Tronair 02-7800C0110 – 12-Ton Tripod Jack

A tripod aircraft jack design helps distribute load forces evenly for improved stability during lifting operations. The wide tripod stance helps reduce movement during inspections, tire servicing, or landing gear maintenance. This configuration is especially valuable when lifting larger aircraft sections from the fuselage or wing jacking points.

The quick-rising center extension allows technicians to position the jack closer to the aircraft jacking point before hydraulic lifting begins. This reduces the hydraulic travel required and speeds up aircraft lifting procedures. The design also minimizes unnecessary pump strokes, thereby improving operator efficiency during repetitive maintenance tasks.

The ram locknut serves as a critical mechanical safety device that helps prevent unintended lowering while the aircraft is elevated. Tronair specifically instructs operators to lower the locknut as the aircraft is being raised to maintain proper load support. This added mechanical safeguard helps improve technician safety during maintenance operations performed beneath or around the aircraft.

The ram protection ring helps protect the jack’s mechanical extension and locking pin assembly from improper loading or deformation. Tronair’s manual emphasizes correct locking pin placement to ensure the protection ring functions properly during lifting operations. Proper use of the ram protection ring can help extend equipment life and reduce the risk of unsafe lifting conditions.

Heavy-duty casters make it easier to position and transport the 370-lb tripod jack throughout the hangar or maintenance facility. Improved mobility helps reduce setup time and allows technicians to maneuver the jack more efficiently around aircraft. The rolling design also simplifies repositioning during coordinated multi-jack lifting operations.

Tronair instructs operators to raise and lower all aircraft jacks simultaneously to help maintain proper aircraft balance and stability. Uneven lifting can place additional stress on the airframe or landing gear structure during maintenance. Coordinated lifting procedures help protect the aircraft while improving overall safety for maintenance personnel.

The single-stage hydraulic cylinder design delivers smooth, controlled lifting performance while reducing system complexity. Fewer moving hydraulic stages can help simplify maintenance and minimize potential leak points within the lifting system. The design also contributes to reliable operation during routine aircraft servicing and inspection procedures.

The built-in velocity fuse helps prevent a sudden ram descent in the event of a hydraulic line failure. This safety feature helps maintain aircraft support until repairs can be made and the system is safely reset. Added hydraulic protection is especially important during extended maintenance procedures where technicians may be working beneath the aircraft.

Annual load testing helps verify that the tripod jack continues operating within its rated lifting capacity and safety tolerances. Tronair recommends testing the jack at 105% to 110% of rated capacity to confirm structural and hydraulic integrity. Regular testing and inspection help maintenance facilities maintain compliance with aviation safety standards and reduce the risk of equipment failure.

The 02-7800C0110 is engineered specifically for aircraft lifting applications and is designed to operate across a wide temperature range from -4°F to 122°F. Its durable steel construction, powder-coat finish, and aviation-approved hydraulic components help support long-term use in demanding hangar and flight line environments. OEM approval for the BAe ATP further demonstrates the jack’s compatibility with professional aircraft maintenance operations.
