Abstract

The present invention relates to a truck crane with a winch, in particular a hoisting winch, which is mounted on the uppercarriage, wherein the truck crane includes means for raising and/or lowering the winch.

Claims

1. A truck crane with a winch (1), which is mounted on an uppercarriage, wherein

the truck crane includes means (10, 11) for raising and/or lowering the winch (1),

the winch (1) is releasably connectable with the truck crane to be removed and then be mounted again by the means (10, 11) for raising and/or lowering the winch (1), and

the winch (1) is liftable into a rotary platform frame (4) of the uppercarriage from below by the means (10, 11) for raising and/or lowering the winch (1).

2. The truck crane according to claim 1, wherein the winch (1) is also insertable into the rotary platform frame (4) of the uppercarriage from above by an auxiliary crane.

3. The truck crane according to claim 1, wherein the winch (1) is movable by the means (10, 11) for raising and/or lowering the winch (1) on the uppercarriage from a first position into an operating position located at a higher level with respect to the height direction of the truck crane and/or from an operating position into a first position located at a lower level with respect to the height direction of the truck crane.

4. The truck crane according to claim 3, wherein the first position is a transport position of the winch (1) on the crane.

5. The truck crane according to claim 3, wherein the first position is a further operating position, which permits an operation of the truck crane without ballast.

6. The truck crane according to claim 3, wherein the winch (1) is lockable in the first position via a latch (50) which fixes a bolt (6) in an oblong hole (9) such that the truck crane is also operable with the winch (1) disposed in the first position.

7. The truck crane according to claim 6, wherein locking the winch (1) in the first position is effected automatically.

8. The truck crane according to claim 6, wherein the locking of the winch (1) is released automatically when it is raised into the operating position.

9. The truck crane according to claim 1, comprising a device for accommodating a ballast, which at the same time forms the means (10, 11) for raising and/or lowering the winch (1).

10. The truck crane according to claim 1, wherein the means (10, 11) for raising and/or lowering the winch (1) comprise a pallet (10), which is movable in a vertical direction by hoisting means (11), wherein the winch (1) and/or a ballast can be moved into an operating position by the pallet (10).

11. The truck crane according to claim 10, wherein the pallet is boltable to the uppercarriage in the operating position.

12. The truck crane according to claim 10, wherein the pallet (10) includes adjustable seats (8) on which the winch (1) is erectable and positioned in a defined way.

13. The truck crane according to claim 1, wherein the winch (1) is boltable to the uppercarriage.

14. A truck crane with a winch (1), which is mounted on a uppercarriage, wherein

the truck crane includes means (10, 11) for raising and/or lowering the winch (1),

the means (10, 11) for raising and/or lowering the winch (1) comprise a pallet (10), which is movable in a vertical direction by hoisting means (11),

the winch (1) and/or a ballast is movable into an operating position by the pallet (10), and

the winch (1) rests on the pallet (10) bolted to the uppercarriage in the operating position.

15. A truck crane with a winch (1), which is mounted on a uppercarriage, wherein

the truck crane includes means (10, 11) for raising and/or lowering the winch (1),

the winch (1) is boltable to the uppercarriage, and

bolting the winch (1) to the uppercarriage is effected by an oblong hole (9), which allows a movement of the winch (1) from an operating position into a first transport position, which is located at a lower level with respect to the height direction of the truck crane.

16. The truck crane according to claim 15, wherein the winch (1) is lockable in the first position via a latch (50) which fixes a bolt (6) in the oblong hole (9) such that the truck crane is also operable with the winch (1) disposed in the first position.

17. A truck crane with a winch (1), which is mounted on a uppercarriage, wherein

the truck crane includes means (10, 11) for raising and/or lowering the winch (1) and

comprising two or more winches, which are raisable and/or lowerable by the means (10, 11) for raising and/or lowering the winch.
