摘要：
The invention 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, comprising:
- a cradle frame, with a first cradle-to-beam connector adapted to be connected to the first hydraulic trailer and a second cradle-to-beam connector adapted to be connected to the second hydraulic trailer, the first and the second cradle-to-beam connectors being spaced apart from each other in a longitudinal direction of the trailer stroke extender,
- a first hydraulic cylinder and a second hydraulic cylinder which are adapted to move a trailer load in a vertical direction relative to the cradle frame over a single stroke length, and being arranged in the cradle frame at a distance from each other in a lateral direction of the trailer stroke extender.
- a cradle frame, with a first cradle-to-beam connector adapted to be connected to the first hydraulic trailer and a second cradle-to-beam connector adapted to be connected to the second hydraulic trailer, the first and the second cradle-to-beam connectors being spaced apart from each other in a longitudinal direction of the trailer stroke extender,
- a first hydraulic cylinder and a second hydraulic cylinder which are adapted to move a trailer load in a vertical direction relative to the cradle frame over a single stroke length, and being arranged in the cradle frame at a distance from each other in a lateral direction of the trailer stroke extender.
