Tronair 02-7933C0100 – 5-Ton Axle Jack

The Tronair 02-7933C0100 5-ton axle jack is designed to safely lift aircraft for maintenance, inspection, and servicing tasks. It is commonly used on aircraft such as the Pilatus PC-12 and Dornier 228-100/200. With a vertical lifting capacity of 10,000 lbs (44.48 kN), it provides reliable performance for axle-based lifting applications. This aircraft axle jack is ideal for technicians who require precision and stability during maintenance operations.

This aircraft axle jack features rugged steel construction for long-term durability in demanding environments. It includes a three-stage telescoping ram and a quick-action mechanical extension for efficient height adjustment. The single-speed, manually operated hydraulic pump ensures controlled lifting. A preset relief valve enhances safety by preventing overload conditions.

The Tronair 02-7933C0100 axle jack has a maximum vertical capacity of 10,000 lbs (44.48 kN), equivalent to 5 tons. This capacity makes it suitable for a wide range of aircraft maintenance applications. It is engineered to handle consistent lifting loads while maintaining stability and control. Always ensure the load does not exceed the rated capacity for safe operation.

This hydraulic axle jack has a minimum closed height of 5.63” (14.3 cm) and a maximum height of 17.5” (44.4 cm). It also features a mechanical extension of 2.63” (6.7 cm) and a hydraulic extension of 9.25” (23.5 cm). This wide height range allows for flexible positioning under various aircraft configurations. The multi-stage extension system helps improve efficiency during setup.

The Tronair 02-7933C0100 axle jack is designed to use MIL-PRF-5606 hydraulic fluid. This aviation-grade fluid ensures proper lubrication, consistent performance, and compatibility with internal seals and components. Using the recommended fluid helps extend the jack's life and maintain reliable operation. Always follow manufacturer guidelines when servicing the hydraulic system.

The three-stage telescoping ram allows for a greater lifting range while maintaining a compact design when fully collapsed. This feature improves efficiency by reducing the need for excessive manual adjustment. It also provides smoother and more controlled lifting throughout the extension process. This design is especially beneficial when working in tight maintenance spaces.

The Tronair 02-7933C0100 includes a preset relief valve to prevent overpressurization during operation. It also requires the reservoir vent screw to be opened before use to ensure proper hydraulic function. Safety guidelines emphasize using the jack on a hard, level surface and avoiding contact between hands and the aircraft jack point. These built-in and procedural safety measures help protect both technicians and equipment.

To operate the jack, position it on a stable, level surface and extend the mechanical screw until it meets the aircraft jack point. Open the reservoir vent screw, then close the pump release valve and begin pumping to raise the aircraft. For lowering, slowly loosen the release valve to allow a controlled descent. Following proper operating procedures ensures safe and efficient lifting.

Regular maintenance includes checking hydraulic fluid levels, inspecting seals, and ensuring all fasteners are secure. It is recommended to replace seals and wiper rings when removed to prevent leaks and maintain performance. The system should be flushed and refilled with clean hydraulic fluid during servicing. Annual load testing is also recommended to verify proper operation and safety.

Common issues include low hydraulic fluid levels, a closed vent screw, or an improperly tightened release valve. Internal component wear, such as damaged O-rings or valve issues, can also affect performance. If the jack fails to lift or hold a load, inspecting seals and check valves is recommended. Addressing these issues promptly helps maintain reliable operation and extend the equipment's life.
