What are the options for household car jacks?
2 Answers
Household car jacks have the following options: 1. Rack and pinion jack: This type of jack is the most common vehicle tool. The rack and pinion jack consists of three parts: the rack, the gear, and the rotating mechanism. It relies on the rotating mechanism to rotate the rack, lifting the jack's support area to raise the vehicle. It is compact and easy to store. However, its drawbacks are also obvious: it cannot support too much weight. There are two structures of rack and pinion jacks: the herringbone structure and the diamond structure. 2. Screw jack: The screw jack relies on its own thread structure to self-lock and support the vehicle, and its supporting weight is much greater than that of the rack and pinion jack. However, the lifting efficiency of this jack is relatively slow, but it descends quickly, so safety must be noted during use.
Having driven a family sedan for years, I've learned that choosing the right jack is crucial. I highly recommend scissor jacks—they're compact, lightweight, and take up minimal trunk space while being easy to move. Opt for a capacity of at least 1.5 tons to match your vehicle's weight, which is generally sufficient for sedans. Hydraulic jacks may be stable but are bulky and heavy, making them inconvenient for household use. Safety-wise, always remember: jacks are for lifting only—always use them with jack stands to prevent dangerous slippage. I bought a mid-priced brand set online three years ago, and it's held up well. For maintenance, periodically test the lifting mechanism for smooth operation and wipe it clean after use before storing. Don’t skimp on budget; better quality ensures longevity. When changing tires, park on level ground, engage the parking brake, and shift to 'P' for peace of mind. Carrying a lightweight jack on long trips is incredibly practical—it’s a real confidence booster.
