Tronair 02A7822C0110 – 5-Ton Tripod Jack, Air Pump

The Tronair 02A7822C0110 is OEM-approved for ATR 42 and ATR 72 aircraft, making it a trusted solution for regional airline maintenance operations. Its 10,000-lb lifting capacity and two-stage hydraulic design provide the controlled lifting performance required for fuselage and wing jacking procedures. The jack’s compact footprint and 70” maximum height also help technicians work efficiently in crowded hangars and maintenance facilities.

The two-stage hydraulic configuration enables the jack to reach a higher lifting height while maintaining stability and controlled operation. The jack includes a 9” mechanical extension and 34” of hydraulic extension for added versatility during aircraft maintenance. This design helps technicians adapt to varying aircraft jack point heights without sacrificing lifting precision. It also supports smoother stage progression during raising and lowering operations.

The ram protection ring helps ensure the locking pin is installed correctly during aircraft lifting procedures. Tronair warns that incorrect pin placement can damage the jack and potentially lead to failure below certified load ratings. The manual also specifies that damaged or deformed protection rings should never be used. This safety feature helps maintenance personnel reduce the risk of improper setup during critical aircraft jacking operations.

Aircraft manufacturers generally require all tripod jacks to be raised and lowered simultaneously to maintain proper aircraft balance. Uneven lifting can place unnecessary stress on the airframe and create unsafe maintenance conditions. Tronair specifically instructs operators to keep the aircraft level throughout jacking operations and to use tail or nose stands when applicable for added stability. Following these procedures helps improve technician safety and protect the aircraft structure.

Routine inspections, hydraulic fluid checks, and periodic seal cycling all help maximize jack reliability and service life. Tronair recommends fully extending and retracting the jack every 90 days during low-use periods to exercise seals and help prevent internal corrosion. The manual also advises annual capacity testing at 105% to 110% of rated load to verify performance. Consistent preventative maintenance can help reduce downtime and improve long-term operational safety.

The factory-installed air pump allows technicians to quickly raise the jack during initial lifting without relying solely on manual pumping. This can reduce operator fatigue and speed up aircraft positioning during inspections, tire changes, and landing gear maintenance. The pneumatic-assisted system is especially beneficial in high-cycle maintenance environments where repeated jacking procedures are common. Tronair’s hydraulic schematic also shows how the air-driven and manual hydraulic systems work together for controlled lifting performance.

The hold-to-run air valve requires continuous operator engagement during air-powered lifting operations. Releasing the valve immediately stops upward ram movement, helping operators maintain better control throughout the jacking process. This feature helps reduce the likelihood of unintended lifting or uncontrolled movement during aircraft maintenance. It also supports compliance with modern aviation ground support equipment safety practices.

MIL-PRF-5606 hydraulic fluid is widely used in aviation ground support equipment because it performs reliably across broad temperature ranges and helps protect hydraulic system components. The fluid supports smooth ram operation while helping minimize wear on seals, pumps, and cylinders. Tronair also references compatible maintenance and handling procedures for aviation-approved hydraulic fluids throughout the manual. Using the proper hydraulic fluid helps maintain lifting performance and long-term reliability.

Tronair specifically states that only OEM replacement parts should be used with the 02A7822C0110 jack. Using non-approved parts or unauthorized modifications can void warranties and potentially compromise lifting safety or certified load capacity. OEM components are engineered to match the original hydraulic, structural, and safety specifications of the jack. This helps maintenance facilities maintain compliance with aviation industry best practices and equipment standards.

The tripod design helps evenly distribute load forces across the jack structure, improving stability during aircraft lifting. Combined with heavy-duty caster wheels and a reinforced steel frame, the design helps technicians position the jack more accurately beneath aircraft jacking points. Stable positioning is especially important during maintenance procedures involving landing gear, brakes, or tire servicing. The wide tripod base also helps reduce the risk of shifting during lifting operations.
