Abstract:
A boat lift includes four posts and four linear actuators, each attached to one of the posts. Each linear actuator includes an extendable and retractable member oriented for extension and retraction substantially parallel to the post. Ends of a first pair of the extendable and retractable members are connected to a first carrier and ends of a second pair of the extendable and retractable members are connected to a second carrier. A cradle or platform is supported by the first and second carriers. The boat lift may be supported by the ground, by a structure, for example, a dock, a sea wall or a wall of a boat house, or by pontoons.

Claim (Index 1):
A boat lift comprising a lifting mechanism and four support posts, each of the four posts having an upper end and a lower end, the lifting mechanism comprising:\n a first linear actuator connected to the first post, the first linear actuator having a first actuator cylinder and a first actuator rod substantially parallel to the first post, the first actuator rod extendable from the first actuator cylinder and retractable into the first actuator cylinder; a second linear actuator connected to the second post, the second linear actuator having a second actuator cylinder and a second actuator rod substantially parallel to the second post, the second actuator rod extendable from the second actuator cylinder and retractable into the second actuator cylinder; a third linear actuator connected to the third post, the third linear actuator having a third actuator cylinder and a third actuator rod substantially parallel to the third post, the third actuator rod extendable from the third actuator cylinder and retractable into the third actuator cylinder; a fourth linear actuator connected to fourth post, the fourth linear actuator having a fourth actuator cylinder and a fourth actuator rod substantially parallel to the fourth post, the fourth actuator rod extendable from the fourth actuator cylinder and retractable into the fourth actuator cylinder; a first carrier connected to the first actuator rod and to the second actuator rod; and a second carrier connected to the third actuator rod and to the fourth actuator rod; wherein the first and second linear actuators are configured to selectively move the first carrier between a first position relatively near the upper ends of the first and second posts and a second position relatively near the lower ends of the first and second posts; and wherein the third and fourth linear actuators are configured to selectively move the second carrier between a first position relatively near the upper ends of the third and fourth posts and a second position relatively near the lower ends of the third and fourth posts.
