Tronair 02A7898C0100 – 5-Ton Tripod Jack, Air Pump

The Tronair 02A7898C0100 is designed for safely lifting aircraft during maintenance and inspection procedures. With a 5-ton capacity and an integrated air-operated hydraulic pump, it provides controlled, reliable lifting with minimal physical effort. The spring-loaded casters improve maneuverability around tight hangar spaces, making it ideal for frequent repositioning beneath landing gear and fuselage jack points.

Operators should always confirm that the jack is positioned directly under the aircraft’s approved jack point and that the ground surface is level and stable. Never exceed the 5-ton rated capacity or use the jack for side loading. Users must also verify the hydraulic oil level and check for air leaks before every lift.

The built-in air-driven hydraulic pump eliminates the need for manual pumping, reducing operator fatigue and increasing lift cycle efficiency. This pneumatic design ensures consistent pressure delivery and smooth lifting, especially useful when servicing heavier airframes or performing repetitive jacking operations. The air system also minimizes hydraulic strain, helping extend component life.

Routine maintenance should be performed every 90 days or after 100 lifting cycles, whichever comes first. This includes checking for hydraulic leaks, inspecting the casters, testing the relief valve, and cleaning the exterior of the cylinder. A complete overhaul or seal replacement is recommended annually.

The spring-loaded casters allow smooth repositioning of the jack while preventing unintended rolling when pressure is released. This feature helps maintain stability during setup and teardown in uneven or sloped hangar environments. The springs automatically engage when the jack is lifted off the ground, providing an additional layer of operational safety.

The jack is equipped with an integrated safety bypass valve that prevents hydraulic over-pressurization. If the load exceeds rated capacity, the valve opens automatically to relieve excess pressure, safeguarding both the jack and the aircraft structure. This built-in protection reduces the risk of equipment failure or damage during high-load applications.

Store the jack fully lowered in a clean, dry, temperature-controlled environment. Disconnect air lines, wipe exposed hydraulic components, and cover the jack with a lint-free cloth to prevent dust contamination. The jack should also be cycled monthly to keep seals lubricated and prevent internal sticking.

Slow or uneven lifting, noisy pump operation, or visible oil discoloration are common signs that the hydraulic fluid requires replacement. Tronair recommends changing the fluid annually or any time contamination is suspected. Always use Tronair-approved fluids to preserve warranty coverage.

Check air lines and fittings regularly for leaks and ensure moisture traps are drained to prevent water contamination in the pneumatic circuit. Tronair emphasizes the use of clean, dry air to maintain pump performance and prevent corrosion. Periodic lubrication of air fittings with non-petroleum products is also recommended.

Yes. The 02A7898C0100 is designed to work with Tronair’s range of jack extensions and saddle adapters, allowing maintenance personnel to service different aircraft configurations. Always ensure that the total load rating (including attachments) does not exceed 5 tons, and verify compatibility with the aircraft maintenance manual before use.
