Where should the jack be placed to lift a car?

A jack should be placed on the raised position of the chassis near the tire. A jack is a lightweight lifting device that uses a rigid lifting component as its working mechanism to lift heavy objects within a small stroke range through a top support seat or bottom support claw. Jacks are primarily used in factories, mines, transportation sectors, and other industries for vehicle repairs, lifting, and support tasks. Steps for using a jack: 1. Before using the jack, ensure the car is parked and the engine is turned off. Place a safety warning triangle 50 to 150 meters behind the vehicle. 2. Align the jack with the support point under the car's chassis. 3. Connect the accompanying wrench and sleeve to the back of the jack, then rotate it to adjust the jack's height. Avoid applying excessive force during operation, as this may cause the jack to deform.
When I changed the tires myself last time, choosing the correct jack position was crucial. You need to place the jack on the sturdy points of the vehicle's frame under the car, such as the metal protrusions or small notches near the wheels. If you place it incorrectly, like on the fuel tank or plastic parts, the car could collapse or shake and fall, which is extremely dangerous. I checked the vehicle manual, which marks the lifting points for each wheel—usually a bit behind the inner side of the front wheels and in front of the rear wheels. These spots are designed to bear the entire weight of the car. Beginners should practice on level ground first, ensuring the jack is stable before proceeding to avoid injury to themselves or the car. Also, when changing tires, engage the handbrake and set up a warning triangle for safety. In short, identifying these points correctly can prevent accidents and repair hassles, making the process much smoother.
