Keeping a boat on a lift will prevent the need for bottom-painting the boat. Bottom painting reduces the value of your boat. You will save on storage fees, wrapping and winterizing fees, while having year-around availability to launch your boat. You will also be able to better protect your boat from storm damage, theft, and vandalism. Most people are surprised to find that installing a lift costs much less than they originally figured. In most cases, lifts pay for themselves within 5-years!
Lifts are measured by capacity in pounds, rather than the length of the boat. Once you’ve calculated the fully-loaded wet weight of your boat, you can figure on a lift capacity that will safely handle your boat. You should consider what size boat you may be upgrading to over the next few years before purchasing your lift. If you’re not sure about the weight of your boat, please look at our lift selector on the contact page, or contact us directly at 1-800-545-5603. We can accommodate most any boat, from a PWC to the largest yacht!
In the saltwater environment, marine grade aluminum (6061-T6) offers a greatly increased life expectancy when compared to galvanized steel. When aluminum lifts were first introduced, the primary drawback to aluminum was cost. The large structural shapes needed were hard to obtain. As structural aluminum became more common, the cost of aluminum lifts are now similar to the price of galvanized lifts. Also, the lightweight properties of aluminum allow the contractors to sometimes install our boat lifts without a barge or crane, significantly lowering installation costs. Today there is really no reason to purchase a galvanized lift.
If a lift is selected with wooden bunks we will send weights to insure that the cradles will not float. IMM Quality Boat lifts’ revolutionary Perma-Bunk aluminum bunks with white vinyl covers, prevent any cradle-floatation. The aluminum bunks and covers are guaranteed for 10-years. There are inferior aluminum bunks available, but they don’t incorporate a custum extrusion “internal I beam” structure that integrates the white vinyl covers perfectly without need of top rivets that might scratch your hull.
Elevator lifts do not require outboard pilings, allowing elevators to be used where outboard pilings are not permitted, in cases with hard bottom or deep water conditions that make the installation of piles impractical, or in cases where there just isn’t enough room to access a traditional four post lift. A disadvantage of elevator lifts is that the tracks stay in the water and therefore, need to be protected from electrolysis and ground voltage.
Imm Quality Boat Lifts is recognized as the industry leader in the manufacture of elevator boat lifts. The key to a good elevator lift design is the strength of the joint between the trolley and cradle arm. Please see the web page depicting our elevator lifts for details and pictures. Note how the joint is reinforced, making it the strongest in the industry and how the design also allows you to bring your boat up closer to the dock than any other elevator lift.
At first glance, a beamless boat lift may seem the better choice because there is no “top beam” to navigate across when entering the boat or to be seen from the house. While this is true, there is a trade-off for that benefit. When winch-heads are attached to the sides of the pilings, they exert a side-load on the pilings. Therefore, the dock structure and installed pilings (especially external free-standing pilings) need to be installed properly and of sufficient construction to withstand this sideways force. If not, pilings may tend to lean over, or even shift due to the side loading. Our conventional top beam lifts can be set in a “low-profile” configuration, which allows you to use a covered top beam as a boarding platform, while avoiding the side load issues associated with beamless lifts.
There are basically three types of drive bearings: 1. Ball or Roller Bearings may seem great, but they are not durable because of corrosion and because they are not engineered for low RPM, high load conditions. 2. Metal to Metal: Some manufacturers use bronze, while some use aluminum or even plastic bearings. In both cases, they require frequent lubrication and maintenance. We feel that a boat lift should free up your time, not use it up with additional chores. 3. Maintenance-free, engineered polymer bearings are a very high tech, self-lubricating material. Imm Quality boat lifts have used these bearings for many years, and our Igus tribopolymer bearings have never worn out. They are dirt resistant, corrosion-free, quiet, reduce maintenance costs and increase the service life of our lifts. We use Igus maintenance-free bearings on all of our lift lines.
