Abstract

The invention relates to a heavy-load transport vehicle (10) for transporting an elongated object, having a tractor (14), a multi-axle trailer (16) and a carrier (18) for the elongated object supported on the trailer and on the tractor (14), wherein the trailer (16) and the carrier (18) are rotatable in relation to each other about a vertical axis (52) of the transport vehicle (10). According to the invention the carrier is supported on the tractor (14) via a goose-neck (22), the trailer (16) has at least one rigid axle (42, 44) and at least one steering axle (40), and in a steering operation mode during the journey, the steering axle (40) of the trailer (16) is steerable in relation to the trailer (16) about the vertical axis (52) as a function of the rotational movements of the carrier (18).

Claims

1. A heavy-load transport vehicle (10) for transporting an elongated object, having a tractor (14), a multi-axle trailer (18) and a carrier (18) for the elongated object supported on the trailer and on the tractor (14), wherein the trailer (16) and the carrier (18) are rotatable in relation to each other about a vertical axis (52) of the transport vehicle (10), the trailer (16) having at least one rigid axle (42, 44) and at least one steering axle (40), and in a first steering operation mode during transport the steering axle (40) of the trailer (16) is steerable in relation to the trailer (18) about the vertical axis (52) as a function of the rotational movements of the carrier (18) by means of a hydraulic circuit comprising at least two acts off the steering axle (40) and at least one other hydraulic cylinder (64) picks up rotational movements of the carrier (18) in relation to the trailer (16), and wherein hydraulic fluid is exchanged between the hydraulic cylinders by the hydraulic circuit, characterized by a second steering operation mode, according to which, during the transport, the steering axle (40) of the trailer (16) is steerable actively and Independently from the movements of the tractor (14) and the trailer (18), and characterized by a device amount of hydraulic fluid in a hydraulic circuit.

2. The heavy-load transport vehicle according to claim 1, characterized by a rotating assembly connected torque proofed with the carrier (18) and being rotatable in relation to the trailer (16) about the vertical axis (52).

6. The heavy-load transport vehicle according to claim 1, characterized in that the carrier (18) is displaceable in direction of its longitudinal axis (56) in relation to the trailer (16).

7. The heavy-load transport vehicle according to claim 8, characterized by braking or locking devices (82) arranged between the carrier (18) and the trailer (16), and that, after release of the braking or locking devices (82), the carrier (18) is displaceable in direction of its longitudinal axis (56) in relation to the trailer (16) by means of the tractor (14).

8. The heavy-load transport vehicle according to claim 6, characterized in that the carrier (18) comprises at least two adjacent telescopic elements (84, 86, 88, 90), that each respective front element is at least partially insertable into the hollow inside of the respective rear element, and that the outside of the rearmost element (90) is provided with a linear guidance (80) for the trailer (16).

9. The heavy-load transport vehicle according to one of the previous claims claim 1, characterized in that the goose-neck (22) comprises a device (92) for lifting and lowering the front end of the carrier (18).

10. The heavy-load transport vehicle according to claim 9, characterized in that the distance between the tractor (14) and the trailer (16) is shortened by the lifting of the carrier (18).

11. The heavy-load transport vehicle according to claim 9, characterized in that the device for lifting and lowering of the front end of the carrier (18) comprises at least one parallelogram kinematics (98) and a parallel steering (110, 112).

12. The heavy-load transport vehicle according to claim 9 characterized in that the device for lifting and lowering of the front end of the carrier (18) is arranged between a generally horizontally oriented neck part (94) of the goose-neck (22) and a support part (96) of the goose-neck (22) which is borne on the tractor (14) and is rotatable in relation to the tractor (14).

13. The heavy-load transport vehicle according to claim 1, characterized in that the carrier (18) is pivotable in relation to the trailer (16) about a pivot axis (76) which is vertical to a longitudinal axis (56) of the carrier (18) and parallel to the ground.
