With a 4 Ton lifting capacity, this Bottle Jack can lift loads weighting up to 8,000 poundsChange the tires on cars, trucks, and trailers or make repairs to your tractor, combine or hay baler. Small, portable and reliable, this is a great jack to keep nearby for emergency repairs. A cast iron base bears the load and a cleated non-slip lift cap keeps it stable. The hydraulic bypass prevents ram over travel and prevents damage to the Jack. The pump cartridge is replaceable, so you don’t have to replace the entire jack when the hydraulic has been exhausted. With a lift range of 7.75 to 12.75 inches (with the screw lift fully extended), the Black Bull Bottle Jack can get the heaviest of loads into the air and out of the way so you can make the repair and move on to other projects.
