System for lifting and moving heavy objects
A transport system is for transporting an object back and forth between a storage area and a target area. The transport system has a pedestal for being placed at one of the storage area and the target area. The transport system has a main boom pivotably connected to the pedestal. The main boom has a far end configured for being supported by the other one of the storage area and the target area while allowing for at least one rotational degree of freedom between the main boom and the other one of the storage area and the target area. The main boom has a span that is passively adjustable in length. Furthermore, the transport system has a transport boom coupled with the main boom, and an object handler guided by the transport boom and configured for handling the object to be transported between the storage area and the target area.
1. A transport system for transporting an object back and forth between a storage area and a target area, the transport system comprising:
a pedestal for being placed at one of the storage area and the target area,
a main boom pivotably connected to the pedestal, wherein the main boom has a far end that is configured for being supported by the other one of the storage area and the target area while allowing for at least one rotational degree of freedom between the main boom and the other one of the storage area and the target area, wherein a span of the main boom is passively adjustable in length, wherein the main boom is either telescopic or foldable, at least during a first operational mode of the transport system,
a transport boom being coupled with the main boom, the transport boom extending in a horizontal direction from the storage area to the target area, in operational use, wherein the transport boom is movably mounted to the main boom,
a coupling between the transport boom and the main boom configured for actuating the transport boom for adapting a position of the transport boom relative to the main boom, and
an object handler movable along or moved by the transport boom and being configured for handling the object to be transported between the storage area and the target area.
2. The transport system according to claim 1 , wherein the far end of the main boom comprises a vertical support for resting on the other one of the storage area and the target area.
3. The transport system according to claim 1 , wherein the main boom comprises a first sub-boom and a second sub-boom pivotably connected to the first sub-boom for allowing adjustment of the span of the main boom.
4. The transport system according to claim 1 , wherein the main boom comprises at least one telescopic joint for allowing adjustment of the span of the main boom.
5. The transport system according to claim 1 , further comprising an object handler actuator for manipulating a position of the object handler relative to the transport boom.
6. The transport system according to claim 1 , wherein a length of the object handler is adjustable for facilitating picking up or releasing of the object.
7. The transport system according to claim 1 , wherein the object handler is configured for gripping or releasing a gripping interface of the object.
8. The transport system according to claim 1 , wherein the object handler is controllably rotatable for manipulating an orientation of the object when suspended from the object handler.
9. The transport system according to claim 1 , further comprising a transport apparatus at the storage area for receiving the object and moving it within reach of the object handler or outside the reach of the object handler.
10. The transport system according to claim 1 , further comprising a further transport apparatus at the target area for receiving the object and moving it within reach of the object handler or outside of reaching of the object handler.
11. The transport system according to claim 1 , wherein the one of the storage area and the target area is placed on a floating vessel or floating platform.
12. The transport system according to claim 9 , wherein the transport apparatus is adjustable in height to accommodate for tidal changes and/or loading condition of one of the storage area or the target area.
13. The transport system according claim 10 , wherein the further transport apparatus is adjustable in height to accommodate for tidal changes and/or loading condition of one of the storage area or the target area.
14. The transport system according to claim 1 , wherein the other one of the storage area and the target area comprises a support configured for receiving an end of the main boom or a vertical support of the main boom.
15. The transport system according to claim 10 , wherein the transport apparatus is adjustable in height to accommodate for tidal changes and/or loading condition of one of the storage area or the target area.
16. The transport system according to claim 1 , further comprising a second coupling between the transport boom and the main boom.
17. The transport system according to claim 4 , wherein the main boom comprises at least two telescopic joints for allowing the adjustment of the span of the main boom.
18. The transport system according to claim 17 , wherein the movement of each of the two telescopic joints is controlled by an actuator.
19. The transport system according to claim 18 , wherein the actuator of each of the two telescopic joints has a locking mode, wherein said actuator is stiff for locking the position of its respective telescopic joint, and a free-float mode, wherein said actuator can freely extend or contract for allowing for the passive adjustment of the length of the span of the main boom.
20. A transport system for transporting an object back and forth between a storage area and a target area, the transport system comprising:
a pedestal for being placed at one of the storage area and the target area,
a main boom pivotably connected to the pedestal, wherein the main boom has a far end that is configured for being supported by the other one of the storage area and the target area while allowing for at least one rotational degree of freedom between the main boom and the other one of the storage area and the target area, wherein a span of the main boom is passively adjustable in length, wherein the main boom is telescopic, at least during a first operational mode of the transport system, and wherein the main boom comprises at least two telescopic joints for allowing adjustment of the span of the main boom,
a transport boom being coupled with the main boom, the transport boom extending in a horizontal direction from the storage area to the target area, in operational use, and
an object handler movable along or moved by the transport boom and being configured for handling the object to be transported between the storage area and the target area.
