Before use, technicians should inspect the jack for leaks, ensure the ram is fully retracted, and check that hydraulic fluid is at the proper level. Operators should also verify that all nuts, bolts, and fittings are secure and confirm the velocity fuse is intact. These checks reduce the risk of operational failure during lifting.

The ram locknut is a critical safety feature that prevents unintentional lowering of the load. Operators must lower the locknut against the ram as the aircraft is raised and ensure it remains seated while under load. Failure to use the ram locknut properly can lead to serious injury or damage.

Tronair recommends checking the fluid level before each use, lubricating casters every three months, and cleaning the jack annually or as needed. An annual capacity test at 105% to 110% of the rated load is also required to confirm safe performance. Preventative maintenance ensures compliance with aviation standards and prolongs service life.

When not in service, the tripod jack should be stored with the ram fully retracted and in a clean, dry environment between -4°F and 122°F (-20°C and 50°C). If left outdoors, it should be covered with a full-coverage waterproof tarp or canvas. These steps help protect hydraulic seals and prevent corrosion.

The jack can be rolled short distances on its casters for positioning within a hangar. For long-distance transport, it can be lifted by crane using straps through the tripod’s top or by a forklift under the lower tripod support. Proper strapping is required to prevent unwanted movement during shipment.

Seals and backup rings should be replaced whenever leakage occurs or during major service intervals. Tronair offers seal replacement kits such as K-1050 for ram seals and K-3441 for pump seals, ensuring technicians have the correct OEM components. Regular seal replacement helps maintain hydraulic integrity and prevents downtime.

The Tronair 12-ton tripod jack carries a one-year warranty against manufacturing and material defects, and replacement parts carry a 90-day warranty. Warranty coverage excludes normal wear items, misuse, or unauthorized modifications, so adhering to maintenance schedules and using OEM parts is essential for protection.
