02-7815-0100 - Tronair 02-7815C0110 – 10-Ton Tripod Jack

This 10-ton aircraft hydraulic tripod jack is commonly used for scheduled inspections, landing gear servicing, component replacements, and structural checks that require support for the fuselage or wings. It is designed for controlled lifting during line and hangar maintenance. The jack is intended to be used in conjunction with additional jacks to maintain proper aircraft balance. This makes it well-suited for coordinated multi-point jacking procedures.

A two-stage aircraft hydraulic jack utilizes multiple ram diameters to achieve a greater lifting height while maintaining stability. This design enables the jack to accommodate a wide range of aircraft geometries without compromising load control. The staged extension ensures smooth, predictable lifting during aircraft maintenance. It also helps reduce the overall footprint compared to taller single-stage designs.

Technicians should always use the jack on a level, hard surface and ensure proper alignment with the aircraft jack point. Ram locknuts must be engaged once the load is raised to prevent unintended movement. All jacks supporting an aircraft should be raised and lowered simultaneously to maintain balance. Proper personal protective equipment is also recommended during operation.

Ram locknuts serve as a mechanical safety device, supporting the load independently of hydraulic pressure. Once engaged, they reduce the risk of jack collapse due to pressure loss. Using the locknuts is a required safety step during aircraft lifting. Failure to engage them can result in serious injury or damage to the aircraft.

The locking pin must pass fully through the mechanical extension and seat in the groove of the ram protection ring, with the washer and ball lock positioned outside the ring. Incorrect placement – such as inserting the washer inside the groove – can deform or shear the pin, leading to structural failure. 

Routine visual inspections should be performed before each use to check for leaks, damage, or worn components. Tronair recommends periodic maintenance inspections – typically on a 90-day cycle – to inspect seals, condition the hydraulic system, and exercise the ram to prevent corrosion or seal degradation.

An annual functional load test is also recommended, typically conducted at 105% to 110% of the jack’s rated capacity, to verify safe load-holding performance. Even jacks used infrequently should be exercised and inspected regularly to maintain reliability, extend service life, and support compliance with maintenance best practices.

The jack is designed to use aviation-approved hydraulic fluid that meets MIL-PRF-5606 specifications. Maintaining proper fluid type and level is essential for reliable operation. Contaminated or incorrect fluid can damage seals and reduce lifting performance. Fluid levels should be checked with the ram fully retracted.

The jack should be operated in a clean, dry environment on a stable surface. Extreme temperatures, moisture, or debris can affect performance and component longevity. Protecting the jack during washing or cleaning operations is recommended. Controlled conditions help preserve seals and hydraulic components.

This aircraft hydraulic tripod jack is designed for use as part of a coordinated jacking system. A proper balance is achieved by positioning multiple jacks according to the Aircraft Maintenance Manual (AMM). The jack’s wide stance and controlled extension help maintain stability. Balanced lifting is essential for safe aircraft maintenance.

No. Modifications without written approval from Tronair are not permitted and will void the warranty. Only Tronair OEM replacement parts should be used during repairs. Using non-approved components can compromise safety and load capacity. OEM parts ensure the jack continues to meet its original design standards.

By providing controlled and stable lifting, the jack enables technicians to perform maintenance tasks safely on the ground. Integrated mechanical and hydraulic safeguards reduce reliance on pressure alone. Properly used aircraft jacks help prevent structural stress and accidental movement. This makes them a critical component of safe aircraft ground support operations.

For optimal longevity, the jack should be stored indoors or covered to protect it from exposure to moisture, Skydrol, or cleaning chemicals. Contaminants or liquids on the ram and cylinder can damage seals and O-rings over time. Always ensure the ram is fully retracted and the locknuts are lowered before storage.

Yes! PJi offers a wide range of replacement parts for Tronair GSE, including the 02-7815C0100 tripod jack. Using OEM parts helps maintain safety certifications and proper jack performance. 

Tronair offers a one-year limited warranty on all new ground support equipment (GSE) – including the 02-7815C0110 jack – covering defects in materials and workmanship. Replacement parts carry a standard 90-day warranty.

When the cost to repair a jack approaches or equals the cost of a new unit, replacement is the more economical choice. A heavily worn tripod jack requiring structural repairs, new seals, new fittings, paint, and load testing can approach the price of a new jack.
