Jack stands are an indispensable tool in car repairs, construction sites and mechanical operations, but if used improperly, they can cause serious safety accidents. To ensure safe operation, key details must be checked before each use. We will introduce 5 safety points that must be checked to help you avoid accidents.

1. Check the load-bearing capacity of the jack stands

• Why is it important? Overloading may cause the bracket to deform or break, leading to collapse accidents.

• How to check?

  • Determine the maximum weight capacity of the bracket (usually marked on the side of the bracket).

  • Make sure the weight of your vehicle or equipment does not exceed this limit.

  • Heavy-duty operations (such as truck repairs) should choose industrial-grade brackets (such as models over 5 tons).

2. Check the stability of the bracket and the supporting surface

• Why is it important?  Uneven ground or an unstable stand may cause the device to tip over.

• How to check?

  • Make sure the stand is placed on a hard, flat surface (such as concrete), avoiding soft soil or slopes.

  • Use anti-skid pads or steel plates to increase the contact area and prevent sliding.

  • Make sure the support claws of the bracket are fully extended and the fixing device is locked.

3. Check the integrity of the mechanical structure

• Why is it important? Mechanical wear can reduce the reliability of the bracket.

• How to check?

  • Jack Stand: Check that the piston moves smoothly.

  • Mechanical spiral bracket: Check the threads for wear and check that the handle rotates freely.

  • If cracks, rust or deformation are found, stop using it immediately and replace it.

4. Check whether the locking device is effective

• Why is it important? If the bracket is not locked after bearing the load, it may fall down suddenly and cause danger.

• How to check?

  • Test whether the safety catch or safety pin is secure.

  • After raising the vehicle, test the stability by gently shaking it to make sure it will not accidentally slide off.

  • Avoid performing maintenance work when the device is unlocked.

5. Check environmental safety and operating regulations

• Why is it important? Even if the bracket is intact, improper operation may still cause an accident.

• How to check?

  • Make sure there are no flammable materials, children or pets near the work area.

  • Use secondary supports, such as safety stands or tire chocks, for additional protection.

  • It is strictly forbidden to enter the bottom of the vehicle for work when it is supported only by the jack stand.

The safe use of jack stands is related to the safety of life and property. Be sure to check the above 5 key points before each use. "It is better to spend 5 more minutes checking than to risk an accident!" If you find that the stand has safety hazards, please replace it immediately or contact professional maintenance personnel.
