Floor Jacks (Industrial & Scientific)

Select a jack with a lifting capacity greater than the gross weight of the vehicle or equipment on the axle you intend to lift; common consumer and light-industrial capacities range from 1 to 3 tons, while heavier-duty jacks go higher. Verify the vehicle's curb weight and consult the owner's manual for axle loads when in doubt

Main types include hydraulic trolley jacks (common for garages), bottle jacks (compact and high-lift), and low-profile jacks (for lowered vehicles). For general workshop use, a hydraulic trolley jack with appropriate capacity and a low minimum height is typically most versatile

Key safety features include a reliable bypass valve to prevent over-pumping, a wide stable base, a safety saddle or pad that secures under the lift point, a secure release valve for controlled lowering, and compatibility with rated jack stands for use under load

Regularly inspect for leaks, keep moving parts clean and lightly lubricated, check and top up hydraulic fluid per the manufacturer's instructions, bleed trapped air if lifting becomes spongy, and store the jack lowered to protect seals and pistons

Compare rated lifting capacity, minimum and maximum lift height, saddle diameter, build material and weight, overall footprint for stability, and whether the jack meets applicable safety standards (e.g., ASME or CE)

Price can correlate with build quality, materials, and features like faster lift or lower minimum height, but suitability depends on capacity, intended use, and safety features; evaluate specifications and reviews rather than price alone

No — a floor jack is intended for lifting only; always support the vehicle with appropriately rated jack stands placed on solid, level ground before working underneath
