Abstract
A cable-driven telescopic boom with several boom segments repositionable between stowed positions and deployed positions. The boom includes multiple spaced apart and separate cables that engage pulleys connected to each boom segment. A drive system can be used to apply tension to the cables to reconfigure the boom from a stowed configuration to a deployed configuration.
Claims20
A telescopic boom positionable in a stowed configuration and in a deployed configuration, the telescopic boom comprising:
- a first boom segment having a first end and a second end opposite the first end;
- a second boom segment having its own first end and its own second end opposite its own first end, the second boom segment being positionable inside the first boom segment;
- and
- a drive mechanism connected to each of the first boom segment and the second boom segment, the drive mechanism including a cable and a motor that can apply tension to the cable, the cable is engaged with the first boom segment at a first location proximate to the first end of the first boom segment and at a second location proximate to the second end of the first boom segment, the cable is engaged with the second boom segment at a third location proximate to the first end of the second boom segment and at a fourth location proximate to the second end of the second boom segment, wherein the cable extends continuously between the first location, the second location, the third location, and the fourth location, and the drive mechanism can be actuated to apply tension to the cable to move the telescopic boom from its stowed configuration to its deployed configuration.

A telescopic boom positionable in a stowed configuration and in a deployed configuration, the telescopic boom comprising:
- a first boom segment having opposite ends;
- a second boom segment having opposite ends, the second boom segment being positionable inside the first boom segment;
- and
- a drive assembly comprising:
- a first cable;
- a second cable;
- a third cable, each of the first cable, the second cable, and the third cable being engaged with each of the first boom segment and the second boom segment, and each of the first cable, the second cable, and the third cable being equally spaced apart from the others of the first cable, the second cable, and the third cable around the first boom segment and the second boom segment;
- and
- an actuator that can apply tension to each of the first cable, the second cable, and the third cable to move the second boom segment from a stowed position to a deployed position relative to the first boom segment.
6 more elements
A telescopic boom positionable in a stowed configuration and in a deployed configuration, the telescopic boom comprising:
- a base portion;
- a first boom segment having a first end and a second end opposite the first end, the second end being coupled to the base portion;
- a second boom segment having a third end and a fourth end opposite the third end, at least a portion of the second boom segment being positionable inside the first boom segment;
- a third boom segment having a fifth end and a sixth end opposite the fifth end, at least a portion of the third boom segment being positionable inside the second boom segment;
- and
- a drive assembly including a spool, an actuator coupled to the spool, and a cable engaged with the spool, wherein the cable is engaged with the base portion, the first boom segment at a first location proximate to the first end of the first boom segment and at a second location proximate to the second end of the first boom segment, the second boom segment at a third location proximate to the first end of the second boom segment and at a fourth location proximate to the second end of the second boom segment, and the third boom segment at a fifth location proximate to the first end of the third boom segment and at a sixth location proximate to the second end of the third boom segment, the cable extending continuously between the spool, the base, the first location, the second location, the third location, the fourth location, the fifth location, and the sixth location, and the actuator can be actuated to move the spool to apply tension to the cable to move the second boom segment and the third boom segment so that the telescopic boom moves from its stowed configuration to its deployed configuration.
