Cable winders are a common upgrade that slide over the pipe and have grooves that allow the cable to wrap neatly upon them. This prevents the cable from rubbing against itself and protects the galvanized surface of the pipe. It will help prolong cable life and will actually increase the speed of the boathouse lift. The trade off is that the cable winders reduce the lifting capacity of the hoist because they increase the speed of wrapping cable.
Some boathouses are built with steel. If the joists are boxed steel beams then the typical installation brackets may be used. However if the joists are steel I-beams they cannot be drilled through for attaching the standard brackets. Special I-beam brackets must be used which will clamp to the I-beam so that no drilling is necessary. Drilling through the side of an I-beam destroys its structural integrity.
Most boathouses are constructed of wood although some may be made with steel. They are designed with roofs to protect boats from the weather and may or may not have sides that extend down to the deck below.
Guide posts can be used with cradles to ensure that the boat is centered between the cables. The guide posts that we provide clamp on to the cradle I-beams and are adjustable. You will need to provide PVC pipe to slide over these brackets that are high enough to be seen and used from the boat.
Boathouse lifts use either polyester slings for lifting the boat or steel cradles. Slings can be more economical but do require that the boat’s hull has proper reinforcement so that the slings don’t “squeeze” the hull. here
Setting up the spacing between the slings or cradle beams is important for proper support of the boat and proper functioning of the boathouse lift. It is important that the center of gravity of the boat is in the middle between the two slings or cradle beams. The boat’s center of gravity can be obtained from the boat manufacturer. Then calculate the positions of the slings or cradle beams. First, set the rear sling or cradle beam near the rear of the hull but make sure it clears the motor and is properly supporting the boat. Then calculate the distance from that rear support to the center of gravity of your boat. Since the center of gravity is also the center of your slings or cradle, use that measurement to find the position for the front sling or cradle beam. Make sure the front sling or cradle beam is squarely under the flat part of the hull. If it is too far forward and the hull is starting to slope up then re-adjust the position of your supports. Finally, double check everything to make sure the center of gravity of the boat is centered on the lift and that the support of the boat’s hull is sufficient. more
A cradle generally provides better support than slings for a boat. A cradle is made up of two steel I-beams that have attachment points on the ends for cables. They also include brackets for holding the bunk boards, which are the carpeted wooden boards that the boat actually rests upon. Boat cradles can be set up for different hull shapes. They can be adjusted for v-hull boats or flat bottom boats. Pontoon brackets are also available which allow a pair of bunk boards on each side of the cradle for both pontoons. more
Most boathouses are constructed of wood although some may be made with steel. They are designed with roofs to protect boats from the weather and may or may not have sides that extend down to the deck below.
Wireless remotes are available for our boathouse lifts. It is very convenient to be able to lower the lift when bringing the boat in since the water level may have changed. Some people prefer to send the lift back up as they take their boat out on the water. The remote’s control box replaces the manual switch and controls the motor. The control box also has manual controls as well. A wireless transmitter is included and additional transmitters are available for purchase. Remotes can be purchased with an automatic stop that has a preset “up position” and a preset “down position” for one-touch operation.
Guide posts can be used with cradles to ensure that the boat is centered between the cables. The guide posts that we provide clamp on to the cradle I-beams and are adjustable. You will need to provide PVC pipe to slide over these brackets that are high enough to be seen and used from the boat.
