"The truck bed lift is a heavy-duty hoist that lifts all scooters and power chairs weighing up to 400 lbs. An offset arm loads and unloads mobility devices from the passenger-side curb or over tailgates up to 24"" tall. The passenger-side lift features adjustable boom heights and extenders to accommodate different size mobility devices. A wired remote allows the user to control the lift without having to leave the cab. An included docking device prevents spinning by stabilizing your mobility scooter or power chair during loading. A transferable three-year warranty is included with the pickup truck hoist from Harmar."
