Tronair 02A7859C0100 – 12-Ton Tripod Jack, Air Pump

The Tronair 02A7859C0100 aircraft tripod jack is designed for heavy-duty lifting operations involving commercial, regional, and business aircraft. Its 12-ton lifting capacity allows technicians to safely support aircraft during landing gear service, tire changes, brake work, and structural inspections. The welded tripod frame and high-strength hydraulic system help provide stability during elevated maintenance procedures. The unit’s rugged construction also supports long-term use in busy hangar and flight line environments.

The two-stage hydraulic ram design allows the aircraft jack to achieve substantial lifting height while maintaining controlled operation throughout the lift cycle. This configuration helps technicians position the jack more precisely beneath varying aircraft jacking points. The staged extension also supports smoother lifting during maintenance procedures that require gradual aircraft elevation. According to the Tronair service manual, the jack includes both hydraulic and mechanical extension capability for improved versatility.

The ram protection ring helps prevent deformation and improper pin placement in the locking pin area during lifting operations. The operation manual emphasizes that proper installation of the locking pin is critical for maintaining safe load support while the aircraft is elevated. Proper use of the ram protection ring helps reduce the risk of premature equipment wear or unsafe lifting conditions. This added protection supports safer maintenance practices and longer jack service life.

The factory-installed air pump enables technicians to achieve rapid ram extension with standard shop air, reducing the manual pumping required during setup. Faster extension can help maintenance teams reduce aircraft downtime and improve workflow efficiency in high-volume hangar operations. The pneumatic assist feature is especially useful when positioning multiple jacks during aircraft leveling procedures. The integrated air system also helps reduce operator fatigue during repetitive lifting tasks.

Routine maintenance plays an important role in preserving aircraft jack performance and reliability. 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 advises protecting exposed ram surfaces with approved water-repellent lubricants during extended storage periods. Following these maintenance guidelines can help reduce wear and extend operational lifespan.

Aircraft manufacturers and ground support equipment providers recommend raising and lowering all jacks simultaneously to help maintain proper aircraft balance. Uneven lifting can place additional stress on the airframe and create unsafe maintenance conditions. The Tronair manual specifically instructs technicians to keep the aircraft level throughout lifting operations. Using coordinated lifting procedures helps improve stability and supports safer maintenance practices.

The threaded ram locknuts provide a mechanical backup to the hydraulic lifting system by helping prevent unintended ram lowering while the aircraft is elevated. Technicians are instructed to lower the locknuts as the aircraft is raised so the jack remains mechanically secured during maintenance. This additional safety layer is especially important during extended inspections or repairs performed beneath the aircraft. Mechanical locking systems are widely recognized as a critical safety feature in aviation jacking equipment.

Tronair recommends storing the aircraft tripod jack with the ram fully retracted to help protect internal hydraulic components and exposed surfaces. The manual also states that the jack may be stored outdoors if covered with a waterproof tarp or canvas. Keeping the equipment clean and protected from moisture helps reduce corrosion and hydraulic contamination. Proper storage practices can help preserve lifting performance and reduce maintenance requirements over time.

MIL-PRF-5606 hydraulic fluid is widely used in aviation maintenance equipment because it offers dependable performance across a broad operating temperature range. The fluid supports smooth hydraulic response in both cold-weather and high-temperature maintenance conditions. Aviation-approved hydraulic fluids also help protect seals, valves, and internal hydraulic components from premature wear. Using the specified fluid helps maintain consistent jack operation and supports long-term reliability.

The CE marking confirms that the Tronair 02A7859C0100 meets the applicable European machinery safety requirements. According to the declaration of conformity included in the manual, the jack complies with the European Machinery Directive and related safety standards. This certification can help international airlines, MRO providers, and maintenance facilities meet regulatory and workplace-safety requirements. CE-certified equipment is often preferred for global aviation support operations.
