Tronair 02A7922C0100 – 12-Ton Tripod Jack, Air Pump

The factory-installed pneumatic pump helps technicians raise the aircraft jack more quickly while reducing operator fatigue during repetitive lifting procedures. Tronair specifies that the hydraulic pump operates with a recommended air supply of 90 to 100 PSI, allowing efficient extension of the ram during aircraft servicing operations. The pneumatic system can improve workflow efficiency in busy MRO and airline maintenance environments where minimizing downtime is critical. Its integrated design also eliminates the need for separate external lifting equipment.

The tripod configuration distributes load forces across three support points to help improve balance and lifting stability. Adjustable floor pads and an integrated bubble level further assist technicians in properly leveling the jack before lifting begins. Maintaining a level lifting position is especially important when servicing large commercial aircraft, such as the Airbus A220 and Bombardier CS100/CS300. Tronair also recommends raising and lowering all aircraft jacks simultaneously to help keep the aircraft level throughout maintenance procedures.

The hold-to-run air valve requires the operator to actively hold the control lever while the pneumatic pump is raising the ram. If the operator releases the valve, upward movement immediately stops, helping reduce the risk of unintended jack movement. This added layer of operational control can improve safety during aircraft jacking procedures in busy maintenance environments.

The built-in bubble level helps technicians verify that the aircraft tripod jack is properly aligned before and during lifting operations. Proper leveling helps maintain load stability and reduces uneven force distribution on the aircraft jacking point. The bubble level should be checked for accuracy every six months. This feature supports safer and more precise aircraft maintenance procedures.

The Tronair 02A7922C0100 is built with heavy-duty welded structural components, corrosion-resistant finishes, and serviceable hydraulic systems, making it suitable for long-term use. The manual outlines preventative maintenance procedures, such as periodic lubrication, hydraulic fluid replacement, and annual load testing, to help maximize service life. Tronair also recommends exercising the ram every 90 days during low-use periods to help protect seals and internal cylinder surfaces from corrosion buildup. These maintenance-friendly features help extend operational reliability in demanding hangar conditions.

OEM approval helps confirm that the aircraft tripod jack meets the lifting and support requirements specified for certain aircraft models. The Tronair 02A7922C0100 is specifically approved for the Bombardier CS100, CS300, Airbus A220-100, and A220-300 platforms. This approval provides additional confidence that the jack is suitable for these aircraft maintenance applications when used in accordance with the aircraft maintenance manual. Using OEM-approved ground support equipment can also help support regulatory compliance and maintenance standardization.

The jack includes heavy-duty wheels and an integrated towbar system to simplify movement within maintenance facilities. Tronair also provides wheel lock mechanisms that help stabilize the unit during towing operations. According to the manual, the jack can be towed at speeds up to 5 mph when properly configured. These mobility features help technicians reposition the 850-pound tripod jack more efficiently around large aircraft.

Annual load testing helps verify that the aircraft jack continues to operate safely within its rated lifting capacity. Tronair recommends testing the jack at 105% to 110% of its rated capacity to confirm proper hydraulic and structural performance. Routine testing can help identify worn seals, leaks, or pressure issues before they affect maintenance operations. This preventative maintenance practice supports safer aircraft lifting and long-term equipment reliability.

The hydraulic system incorporates multiple safety features designed to help prevent overloads and unintended lowering. These include a pressure relief valve, a ram locknut, a check valve system, and a locknut retention ring. The manual also emphasizes keeping the ram locknut within 1” of the ram during lifting or lowering procedures to provide maximum protection in the event of hydraulic failure. Together, these systems help improve safety during aircraft maintenance and inspection operations.

Tronair recommends storing the jack with the ram fully lowered and protecting the unit with a waterproof tarp or canvas cover when stored outdoors. The jack is designed to operate and be stored in temperatures ranging from -4°F to 122°F, making it suitable for various maintenance environments. Proper storage practices help minimize corrosion, preserve hydraulic seals, and maintain reliable lifting performance over time. Routine cleaning and avoiding direct water spray at the ram seal can also help extend service life.
