Abstract
A transfer arrangement for transferring a semi-trailer onto an intermodal pocket wagon from a ground location beside the wagon, or vice versa, may include base roller beams of a first lifting mechanism supported by the ground at the ground location and intended for lifting the semi-trailer up from the ground. Corresponding wagon roller beams of a second lifting mechanism may be supported by the rail or the ground under the wagon. The wagon roller beams may be elevated to substantially the same height as the base roller beams or lowered towards the ground. A transfer mechanism may be provided for transferring the semi-trailer sideways from the first lifting mechanism to the second lifting mechanism in the elevated condition thereof.

A transfer arrangement for transferring a semi-trailer onto a rail-borne, intermodal pocket wagon from a ground location beside the wagon, or vice versa, the semi-trailer being placed in parallel with the rail, the transfer arrangement comprising:
- base roller beams of first lifting means, supported by the ground at the ground location and configured to lift the semi-trailer by the base roller beams vertically up from the ground;
- corresponding wagon roller beams of second lifting means configured to be supported by the rail or the ground under the wagon, the wagon roller beams being configured to be elevated through openings between side beams of the wagon to the same height as the base roller beams or being configured to be lowered towards the ground;
- a drive mechanism configured to transfer the semi-trailer sideways from the base roller beams to the wagon roller beams in the elevated condition;
- a base structure, which is configured to be placed at a ground location beside the wagon;
- wherein the base structure includes the first and the second lifting means;
- and
- wherein each first lifting means includes stanchions on the base structure configured to guide the base roller beam, which is perpendicular to the rail and which can be moved between a lowered inactive position and an elevated active position.
A transfer arrangement for transferring a semi-trailer onto a rail-bone, intermodal pocket wagon from a ground location beside the wagon, or vice versa, the semi-trailer being placed in parallel with the rail, the transfer arrangement comprising:
- base roller beams of first lifting means, supported by the ground at the ground location and configured to lift the semi-trailer vertically up from the ground by elevating the base roller beams;
- corresponding wagon roller beams of second lifting means configured to be supported by the rail or the ground under the wagon, the wagon roller beams being configured to be elevated through openings between side beams of the wagon to the same height as the base roller beams or being configured to be lowered towards the ground;
- a drive mechanism configured to transfer the semi-trailer sideways from the base roller beams to the wagon roller beams in the elevated condition;
- and
- a base structure, which is configured to be placed at a ground location beside the wagon;
- wherein the base structure includes the first and the second lifting means
- wherein each second lifting means is foldably attached to or can be pushed out from the base structure and includes a lift beam configured to be supported by the rail;
- wherein the wagon roller beam is configured to be elevated or lowered by hydraulic cylinders between the lift beam and the wagon roller beam;
- and
- wherein the wagon roller beam and the base roller beam are in line with each other when elevated.
