Air Hydraulic Jacks - Buyer's Guide
24 de enero de 2016
Whether you need to lift a classic car or a 60-ton truck or even a bus, to work both quickly and safely, you need to have the right equipment. Here is the 6-step guide to make the right choice:
Step 1: Identify which type of vehicle you need to lift
To know the required lifting capacity, check the weight of the vehicles you are working on.
On the market, you will find different jack types with different capacities:
- For light vehicles (cars, SUV, pick-up trucks…) use a trolley jack, with a lifting capacity varying between 2 and 3 tons.
- For heavy vehicles (trucks, buses, agricultural & construction vehicles, aircrafts, reach stakers…), use an air hydraulic jack with a lifting capacity that can vary from 30 tons to 100 tons, depending on the manufacturer and the model.
- The lifting capacity of an air hydraulic jack varies for each lifting step : For a 50-ton air hydraulic jack, depending on the lifting height required, the lifting capacity varies between 15 and 50 tons.
- When using an air hydraulic jack, you don't lift 100% of the vehicle's weight, but between 1/4 to 1/2 of the vehicle (e.g. to change front wheels) and 1/4 of the vehicle. Choose your equipment accordingly.
Step 2: Make sure your hydraulic jack will fit the height requirements
The free working space below vehicles is getting smaller every day. This is why you can now find more compact air hydraulic jacks, also called “low profile", that can fit into the smallest of areas.
Some other hydraulic jacks will come with extensions, enabling you to extend the maximum height for specific applications.
- 30T Low profile version for buses and low profile trucks
- 50T, 80T and 100T model up to 24 in / 610 mm high extensions included
Step 3: Check the available air pressure
Before buying your equipment, ensure that your airline set up will cover the requirements. This information is provided by the manufacturer, you can find it in the operator manual or in the technical specification sheets.
| Air Hydraulic Jack Model | Air Pressure Required |
| 30, 50, 80 Tons models | 116-174 PSI / 8 - 12 bars |
| 100 tons model | 130 - 174 PSI / 9 - 12 bars |
Step 4: Identify your usage
Step 5: Product quality
Quality and durability are not just here for fun. It is to ensure your safety and to enable you to do the job when you need to. In America and Europe, the main certifications are the CE and ASME certifications. Some independent organisms, such as TUV, also exist. Make sure your hydraulic jack is certified by one of them.
Step 6: Test the ergonomics
