Abstract: The invention relates to a trailer (10), which includes a frame (12) comprising a front end (14) and a rear end ( 16 ), as well as a vehicle platform (18) for supporting a working machine (100) to be transported on the frame (12), wheels (22) for supporting the trailer (10) on a ground surface (104), at least one loading ramp (26) attached in an articulated manner to the rear end (16) of the frame (12) by means of a transverse pivot joint (28), wherein each loading ramp (26) is arranged to rest on the ground surface (104) in a loading position in order to move the working machine (100) onto the vehicle platform (18), wherein each loading ramp (26) includes a ramp frame (32), a first end (34) on the side of the frame (12) of the trailer (10) and a second end (36) opposite the first. The transverse pivot joint (28) is formed in the ramp frame (32) between the first end (34) and the second end (36) at a distance (d) from the first end (34) and includes at least one pivot pin (38) and at least one slot ( 40 ), which allows a limited inclination of each loading ramp (26) about a longitudinal axis between the first end (34) and the second end (36), wherein one of either said pivot pin (38) or said slot (40) is formed in the ramp frame (32) and the other is formed in the rear end (16) of the frame (12) of the trailer (10).

Abstract: The invention relates to a towing arrangement (10) for a towing earth-moving vehicle (12), the towing earth-moving vehicle (12) comprising a towing point (24) fitted under its chassis (14), which towing arrangement (10) includes a drawbar (26) arranged to be pivoted to the towing vehicle's (12) towing point (24) and a second end (29) comprising the drawbar's (26) towing point (30) for the device (100) to be towed, a first pivot (32) for pivoting the drawbar (26) under the rear axle (20) to the towing vehicle's (12) towing point (24) formed under the towing vehicle's (12) chassis (14), which first pivot (32) is in the transverse direction of the chassis (14), a second pivot (34) fitted to the drawbar's (26) second end (29), which second pivot (34) is vertical and arranged to transmit the load of the trailer (56) being towed rigidly to the first pivot (32), and a third pivot (44), located at one end (28, 29) of the drawbar (26), equipped with a shaft in the towing vehicle's (12) longitudinal direction, thus permitting the device (100) to tilt in the towing vehicle's (12) transverse direction, in which the towing arm (64) is rigidly attached to the drawbar's (26) rearmost pivot (34, 44). The invention also relates to a system, a trailer, and a method.
