Tronair 02A7828C0110 – 5-Ton Tripod Jack, Air Pump

The Tronair 02A7828C0110 is OEM-approved for aircraft, including the Dornier DO328, Dornier DO328 Jet, Envoy 3, and Gulfstream G280, making it a versatile aircraft tripod jack for regional airline and corporate aviation maintenance operations. Its 10,000-lb lifting capacity supports a wide range of maintenance tasks involving fuselage and wing jacking points. Because it is specifically approved for these aircraft platforms, maintenance technicians can use it with confidence during inspections, tire changes, and landing gear servicing. OEM-approved ground support equipment also helps operators maintain compliance with manufacturer-recommended maintenance procedures.

The 02A7828C0110 features a minimum closed height of 21.75”, which can simplify positioning beneath lower aircraft jacking points. This lower profile is especially helpful when working with aircraft that have reduced ground clearance or limited hangar space. Easier positioning can reduce setup time and improve technician maintenance efficiency. The compact starting height also contributes to smoother jack alignment during aircraft lifting operations.

The integrated air-driven hydraulic pump helps accelerate the lifting process by reducing the amount of manual pumping required during initial extension. This can help technicians complete aircraft lifting procedures more efficiently in busy maintenance environments. The hydraulic schematic in the manual also shows how the pneumatic and hand pump systems work together to provide controlled lifting performance. Reduced manual effort can help minimize operator fatigue during repetitive maintenance tasks.

Tronair places significant emphasis on proper locking pin installation, as improper placement can lead to premature jack failure under load. The manual specifically warns against positioning the locking pin washer or ball lock inside the ram protection ring groove. Correct pin placement helps maintain structural integrity while supporting the aircraft during maintenance operations. The detailed diagrams included in the service manual help technicians verify safe installation procedures before lifting begins.

The ram protection ring helps secure the mechanical extension locking system and provides a visual reference for correct pin installation. Tronair instructs operators never to use the jack if the ram protection ring is damaged, deformed, or missing. Maintaining this component in proper condition helps prevent improper staging and unsafe lifting. This added safety feature supports safer aircraft maintenance operations in hangars and on ramps.

Tronair recommends regular preventive maintenance to keep the aircraft jack operating safely and efficiently. Suggested procedures include checking hydraulic fluid levels before each use, lubricating casters every three months, and performing annual load testing at 105% to 110% of rated capacity. For jacks stored or used infrequently, the manufacturer recommends fully extending and retracting the ram every 90 days to help protect seals and prevent internal corrosion. Following these maintenance practices can help reduce downtime and extend equipment service life.

The service manual instructs operators to raise and lower all aircraft jacks simultaneously to keep the aircraft level throughout the maintenance procedure. Uneven lifting can place unnecessary stress on the aircraft structure, landing gear, or jacking points. Tronair also recommends using a tail or nose stand for additional stability when applicable. Proper lifting procedures help improve technician safety while protecting the aircraft from potential damage.

The hold-to-run air valve requires the technician to actively hold the control lever during pneumatic lifting operations. Releasing the lever immediately stops upward ram movement, helping improve operational control during aircraft lifting. This safety feature helps reduce the risk of unintended jack movement during aircraft positioning or raising. Improved control is especially valuable when performing precision maintenance operations around sensitive aircraft structures.

MIL-PRF-5606 hydraulic fluid is widely used in aviation ground support equipment because it provides reliable hydraulic performance across a broad temperature range. The fluid helps protect seals, cylinders, and internal hydraulic components while supporting smooth lifting operation. Tronair also specifies proper fluid-handling, storage, and disposal procedures in the maintenance manual. Using approved aviation hydraulic fluid helps preserve long-term jack reliability and lifting consistency.

The Tronair 02A7828C0110 is CE marked and complies with several European machinery and aircraft ground support equipment safety standards. According to the declaration of conformity, the jack meets requirements related to stability, strength, risk reduction, and aircraft jack safety performance. CE compliance can provide added confidence for operators working in international aviation maintenance environments. It also demonstrates that the equipment has been evaluated against recognized industry safety standards.
