摘要： A watercraft lift assembly is provided. The watercraft lift assembly may include a frame, a pair of opposing cantilever arm assemblies and a lifting system. The frame may include a plurality of vertical posts and overhead elements forming a generally simple cubic lattice frame defining a watercraft operational envelope. Each cantilever arm assembly may include a pair of cooperating cantilever arms. Each cantilever arm may be generally L-shaped having a horizontal arm portion and a vertical arm portion slidably secured to an adjacent vertical post. Each horizontal arm portion may include a housing for slidably receiving an extension element. On each cantilever arm assembly, a cantilever bunk may be pivotably connected to the ends of the cooperating extension elements so as to operably engage the bottom surface of various watercrafts when the pair of cantilever arm assemblies moves from a low position to a raised position under the power of the lifting system.

摘要： A gear transmission system embodying a unique twin pitch belt is provided. The twin pitch belt provides external first pitch gear teeth and a second pitch gear teeth synchronously engaging a fixed housing gear teeth and output gear teeth, respectively. The first and second pitch gear teeth may have the same gear pitch if different number of teeth though offset by a distance relative to each other. The first and second pitch gear teeth have less teeth than the housing and output gear teeth, in turn twice countering the rotation of an input shaft operatively associated with the twin pitch belt, resulting in the output gear teeth rotating in the same direction as the input shaft.
