Tronair 02A7856C0100 – 5-Ton Tripod Jack, Air Pump

The Tronair 02A7856C0100 5-ton tripod jack is designed to support a broad range of regional, business, and utility aircraft maintenance operations. Its OEM-approved compatibility with aircraft such as the Cessna Caravan, Bombardier Challenger 300/350, and Citation 560 XL makes it a versatile solution for mixed-fleet operators. Maintenance facilities can use the same aircraft tripod jack across multiple platforms, helping streamline equipment management and reduce downtime. This flexibility is especially valuable for FBOs, MRO providers, and regional operators.

The integrated pneumatic air pump allows technicians to raise the jack more quickly during the initial lifting phase compared to manual pumping alone. This helps reduce operator fatigue and improves efficiency during repetitive maintenance tasks such as wheel changes, brake servicing, and landing gear inspections. The system operates with shop air pressures ranging from 25 PSI minimum to 125 PSI maximum, allowing compatibility with many standard maintenance facilities. Faster jack positioning can help improve aircraft turnaround times.

The hold-to-run air valve requires the technician to actively engage the control lever for upward ram movement, adding an extra layer of operational safety. Once the operator releases the valve, upward movement immediately stops, helping maintain controlled lifting conditions. This feature reduces the likelihood of unintended jack extension during aircraft maintenance procedures. Controlled operation is particularly important when working beneath elevated aircraft structures.

The jack is engineered for operation from -4°F to 122°F (-20°C to 50°C), ensuring reliable performance across a wide range of hangar and ramp conditions. Its durable powder-coated finish helps resist corrosion, exposure to hydraulic fluid, and everyday wear commonly found in aviation maintenance facilities. The heavy-duty tripod structure also helps provide stable lifting performance on approved level surfaces. These features contribute to long-term durability in commercial aviation environments.

The threaded ram locknut provides a mechanical load-holding feature that supplements the hydraulic lifting system. Once the aircraft is raised, technicians lower the locknut into position to help secure the load during maintenance operations. This mechanical support helps reduce reliance on hydraulic pressure alone while the aircraft is elevated. Proper use of the ram locknut is emphasized throughout Tronair’s operation and service manual.

Routine inspection and preventative maintenance are essential to the long-term performance of jacks. Tronair recommends checking hydraulic fluid levels before each use, lubricating casters every three months, and performing annual capacity testing at 105% to 110% of rated load capacity. The manual also recommends replacing worn O-rings, backup rings, and seals as needed to prevent hydraulic leakage and maintain lifting performance. Following the manufacturer’s maintenance schedule can help maximize equipment reliability.

The operation manual emphasizes proper installation of the locking pin within the ram protection ring groove to help maintain structural integrity during lifting operations. Incorrect pin placement can damage the ram protection ring or locking components, potentially compromising safe operation. Tronair also specifies that only one locking pin should be used in the designated location and that damaged pins or protection rings should never be reused. These procedures help ensure safe aircraft lifting practices.

The single-stage hydraulic design offers a straightforward lifting system with fewer moving hydraulic components than multi-stage jacks. This simplified design can facilitate servicing, reduce maintenance complexity, and ensure dependable lifting performance in approved aircraft applications. Combined with the mechanical extension, the jack still provides a substantial lifting range while maintaining stability. Single-stage systems are commonly used in aviation ground support equipment because of their durability and reliability.

The jack provides a maximum lifting height of 64", allowing technicians to reach elevated fuselage and wing jacking points on various aircraft types. This extended lifting range supports maintenance procedures involving landing gear servicing, tire replacement, and structural inspections. The combination of mechanical and hydraulic extension helps technicians position the jack accurately before full lifting begins. Proper lifting height capability is critical for safely supporting larger regional and business aircraft.

Even when a tripod jack is OEM-approved for certain aircraft models, technicians must still follow the aircraft manufacturer’s maintenance manual for proper jacking procedures, adapter selection, and load distribution requirements. Aircraft weight distribution, jacking point locations, and stabilization requirements can vary significantly between platforms. Tronair specifically advises operators to use the jack only in approved applications and to follow proper balancing procedures. Following approved aircraft maintenance practices helps protect both technicians and aircraft structures during lifting operations.
