Tronair 02A0536C0110 – 5-Ton Tripod Jack, Air Pump

The single-stage hydraulic ram design offers smooth and controlled lifting performance while reducing mechanical complexity compared to multi-stage systems. Fewer moving stages can help simplify maintenance and reduce potential wear points over time. This design also contributes to reliable lifting stability for aircraft such as the BAe Jetstream 31, Jetstream 41, and Fairchild/Dornier Merlin II. The operation manual specifies a hydraulic extension range of 22” and a 10” mechanical extension for flexible height adjustment.

The integrated velocity fuse is designed to prevent sudden ram descent in the event of a hydraulic hose or line failure. This added protection helps reduce the risk of uncontrolled aircraft lowering during maintenance procedures. According to the manual, the velocity fuse automatically locks the ram in its current position until the hydraulic issue is repaired and the system is reset. This feature adds another layer of protection beyond the pressure relief valve and ram locknut system.

The 10” mechanical extension allows technicians to position the jack closer to the aircraft jacking point before hydraulic lifting begins. This helps minimize the hydraulic stroke required during setup and can speed up lifting operations. The mechanical extension also enhances versatility when working with aircraft with varying ground clearances or jack point heights. Proper adjustment can help create more efficient and stable aircraft jacking procedures.

The translucent hydraulic reservoir allows maintenance personnel to quickly verify fluid levels without disassembling components or removing the reservoir. Easier fluid monitoring can help reduce inspection time while supporting proper hydraulic performance. The manual specifies maintaining the hydraulic fluid level approximately 1.5” below the vent opening using MIL-PRF-5606 fluid. Consistent fluid monitoring helps protect seals, pumps, and lifting performance over time.

The integrated pneumatic pump allows technicians to raise the jack more quickly than manual pumping alone, especially during the initial lifting phase. This can help reduce operator fatigue during repetitive maintenance operations in busy hangar environments. The hydraulic schematic in the manual illustrates how the air-driven pump works in conjunction with the hand pump to provide flexible lifting control. Operators can still use the manual pump when shop air is unavailable.

Simultaneous lifting helps maintain proper aircraft balance and reduces uneven stress on the airframe structure. Tronair specifically instructs operators to raise and lower all aircraft jacks together to keep the aircraft level throughout maintenance procedures. This practice is particularly important when working on business aircraft and regional turboprops with multiple jacking points. Using coordinated lifting procedures can improve both safety and equipment stability.

The Tronair 02A0536C0110 is designed with replaceable seal kits, serviceable hydraulic components, and detailed maintenance procedures to support long-term reliability. The manual recommends regular caster lubrication, annual load testing, and periodic hydraulic inspections to maintain performance. Tronair also provides dedicated replacement kits for ram seals, pump seals, and pneumatic system seals. These service-friendly features can help minimize downtime and simplify preventive maintenance.

The wide tripod base helps distribute weight evenly during lifting operations, improving overall jack stability on approved level surfaces. This design can help reduce movement during aircraft maintenance procedures while supporting safe lifting practices. The manual also advises technicians to use tail or nose stands when applicable for additional aircraft stability. Combined with the heavy-duty wheel configuration, the tripod's structure effectively balances mobility and support strength.

Correct storage procedures help protect hydraulic seals, exposed metal surfaces, and internal components from premature wear or corrosion. Tronair recommends storing the jack with the ram fully lowered and protecting the unit with a waterproof cover when stored outdoors. For low-use periods exceeding 90 days, the manual recommends fully extending the ram and applying a compatible water-repellent lubricant to exposed surfaces. Proper storage can help preserve lifting performance and extend equipment lifespan.

CE marking confirms that the jack complies with applicable European machinery safety requirements and recognized industry standards. This can help aviation maintenance organizations meet regulatory and workplace equipment compliance requirements in international operations. The Declaration of Conformity included in the manual references compliance with the European Machinery Directive 2006/42/EC and EN ISO 12100-1 safety standards. For global MRO facilities and operators, CE compliance can simplify equipment approval and procurement processes.
