Tronair 02A7919C0100 – 1-Ton & 2-Ton Tripod Jack

The two-stage hydraulic design allows the Tronair 02A7919C0100 tripod jack to achieve significant lifting height while maintaining a manageable closed height for positioning beneath aircraft jacking points. The jack offers a maximum height of over 120”, making it useful for specialized lifting applications involving elevated aircraft structures. The staged ram system also helps deliver smoother lifting control and improved stability throughout the jacking process.

The optional pneumatic pump system helps technicians raise the jack more quickly and with less manual effort compared to hand pumping alone. Tronair specifies that the air pump operates on a 90 to 100 PSI air supply, helping improve efficiency during repetitive maintenance procedures. This can be especially beneficial in busy hangar environments where faster aircraft positioning helps reduce downtime. The hold-to-run air valve also gives operators greater control during lifting operations.

The ram locknut is a mechanical safety device that supports the aircraft if hydraulic pressure is lost during maintenance. Tronair instructs operators to keep the locknut within 1” of the ram while raising or lowering the aircraft to maintain protection. This added safeguard helps reduce the risk of accidental descent during inspections or servicing. Proper use of the locknut is critical for safe aircraft jacking procedures.

The jack is designed for operation across a wide temperature range, allowing it to perform in both hot and cold maintenance environments. Its durable powder-coated finish helps protect structural components from corrosion, wear, and exposure to aviation fluids commonly found in hangars. Heavy-duty wheels also allow technicians to reposition the tripod jack more easily around the aircraft. These features help support long-term reliability in commercial and business aviation maintenance operations.

CE certification indicates that the tripod jack complies with applicable European machinery safety standards and manufacturing requirements. This certification can be especially important for operators, MRO facilities, and aviation organizations working within international regulatory environments. Tronair’s Declaration of Conformity references compliance with European Community guideline 2006/42/EC and EN ISO 12100-1 standards. This helps reinforce confidence in the jack’s safety and operational design.

The Tronair 02A7919C0100 is designed for use with MIL-PRF-5606 hydraulic fluid, an aviation-grade fluid commonly used in aircraft maintenance equipment. This fluid helps support seal compatibility, corrosion resistance, and reliable hydraulic operation across a wide temperature range. Using the specified fluid also helps maintain lifting performance and reduce premature wear on hydraulic components. Tronair further notes that the hand pump assembly documentation includes compatibility with MIL-PRF-83282 fluid.

Routine maintenance includes checking hydraulic fluid levels before each use, lubricating wheels every three months, and performing annual load testing at 105% to 110% of rated capacity. Tronair also recommends periodically extending the ram during low-use periods and applying water-repellent lubricant to protect exposed surfaces from corrosion. Keeping the work area clean and replacing worn seals when necessary can further improve long-term reliability. Preventative maintenance helps ensure dependable lifting performance and safer aircraft servicing operations.

The tripod design helps distribute aircraft loads evenly across three support points during lifting operations. This stable footprint can improve balance and reduce movement while technicians perform maintenance beneath or around the aircraft. Tronair also specifies that the jack should always be used on a hard, level surface to maximize stability and safe operation. Proper positioning is important when lifting aircraft from the fuselage or wing jacking points.

Tronair recommends storing the jack with the ram fully lowered and the reservoir vent screw closed to help prevent contamination and hydraulic leakage. The manual also states that the unit may be stored outdoors when protected with a waterproof tarp or canvas cover. Proper storage helps minimize corrosion and extends the life of hydraulic seals and exposed metal surfaces. These practices are especially important for aviation ground support equipment exposed to changing environmental conditions.

Aircraft tripod jacks are intended for use by trained aviation maintenance personnel familiar with approved aircraft jacking procedures. Improper lifting techniques or incorrect jack placement can lead to aircraft damage, equipment failure, or safety hazards. Tronair specifically states that operators must understand both the jack’s operation and the aircraft manufacturer’s maintenance instructions before use. Proper training helps improve safety, efficiency, and compliance during aircraft maintenance operations.
