Which Type of Jack to Carry in the Car?
1 Answers
You can carry a rack jack or a screw jack in your car. Rack jacks come in two structures: the A-frame structure and the diamond structure, both of which are common vehicle tools. A rack jack consists of three parts: the rack, the gear, and the rotating mechanism. It relies on the rotating mechanism to turn the rack, lifting the jack's support area to raise the vehicle. A screw jack supports the vehicle by its self-locking threaded structure and can bear much heavier loads than a rack jack. However, this type of jack lifts slowly but lowers quickly, so safety precautions are necessary during use. A jack is a lightweight lifting device that uses a rigid lifting component as the working mechanism to raise heavy objects over a short distance via a top support or bottom claw.
