Floor Jack vs Trolley Jack: Is There Any Real Difference?

Quick answer: In the floor jack vs trolley jack debate, there is no real difference in the tool. Both names describe a low hydraulic jack on wheels with a long pump handle. “Floor jack” is the usual American term, while “trolley jack” is what UK and Australian makers and regulators call it. Choose by capacity, saddle height and weight, not by name.

This question pops up constantly when you shop across UK and US sites. One listing says trolley jack, the next says floor jack, and the specs look identical. That’s because they are.

Same machine. Two accents.

Floor Jack vs Trolley Jack at a Glance

	Floor jack	Trolley jack
Where the name is used	US and Canada (Arcan, for example)	UK and Australia (Sealey; the ACCC)
Design	Wheeled chassis, hydraulic ram, long handle	Wheeled chassis, hydraulic ram, long handle
Rolls into position	Yes	Yes
Lifts by	Pumping the handle	Pumping the handle
Lowers by	Turning the handle to open a release valve	Turning the handle to open a release valve
Can hold a car up on its own	No, lifting only	No, lifting only
Needs stands before you go under	Yes	Yes

Compare the manuals and the wording barely changes. Arcan’s US manual for its aluminum floor jack says “This is a lifting device only.” Sealey’s UK trolley jack manual says to use the jack for lifting only, not for supporting the lifted load.

Is a Trolley Jack the Same as a Floor Jack?

Yes. Australia’s product safety regulator, the ACCC, defines a trolley jack as a device that raises and lowers part of a vehicle via its chassis. That’s exactly what an American floor jack does.

Some retailers claim one is taller or heavier than the other. I don’t buy it. In practice, those differences come from the individual model you pick, not from whichever regional word the marketing team printed on the box.

What Actually Differs Between Models

This is where I’d spend my attention. Four specs matter.

Rated capacity. The ACCC says to check the label so the jack’s maximum load suits the vehicle you’re lifting. Remember you’re usually raising one corner or one end, not the whole car, but don’t cut it close.
Minimum saddle height. Lowered cars and sporty trims need a low-entry jack. Sealey’s 3000SER, for example, starts at 100 mm (about 4 inches).
Maximum lift height. Trucks and SUVs need more reach. That same Sealey model tops out at 535 mm, roughly 21 inches.
Chassis length and weight. A long chassis reaches central jacking points; the 3000SER’s is 780 mm. Aluminum models are easier to carry to the roadside, while steel ones tend to be heavier and bulkier.

My take: for a typical sedan or small SUV at home, a standard-height jack works fine. A low-profile one is the safer bet if your car sits low or wears a front lip.

How It Compares With Other Car Jacks

Floor and trolley jacks aren’t the only option. Honestly, this is where the real decision usually lives.

Scissor jack (the one in your trunk): compact and light. The ACCC notes the jack supplied with your car is designed only for changing tires.
Bottle jack: a compact vertical hydraulic ram. It packs small and lifts high, but its narrow base and tall starting height make it awkward under many cars.
Floor or trolley jack: wheels and a wide chassis let it roll under the car and stay stable as it lifts, which is why home garages favor it.

The Safety Rules Are Identical

Whichever name is printed on yours, the manuals agree. The ACCC is blunt: never get under a vehicle supported only by a trolley jack. Australian figures it cites put DIY car repair at an average of five deaths and 160 injuries a year.

Here’s the combined advice from Arcan, Sealey and the ACCC:

Work on hard, level ground. Sealey prefers concrete and warns the jack can sink into asphalt.
Chock the wheels, set the parking brake, and put the car in Park or in gear.
Lift only at the points your vehicle maker specifies. Your owner’s manual shows them.
Keep the jack free to roll as it rises and lowers.
Leave about 0.5 m of space between the car and any wall, because a car can tilt while lifted.
Place two rated stands right after lifting. Arcan says not to crawl under while lifting or while placing stands.
Lower slowly by opening the release valve gradually.

Don’t trust bricks or wood blocks either. The ACCC’s guidance says to use proper stands instead. When I picture the worst case here, it’s a block that splits under load with someone’s chest underneath it, which is exactly the scenario these rules exist to prevent.

Which Should You Choose?

Since the names mean the same thing, the trick is to choose by fit:

Pick a low-profile model if your car is lowered, sporty or has low side skirts.
Pick a high-lift, higher-capacity model if you work on trucks or SUVs.
Pick aluminum if you’ll carry it in the trunk or take it to the track.
Pick steel if it lives in the garage and weight doesn’t matter.

Whatever you buy, budget for a matching pair of jack stands at the same time. My rule is simple. A jack without stands is half a kit.

Lifting the car to rotate tires? You may need to recalibrate the tire pressure system afterward, as covered in our guide on how to reset the tire pressure sensor on a Honda CR-V. More tire and brake guides live in Tires, Brakes & Wipers.

Frequently Asked Questions

Why Is It Called a Trolley Jack?

“Trolley” is the British and Australian word for a wheeled cart, and this jack rolls on castors. Americans call the same tool a floor jack.

Is a Floor Jack Better Than a Trolley Jack?

Neither is better, because they’re the same type of jack. Compare capacity, minimum and maximum saddle height, and weight instead.

Can I Leave a Car on a Floor Jack Overnight?

No. Arcan, Sealey and the ACCC all say the jack is for lifting only. Lower the car onto rated jack stands before you leave it or work under it.

Is a Bottle Jack Safer Than a Trolley Jack?

Not inherently. Both are lifting tools only and both need stands. A trolley jack’s wide base and wheels usually make it easier to position correctly under a car.

What Oil Goes in a Floor Jack?

Hydraulic jack oil. Sealey specifically warns against topping up with brake fluid. Check your jack’s manual for the exact type.
