02-7833-0110 - Tronair 02-7833C0110 – 12-Ton Axle Jack w/Spacers

The Tronair 02-7833C0110 hydraulic axle jack is designed for lifting aircraft at the landing gear during scheduled and unscheduled maintenance. It’s commonly used for brake service, wheel and tire changes, inspections, and other ground-based maintenance tasks. Its 12-ton capacity makes it suitable for a wide range of business and regional aircraft.

Spacer blocks allow technicians to adjust the jack height so the ram sits as close as possible to the aircraft jack point before lifting. This minimizes ram extension, improving stability and reducing side loading during operation. Proper use of spacer blocks is a key safety practice recommended by Tronair.

Yes, this model is designed for use on both nose gear and main gear when equipped with the appropriate adapters. The operating procedures differ slightly depending on the gear being raised, and specific adapter installation steps must be followed. Always reference the aircraft maintenance manual and Tronair instructions before use.

The Tronair 02-7833C0110 uses standard MIL-PRF-5606 aviation hydraulic fluid. Using the correct fluid ensures proper seal performance, consistent pressure, and long-term reliability. Mixing fluids or using substitutes can damage seals and compromise lifting performance.

Tronair recommends performing a functional load test annually. The test should apply a load equal to the jack’s rated capacity plus 10%, without exceeding that limit. Routine load testing helps verify safe operation and identify potential hydraulic or mechanical issues early.

Before use, operators should inspect the jack for loose fasteners, fluid leaks, and proper hydraulic fluid levels. The reservoir vent screw must be opened before pumping, and the jack should always be placed on a hard, level surface. Aircraft wheels not being raised should be securely chocked.

The four-stage ram design allows for a compact closed height while still providing sufficient lifting range when extended. This helps technicians achieve the necessary lift without excessive jack height. It also improves stability during lifting by maintaining a controlled extension profile.

Regular maintenance includes inspecting seals, replacing O-rings when removed, flushing old hydraulic fluid, and keeping the unit clean. Tronair recommends avoiding unauthorized modifications and using only OEM replacement parts. Following the preventative maintenance schedule helps ensure long-term reliability.

Operators should never place hands between the jack pad and aircraft, operate the jack with the vent screw closed, or stack spacer blocks incorrectly. The half-inch spacer block must only be used alone or at floor level, never above other spacers. Ignoring these precautions can lead to equipment failure or serious injury.
