Tronair 02A7917C0100 – 15-Ton Tripod Jack

The three-stage hydraulic configuration allows the Tronair 02A7917C0100 to achieve a maximum lifting height of 59” while maintaining a relatively compact 20” closed height. This extended range makes the jack suitable for a variety of aircraft maintenance tasks involving fuselage and wing jacking points. The staged extension system is designed so that each hydraulic ram extends sequentially from the largest to the smallest diameter, helping improve lifting stability and control during operation.

OEM approval helps confirm that the 02A7917C0100 meets the lifting and support requirements established for the Gulfstream G280. This can provide added confidence for maintenance teams performing inspections, servicing, or landing gear work on this aircraft platform. Using an OEM-approved aircraft tripod jack may also support compliance with approved maintenance procedures and reduce compatibility concerns. Always follow the aircraft maintenance manual for proper jacking locations and procedures.

The built-in mechanical extension allows technicians to quickly adjust the jack height before engaging the hydraulic lifting stages. According to the operation manual, the mechanical extension provides up to 4” of travel to help position the jack more efficiently beneath aircraft jacking points. This feature can reduce hydraulic cycling during setup and improve overall lifting efficiency. Faster positioning is especially useful during routine inspections and scheduled maintenance operations.

The CE hand pump with an integrated check valve helps prevent unintended aircraft descent if the relief valve fails during operation. This added hydraulic protection supports safer aircraft lifting and maintenance procedures by maintaining controlled pressure within the system. Combined with the ram locknut system, the check valve provides multiple layers of lifting security. The manual specifically identifies this feature as part of the jack’s functional safety system.

Aircraft tripod jacks should always be raised and lowered simultaneously to help keep the aircraft level throughout maintenance operations. Uneven lifting can place unnecessary stress on the fuselage, landing gear, or wing structure. Tronair specifically instructs operators to coordinate all jacks together during lifting and lowering procedures. This practice is particularly important when performing structural inspections, tire changes, or landing gear maintenance.

The ram locknut serves as a mechanical safety support that helps prevent unintended lowering of the aircraft during maintenance procedures. Operators are instructed to keep the locknut within 1” of the extending ram while lifting to maintain proper support. This feature helps protect technicians in the event of hydraulic pressure loss or line failure. Tronair emphasizes throughout the manual that proper use of the ram locknut is critical for safe aircraft jacking operations.

Routine maintenance includes checking hydraulic fluid levels before each use, lubricating wheels every three months, and performing annual capacity testing at 105% to 110% of rated capacity. Tronair also recommends fully extending and retracting the jack every 90 days during low-use periods to help protect seals and prevent internal corrosion. Keeping ram threads clean and using approved water-repellent protectants can further improve long-term performance. Proper preventative maintenance helps ensure reliable lifting capability and extended service life.

MIL-PRF-5606 hydraulic fluid is commonly used in aviation maintenance equipment because it provides dependable performance across a broad operating temperature range. The fluid helps support seal compatibility, corrosion resistance, and smooth hydraulic operation in demanding maintenance environments. Tronair specifies this aviation-grade fluid for both the jack and compatible hand pump systems. Using the correct hydraulic fluid can help reduce premature wear and maintain lifting reliability.

The tripod configuration helps evenly distribute lifting forces while providing a stable support platform on level hangar surfaces. Heavy-duty wheels and integrated handling features also make it easier for technicians to reposition the jack around the aircraft during maintenance operations. According to the manual, the jack can be rolled by hand on its wheels or transported by crane or forklift when needed. This mobility improves efficiency in busy aviation maintenance environments.

Tronair recommends storing the jack with the ram fully retracted to help protect internal hydraulic components and seals. The manual also states that the jack is suitable for outdoor storage when covered with a waterproof tarp or canvas. Proper storage practices help minimize moisture exposure, corrosion, and contamination that could affect lifting performance. Regular inspection during storage periods can also help identify wear or hydraulic issues before the next use.
