AL425HD Axis II Heavy Duty

The single most important factor is the total weight of your mobility device — including the base unit, batteries, seat, and every accessory. Bariatric power wheelchairs can weigh 300-500+ lbs. Heavy-duty scooters add even more. Get an exact weight from your device manufacturer and add a safety margin. Never choose a lift rated at or below your device's weight.

Heavy-duty lifts place significant stress on your vehicle's frame, hitch, and suspension. Depending on your vehicle and the lift capacity, you may need upgraded suspension, a reinforced hitch receiver, or frame-mounted supports. Our technicians evaluate your vehicle's structural capacity and recommend any necessary reinforcements before installation.

High-capacity exterior lifts require a Class III (2") or higher hitch receiver rated for the combined weight of the lift and your device. Many vehicles come with lighter-duty hitches that are not sufficient. We verify your hitch rating and upgrade it if needed as part of the installation package.

Heavy-duty lifts draw more power than standard models. Your vehicle's electrical system must support the increased load without compromising battery performance. Some installations require a secondary battery, heavy-gauge wiring, or upgraded alternator output. We handle all electrical requirements during installation.

Heavy-duty lift installation is more involved than standard lifts due to the increased structural and electrical demands. Installation may require frame reinforcement, suspension upgrades, heavy-gauge wiring, and additional safety testing. Our factory-trained technicians have the expertise and equipment to handle high-capacity installations properly.
