HDS-18EA: aligning a truck without ever taking the weight off its suspension

The reason the HDS-18EA is an alignment lift rather than a four-post lift with a longer runway comes down to two pieces of hardware, and both exist to keep the vehicle sitting on its own springs while you work.

The rear slip plates are free-floating and run on multiple casters, so the back axle can settle sideways as the geometry is adjusted instead of fighting the runway. The front end sits on galvanised turn plates dropped into recessed pockets, so they are located for you rather than shuffled into place by eye. The alternative — jacking each wheel to free it — unloads the suspension and lets the tyre sidewalls relax, and you end up measuring a car that is not standing the way it stands on the road. On a 18,000 lbs truck, with springs that heavy, that difference is not subtle.

Those pockets also take 3D alignment pads, so a shop adding camera-based equipment later is not fighting the lift to do it.

Will It Fit?

This is a long machine, and the length including ramps is the figure that surprises people. Measure the bay before you order.

• Floor length. 312 3/4" (26 ft.) overall including the ramps, or 257" (21.45 ft.) without them. The extended approach ramps are deliberately long — more on that below — but they occupy floor.
• Floor width. Overall width is 153 1/2" (12.75 ft.), with 133 1/2" (11.125 ft.) between the columns.
• Drive-through clearance. 109" (9 ft.). Check this against the widest vehicle you intend to drive on.
• Runways. 257 1/2" (21.45 ft.) long, 22" (1.80 ft.) wide, set at 40" or 45 1/4" apart (3.35 ft. / 3.75 ft.).
• Rise. Minimum height is 10 1/2" (0.875 ft.); maximum rise under the runway is 59" (4.90 ft.) and maximum lifting height is 71 1/4" (5.95 ft.). A lift cycle takes 75 seconds. Your ceiling needs to clear the top of the vehicle at full rise, not the top of the lift.
• Power. 220 VAC / 60 Hz / 1 Ph.

Confirming the ceiling, the floor area and the supply is the buyer's responsibility, and a lift that does not fit the building is not a warranty matter. Our record does not state a required concrete thickness or strength for this model; the figure is in the installation manual linked on this page, and we will confirm it in writing before you order if you ask. Note also that the runways are the reference surface for an alignment — a floor with a slope in it is a real consideration, which is exactly why the safety ladders are adjustable.

The parts that wear, sized up

Four-post lifts are undone by their cables and the sheaves those cables run over, so this is where to look when comparing machines. The sheaves here are 12" in diameter, turning on 4" diameter axles. Diameter matters because a cable bent around a small radius fatigues where it flexes; a bigger wheel is a gentler bend and a longer-lived cable. Every sheave and axle has a grease nipple, so the maintenance that is needed can actually be done.

The cables themselves are 1/2" diameter, 6 x 25 construction, in stainless steel — four of them, internally routed inside the columns and runways along with the airlines and safety latches. The open side of each column means you can still see the cable to inspect it. Everything else is inside a flexible, non-conductive protective conduit, which on an alignment lift matters more than it sounds: this is the lift that gets wash-down, brake fluid and tyre soap on it all day.

Locks that do not depend on anyone remembering

Spring-loaded safety locks engage automatically as the lift rises, with multiple adjustable locking positions so you can pick a working height instead of accepting one. Releasing them is a push-button pneumatic operation acting on all four columns at once. Behind that sits a secondary lock system on constant guard: it watches for cable slack, and if slack exceeds the operating parameters it engages instantly and shuts the power unit down until the cause is found. The single hydraulic under-runway cylinder carries an integrated flow restrictor, so a burst hose produces a slow descent rather than a fast one.

Perfect For

• Truck and fleet alignment bays — this is the largest-capacity alignment lift in the range.
• General workshops with one bay to spare, where the same lift has to align a heavy pickup and then service a low sports car.
• Tyre and suspension specialists adding alignment work to an existing service list.
• Shops planning 3D alignment equipment, given the recessed turn-plate pockets are built for it.

What's in the Box

From this product's own feature list: multi-caster slip plates, spring-loaded automatic safety locks, four stainless steel lifting cables, the 12" diameter cable sheaves with grease nipples on every sheave and axle, the single hydraulic under-runway cylinder with integrated flow restrictor, push-button pneumatic lock release, the secondary lock system, 12" x 12" base plates and enclosed cables, airlines and safety latches. Rolling jacks are listed as optional, not included — if you intend to do wheel and brake work as well as alignment you need two of them, and that is a conversation to have before the order goes in rather than after.

Specifications

Certification, and the distinction worth knowing

This model is stated to be CE approved and certified, meeting or exceeding the standards prescribed by European Standard EN-1493. That is a real and useful thing, and it is what our product record holds for this lift.

It is also worth being precise about what it is. A European conformity marking is, in the main, a manufacturer's declaration against European directives. It is not the same document as a North American third-party lift safety listing, where an independent body examines the design and lists the product, and it is not a substitute for one. Insurers, fleet policies and some local code officials ask specifically for that second kind. Our record for this model does not hold such a listing — which is a statement about our data rather than a verdict on the lift. If your insurance, your inspection regime or your workplace rules require it, ask us in writing before you order and we will get a written answer from the manufacturer.

Shipping and delivery

Freight only, to the lower 48 states, quoted live at checkout against your address — that is why no shipping figure is written into this page. The shipping crate is 265" x 26" x 38" and the shipment weighs 6,790 lbs, so plan the approach to your building as well as the space inside it.

The carrier delivers kerbside and no further. Settle unloading in advance: a forklift or telehandler at your premises, or collect it from the freight terminal, which for a crate of this length is often the practical answer. A residential address carries a residential fee. Warehouse pickup is available for this brand. Inspect the shipment before signing and write any damage onto the bill of lading at the time — a clean signature makes a later claim extremely difficult.

Warranty

The warranty document that applies is linked on this page; read the term and the exclusions there rather than relying on any summary. Whatever it says, one rule always applies: do not disassemble a component you intend to claim on. Photograph the fault, leave the assembly as it is, and speak to us before touching it. A stripped part is the most common way a claim that would have been paid stops being payable.
