Tronair 02A0517C0140 – 5-Ton Tripod Jack, Air Pump

The factory-installed air pump allows technicians to raise the jack more quickly during initial positioning, helping reduce manual pumping effort during aircraft maintenance procedures. This can improve workflow efficiency in busy hangars or flight line environments where fast aircraft turnaround is important. The integrated pneumatic system also eliminates the need for separate external lifting accessories. According to the Tronair operation and service manual, the air system operates with a recommended supply pressure of 40 PSI and a maximum of 125 PSI.

The two-stage hydraulic configuration provides extended lifting capability while maintaining stable and controlled aircraft support throughout the lift cycle. This design allows the jack to accommodate a wider range of aircraft jacking point heights compared to some single-stage models. The staged extension system also helps maintain smoother load distribution during lifting and lowering operations. Tronair’s service manual notes that the hydraulic rams extend in sequence from the largest to the smallest diameter stage for proper operation.

The hold-to-run air valve requires continuous operator engagement for pneumatic lifting, thereby maintaining direct control during aircraft jacking operations. If the operator releases the valve lever, upward ram movement immediately stops. This safety-focused design helps reduce the risk of unintended movement while positioning the aircraft jack under load. Tronair specifically identifies this feature as an operator-controlled safety mechanism within the manual.

The ram protection ring helps ensure proper placement of the locking pin used with the mechanical extension system. Correct pin positioning is critical for maintaining structural integrity and preventing premature component failure during lifting operations. The Tronair manual includes detailed illustrations showing both correct and incorrect pin placements to help technicians avoid unsafe configurations.

The quick-rising center extension allows technicians to bring the jack pad closer to the aircraft jacking point before engaging full hydraulic lifting pressure. This reduces the number of hand pump strokes required during initial setup and can improve maintenance efficiency. Faster positioning is especially useful during inspections, tire changes, and routine aircraft servicing, where multiple jacks may be used simultaneously.

The 5-ton load rating and versatile lifting design make this aircraft tripod jack suitable for a wide range of business jets, utility aircraft, helicopters, and military aircraft. OEM approvals for aircraft, including the Cessna Mustang 510, Eclipse 500, Bell helicopter models, and Airbus Military CASA aircraft, demonstrate its adaptability across multiple aviation sectors. This flexibility can help maintenance facilities standardize ground support equipment across mixed fleets.

The threaded handwheel-style safety nut provides positive mechanical support after the aircraft has been raised. Technicians can lower the safety nut against the ram during lifting operations to help secure the load independently of hydraulic pressure alone. This mechanical locking method is widely recognized throughout the aviation industry as an important aircraft jacking safety practice.

Routine fluid inspections, annual cleaning, caster lubrication, and scheduled load testing help maintain the long-term performance of aircraft jacks. Tronair recommends exercising the jack every 90 days during low-use periods to help protect seals and minimize internal corrosion buildup. The manual also advises using water-repellent protectants on exposed ram surfaces and threads when the jack is stored.

MIL-PRF-5606 hydraulic fluid is widely used throughout the aviation industry because it performs reliably across broad operating temperature ranges and is compatible with many aircraft hydraulic systems. Using aviation-approved hydraulic fluid helps support dependable lifting performance in both hangar and outdoor maintenance environments. Standardized fluid specifications can also simplify maintenance procedures and inventory management for aviation service facilities.

CE certification indicates that the jack complies with applicable European machinery safety requirements and engineering standards. This can simplify equipment approval and operational consistency for maintenance providers supporting international fleets or overseas operations. The included EU Declaration of Conformity confirms compliance with the European Machinery Directive and recognized machinery safety standards.
