Hydraulic jacks operate on the principle of Pascal's law to multiply force. Essentially, pressure is created when a hydraulic jack's lever is pumped, applying force on the fluid inside a chamber.

Testing revealed it could produce a pressure of 3000 PSI, which would be plenty to move the hydraulic jack even if the hand pump would be needed to finish the job when higher force was required.

These include a heavy-duty hydraulic jack, a torque wrench, wheel chocks, safety equipment — reflective vest, safety glasses and gloves — and a tire pressure gauge.
