The important role of a horizontal jack is to lift and lift heavy objects. Typically, a dedicated jack will be prepared for the car, and car maintenance personnel must also use the jacking equipment to provide a safe space for the operator. What are the precautions when using a jack to change tires?
1. Pay attention to the specifications of the custom jack
The car adopts the original jack, and its lifting range exceeds the weight of the vehicle. If the original jack is damaged, you will need to purchase a jack that can withstand more than the vehicle's weight. Make sure the stand is secure in use to prevent unbalanced stand from tipping and collapsing. The lifting range of the original jack of the car is usually within 1.5T. Most of the domestic jacks are small and convenient gear jacks. A gear jack is a hollow jack, but with a limited load.
2. Choose the correct support point
Be sure to choose the correct support point, usually on the cross member with the gears on the underside of the car, which is easy to find. The hollow jack stand must be straight and stable. Choose a hard surface to prevent the jack from digging deep into the pavement, causing uneven stress and unbalanced support. There are special jack support points at the bottom of the vehicle. These vehicle operating instructions contain detailed instructions for the use of the jack. Read ahead of time to ensure the correct mode of operation. The special jack support point of the general family car should be located 20cm behind the front tires on both sides of the vehicle.
3. Safety warning signs
On the one hand, there are certain safety hazards when using the jack, and on the other hand, avoid being disturbed by others when changing tires. Therefore, place a safety warning sign after the car is installed and then remove it after changing the tire.
4. Jacks are always held
Jacks come in many types and sizes. The original jack bearing capacity of different vehicles is different. Take it with you and don't lend it to others.
Although a recumbent jack is a small object, it can make a big difference when it matters. Correct operation is necessary to ensure safe use.
