Claim:
1. A transport device, that is arranged to be moveable in a first direction forward, and which transport device comprises: a chassis, and a loading device to pull an interchangeable platform to the transport device in another direction that forms a sharp angle with the first direction, and which transport device is arranged to target a gravity support force to the interchangeable platform, wherein the transport device comprises an unloading device that is arranged to target in addition to the gravity support force to the interchangeable platform a force, of which direction forms an obtuse angle or straight angle with the first direction; in which case the transport device is arranged to unload the interchangeable platform from the transport device backwards along the transport device with the aid of the unloading device, the transport device further comprising an arm that is directed or can be directed into such direction that it belongs to a vertical plane encompassing a longitudinal direction of the transport device, a vertical hinge, by which the arm is arranged to pivot with reference to the chassis, so that a first end of the arm is arranged to be movable in relation to the chassis in a horizontal direction when the transport device is on a horizontal surface; in which case the interchangeable platform can be moved to the transport device and/or from the transport device in a direction that is not parallel with the first direction or opposite to the first direction, a tilt hinge, by which the arm is connected to the chassis, so that the first end of the arm is arranged to be movable in a vertical direction in relation to the chassis when the transport device is on the horizontal surface, a carrier movably attached to the arm, an arm latch configured to lock the carrier to the arm, an apparatus configured to couple the interchangeable platform to the carrier, fastening equipment to fasten the interchangeable platform to one or more of the loading device, an unloading device or a combined loading and unloading device, at least one winch to move the fastening equipment in a direction of the arm forward and backward, a loading reel, a loading cable, an unloading reel, and an unloading cable wherein reeling the loading cable on to the loading reel is configured to pull the interchangeable platform on to the transport device and reeling the unloading cable to the unloading reel is configured to pull the interchangeable platform from the transport device, at least one roll to guide the interchangeable platform and/or the cable; in which case the transport device is arranged to pull the interchangeable platform to the transport device and unload the interchangeable platform from the transport device backwards by a turning arm and winch, wherein the at least one roll is disposed behind the tilt hinge and attached to the arm, the interchangeable platform is configured to be lowered to the ground supported by the loading cable, and the arm is configured to turn, while loading of the interchangeable platform, so that a distance between the interchangeable platform from a vertical plane including a longitudinal direction of the arm gets smaller.
