The description relates to a loading trailer which comprises a wheel bogie (4), a chassis (2) supported by the wheel bogie, and a gooseneck (3) for connection to a drive vehicle. The chassis is lowerable and raisable in relation to the wheel bogie for the purpose of being driven under a flat bed (5) and for lifting the flat bed with its load. In order to facilitate the aligning of the loading trailer (1) when driving it under the flat bed, at least the rear part of the chassis (2) is equipped with aligning guides (6) which work against the inner sides of the flat bed (5). The aligning guides (6) are preferably made up of arms which extend obliquely forwards and are adjustable by hydraulic cylinders and which have at their ends guide rolls which in the final position can be locked in depressions (9) in the flat bed. The front part of the chassis (2) also has preferably guides (7), which may be fixed.

Loading trailer

The invention relates to a stacking apparatus for stacking pipes or other similar long pieces into a stack of a predetermined shape for bundling and storage. The purpose is to provide an apparatus in which the stacking need not be interrupted for the duration of the binding up of the bundle and in which, on the other hand, the pipes are not subject to battering. The apparatus includes an assembling table (5) for the pipes (1), a lifting device (7) equipped with electromagnetic gripping means (8) for transferring the pipes, in groups corresponding to a stack layer, from the assembling table, and a stacking table (11) for receiving the layers between adjustable side supports (12). In accordance with the invention there is provided a bundling table (14), which is also equipped with adjustable side supports (12) in such a way that it can be brought to the same shape as the stacking table (11), in which case the bundling table is, furthermore, movable in order to take a bundle from the stacking table (11) for binding and conveying away. The bundling table is preferably arranged below the stacking table (11), in which case the stacking table is divided into two parts, and its parts are transferrable to the sides in such a way that the bundle can be lowered between these parts. The support surface of the assembling table is made up of resilient rails (6) by means of which a magnetic contact with each pipe (1) is ensured. The gripping means is also provided with centering means (9).
