Abstract: The present disclosure pertains to a trailer stroke extender for use in a hydraulic trailer system, adapted to be arranged between a first hydraulic trailer and a second hydraulic trailer. The system comprises a cradle frame and first and second hydraulic cylinders. The cradle frame has a first cradle-to-beam connector adapted to be connected to the first hydraulic trailer and has a second cradle-to-beam connector adapted to be connected to the second hydraulic trailer. The first and the second cradle-to-beam connectors are spaced apart from each other in a longitudinal direction of the trailer stroke extender. The first and second hydraulic cylinders are adapted to move a trailer load in a vertical direction relative to the cradle frame over a single stroke length. The hydraulic cylinders are arranged in the cradle frame at a distance from each other in a lateral direction of the trailer stroke extender.

Abstract: A trailer system includes a first trailer module, having a plurality of wheels, a loading bed, and a primary loading bed connector for connecting to a loading bed of a further trailer module to form a combined rigid loading bed. The primary loading bed connector is arranged below an upper surface of the loading bed of the first trailer module. A first jack system includes a first jack cradle, which has a jack holder, and a jack accommodated in the jack holder. A primary cradle connector is connected to the primary loading bed connector of the first trailer module and therewith connects the first jack cradle to the first trailer module. The jack holder extends at least partly below the upper surface of the loading bed of the of the first trailer module.
