Choosing a professional car jack: a practical buying guide for heavy vehicles

A professional car jack needs to do more than lift a vehicle a few centimetres. In a garage, workshop or business, the key things are whether the jack suits the vehicle’s weight, the space available and the way you carry out maintenance. The wrong choice can lead to instability, damaged sills or a jack that doesn’t provide enough lifting height in practice.

This applies to everything from changing tyres on your own car to daily use with lorries, buses, tractors and commercial vehicles.

Three common pitfalls when choosing a professional car jack

1. Looking only at the maximum lifting capacity

A rating of 5 tonnes or 10 tonnes doesn’t mean every vehicle can be lifted safely in every situation. Weight is often unevenly distributed, and extra loads affect the forces involved. So check both the permitted lifting capacity and the vehicle’s designated lifting points.

A 10-tonne hydraulic jack may be suitable for heavy vehicles, but the ground, the position of the jack and the contact surface are still crucial. Always use suitable axle stands after lifting before working underneath a vehicle.

2. Not comparing the lifting height with the vehicle

A jack may have a high load capacity but still be unsuitable if its minimum height is too great or its maximum height isn’t enough. Measure the available clearance at the lifting point beforehand. A lorry, bus or agricultural vehicle will often need a greater lifting range than a car, too.

Check the full range, for example 222 to 448 millimetres, rather than looking only at the maximum height.

3. Confusing speed with practical usability

A pneumatic air jack may be described as lifting quickly, but it requires a suitable compressor and air connection. Without sufficient air capacity, a 5-tonne pneumatic air jack may not work as smoothly as you expect.

A long handle, adjustable grip or swivel castors are only useful if they suit the space available in your workshop.

Important specifications to check

Load capacity and safety margin

Don’t choose a jack based on the vehicle’s total weight without considering the load on a single lifting point. Check the vehicle’s technical information and allow for any load, attachments and weight distribution.

A heavy-duty vehicle jack for lorries or construction machinery must also stand securely on the floor. A high load capacity won’t make up for soft, sloping or uneven ground.

Lifting range and adjustability

The minimum height determines whether the jack will fit under the vehicle. The maximum height determines whether you’ll have enough room to change a wheel or carry out a repair. An adjustable screw can help you set the final height more precisely, but it doesn’t replace correct positioning.

A garage jack for cars needs different dimensions from a lorry jack. Check the shape and size of the saddle, too, so the contact point doesn’t rest on vulnerable bodywork.

Construction, operation and ground conditions

Look for verifiable features such as:

  • Forged or high-quality steel for load-bearing parts.
  • A wide base to help reduce the risk of tipping.
  • A non-slip saddle with a suitable contact surface.
  • An overload or safety valve on hydraulic models.
  • Controlled lowering.
  • A handle or wheels that suit the space available.
  • Rust protection, especially in unheated garages and workshops.

Only use a car jack on a firm, level surface. Secure the vehicle according to the manufacturer’s instructions, and never rely on the jack alone when working underneath it.

Frequently asked questions about professional car jacks

Which professional car jack do I need for a lorry?

It depends on the weight at the chosen lifting point, the minimum ground clearance and the working height you need. For heavy vehicles, a 10-tonne hydraulic jack may be suitable, while a 5-tonne pneumatic air jack may be a better fit for certain cars, vans and workshops with compressed air. Always check the vehicle documentation and product specifications.

Can I work underneath a vehicle using a car jack?

A jack is designed to lift a vehicle, not to support it for long periods. Once the vehicle is raised, place it on suitable axle stands with sufficient capacity. Work only on a firm, level surface and follow the instructions from both the vehicle and jack manufacturers.

How do I maintain a hydraulic or pneumatic jack?

Keep the jack clean and dry. Before use, check the hoses, valves, welds, wheels and saddle, and look for leaks or gradual lowering. Maintain the hydraulic system on hydraulic models according to the product instructions. A pneumatic air jack also needs a suitable, well-maintained air connection. Stop using the jack if you notice visible damage or unusual behaviour.
