JET 456612 AHJ-12 Air Hydraulic Bottle Jack
JET 456612 identifies the AHJ-12 twelve-ton air/hydraulic bottle jack with a molded carrying case. It combines air-powered pumping with a hydraulic lifting mechanism. Minimum height, overall raised height and piston travel must be checked separately for the intended lifting point.

Before ordering
Verify rated load and height dimensions against the manufacturer's current data, lifting-point geometry and available air supply. The listed piston lift does not by itself explain the full overall height range; check extension configuration. Follow permitted operating orientation and support instructions. A lifting jack is not a substitute for appropriate load-support equipment.
Product questions and answers
Does air pressure replace the hydraulic mechanism?
No. This is an air/hydraulic jack: the air supply operates a pump, while the jack uses hydraulic lifting.
Is the nine-inch overall height difference all piston travel?
No. Piston lift is separately listed as 4-1/2 inches. Confirm the manufacturer's extension configuration rather than equating these dimensions.
Can the jack alone support a load for work underneath?
Do not treat a lifting jack as support equipment. Use appropriate rated supports and follow the equipment and load manufacturer's instructions.
