Tronair 02A7949C0100 – 15-Ton Tripod Jack

The Tronair 02A7949C0100 tripod jack is designed with multiple mobility features to simplify movement on the hangar floor. Its integrated tow handle and large rear wheels allow a single technician to maneuver the jack without the need for heavy equipment. The front swivel caster improves directional control, especially in tight workspaces. These features enable quick, safe, and efficient repositioning of the jack during aircraft maintenance.

A 15-ton capacity makes this jack suitable for a wide range of business jets, turboprops, and select regional aircraft. The load range supports lifting operations for aircraft with moderate gross weights that do not require heavy-duty 40-ton or 50-ton units. Maintenance shops often use this jack for landing gear work, brake service, tire changes, and routine gear inspections. Always confirm compatibility with your aircraft’s AMM before use.

The jack is engineered with a reinforced tripod structure that evenly distributes weight across three legs, reducing stress concentration and enhancing stability. Its wide stance helps minimize the risk of tipping when raising or lowering aircraft. The jack pad interface and optional extensions help ensure proper contact with OEM-approved jack points. This balanced design is essential for safe maintenance operations.

Yes, Tronair offers extensions designed to increase the effective height of the jack, allowing it to meet various aircraft jacking points. These accessories are commonly required when servicing aircraft with higher ground clearance or those that have unique maintenance procedures. Compatibility depends on the aircraft model and AMM requirements. Using OEM-approved extensions ensures safe and compliant lifting.

The mechanical lock nut provides a redundant safety layer by supporting the aircraft even if hydraulic pressure is lost. Technicians manually engage the lock by threading it down to the cylinder housing after lifting the aircraft. This prevents unintended lowering during extended maintenance operations. The lock design adheres to standard aviation safety practices commonly found in tripod jacks of this class.

Routine maintenance includes inspecting hydraulic seals, checking for fluid leaks, examining wheels and casters, and verifying the condition of the ram and lock nut threads. Lubrication points should be serviced according to Tronair’s recommended schedule. Regular cleaning also helps prevent corrosion or debris buildup around moving parts. Annual inspections are recommended to match typical hangar safety programs.

Yes, the jack is designed for one-person operation under standard maintenance conditions. Features like the tow handle, rear wheels, and smooth hydraulic pump help simplify the lifting process. However, aircraft jacking should always be performed with proper supervision and in accordance with OEM procedures. For major lifting tasks, many maintenance teams prefer two-person verification for safety.

Tronair generally specifies compatible aviation-grade hydraulic fluids that meet industry standards for tripod jacks, such as MIL-PRF-5606 or equivalent. Using the correct fluid ensures smooth jack operation, consistent pump performance, and proper seal compatibility. Always consult the Tronair service manual or decal on the jack for the exact fluid recommendation. Incorrect fluids may reduce service life or cause system damage.

The 02A7949C0100 is designed to operate reliably over a wide range of temperatures; however, hydraulic viscosity increases in cold conditions can impact pump performance. Using approved low-temperature hydraulic fluids helps maintain smooth operation during winter servicing. Technicians may need to manually cycle the pump to warm the fluid before lifting. Proper storage also helps preserve performance in harsh climates.

Technicians should always confirm jack point alignment, ensure the jack is on a level surface, and verify that chocks and restraints are in place. The mechanical lock must be engaged after lifting, especially for prolonged work. Personnel should avoid standing under or near gear doors or suspended loads during lifting operations. Following the aircraft AMM and Tronair manual is critical for safe use.

Many tripod jacks, including this model, feature built-in leveling indicators or bubble vials to assist with setup. The adjustable legs allow fine-tuning to achieve a stable platform. Proper leveling reduces side-loading on the ram and ensures smooth vertical travel. This step is essential when working on uneven hangar floors.

Lift time depends on the aircraft's weight, the required extension height, and the technician’s pump speed. For most mid-size business jets, the lifting process takes only a few minutes once the jack is positioned correctly. High-capacity hydraulic cylinders help reduce pumping effort while maintaining precision and accuracy. Safety checks typically take longer than the lifting motion itself.

Most operators include tripod jacks in their yearly ground support equipment inspections. Many MROs and fleet operators require formal load testing or functional checks per their internal safety programs. Tronair recommends periodic recertification to ensure the hydraulic system, structural components, and safety lock are all functioning correctly. This helps maintain compliance and avoid operational downtime.

The jack should be stored indoors in a clean, dry location to prevent corrosion and protect hydraulic components. Retracting the ram fully reduces exposure to contaminants and moisture. Many hangars store the jack on protective mats or designated GSE areas to avoid tire flat-spotting. Proper storage extends service life and maintains readiness for daily use.

Yes, the jack can be used on different jacking points as long as the aircraft’s AMM specifies tripod jack support for that location. Main gear lifting is more common, but many operators use 15-ton jacks at nose gear points on compatible aircraft. The ability to use the same jack across multiple points simplifies hangar operations. Always verify jacking procedures for each aircraft model.
