Car jacks are essential tools for lifting a vehicle when changing a tyre, inspecting the wheels or carrying out certain maintenance work. Different jacks are designed for different vehicles and situations, so choosing the right one matters.
Whether you want a compact jack to keep in your boot or a stronger hydraulic jack for regular garage work, the vehicle’s weight, ground clearance and intended use should all be considered.
What Is a Car Jack?
A car jack is a lifting device that raises part of a vehicle off the ground. It allows you to remove a wheel or access certain parts of the vehicle for maintenance.
The jack should be placed only at the vehicle’s designated lifting points. Your owner’s manual can show you where these points are located.
Types of Car Jacks
The most common types include:
- Scissor jacks
- Trolley or floor jacks
- Bottle jacks
- Electric jacks
- High-lift jacks
Each has advantages and limitations.
Scissor Jack
A scissor jack is the compact mechanical jack commonly supplied with many cars. It uses a screw mechanism to raise the vehicle when you turn the handle.
Its biggest advantages are its small size and portability, making it useful for keeping in the boot for emergencies.
A scissor jack is particularly suitable for changing a flat tyre when you need to get back on the road.
Trolley or Floor Jack
A trolley jack, also called a floor jack, uses hydraulics and wheels to move underneath the vehicle.
It is generally more convenient for regular maintenance because it can be positioned easily and lifted with repeated pumping of the handle.
A trolley jack can be useful for jobs such as:
- Changing wheels
- Brake inspection
- Suspension work
- General garage maintenance
It is heavier and takes up more storage space than a standard scissor jack.
Bottle Jack
A bottle jack has a compact vertical design and uses hydraulic pressure to lift the vehicle.
It can provide substantial lifting capacity relative to its size, making it useful for some SUVs, trucks and other vehicles with sufficient ground clearance.
However, its height and small base mean you need to make sure it fits correctly underneath the vehicle and is positioned on a firm, level surface.
Electric Car Jacks
Electric car jacks use an electric motor to raise the vehicle, usually powered through the vehicle’s electrical system.
They can be convenient for drivers who want less manual effort when changing a tyre.
Before buying one, check its lifting capacity, minimum and maximum height, power requirements and compatibility with your vehicle.
Don’t assume an electric jack is automatically safer simply because it does the lifting for you.
How Much Weight Can a Car Jack Lift?
Every jack has a maximum load rating.
Choose a jack with a suitable capacity for your vehicle rather than selecting one based purely on price or size.
You should also check whether the manufacturer’s stated capacity is appropriate for the way you intend to use the jack.
For an SUV, pickup or larger vehicle, a jack designed only for a small passenger car may not be suitable.
Check the Ground Before Using a Jack
Where you position the vehicle is extremely important.
A car jack should be used on firm, level ground where possible. Soft soil, loose gravel, steep slopes or unstable surfaces can make lifting a vehicle dangerous.
If you have a roadside tyre problem, move to a safe location away from moving traffic before attempting to lift the vehicle.
Find the Correct Jacking Point
Do not simply place the jack underneath any convenient part of the car.
Modern vehicles have specific reinforced lifting points designed to support the vehicle safely.
Using the wrong location can damage bodywork, suspension components or other parts underneath the vehicle.
Check your owner’s manual if you are unsure.
Never Rely on a Jack When Working Under a Car
A jack is designed to lift a vehicle. It should not be treated as the only support when you need to work underneath it.
If a repair requires you to get underneath the vehicle, use appropriately rated jack stands or other approved support equipment after lifting the vehicle.
Never put any part of your body underneath a vehicle supported only by a jack.
Car Jack for Changing a Tyre
For an emergency puncture, the jack supplied with your vehicle may be sufficient if it is in good condition and correctly rated.
Before lifting:
- Park on firm, level ground.
- Apply the parking brake.
- Put the vehicle in the appropriate gear or park position.
- Switch off the engine.
- Secure the vehicle according to the manufacturer’s instructions.
- Locate the correct jacking point.
- Lift the vehicle only as much as necessary.
Keep people away from the vehicle while it is raised.
What Should You Keep With Your Car Jack?
A useful roadside setup can include:
- Car jack
- Wheel wrench
- Spare tyre or approved repair kit
- Wheel chocks
- Gloves
- Torch
- Reflective warning equipment
Check your equipment occasionally rather than discovering that the jack or wheel wrench is missing during a night-time puncture.
Car Jacks for Nigerian Roads
Roadside tyre problems can happen during both city driving and interstate journeys. If you’re travelling from Lagos to Ibadan, Ilorin, Abuja or another city, having the correct emergency equipment in the vehicle can be useful.
If you regularly drive on rough or uneven roads, inspect your jack after use and make sure it remains clean and functional.
Don’t use a jack on loose roadside soil simply because it is the only convenient place to stop. If possible, move to a firm and safer surface.
Signs Your Car Jack Needs Replacing
Inspect your jack before depending on it in an emergency.
Look for:
- Bent components
- Cracks
- Damaged threads
- Hydraulic fluid leaks
- Rust that affects structural parts
- A saddle that does not move correctly
- Difficulty lifting the vehicle
- Slow hydraulic movement
- Missing handles or components
If the jack doesn’t operate correctly while you are testing it, replace or repair it before you need it on the road.
Choosing the Right Car Jack
Think about how you will actually use the jack.
For occasional roadside tyre changes, a compact scissor jack may be convenient.
For regular garage maintenance, a trolley jack can offer easier positioning and faster lifting.
For higher-clearance vehicles, a suitable bottle jack may be an option if its minimum height, lifting range and capacity match the vehicle.
The most important factors are the jack’s capacity, lifting range, compatibility with the vehicle and the conditions in which you will use it.
Car Jacks and Long-Distance Travel
Before a long journey, check that your jack, wheel wrench and spare tyre are all present and usable.
There is little value in carrying a jack that is damaged or too small for the vehicle.
If you’re arranging a family trip, airport transfer or other journey through Travo.ng, making sure your vehicle is prepared before departure can help avoid unnecessary delays along the way.
