In most instances it can take 4-6 people to move an assembled lift from the yard out into the water.  If you have seawalls rock walls  it can be more difficult to place and require more people.  Assistance from a standard appliance dolly, foam floats, a Smarte Jack Retractable Wheel Kit, or a CraftLander Lift Jack installation tool can make moving the lift into place and adjusting the pads to their proper height much easier and require fewer people.
