Bottle Jacks

Select a jack with a lifting capacity equal to or greater than the heaviest load you need to lift; common capacities range from 2 to 50 tons for consumer and light-industrial use, and choosing a capacity slightly above your maximum load adds a safety margin

Look for a wide, stable base, a safety valve to prevent overloading, a locking mechanism or catch to hold load if hydraulic pressure is lost, and a rated load capacity clearly marked on the jack

Stroke height (minimum and maximum lift) determines how low the jack can start and how high it can raise a load; pick a jack with a low collapsed height if you need to fit under low-clearance equipment and ensure the maximum lift meets your task requirements

Higher-priced or established-brand jacks often use thicker steel, better seals and valves, and tighter manufacturing tolerances, while budget options can be satisfactory for occasional light use; consider average category pricing (around $70–$80) and user ratings when balancing cost versus durability

Keep hydraulic fluid clean and at the recommended level, bleed air from the system per instructions, wipe off dirt and moisture after use, store upright in a dry place, and inspect seals and screws regularly for leaks or damage

Bottle jacks can lift a vehicle but are not intended as a long-term support; always place properly rated jack stands under the vehicle before working underneath to provide stable, passive support

Check the required lifting capacity, the minimum collapsed height and maximum lift stroke relative to your lifting point, the saddle size and shape for secure contact, and whether the jack's base fits the work surface for stability
