The boatlifts we install typically require 4 pilings for installation.  They are manufactured in Florida from IMM / Quality Boat Lifts.  Visit their website at:  These lifts are a chain driven lift constructed of aluminum.  They have 2 - 3/4 HP stainless steel motors, grooved cable winders, full carpet bunk boards and aluminum cable beam covers.  Remote control and automatic limit switches are also available.  They range in sizes from 4500# to 32,000# and larger if necessary.  We have designed an aluminum canopy system which will attach to the top beam of our lifts we install.
