Boat lifts are designed to last for about the same time as your boat, or even longer if you're lucky. Boat lifts can last as long as 25 years if they are maintained and used properly. You can have many factors that affect your boat lift's life span. Some of these are beyond your control like extreme weather or water conditions. However, preventative maintenance is one of the best ways to make sure your boat lift lasts years.
Your boat lift should be treated as an investment, just like a boat. Routine boat lift maintenance protects the equipment against premature wear and damage. This also helps to prevent corrosion and rust and allows you to identify parts that need to be replaced or repaired.
While you may not be in a position to eliminate every possible risk that your lift could face, routine maintenance can help you avoid any potential problems. Boat lifts require maintenance for the following reasons:
Rust: A boat lift's biggest threat is rust. Any wet or humid environment can cause the metal to rust. All metal parts on your boat lift are vulnerable to rust. This can significantly reduce the life expectancy of your lift if it is not properly managed.
Broken cables: Cables that drive a lift are susceptible to wear. They need to be inspected and maintained. Cables can become frayed, rusty, kink, or broken if they are left in water or lack tension.
Water damage: water can cause rust and damage to beams, CRADLES, and gearboxes. Water can damage the lift's mechanical parts if it gets under or into the motor, gearboxes, or other covers.
Sheave alignment: When your cables are pulled up and wound around the drum or spool they can become misaligned. They can wear unevenly, or create slack, which could lead to additional maintenance.
Your boat lift will run smoothly for many years by being well-maintained and performing routine inspections.
