摘要： A boat lift system for raising and lowering a multi-hulled boat from and into a body of water, the boat including first and second laterally spaced apart hull structures, includes a carrier assembly and a drive system. The carrier assembly is configured to hold the boat. The carrier assembly includes a crossbeam having a length and first and second cradle assemblies spaced apart along the length of the crossbeam and secured to the crossbeam. Each of the first and second cradle assemblies is configured to receive a respective one of the first and second hull structures and includes a coupling bracket and a pair of longitudinally extending runners each secured to the coupling bracket and positioned to receive and support the respective one of the first and second hull structures. The coupling bracket connects and resists lateral separation between the runners. The drive system is operable to selectively raise and lower the carrier assembly.

摘要： A drive system for use with a cable and a carrier for raising and lowering a payload includes a reel, a drive mechanism, a cable slack control mechanism, and a tension adjustment system. The drive member is operatively connected to the reel to rotate the reel in a winding direction when the drive member is rotated in a raising direction, and to controllably rotate the reel and/or permit the reel to rotate in an unwinding direction when the drive member is rotated in a lowering direction. The cable slack control mechanism is operative to automatically selectively decouple the drive member from the reel while the drive motor is rotating the drive member in the lowering direction when a tension on the cable does not exceed a threshold tension and/or the cable is fully unwound from the reel. The tension adjustment system is operable to selectively adjust the threshold tension.

摘要： A drive system for use with a cable and a carrier for raising and lowering a payload between a lower position and an upper position, the carrier being configured to hold the payload, the cable being connected to the carrier, includes a reel, a drive mechanism, a cable slack control mechanism, and a tension adjustment system. The reel is configured to receive the cable. The reel is rotatable in each of a winding direction to wind the cable onto the reel to raise the carrier and an unwinding direction to unwind the cable from the reel to lower the carrier. The drive mechanism includes a drive member and a motor operable to forcibly rotate the drive member in each of a raising direction and a lowering direction. The drive member is operatively connected to the reel to rotate the reel in the winding direction when the drive member is rotated in the raising direction, and to controllably rotate the reel and/or permit the reel to rotate in the unwinding direction when the drive member is rotated in the lowering direction. The cable slack control mechanism is operative to automatically selectively decouple the drive member from the reel while the drive motor is rotating the drive member in the lowering direction when a tension on the cable does not exceed a threshold tension and/or the cable is fully unwound from the reel. The tension adjustment system is operable to selectively adjust the threshold tension.

The reel is rotatable in each of a winding direction to wind the cable onto the reel to raise the cradle and an unwinding direction to unwind the cable from the reel to lower the cradle. The drive mechanism includes a drive member and a motor operable to forcibly rotate the drive member in each of a raising direction and a lowering direction.
