When it comes to car repair or maintenance, the first thing any owner faces is the need to lift the car. Without this, it is impossible to change a wheel, inspect the suspension or carry out work on the exhaust system. But what is the correct name for this device? Many people mistakenly use the term “jack” for all types of equipment, although in fact there is a whole classification of devices with different operating principles and areas of application.
In this article we will look at all types of car lifting devices - from compact manual jacks to professional hydraulic lifts, and we will also tell you which equipment is suitable for the garage and which is used in car services. You will learn not only the names, but also selection criteria, safety rules and common mistakes that can lead to machine breakdown or injury.
We will pay special attention hybrid lifting systems, which combine the functions of a jack and a support stand - these are often overlooked, although they are ideal for long repair work in confined spaces.
1. Jack: the main tool for emergency lifting
Jack is compact device, designed for short-term lifting of a car to a small height. Its main feature is mobility: the jack easily fits into the trunk and is used in road conditions (for example, when replacing a broken wheel). However, it is important to understand that the jack not intended to support the weight of the car for a long time, its task is only to lift the car, after which it is necessary to install support stands.
There are several types of jacks, each of which has its own pros and cons:
- 🔧 Screw (rhombic) jack - the most common in car configurations. Easy to use, but requires a flat surface. Suitable for passenger cars weighing up to 2 tons.
- 💧 Hydraulic bottle jack - more powerful (withstands up to 5–10 tons), but sensitive to horizontal position. Used for SUVs and minibuses.
- 📐 Rack and pinion jack (Hi-Jack) - universal for off-road use, as it can lift the car even on uneven surfaces. Popular among jeepers.
- 🚗 Scissor jack — compact and lightweight, but with a short lift stroke. Often included in the basic configuration of budget cars.
When choosing a jack, pay attention to lifting capacity (must exceed the weight of the car by 20–30%) and pickup height (minimum distance from the ground to the support point). For example, for Volkswagen Golf sedan a 2 ton screw jack is enough, and for Toyota Land Cruiser 200 You will need a 5 ton hydraulic bottle.
⚠️ Attention: Never work under a machine that is supported only by a jack! Even if it is new and certified, the risk of collapse remains. Always use support posts or stands.
2. Lifts: professional equipment for service stations and garages
If a jack is an “emergency” tool, then lifts designed for long and complex work. They are divided into two large groups: single-post and two-post, and also scissor and platform. The main difference from jacks is stability and the ability to fix the car on weight without additional supports.
Let's look at the main types of lifts and their applications:
| Lift type | Load capacity | Benefits | Disadvantages | Where is it used? |
|---|---|---|---|---|
| Two-post electro-hydraulic | 2–5 tons | Versatility, quick lifting, access to all nodes | Requires a flat floor, takes up a lot of space | Car services, tire shops |
| Scissor (park) | 2–3 tons | Compact, low price, easy to install | Limited access to suspension | Garages, car washes |
| Four-post (platform) | 3–8 tons | Maximum stability, suitable for car storage | High cost, difficult installation | Service stations, car dealerships |
| Single-sided (console) | up to 3.5 tons | Space saving, access to one side of the car | Not suitable for symmetrical work | Body shops |
For a home garage, the best choice would be scissor lift with a load capacity of 2.5–3 tons (for example, models from Autoparten or Nussbaum). They take up little space and are suitable for most passenger cars. But for pickups or minibuses You will need a two-post lift with extended arms.
Before purchasing a lift, check the ceiling height in your garage! The minimum height for a two-post lift is 2.5 meters, otherwise the car will not be able to be raised to the desired level.
3. Overpasses and inspection pits: an alternative to lifts
It is not always possible to install a lift - for example, in a rented garage or in a country house. In such cases, they come to the rescue overpasses and inspection holes. Their main advantage is the absence of the need for electricity or hydraulics, as well as lower cost.
Let's look at the pros and cons of each option:
- 🏗️ Stationary overpass - a concrete or metal structure built into the garage floor. Plus: maximum stability. Disadvantage: complexity of installation and impossibility of transfer.
- 🚛 Mobile overpass - prefabricated metal structure (for example, Trek overpass). Plus: can be moved and stored when folded. Disadvantage: limited load capacity (up to 2 tons).
- 🕳️ Inspection hole - a classic solution for garages. Plus: full access to the bottom of the car. Disadvantage: risk of groundwater flooding and the need for ventilation.
When constructing an inspection pit, consider the following nuances:
depth must be at least 1.2–1.5 meters (so that you can stand at full height),
width - at least 80 cm (for comfortable movement),
walls must be reinforced with brick or concrete.
⚠️ Attention: If your region has a high groundwater level, the inspection hole must be waterproofed with bitumen mastic or liquid rubber. Otherwise, it will constantly flood, and the metal parts of the car will begin to rust faster.
How to make a mobile overpass with your own hands?
To make a mobile overpass you will need:
1. Channel or profile pipe 50×50 mm (for the frame).
2. Sheet metal 3–4 mm thick (for flooring).
3. Hinges and latches for folding.
4. Paint for metal (for protection against corrosion).
Assembly takes 1–2 days, and the cost of materials does not exceed 5–7 thousand rubles. The main thing is to correctly calculate the angle of inclination (no more than 15°) so that the car does not move when climbing.
4. Support posts and safety stands: why can’t you do without them?
Even the most reliable jack or lift does not guarantee 100% safety. Must be used for insurance support posts (or "goats"). They take on the weight of the car after lifting and prevent it from falling if the jack breaks or falls off the lift.
Main types of support posts:
- 🔺 Triangular posts - the simplest and cheapest. Suitable for short-term work (for example, changing a wheel).
- 🟥 Adjustable racks with trapezoidal support - universal for different body types. The height can be adjusted (for example, models Stahlwille or Hazet).
- 🟨 Jack stands (hybrid) — combine the functions of lifting and support. Convenient for working alone.
When installing racks, observe the following rules:
Distance between posts must be at least 50 cm from the lifting point.
Support platform the rack must touch body strength element (threshold, side member), and not a plastic bumper or bottom.
Rack height after installation it should be 2–3 cm below the lifting level (for insurance).
Make sure the jack is on a level surface
Place rubber pads under the racks (so as not to scratch the body)
Check the stability of the racks before climbing under the car.
Use at least two racks (even for a passenger car)

5. Specialized devices: for complex tasks
Sometimes standard jacks and lifts are not enough - for example, for lifting a car with damaged suspension or for working with frame truck. In such cases, specialized devices are used:
Transmission jacks - designed to lift the gearbox or engine when removing them. They have an extended platform and adjustable height. Popular models: Ombra OHT203 (load capacity 2 tons) and Autoparten AT-3202 (3 tons).
Pneumatic bags — used for lifting vehicles with minimal ground clearance (for example, sports cars) or in off-road conditions. Powered by a compressor, they can lift up to 5 tons (for example, Air Lift Jack).
Mobile lifting platforms - used in car tow trucks or for moving faulty cars. For example, platform "Lavka" allows you to load a car onto a tow truck without using a winch.
For owners classic cars (for example, VAZ 2101–2107) are relevant jacks with adapters for old jacking points, since standard modern jacks may not be suitable due to the characteristics of the body.
Air bags are the only way to safely lift a vehicle on sandy or marshy surfaces where traditional jacks fail.
6. How to choose a lifting device: step-by-step guide
To avoid making a mistake with your choice, follow this algorithm:
- Determine the purpose of use:
- For emergency wheel replacement — a fairly compact jack (screw or scissor).
- For regular repairs in the garage — you need a lift or overpass.
- For professional service station - only certified two-post lifts.
- Consider the weight of the car:
- Passenger cars (up to 2 tons) - jack for 2–2.5 tons, lift for 2.5 tons.
- SUVs and minibuses (2.5-3.5 tons) - 5-ton jack, 3.5-4-ton lift.
- Trucks and buses (from 5 tons) - only hydraulic lifts or pneumatic systems.
- For modern cars (for example, Hyundai Solaris) standard jacks are suitable.
- For older models (eg Mosvich 2141) an adapter may be required.
- For sports cars (eg Porsche 911) low profile jacks are needed.
Don't forget about brand and certification. Avoid cheap Chinese jacks without markings - they often break under load. among trusted manufacturers: Stahlwille (Germany), Hazet (Germany), Ombra (Italy), Autoparten (Russia).
7. Common mistakes and safety rules
Even experienced motorists sometimes violate the rules for lifting a car, which leads to accidents. Here are the most common mistakes:
- 🚫 Climbing on soft ground — the jack falls through, the car moves off. Solution: use a durable backing (board or metal sheet).
- 🚫 Jacking up by a bumper or plastic body kit - the body is deformed. Solution: look for special jacking points (indicated in the car manual).
- 🚫 Working under a machine without safety stands - risk of fatal injury. Solution: Always use at least two supports.
- 🚫 Exceeding the lifting capacity of the jack - leads to mechanism failure. Solution: take a jack with a margin of 20–30%.
Before climbing, be sure to:
secure the car with the handbrake,
put chocks under the wheels,
remove the key from the ignition switch (so that you don’t accidentally turn on the gear).
⚠️ Attention: If you are lifting a car on a slope (for example, on the side of the road), place the jack on the side of the lift, and place the largest possible supports (for example, bricks or special “shoes”) under the wheels on the opposite side.
FAQ: Frequently asked questions about car lifting
Can a jack be used for long-term repairs?
No, the jack is intended for short-term lifting only. For jobs lasting more than 10–15 minutes, be sure to use support posts or a lift. Even if the jack seems stable, there is still a risk of it breaking.
How to lift a car if the jack does not reach the jacking point?
In this case you can use spacer made of durable material (for example, a wooden block or a metal plate). The main thing is that the spacer is level and does not slide. For low vehicles (eg sports cars) special low-profile jacks are sold.
What is the difference between a hydraulic jack and a screw jack?
A hydraulic jack uses fluid (oil) pressure to lift more weight with less effort. The screw jack uses a mechanical drive (threaded screw), it is easier to maintain, but requires more physical effort. Hydraulic jacks are more powerful, but are sensitive to horizontal position and require periodic oil changes.
Is it possible to make a lift with your own hands?
Yes, but this requires experience working with metal and compliance with safety regulations. The simplest option is scissor lift from channels and a hydraulic jack. However, homemade designs are rarely as reliable as factory ones, so they are not recommended for use on heavy vehicles or professional repairs.
Which jacks are suitable for SUVs?
For SUVs (eg. Toyota Land Cruiser, Nissan Patrol) are optimal: hydraulic bottle jacks (load capacity from 5 tons), rack and pinion jacks (Hi-Jack) - for off-road use, air bags — if you need to lift the car on loose soil.
Please note pickup height - for SUVs it is greater than for passenger cars.
