A large capacity boat lift includes a lift assembly mounted on each side of
a boat supporting platform. Each lift assembly includes a support
structure that carries a winder. A lifting cable is operably attached at
each of its ends to respective sections of the winder. A drive mechanism
operates the winder in first and second directions to selectively wind the
cable onto and off of the winder. The cable movably interengages a pair of
pulleys carried by the platform. A section of the cable between the
pulleys is engaged with the support structure such that winding the cable
onto the winder raises the platform and unwinding the cable from the
winder lowers the platform.
