Harmar AL425HD
The AL425HD is the heavy duty version of Harmar's two axis inside hoist lift. It raises a manual wheelchair, a power wheelchair or a scooter weighing up to 450 lbs. and swings it into the vehicle, both under power from a hand control. It weighs 70 lbs. installed, its arm reaches higher and its length adjusts less far than the standard AL425, and Harmar puts a universal base adapter in the box.
A heavy duty hoist that loads your chair or scooter inside the vehicle
The AL425HD raises a manual wheelchair, a power wheelchair or a scooter weighing up to 450 lbs. into your vehicle under power. It lifts and it rotates from a hand control, the offset post lets you unload at the side of the vehicle, and Harmar builds it to keep a backup camera working.
Built for real life
What stands out
Power lifting and power rotation
The boom raises and swings under power from a weather-resistant hand control, so neither the lift nor the turn is done by hand. A wireless key fob is available and it is listed in the step headed Accessories.
Takes up to 450 lbs. inside the vehicle
It lifts a manual wheelchair, a power wheelchair or a scooter and places it inside, so your equipment travels in the vehicle rather than on a platform behind it. That is 50 lbs. more than the standard AL425 carries.
The offset post unloads at the side
Harmar sets the post off to one side, so the mobility device can be unloaded at the side of the vehicle rather than directly behind it.
A universal base adapter comes in the box
The lift bolts to the vehicle floor on a base adapter and Harmar includes the universal one. If your vehicle takes one of the named adapters instead, you can choose it in the step headed Base adapter and it is charged at list price.
A docking device holds your equipment, and it is sold separately
Harmar does not include one, because the right part depends on your chair or scooter. Choose the one that matches your equipment in the step headed Your docking device, or tell us what you have and we match it for you before your order ships.
The AL425HD is the lift to look at when your power wheelchair is too heavy for the standard AL425 and you still want it travelling inside the vehicle. The 450 lbs. capacity is the whole reason this model exists, and it covers the large mid-wheel chairs that sit above the 400 lbs. line. Both movements are powered, the raise and the swing, and the offset post means the equipment comes off at the side of the vehicle instead of directly behind it. Harmar puts a universal base adapter in the box, so most vehicles need nothing extra to mount it.
There are three honest caveats, and two of them are specific to this model rather than the range. Harmar does not offer the battery pack here, so this lift is wired into the vehicle and there is no option to run it from its own battery. Harmar offers only two named base adapters for it, both for Ford trucks, where the standard AL425 has five to choose from. And the docking device that actually grips your chair is not in the box on either model, which is a real second cost, priced on this page so you can see the whole figure before you order.
Look at the standard AL425 instead if your equipment is under 400 lbs., because it costs less and it can take the battery pack. Look at the AL435 if you need a third axis. Look elsewhere entirely if your equipment weighs more than 450 lbs.
Straight talk
Is it right for you?
A good fit if you
- You want the wheelchair or scooter to travel inside the vehicle rather than outside on a platform
- Your equipment weighs 450 lbs. or less
- Your power wheelchair is heavier than the 400 lbs. the standard AL425 carries
- You want the lift to do the lifting and the turning, rather than swinging a boom by hand
- You drive a van, an SUV or a truck
Look elsewhere if you
- Your equipment weighs more than 450 lbs.
- You want the device carried outside on a platform behind the vehicle
- You have no room inside the vehicle for the chair or scooter once it is loaded
Specifications
Specifications are the manufacturer's own published figures for this model.
Fitting it to your vehicle
A hoist lift is installed on the vehicle rather than unpacked and used. This is what that involves.
The lift mounts to the floor of the vehicle on a base adapter, and Harmar puts a universal base adapter in the box. The arm sits between 31.5" and 46.5" high and the length adjusts from 26.25" to 33.5". The docking device that holds your equipment is not included, because the right part depends on the chair or scooter it has to lift.
Before you order
Work through the steps beside this panel. They settle how the lift mounts, which hitch adapter your vehicle takes and whether your state requires a plate riser, so the parts that arrive are the parts your vehicle takes.
Getting it here
Every order ships from the manufacturer to the address you give us. The carrier arranges a delivery window with you in advance. Installation is arranged separately, and we will point you at what your vehicle needs before you order rather than after.
Warranty and returns
The Harmar AL425HD is covered by Harmar's own limited warranty, published by Harmar as follows.
| What is covered | How long |
|---|---|
| Vehicle lift | 3 years |
What is not covered
The three year term runs from the date of installation and from the date of retail purchase. Harmar states that the warranty is transferable only where the application is approved by Harmar's Compatibility Calculator, so a lift fitted to a vehicle that was never checked may not carry a transferable warranty.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with Harmar for you and get the covered part sorted out rather than handing you a phone number. The base warranty covers parts, so ask us about service and labor options when you call.
Returns
A hoist lift cannot be returned. It is fitted to your vehicle, wired into it and in many installations drilled into it, so once that work is done the unit is matched to one car and it has no second life on the shelf. This is exactly why the steps beside this panel exist. They settle the mounting, the adapter and the plate riser before you order.
A unit that arrives damaged or faulty is a different matter and is covered above. Contact us before anyone begins the installation.
See our return policy for complete details.

Common questions
The lift and a universal base adapter, which is the plate it bolts to inside your vehicle. The docking device that holds your wheelchair or scooter is not in the box, because the right part depends on the equipment it has to lift. You choose that in the step headed Your docking device.
It carries 450 lbs. where the AL425 carries 400 lbs. Its arm sits higher, between 31.5" and 46.5" rather than 30" to 41", and its length adjusts from 26.25" to 33.5" rather than 23.5" to 33.5". Everything else about how the two lifts work is the same. This model takes a different set of base adapters, and they are the ones listed in the step headed Base adapter.
Because the lift cannot hold your equipment without one, and Harmar does not put one in the box. If you are replacing an older lift and keeping the device you already have, choose I already have a docking device and nothing is added to your order. If you do not know which one you need, choose I am not sure which one I need, tell us your wheelchair or scooter in the last step, and we match the part for you before your order ships.
The base adapter is the plate the lift bolts to inside the vehicle. Harmar includes the universal one and it suits most vehicles. Two named adapters are offered for this model, both for Ford trucks, and they are listed in the step headed Base adapter. A named adapter replaces the universal one and is charged at list price.
Either. The post is offset so the wheelchair or scooter can be unloaded at the side of the vehicle rather than directly behind it, and Harmar sells a driver side upgrade for this model. It is in the step headed Accessories.
Yes. Harmar does not offer the battery pack on this model, so the AL425HD is wired to the vehicle rather than run from its own battery. The standard AL425 is the model that takes the battery pack.
The boom lifts and rotates under power from a weather-resistant hand control. If you would rather not be tethered to the vehicle by a cord, the wireless remote is in the step headed Accessories.
No. A vehicle lift is bolted into your vehicle and wired into it, so it is fitted rather than unpacked and it cannot be sent back. That is why we check the vehicle and the equipment you give us against Harmar's published capacities before anything ships.

Documents
The base adapter is the plate the lift bolts to inside your vehicle. A universal one comes in the box at no charge and it suits most vehicles. Some vehicles need the adapter built for them instead, and where yours does, the part below replaces the universal one rather than adding to it. If you are not sure, leave it on the included part and we confirm it against the vehicle you give us before your order ships.
1 · Base adapter
The docking device is the fitting that grips your wheelchair or scooter so the lift can raise it. The manufacturer does not put one in the box, because the right one depends on your equipment, and the lift cannot carry anything without it. Most chairs and scooters lift either by the centre seat post or by the four post seat frame. Choose the one that matches yours and we confirm the exact part with you before your order ships.
2 · Your docking device
This answer decides how much you have to work out yourself. A hoist lift is wired into the vehicle and bolted to a base inside it, so it is fitted rather than unpacked.
These fit this model. Choose any you want and they are added to your order with the lift.
4 · Accessories
Last thing, and it is the one we act on rather than you. Tell us the vehicle and the scooter or power chair, and we check what you tell us against Harmar's published capacities before your order ships. All of it is optional.
5 · Your vehicle and your equipment
One step could not be settled from your measurements.
Send those three figures to a specialist and they will confirm the part for your vehicle. Call 1-855-HIELINE if you would rather talk it through.
