What are the model specifications of hydraulic jacks?
3 Answers
Hydraulic jacks can be categorized into integrated jacks and split jacks. Here is more related information: 1. Integrated jacks: Brands of integrated jacks include Japan's Masada and Germany's EM. Japan's MASADA hydraulic jacks are divided into several types: MH integrated standard jacks, MMJ mini jacks, MH pressure gauge jacks, NPD two-stage jacks, MHC claw jacks, and MYB low-pressure hydraulic jacks. 2. Split jacks: The main brand of split jacks is the American Enerpac jack. A set of split jacks includes: hydraulic, pressure gauge, gauge stand, high-pressure hose, and manual pump. Models include: RC universal jacks, RCS thin jacks, RSM ultra-thin jacks, STC super ultra-thin jacks, CLP thin self-locking jacks, RRH double-acting hollow jacks, CLL self-locking jacks, WR duckbill (expansion) jacks, CLSG large-tonnage single-acting jacks, CLRG large-tonnage double-acting jacks, RCH hollow plunger jacks, etc. 3. Enerpac jacks: American Enerpac jacks are treated with special paint processes, providing excellent corrosion resistance. Enerpac hydraulic jacks are made of high-quality alloy steel, durable, lightweight, and easy to carry. The main specifications of Enerpac hydraulic jacks include: 10 tons, 20 tons, 30t, 50t, 75 tons, 100 tons, 150t, etc.
The model specifications of hydraulic jacks mainly focus on several key points: The lifting capacity is most commonly available in 2-ton, 3-ton, or 5-ton specifications, which indicate the maximum weight they can lift. The lifting height ranges from a minimum of 10-15 cm to a maximum of 30-50 cm, and you should choose based on your car's chassis height. For example, low-profile sedans require jacks with lower heights. In terms of weight, lightweight jacks (8-10 kg) are more portable, while heavy-duty ones (over 20 kg) offer better stability. With years of experience in car repair, I've seen many people overlook these details—for instance, choosing the wrong tonnage can make the car unstable and cause it to fall. Always remember to use safety stands in conjunction with the jack. Additionally, the hydraulic system must be reliable to avoid oil leaks and failure. When selecting a brand, check the material quality and warranty period. Common models like the SATA 2-Ton jack, with a lifting range of 20-38 cm, are ideal for household cars.
When I first started learning car repair, I studied the specifications of hydraulic jacks. Key parameters include lifting capacity – for example, 1 ton is suitable for sedans, while SUVs require at least 2 tons. The stroke range refers to lifting height, with 15cm to 45cm being the most versatile. If the minimum height is too low, it becomes difficult to access the vehicle underside. I once bought a model that was too low and couldn't lift high-clearance vehicles. Weight also affects portability; lightweight models around 10kg are easier to move. Always match the specifications to your vehicle manual – don't skimp on this. My neighbor once used an under-spec cheap jack that caused hydraulic failure and nearly led to an accident. For safety, choose models with dual-lock designs to prevent slippage, and regularly check oil levels to reduce risks. Specifications are printed on the packaging – beginners should prioritize standard 2-ton models.
