With a cantilever lift, the weight of the boat is transferred from the cradle through two H-shape structures to the base of the lift frame. The two H-shape structures lie almost flat in a horizontal position when the lift is down in the water, and are pulled by a cable into a vertical position in order to lift the boat up out of the water. This simple design allows for the use of a single cable at the front of the lift and just three pulleys.
The main drawback to a cantilever lift is that the lift travel is limited by the height of the H-shape levers. Most cantilever lifts have 40″ of lift travel. If you have a boat that requires 18″ of water to float (as most stern drives do), a 40” lever is enough to raise it 22″ above the water (40”- 18”= 22”), which is plenty for most but not all applications. If you need more lift – because you get very large waves on your lake or want to tuck your boat up tight under a high canopy and the lake level has a tendency to fluctuate – you should consider a vertical lift. Also cantilever lifts tend to lose there mechanical advantage when the boat exceeds 4000lbs
Some lift retailers suggest you should also consider a vertical lift if your shoreline is particularly shallow, but this is not true. Most cantilever lifts, like vertical lifts, will lower the lift cradle until it is nearly level with the base of the lift frame. Cantilever lifts may even have a slight advantage in very shallow water for two reasons. First, unlike a vertical lift, they do not need to be perfectly level, so there is a reduced need to raise the back end of the lift on the legs. Second, the carriage on a cantilever lift moves backward into deeper water as it drops.
Quality and durability you can see
|Heavy-Duty All-Aluminum Construction
Hewitt takes no shortcuts. Some lift makers use nothing more than a bolt for critical pivot joints. Hewitt lifts are designed with double-reinforced pivots that are made with structural aluminum tubing and welded, through-hole construction – superior strength for superior reliability.
It is not unusual for poorly built lifts to sway or even break when subjected to frequent use. Hewitt lifts are built for the real world. Crossbars are reinforced on the top and bottom with extra large gussets that are welded on both sides for greater lateral stability and overall strength.
While lesser brands may simply bolt pulleys to the frame, Hewitt lifts have specially designed enclosures. Pulley assemblies are mounted in reinforced plate aluminum boxes that are welded directly to the frame. Cantilever lifts also use fewer pulleys and all parts are easily accessible for reduced maintenance.
