Tronair 53D22020 – Columbus Jack 5-Ton Axle Jack

This model is completely self-contained, featuring an integrated manual hand pump and hydraulic reservoir that allow it to function independently of power sources. Weighing approximately 26 lbs (12 kg), the jack is lightweight enough for one-person transport while maintaining a robust steel base for stability. These characteristics make it particularly useful for military or commercial operators who need dependable ground support in remote or variable environments.

While compact, the Columbus Jack 53D22020 features a multi-stage ram assembly mounted inside a durable cylinder. This design ensures smooth lifting with reduced side loading, enhancing operator safety and preventing uneven pressure distribution during aircraft jacking. As a result, it provides longer component life and more reliable operation over repeated maintenance cycles.

The Columbus Jack 53D22020 is compatible with a wide range of light to medium aircraft, depending on their jacking point requirements and load distribution. Its 5-ton capacity and adjustable extension screw make it suitable for multiple aircraft types used in general aviation, business aviation, and certain military applications. This versatility allows maintenance teams to rely on a single unit for numerous models.

The unit features a relief valve, an adjustable cover to prevent overloading, and a hydraulic fuse that safeguards against sudden pressure loss in the event of hose or seal failure. It also features a heavy square base for improved stability during lifting operations. Together, these components enhance operator safety and reduce the risk of damage to equipment or aircraft during maintenance.

A #50 mesh filter (297-micron) is integrated into the design to prevent contaminants from entering the hydraulic system. This filtration feature helps maintain smooth operation, reduce seal wear, and extend service intervals. Keeping the hydraulic fluid clean ensures long-term reliability, particularly when the jack is used frequently or stored in variable environments.

The reservoir air vent and fill port drain make fluid maintenance and system bleeding straightforward. These features allow technicians to easily top off or replace hydraulic fluid, minimizing downtime and ensuring consistent pressure during lifting operations. This is especially crucial in aviation maintenance environments, where precision and uptime are paramount.

Routine inspections of seals, fluid levels, and the relief valve should be performed according to the manufacturer's guidelines. Columbus Jack provides maintenance kits, including seal kits (SKTES3-6) and repair kits (TES3-6), to support easy field servicing. Following a consistent maintenance schedule ensures reliable operation and compliance with ground support safety standards.

Yes. Columbus Jack products, including the 53D22020, are built to meet stringent military and aviation requirements. The company’s 90-year history of supplying jacks to the U.S. Military and allied forces demonstrates compliance with strict quality, reliability, and performance specifications.

This model’s compact 11.5" × 3" × 7" frame and single carrying handle allow for quick positioning beneath landing gear axles. Its small footprint and lightweight design make it ideal for maintenance operations in tight hangar spaces or mobile maintenance units. Additionally, its self-contained hydraulic system eliminates the need for external hoses or power connections.

The 53D22020 operates at an internal system pressure of approximately 4,980 PSI, with a relief valve that opens between 5,229 and 5,478 PSI. This built-in protection ensures that the jack performs safely under heavy load conditions without overstressing internal components. The precision calibration of these valves helps maintain smooth, controlled lifting performance.
