This type of lift also requires a solid seawall, and is primarily used when installation of pilings is not permitted. Elevator lifts are more expensive than comparable vertical lifts, and a portion of the tracks is constantly submerged. Consequently, they require more maintenance than vertical lifts. The first lifts were made of galvanized steel, and some are still manufactured using that material. They're the least expensive, but have short warranty periods.
Ace lifts are available only in galvanized steel.
Only by examining the various lifts is it possible to judge their relative durability. Look carefully at the thickness of the metal and at the way the beds are suspended. Check the size of the drive shafts, the beams and the cables. This is true of other lift components, as well. To my mind, the more that is bolted on, the more adjustable the lift and the easier it is to repair.
