Abstract
Trailer, container, transport system and method for handling a container. The trailer (1) has a frame structure (11) pivotally connected to a drawbar (21) and at least two substantially parallel elongated guides (12) for guiding linear movement of a flat-bottomed container (3) along the frame structure (11) through corresponding front rollers (30) and/or guide rails (31) arranged on the bottom of the container (3) when being pulled by a winch (17) arranged on a towing end (40) of the trailer (1) or when being pushed in a direction away from the winch (17) by a resilient pushing device (14) arranged on the frame structure (11).
Claims16
A single or dual axle trailer for transporting a container, the trailer comprising:
- a towing end and an oppositely arranged loading end;
- a drawbar arranged at the towing end and configured to be attached to a towing vehicle;
- and
- a frame structure pivotally connected to the drawbar for selectively allowing the frame structure to pivot about a pivot axis parallel with the single or dual axle;
- the frame structure comprising:
- at least two substantially parallel elongated guides for guiding linear movement of the container along the frame structure;
- a winch for pulling the container from the loading end in a direction towards the winch;
- and
- a pushing device configured to push the container in a direction away from the winch,
- wherein the pushing device comprises a bracket arranged slidably on the frame structure and at least one resilient element configured to urge the bracket away from the winch.
A container comprising a substantially flat rectangular bottom and side walls extending from each edge of the bottom together defining an at least partially enclosed space above the bottom for accommodating cargo;
- the container further comprising at least two parallel guide rails arranged under the flat bottom, the guide rails being arranged substantially parallel to a second and fourth edge of the rectangular bottom and extending from a first edge of the bottom towards a third edge of the bottom, wherein the guide rails comprise a planar bottom surface that curves or angles upwards at the first edge thereby defining a contact surface for slidably guiding the container onto a transport vehicle such as a trailer,
- wherein the container further comprises container front rollers arranged at the first edge adjacent to the guide rails in a lifted position off the ground when the container is resting on the ground,
- wherein each front roller is arranged on an outer side of an adjacent guide rail towards the closest of the second or fourth edge.
