Tronair 02-7855C0100 – 5-Ton Tripod Jack

The Tronair 02-7855C0100 aircraft tripod jack is designed to support a wide range of aviation maintenance procedures, including landing gear servicing, wheel and brake maintenance, aircraft weighing, structural inspections, and shock strut repairs. Its tall lifting range makes it especially useful for aircraft with higher fuselage or wing jacking points. Aircraft tripod jacks like this model are also commonly used during gear swing tests and scheduled heavy maintenance operations.

With a closed height of 84” and a maximum extended height of 116”, the Tronair 02-7855C0100 can accommodate aircraft with elevated wing and fuselage jacking locations. This added reach helps maintenance technicians safely access aircraft that require taller support equipment without relying on unstable extensions or improvised lifting methods. The broader height range also improves versatility across multiple aircraft platforms.

The mechanical ram locknut provides a positive locking mechanism that helps prevent unintended lowering of the aircraft while elevated. Unlike hydraulic pressure alone, the locknut creates a physical support point beneath the load during maintenance procedures. This added layer of protection is especially important when technicians are working beneath the aircraft or performing lengthy inspections. The operation manual specifically instructs operators to keep the ram locknut lowered during lifting operations for maximum safety.

The quick-rising center extension allows technicians to position the jack pad close to the aircraft jacking point before hydraulic lifting begins. This reduces the amount of pump travel required and speeds up overall jack setup time. Faster positioning can improve maintenance efficiency during routine inspections, tire changes, and line maintenance operations.

The Tronair 02-7855C0100 uses standard MIL-PRF-5606 hydraulic fluid, which is widely used throughout the aviation industry and readily available at many maintenance facilities. The simple single-speed hand pump design helps reduce system complexity while supporting dependable lifting performance. Routine maintenance procedures, including fluid checks and annual capacity testing, are straightforward and clearly outlined in the operation manual.

Annual load testing helps verify that the aircraft tripod jack can safely support its rated lifting capacity under operational conditions. Tronair recommends annual capacity testing at 105% to 110% of rated capacity to confirm safe performance and identify potential wear before failure occurs. Routine load testing also supports compliance with aviation maintenance quality and safety programs.

Proper storage and preventative maintenance are essential for extending the life of aircraft tripod jacks. Tronair recommends keeping the jack covered during washing operations and storing it away from moisture, Skydrol, and contaminants that could damage seals or hydraulic components. The manual also recommends fully extending and retracting the ram every 90 days if the jack is not used regularly to help prevent internal corrosion and seal deterioration.

CE certification indicates that the Tronair 02-7855C0100 complies with applicable European machinery safety and engineering standards. This certification helps operators standardize equipment across international maintenance operations while demonstrating compliance with recognized safety requirements. The included Declaration of Conformity references compliance with the Machinery Directive 2006/42/EC and EN ISO 12100 safety standards.
