Tronair 02A7839C0111 – 18-Ton Tripod Jack

The Tronair 02A7839C0111 is engineered specifically for high-capacity aircraft lifting applications, with a 36,000-lb lifting capacity designed to support aircraft such as the Bombardier Dash 8-400. Its heavy-duty tripod configuration provides the stability needed for maintenance procedures involving landing gear servicing, inspections, and structural work. OEM approval for the Dash 8-400 also helps maintenance teams align with approved aircraft jacking procedures and equipment requirements. This makes the jack a dependable solution for commercial and regional aviation maintenance operations. 

The single-stage hydraulic cylinder design helps provide controlled and stable lifting performance for large aircraft applications. With fewer moving hydraulic stages compared to multi-stage systems, single-stage jacks can simplify maintenance and reduce potential wear points over time. The design also allows the jack to achieve a maximum lifting height of 178.5” while maintaining structural rigidity during lifting operations. This combination of height capability and stability is valuable when servicing larger regional aircraft.

The 02A7839C0111 offers a minimum closed height of 120” and a maximum lifting height of 178.5”, providing technicians with a wide operating range for various aircraft maintenance procedures. This extended lift capability allows maintenance crews to safely access aircraft components that require significant ground clearance during servicing. The added height flexibility is especially useful during landing gear maintenance, tire replacement, and under-aircraft inspections. A broader lifting range also helps reduce the need for multiple specialized jack configurations.

The ram locknuts act as mechanical safety devices that help prevent unintended ram lowering during maintenance operations. Tronair instructs operators to keep the locknuts within two inches of the stop while raising the aircraft and to fully seat them once the aircraft is lifted. This added mechanical support helps protect technicians and aircraft structures in the event of hydraulic pressure loss. Mechanical locking systems are considered an important safety feature in professional aircraft tripod jacks.

The operation manual instructs technicians to raise and lower all aircraft jacks simultaneously to help maintain aircraft balance throughout the lifting process. Uneven lifting can place excessive stress on aircraft jacking points, landing gear structures, and surrounding airframe components. Tronair also recommends using a nose or tail stand when applicable for additional aircraft stability. Following proper synchronized lifting procedures helps improve both maintenance safety and equipment protection.

The built-in pressure relief valve helps prevent overload conditions during aircraft lifting operations by limiting hydraulic system pressure. This safety feature reduces the risk of excessive force being applied to the jack or aircraft jacking points during operation. Proper hydraulic pressure management also helps extend component life within the jack’s hydraulic system. Pressure relief systems are widely recognized as an important safeguard in aviation ground support equipment.

Tronair recommends routine preventive maintenance procedures, such as checking hydraulic fluid levels before each use, lubricating casters every 3 months, and performing annual capacity testing at 105% to 110% of the rated load. The manual also advises extending the ram every 90 days during long-term storage and applying a water-repellent lubricant to help protect seals and cylinder surfaces. Keeping the hydraulic system clean and properly serviced can help reduce downtime and maintain consistent lifting performance. Regular maintenance is especially important for heavy-capacity aircraft jacks used in demanding maintenance environments.

The 02A7839C0111 is rated for operation from -4°F to 122°F, making it suitable for a variety of hangar and ramp conditions. This wide operating range helps maintenance crews maintain productivity in both cold-weather and high-temperature environments. Consistent hydraulic performance across changing temperatures is critical for safe aircraft lifting operations. The broad environmental capability also supports year-round use in commercial aviation maintenance facilities.

The jack’s wide tripod footprint helps evenly distribute lifting loads during aircraft maintenance procedures. Combined with heavy-duty casters and reinforced leg weldments, the tripod structure is designed to provide stable positioning while supporting large aircraft loads. Stable lifting equipment is essential for minimizing movement and maintaining aircraft balance during maintenance operations. The robust tripod design also helps improve maneuverability when positioning the jack in busy hangar environments.

The Tronair 02A7839C0111 is CE marked and complies with European machinery safety requirements outlined under Directive 2006/42/EC. Compliance with internationally recognized safety standards helps reinforce the jack’s suitability for professional aviation maintenance environments. CE-marked aircraft jacks may also support operators working within international aviation facilities or multinational maintenance organizations. Meeting these standards demonstrates Tronair’s commitment to safety, quality, and regulatory compliance.
