Tronair 02A7913C0100 – 30-Ton Tripod Jack, Air Pump

The Tronair 02A7913C0100 tripod jack incorporates multiple integrated safety features, including user-operated ram locknuts, a pressure relief valve, and a hold-to-run air valve system. The ram locknuts act as a mechanical safeguard, preventing unintended descent if hydraulic pressure is lost. A check-valve-equipped hand pump further reduces the risk of accidental lowering. These layered protections help maintenance teams perform aircraft lifting operations with greater confidence and control.

The ram locknuts are manual safety devices that must be lowered as the aircraft is raised to mechanically secure the load. Failure to engage the locknuts can result in uncontrolled descent in the event of hydraulic failure. The manual specifically warns that neglecting proper locknut use may lead to serious injury or equipment damage. Keeping the locknut within one inch of the ram during operation ensures maximum protection.

For models equipped with the air pump, including the 02A7913C0100, the recommended air supply range is 90 to 145 PSI (6.21 to 10 bar). A full 145 PSI is required to reach the maximum extension height. Maintaining proper inlet pressure ensures smooth hydraulic staging and optimal lifting performance during aircraft maintenance procedures.

Before operation, technicians should inspect all fittings, verify hydraulic fluid levels via the sight glass, and cycle the ram fully at least three times without a load. The unit uses MIL-PRF-5606 hydraulic fluid, and maintaining the proper level is essential for safe operation. Pre-use checks help identify leaks, loose hardware, or performance irregularities before lifting an aircraft.

The 30-ton, two-stage jack is designed to operate within a temperature range of -4°F to 122°F (-20°C to 50°C). It should be used on a clean, level surface to maintain stability. Operating outside recommended conditions may affect hydraulic performance and overall safety during aircraft lifting procedures.

Routine maintenance includes checking hydraulic fluid levels before each use and lubricating casters every three months . An annual capacity test at 105% to 110% of rated load is recommended to verify structural integrity and lifting capability. Regular inspection and preventative maintenance extend the life of the aircraft jack and help ensure compliance with safety protocols.

The Tronair 02A7913C0100 is compatible with MIL-PRF-5606 hydraulic fluid. Using the specified fluid ensures proper lubrication, seal compatibility, and hydraulic performance. Substituting non-approved fluids can lead to seal degradation, internal damage, or loss of lifting capacity.

For storage, the ram should be fully retracted, and the release screw opened. The manual recommends storing the unit in a clean, dry environment and covering it if kept outdoors. Proper storage minimizes corrosion, protects seals, and ensures readiness for future aircraft maintenance operations.

Tronair warrants this aircraft tripod jack against manufacturing or material defects for one year from the date of shipment to the original customer. The warranty covers repair or replacement of defective components but excludes normal maintenance parts and unauthorized modifications. Using only Tronair OEM replacement parts preserves warranty coverage and operational reliability.
