A dolly for car repairs is an indispensable assistant in a garage or car service, which allows you to work comfortably and safely under the car. Without it, it’s hard to imagine changing the oil, repairing the suspension or brake system. However, not all carts are created equal: some are suitable for passenger cars, others can withstand trucks, and others are equipped with additional features such as hydraulic lift or adjustable height.
In this article, we will look at how to choose a dolly for your tasks, what to look for when purchasing, and how to use it correctly so that the tool will last for many years. You will also learn about popular brands, compare models by price and functionality, and receive practical safety tips. If you're just starting to equip your garage or are thinking about upgrading your tools, this guide is for you.
What is a dolly and why is it needed?
Dolly (or rolling jack with trolley) is a mobile device that combines the functions of a jack and a convenient platform for working under the car. Unlike a conventional jack, it allows you not only to lift the car, but also to fix it at the desired height, and then move with her in the garage or workshop.
The main tasks that this tool solves:
- 🔧 Changing oil and filters — convenient access to the pan and drain plug.
- 🚗 Suspension repair — work with levers, shock absorbers, ball joints.
- 🔩 Brake system maintenance — replacement of pads, discs, calipers.
- ⚡ Exhaust system diagnostics and repair — access to the muffler, catalyst, corrugation.
The advantage of a dolly trolley over stationary lifts or inspection pits is its mobility. You can use it anywhere there is a flat surface, and after work you can easily put it in the corner of the garage. In addition, many models are equipped adjustable lift height, which makes them universal for different types of cars - from small cars to SUVs.
If your garage does not have an inspection hole, a dolly with a load capacity of 2 tons will be the best alternative for most passenger cars.
Types of dolly trolleys: which one is suitable for your tasks
All dolly trolleys can be divided into several types depending on the design, load capacity and additional functions. The choice depends on what kind of work you plan to do and with what cars.
Let's look at the main types:
- 🔹 Mechanical trolleys - lift the car using a lever or screw mechanism. Easy to operate, but require physical effort. Suitable for light tasks (oil change, inspection).
- 🔹 Pallet trucks — equipped with a hydraulic pump that facilitates lifting. You can lift the car almost effortlessly. Ideal for regular use in car repair shops.
- 🔹 Height-adjustable trolleys — allow you to fix the platform at different levels, which is convenient for working with cars of different clearance heights.
- 🔹 Trolleys with additional supports — have retractable stops for increased stability. Necessary when working with heavy vehicles (SUVs, minibuses).
- 🔹 Professional trolleys with lift - combine the functions of a jack and a trolley, often equipped with wheels for moving around the workshop.
The trolleys also differ in material of manufacture:
- 🛠️ Steel - the strongest and most durable, but heavy.
- 🛠️ Aluminum - lighter than steel, resistant to corrosion, but more expensive.
- 🛠️ Combined - combine a steel frame and aluminum parts to reduce weight.
Key parameters when choosing a dolly trolley
To avoid making a mistake with your purchase, pay attention to the following characteristics:
| Parameter | Recommendations | For what tasks is it important? |
|---|---|---|
| Load capacity | From 2 to 5 tons (for cars - 2-3 tons, for SUVs - 3-5 tons) | Safety when lifting heavy vehicles |
| Minimum/maximum lift height | Minimum 10-15 cm (for low cars), maximum 50-70 cm | Working with vehicles of different clearances |
| Drive type | Mechanical (cheaper) or hydraulic (more convenient) | Frequency of use and convenience |
| Platform material | Steel (strength) or aluminum (lightness) | Durability and portability |
| Availability of wheels and clamps | Wheels with locking for stability | Safety at work |
Load capacity - the most critical parameter. If you plan to work with crossovers or minibuses, take a cart with a reserve (for example, 3.5-4 tons instead of the minimum 2). A trolley with a load capacity of less than 2 tons is not suitable for most modern cars - even compact hatchbacks often weigh 1.2-1.5 tons, and taking into account the dynamic loads during repairs, a reserve is simply necessary.
No less important is lifting height range. If you have a low sedan (clearance 12-14 cm), the trolley should have a minimum pick-up height of no more than 10 cm. For SUVs, on the contrary, the maximum height is important - in order to comfortably work under the car without bending.
For garage use, a hydraulic trolley with a lifting capacity of 2.5-3 tons with an adjustable height from 10 to 60 cm is optimal.

How to use a dolly trolley correctly: step-by-step instructions
Incorrect use of the cart may result in car crash, body damage or personal injury. Follow this algorithm to avoid errors:
- Vehicle preparation:
- 🚗 Park the car flat hard surface (asphalt, concrete).
- 🔑 Turn off the engine, turn on
hand brakeand put it on transmission (orParkingfor automatic transmission). - 🔧 Place under the wheels stops (shoes) on the opposite side from the rise.
- Cart installation:
- 📏 Find it on the bottom of the car jack points (specified in the instruction manual).
- 🔄 Roll the cart under the car so that the emphasis is strictly under the lifting point.
- ⚠️ Make sure the cart is level and not skewed.
- Lifting the car:
- 🔼 Raise the cart slowly, controlling stability.
- 🛑 If the car begins to move, immediately lower and reinstall the cart.
- Fixation and operation:
- 🔒 Lock the cart in the raised position (if there is a lock).
- 🛠️ Proceed with the repairs, but do not leave the car on the cart unattended.
- 🔽 Smoothly lower the cart, making sure there are no foreign objects under the car.
- 🚫 Do not stand under the car while lowering!

⚠️ Attention: Never work under a vehicle that is supported only by a jack (without a dolly or additional supports). Even if the jack seems reliable, there is a risk of it suddenly lowering due to a malfunction of the mechanism or uneven load.
Common mistakes when working with dolly trolleys and how to avoid them
Even experienced car owners sometimes make mistakes that can lead to accidents or tool failure. Here are the most common of them:
1. Wrong choice of lifting point
Many people lift their car rapids or exhaust system, which leads to body deformation. Always use special jack points (usually they are marked on the side members or indicated in the car manual).
2. Ignoring wheel chocks
If the wheels are not secured, the vehicle may move off the cart when lifted. This is especially dangerous on sloping surfaces.
3. Trolley overload
Lifting a vehicle whose weight exceeds the load capacity of the trolley leads to mechanism deformation or its sudden folding. Always take a tool with a reserve weight.
4. Working on soft or uneven surfaces
The trolley must stand on hard flat surface (asphalt, concrete). Sand, gravel or tiles with gaps may cause it to tip over.
5. Sudden lowering of the car
This may damage the hydraulics or cart mechanism. Lower the car smoothly, controlling the process.
⚠️ Attention: If the cart begins to “sag” under the weight of the vehicle (for example, due to a hydraulic oil leak), immediately lower the car and check the tool. Operating a faulty trolley is extremely dangerous!
Care and maintenance: how to extend the life of your dolly
In order for the cart to serve for many years, it must be properly stored and periodically serviced. Here are the main recommendations:
1. Cleaning after use
Remove from the platform oil, dirt and metal shavingsso that they do not damage the mechanism. Use a rag and solvent (eg White spirit).
2. Lubrication of moving parts
For mechanical trolleys:
- 🛠️ Lubricate screw and nut lithol or graphite grease.
For hydraulic:
- 🛠️ Check the oil level in the hydraulic cylinder (add if necessary).
- 🛠️ Change the oil every 1-2 years (use hydraulic oil I-20A).
3. Storage
Keep the cart in dry place, protected from moisture. If it is steel, periodically treat it with an anti-corrosion compound (for example, WD-40).
4. Check before use
Before each lifting of the vehicle:
- 🔍 Inspect welds on the cracks.
- 🔍 Check it out work of clamps and wheels.
- 🔍 Make sure that hydraulics don't flow.
⚠️ Attention: If the cart has been exposed to rain or high humidity, wipe it dry and lubricate moving parts before use. Corrosion can block the mechanism at the most inopportune moment.
FAQ: Answers to frequently asked questions about dolly trolleys
🔧 Is it possible to make a rolling cart with your own hands?
Theoretically yes, but this is extreme not recommended for safety reasons. Homemade structures often cannot withstand the load, and errors in calculations can lead to the collapse of the car. If your budget is limited, it is better to buy a budget model from a trusted brand (for example, Sorokin or Autoprofi).
🚗 Is a 2-ton trolley suitable for an SUV?
Most likely not. Most SUVs weigh 2.2–2.8 tons, and taking into account dynamic loads during repairs, the margin should be at least 30%. The optimal choice is a trolley on 3.5–4 tons.
⚡ How often do you need to change the oil in a hydraulic trolley?
Depends on intensity of use:
- 🔹 When regular use (daily) - once a year.
- 🔹 When periodic (once a month) - once every 2 years.
- 🔹 If the cart is stored in damp room, the oil may need to be changed more frequently due to condensation.
Use only special hydraulic oil (for example, I-20A or analogues).
💰 How much does a good rolling cart cost?
Prices vary depending on type and brand:
- 🔹 Budget (mechanical, 2 t) - from 5,000 to 10,000 rub. (Sorokin, Autoprofi).
- 🔹 Middle segment (hydraulic, 3 t) – from 10,000 to 20,000 rub. (JTC, Ombra).
- 🔹 Professional (4–5 t, premium brands) – from 20,000 to 50,000 rub. (Kraftmann, Stahlwille).
For home use, a model for 8,000–15,000 rub.
🔧 Is it possible to use a dolly for a motorcycle?
Technically yes, but this inappropriate. Motorcycles weigh little (150–300 kg), and a cart is redundant for them. Better to use special motorcycle jack or motorcycle lift, which takes up less space and is more convenient to use.
