device according to the prior art would not be possible.

This object is achieved by a lifting device with the features of claim 1.

A liftable carrying device with the features of claim 1 enables an improved adaptation to widely differing centers of gravity, since the first pair of gripping edges, viewed in the first direction, is arranged or can be arranged outside the length of the at least two longitudinal beams, so that either cargo of a first type and cargo of one second type with the same carrying device can be safely lifted (in particular while maintaining a horizontal orientation of the cargo during the lifting process) by a lifting device.

Protection is also sought after for a rail vehicle in the form of a pocket wagon, with a pocket and with at least one carrying device according to the invention, which is arranged over the entire length of the drivable support inside the pocket and the first pair of gripping edges viewed in the first direction outside the pocket is arranged or can be arranged.

The distance between the gripping edges from one another in the first direction should be selected such that two gripping edges, which are spaced apart from one another in the first direction along a common longitudinal member, are carried out by a lifting device (together with the corresponding two gripping edges arranged on the other longitudinal member) for carrying out a lifting operation for loading - or unloading can be used.

Advantageous embodiments of the invention are defined in the dependent claims.

In one embodiment of the invention, it is provided that the gripping edges of the first pair of gripping edges are each formed on a carrier extension. Either a detachable connection between the beam extension and the longitudinal beam can be provided, or an undetachable, integral connection (preferably welded connection).

In the case of a design with a detachable connection, it is provided that each support extension can be detachably connected to one of the at least two longitudinal supports with a locking device (e.g. lockable bolt) (by opening and Closing the locking device) and each gripping edge of the pair of gripping edges is arranged on its carrier extension such that, when the carrier extension is connected to a longitudinal member, it projects in the first direction as viewed above the longitudinal member.

In one embodiment of the invention it is provided that the gripping edges of the second pair of gripping edges are each formed on a carrier attachment, each carrier extension being releasable with a locking device (e.g. lockable bolt) with one of the at least two longitudinal carriers (by opening and closing the Locking device) is connectable.

In one embodiment of the invention, it is provided that a third pair and a fourth pair of gripping edges are provided, which are formed on or in the at least two longitudinal beams. The third pair of gripping edges can be formed, for example, together with the first pair of gripping edges on the carrier extensions or independently of these. The fourth pair of gripping edges can be formed on separate support attachments.

If four pairs of gripping edges are provided, for example a set of two pairs of gripping edges can be used to engage a lifting device with a first center of gravity and a set of two other pairs of gripping edges can be used to attack a lifting device with a first center of gravity. Are z. B. only three pairs of gripping edges are provided, a pair of gripping edges must be an element of both sets.

It can be provided that the common component is displaceably or displaceably arranged on the side member between the at least two different positions.

In the case of a displaceable common component, guides can be provided on the side members. Alternatively, the side members themselves could be designed as guides. To reduce friction, friction-reducing coatings or attachments can be provided. Alternatively or additionally, rollers can be provided between the common component and the guides.

In the case of a displaceable common component, the longitudinal members can have fastening points at the at least two different positions.

In both cases, the locking device can be designed, for example, in the form of lockable bolts which, in the first case and / or in the second case, can be used in fastening points arranged on the longitudinal beams.

In one embodiment of the invention, contact patches are provided for the immediate installation of the carrying device on a terminal corridor.

In one embodiment of the invention, it is provided that the support which can be driven on extends over a length which is the same as the length of the longitudinal beams. However, it would be possible to use an accessible support with a shorter length.

The longitudinal beams do not have to have a constant height over their entire length, but can be provided with recesses which extend in the third direction.
