Tronair 02C7856C0100 – 5-Ton Tripod Jack, Air Pump

The Tronair 02C7856C0100 5-ton tripod jack is designed for aircraft maintenance tasks, including landing gear servicing, wheel and brake changes, tire replacement, and structural inspections. Its 10,000-lb lifting capacity makes it well-suited for turboprops, light business jets, and military aircraft applications. The jack is commonly used in hangars, MRO facilities, and line maintenance operations where stable aircraft lifting is required. Tronair specifically approves the jack for aircraft, including the Cessna Caravan, King Air, Challenger 300/350, and Gulfstream G150.

The factory-installed pneumatic pump helps technicians achieve faster initial ram extension compared to manual pumping alone. This can reduce setup time during repetitive maintenance procedures and improve productivity in busy aviation maintenance environments. The system operates with shop air between 25 PSI and 125 PSI, with 40 PSI recommended for optimal performance. Operators can also continue using the manual hand pump when compressed air is unavailable.

The hold-to-run air valve requires continuous operator engagement for the ram to rise using pneumatic power. Releasing the valve immediately stops upward movement, helping technicians maintain better control during aircraft lifting procedures. This feature adds an extra layer of operational safety by reducing the chance of unintended ram movement.

The ram protection ring helps ensure proper placement of the locking pin during mechanical extension setup. Correct placement protects the structural integrity of the ram assembly and reduces the risk of premature component damage or unsafe lifting conditions. Tronair provides detailed visual guidance showing acceptable and unacceptable locking pin positions to help technicians avoid deformation or failure. The manual also states that damaged protection rings or locking pins should never be used.

The tripod configuration distributes weight evenly and helps maintain stable support while lifting aircraft from the fuselage or wing jacking points. This design can help reduce movement during maintenance procedures that require precise aircraft positioning. Tronair also recommends raising and lowering all aircraft jacks simultaneously to keep the aircraft level throughout the operation. For additional stability, the manual advises using a nose or tail stand whenever applicable.

The Tronair 02C7856C0100 is designed to operate from -4°F to 122°F (-20°C to 50°C), enabling it to perform in a variety of hangar and ramp conditions. This broad operating range helps maintenance crews support aircraft operations in both cold-weather and hot-weather environments. Consistent hydraulic performance across different climates is especially valuable for operators supporting regional fleets or military aircraft deployments. Proper environmental compatibility also helps improve long-term equipment reliability.

The jack’s 12" mechanical extension allows technicians to quickly position the ram close to the aircraft jacking point before hydraulic lifting begins. This reduces the amount of hydraulic travel required and speeds up the lifting process. Combined with the 22" hydraulic extension, the jack achieves a maximum lifting height of 64”. The quicker setup can help reduce technician workload during routine maintenance operations.

Routine inspection and preventative maintenance are essential for keeping the aircraft jack operating safely and efficiently. Tronair recommends checking hydraulic fluid levels before each use, lubricating casters every three months, and performing annual load testing at 105% to 110% of rated capacity. The manual also advises storing the jack with the ram fully lowered and protecting exposed surfaces during extended storage periods. Following the manufacturer’s maintenance schedule can help reduce wear and prolong service life.

OEM approval confirms that the aircraft jack meets the aircraft manufacturer's lifting and compatibility requirements. Using an approved tripod jack can help maintenance facilities comply with aircraft servicing procedures and industry safety standards. It also helps ensure proper jack geometry, lifting capacity, and jack pad compatibility for supported aircraft models. This is especially important when servicing aircraft such as the Cessna Caravan, King Air, Falcon 10, or Challenger 350.

The jack is equipped with spring-loaded casters that allow technicians to move it efficiently throughout maintenance facilities and flight lines. According to the service manual, the unit weighs approximately 105 lbs, balancing portability with structural durability. Tronair also notes that the jack can be transported by crane or forklift when required for larger maintenance operations. These mobility features help support flexible aircraft servicing workflows in both hangar and field environments.
