AMGO RJ-6A Rolling Bridge Jack — the air-pumped version
The RJ-6A is a 6,000 lbs rolling bridge jack for four-post and scissor lifts, and the single thing that separates it from its own sibling is the pump. Where the hand-pumped model asks a technician to stand and stroke a handle until the wheels clear, the RJ-6A runs off shop air through a pneumatic hydraulic pump and completes its lift in 22 seconds. If you already have an air line at the bay, that is the whole argument for spending the difference.
It is rated for use under lifts up to 12,000 lbs capacity, which covers the great majority of four-post storage and service lifts and most scissor lifts in a general repair shop. Everything else about it — the floating rolling design, the low-profile body, the adjustable arms — is shared with the rest of the family. The pump is the upgrade.
Why the pump choice actually changes the job
A bridge jack is not lifted once a day. It is lifted, dropped, rolled along the runways and lifted again, several times per vehicle, on wheel and brake work. That is why the difference between an air pump and a hand pump is not a convenience feature but a throughput one: the hand you would spend on a pump handle is a hand free to steady the vehicle or position an adapter, and a jack that rises in 22 seconds without effort is a jack that gets used properly instead of being nudged just high enough to save pumping.
The trade is that the RJ-6A needs air. It runs on a compressed air supply — the specification sheet lists an operating air pressure of 0.8 Mpa — so a bay with no air line, a mobile setup, or a home garage without a compressor is a case for the hand-pumped model instead. That is a real limitation and we would rather say it here than have you discover it in the crate.
Will It Fit Your Lift?
A bridge jack is bought for a lift you already own, so fitment is the first question, not the last:
-
Runway spacing: the extendable lower sliding assembly fits widths between runways from 33 11/16" to 52 13/16". Measure your own lift's inside runway spacing before ordering — do not assume from the lift's advertised capacity.
-
Lift capacity: intended for four-post and scissor lifts below 12,000 lbs capacity.
-
Reach: arm pads reach from 33 3/16" to 53 3/8", which is what determines whether the pads meet the vehicle's designated lifting points rather than something you would rather they did not touch.
-
Jack width: 20" overall.
-
Rise: 17 3/4" of lifting height without adapters, 21 3/4" with them.
-
Air supply: a compressed air line at the bay.
Checking the lift the jack has to live on is the buyer's responsibility, and it is a five-minute measurement that prevents a freight return. If you are not certain what your runway spacing is, tell us the lift make and model and we will work it out with you before you order.
Adapters are the part people forget
The jack comes with 1.5" and 2.5" stackable extension adapters and a rubber pad assembly as standard. That matters because chassis heights vary far more than lift heights do: a modern crossover with underbody trays and a lowered coupe need very different stack-ups to reach a solid lifting point, and a jack that arrives without adapters is a jack that needs a second order before it can be used. Here they are in the box.
The arms adjust for position too, so the pads can be moved onto the manufacturer's designated support point rather than the nearest convenient piece of underbody. On unibody vehicles that distinction is the difference between a lifted car and a bent sill.
Locks, rolling and the guardrail
The manual safety lock offers two lock positions, which is a working-height choice rather than a safety formality — you can set the vehicle at the height that suits the job and the technician instead of accepting whatever height the jack happened to stop at. As with any lift or jack, the load should sit on a lock, not on hydraulic pressure.
The floating rolling design and the ergonomic guardrail are what make repositioning the jack along the runways a one-hand job, and the guardrail doubles as protection for the oil hose — the component most likely to be crushed or dragged when a jack is shoved down a runway by someone in a hurry. Small design point, expensive failure to avoid.
Perfect For
-
Busy tire and brake bays running a four-post lift, where the jack is cycled many times a day and air is already piped to the bay.
-
General repair shops that need wheels-free work from a lift bought for wheels-on work.
-
Storage-duty four-posts in a collector's garage, where a bridge jack turns a parking lift into a service lift.
-
Anyone upgrading from a hand-pumped bridge jack who has decided that pumping is the part of the day they would like back.
What's in the Box
The jack with its pneumatic hydraulic pump, 1.5" and 2.5" stackable extension adapters, and a durable rubber pad assembly. Adjustable arms, the extendable lower sliding assembly and the guardrail are part of the jack rather than extras. We do not publish a separate fastener or fittings list, and we would rather check the current packing list with you than invent one here.

Certification, stated honestly
We do not hold a published third-party safety listing for this jack, so we do not claim one. The distinction is worth understanding: a manufacturer's own declaration that a product meets a standard is a different document from an independent testing body's listing of that product, and some insurance policies, fleet operators and local jurisdictions require the second one specifically. If that applies to your shop, ask us before ordering and we will find out what documentation exists for this model rather than let you assume.
Shipping and Delivery
Bridge jacks ship as freight to the lower 48, with the cost quoted live against your address at checkout rather than estimated in advance. You will need a way to get it off the truck — a forklift, a dock, or an arrangement to collect from one of our warehouses. A residential delivery carries a residential fee.
Look the crate over before you sign for it. Bent arms and a damaged pump are not always visible through packaging, so open it while the driver is there if you can, photograph anything you find, and write it on the bill of lading at the time. That note is what a freight claim rests on.
Warranty
Warranty terms for this model are handled through our warranty claims page, and we will send you the current document before you order if the terms matter to your decision. If a pump or a cylinder fails, photograph it in place and contact us before anything is taken apart — a component that has already been dismantled is generally treated as modified, and that turns a simple claim into a dispute.
