The HarborHoist Lift 6600 has a maximum boat length capacity up to 30 feet and can lift up to 6600lbs.
Vertical aluminum poles are attached front and back to lift, preventing lift from moving under the dock or rubbing on dock structure.
Mechanism securely attaches the lift to the dock. The plastic lined slide allows ease of movement with minimal noise. This option is used when piles are in line with receivers front and back (18ft of adjustment).
This bracket allows up to 6ft. of forward and backward adjustment of the slide mechanism. This will almost certainly allow capture of a set of piles.
