System for moving a work machine

A system for moving a work machine equipped with a crawler chassis or a wheeled chassis, the system comprising a towing vehicle, a trailer arranged to be towed with the towing vehicle, and a towing arrangement for the towing vehicle, wherein:

• the towing vehicle comprises:
• a vehicle chassis;
• a front axle with front wheels and a rear axle with rear wheels arranged in the vehicle chassis at a distance from each other;
• and
• a towing vehicle's towing point arranged under the vehicle chassis between the front axle and the rear axle;
• the trailer comprises:
• a trailer chassis comprising sides, a towing end and a loading end, and a towing arm at the towing end;
• an essentially level deck comprising a front end and a rear end, fitted on top of the trailer chassis;
• and
• wheels fitted on both sides of the trailer chassis at sides of the deck;
• and
• the towing arrangement comprises:
• a drawbar comprising:
• a first end pivoted to the towing vehicle's towing point and a second end having a drawbar's towing point for a pivoted connection with the towing arm of the trailer for towing the trailer, wherein the drawbar is arranged essentially parallel to the vehicle chassis and extends in a forward direction of the towing vehicle from the second end of the drawbar behind the vehicle's rear axle to a front side of the towing vehicle's rear axle;
• a first pivot having an axis in a transverse direction of the vehicle chassis for pivoting the drawbar under the rear axle to the towing vehicle's towing point formed under the vehicle chassis;
• a second pivot having a vertical axis fitted to the drawbar's second end and being arranged to rigidly transmit a load of the trailer being towed to the first pivot;
• a third pivot, located at one of the first and second ends of the drawbar and equipped with a shaft in a longitudinal direction of the towing vehicle to permit the trailer to tilt in a transverse direction of the towing vehicle, wherein the towing arm of the trailer is rigidly attachable to the drawbar's second pivot;
• a vertical support attached to the drawbar and arranged to support the second pivot;
• an upper drawbar comprising two ends and attached at one of the two ends to the vertical support and at the other one of the two ends to the vehicle chassis;
• and
• a connector arm connecting the upper drawbar to the towing vehicle's towing point by running over the rear axle, wherein the drawbar, the upper drawbar, and the connector arm form a closed structure surrounding the rear axle.
