Tronair 02A7844C0150 – 30-Ton Tripod Jack, Air Pump

The Tronair 02A7844C0150 is designed for demanding aircraft maintenance operations on large business jets and commercial aircraft. With a 60,000-lb lifting capacity and OEM approvals for aircraft, including the Bombardier Global series, Boeing 707/717/727, and MD-80 family aircraft, the jack supports a wide range of maintenance environments. Its heavy-duty tripod structure helps provide stable lifting during inspections, landing gear work, and structural servicing procedures. The jack’s aircraft-specific approvals also help maintenance teams align with manufacturer-recommended ground support equipment practices.

The integrated pneumatic air pump helps technicians raise the jack more quickly during initial lifting operations, reducing manual pumping effort and improving workflow efficiency. Since the air pump is factory-installed, maintenance crews do not need to add separate pneumatic lifting accessories or aftermarket components. The hold-to-run air valve also provides controlled ram movement by stopping upward travel immediately when the operator releases the lever. This combination of speed and control can help reduce aircraft downtime during maintenance operations.

The velocity fuse is designed to prevent sudden ram lowering in the event of a hydraulic line failure. This important safety component helps protect both aircraft structures and maintenance personnel during lifting operations. If a hydraulic issue occurs, the fuse automatically restricts movement until the system is repaired and reset in accordance with Tronair procedures. Safety backup systems like this are especially valuable when lifting large aircraft with high structural loads.

Operators should raise and lower all aircraft jacks simultaneously to help maintain proper aircraft balance throughout the jacking process. Uneven lifting can create excessive stress on aircraft jacking points, landing gear structures, and surrounding airframe components. The manual also recommends using a tail or nose stand for additional stability when applicable. Following coordinated lifting procedures helps improve overall aircraft safety during maintenance operations.

The 02A7844C0150 provides a 46” minimum height and up to 89.5” of maximum lift height, allowing technicians to accommodate varying aircraft jacking point positions. This flexibility supports maintenance procedures ranging from wheel and brake servicing to landing gear inspections and structural access. The combination of hydraulic and mechanical extension also helps technicians position the jack more precisely before lifting begins. A versatile lifting range can reduce the need for multiple jack configurations in mixed-aircraft maintenance facilities.

Tronair recommends checking hydraulic fluid levels before each use, lubricating casters every three months, and performing annual capacity testing at 105% to 110% of the rated load. The manual also advises extending the ram every 90 days during low-use storage periods and applying a compatible water-repellent lubricant to protect seals and exposed surfaces. Routine maintenance helps reduce wear on hydraulic components and supports long-term lifting reliability. Proper servicing is especially important for high-capacity aircraft jacks used in busy maintenance operations.

The jack operates at approximately 64 dB(A) at a distance of 120” under recommended inlet pressure conditions, helping reduce excessive workplace noise in maintenance environments. Lower equipment noise can improve technician communication and overall working conditions inside hangars and service bays. Reduced noise exposure may also support compliance with workplace safety and occupational health standards. Quiet operation is especially helpful in enclosed maintenance facilities where multiple pieces of ground support equipment are used simultaneously.

The tripod frame distributes aircraft loads evenly while providing a stable lifting platform for heavy maintenance applications. Heavy-duty swivel casters allow technicians to reposition the jack more easily around crowded hangars and aircraft parking areas. Tronair also specifies that the casters are designed to carry the weight of the jack itself, while the tripod legs support the aircraft load during lifting. This design helps improve both mobility and operational stability.

MIL-PRF-5606 hydraulic fluid is widely used throughout the aviation industry because of its dependable low-temperature performance and compatibility with many aircraft maintenance systems. Using approved aviation hydraulic fluid helps maintain consistent lifting performance and protects internal hydraulic seals and components. Tronair specifically designs the jack’s hydraulic system around this fluid specification to support reliable operation in a variety of maintenance environments. Standardized fluid compatibility can also simplify maintenance procedures for aviation service teams.

The CE marking indicates that the Tronair 02A7844C0150 complies with applicable European machinery safety directives and recognized safety standards. This compliance can help support use in international maintenance facilities and multinational aviation operations where CE-certified equipment may be required. Meeting recognized safety standards also reinforces confidence in the jack’s engineering, operational safety features, and manufacturing quality. For global aviation operators, CE compliance can simplify equipment approval and procurement processes.
