Tronair 02-7839C0111 – 18-Ton Tripod Jack

A wide base radius improves stability when lifting large aircraft, especially at higher extension heights. This design helps distribute weight evenly across the tripod legs, reducing the risk of tipping or shifting during maintenance. The large footprint is particularly beneficial when working on wide-body or heavier aircraft structures. It allows technicians to perform lifting operations with greater confidence and control.

The ram locknut serves as a mechanical safety backup, physically preventing the ram from lowering under load. Operators are required to keep the locknut positioned close to the load as the aircraft is raised to maintain continuous support. This feature provides an added layer of protection in the event of a hydraulic failure. Proper use of the locknut is critical to safe aircraft jacking procedures.

The extended lifting range allows this tripod jack to service a wide variety of aircraft with higher ground clearance or tall fuselage structures. It is especially useful for heavy transport aircraft, military platforms, and large business jets. The ability to reach significant heights without compromising stability improves versatility in hangar operations. This flexibility allows maintenance teams to use a single jack across multiple aircraft types.

The hydraulic system uses a controlled pump and release valve setup to manage lifting and lowering operations. Fluid flow is regulated through check valves and a pressure relief valve to ensure consistent performance. This design helps prevent sudden movements and allows for precise control during positioning. Smooth operation is essential when working with sensitive aircraft structures.

When multiple jacks are used, they must be raised and lowered simultaneously to keep the aircraft level. Uneven lifting can place excessive stress on the airframe or lead to instability. The manual specifically instructs operators to coordinate movements across all jacks during operation. Maintaining balance is essential for safe and effective aircraft maintenance.

Routine maintenance includes checking hydraulic fluid levels, inspecting seals, and replacing worn components as needed. The maintenance schedule recommends regular inspections and annual load testing to verify performance. Keeping the hydraulic system clean and properly filled ensures consistent lifting capability. These practices help prevent downtime and extend equipment life.

Storing the jack in a controlled environment helps protect it from contamination, corrosion, and environmental damage. The manual recommends keeping the ram fully retracted and covering the unit when stored outdoors. Proper storage conditions help preserve seals, hydraulic components, and structural integrity. This ensures the jack is ready for reliable use when needed.

The tripod jack is designed to operate within a wide temperature range, making it suitable for various climates and maintenance environments. It must be used on clean, level surfaces to ensure stability and safe load handling. Additionally, the unit includes safety labels and operational guidelines to assist technicians during use. These features support consistent performance in both routine and demanding aviation maintenance scenarios.
