The Tronair 02A7845C0120 is a 10-Ton (20,000 lb) hydraulic aircraft tripod jack engineered to lift aircraft from the forward fuselage or main wing jacking points during maintenance, inspections, and ground operations. The three-stage hydraulic design provides controlled lift and positive lock at any extension height. A factory-installed air pump allows rapid initial extension without additional equipment. CE-marked for compliance with European aviation safety standards. OEM-specified for Bombardier CRJ700, CRJ705, CRJ900 and others. Also approved for Embraer Legacy 450, Legacy 500 and others.

Safety Features
- Ram Lock Nut: Prevents the lowering of the ram. The ram lock nut must be lowered as the aircraft is being lifted. Ram lock nuts must be kept within 2" of the stop while raising the aircraft.
- Hold-to-Run Air Valve: Requires the operator to hold the air valve lever to raise the ram using the air pump. Releasing the air valve lever stops the upward movement of the ram.
- Lock Nut Retention Ring: Prevents the lock nut from being unscrewed from the second stage.
- Pressure Relief Valve: Prevents overload during raising operations.

QUESTIONS & ANSWERS
The Tronair 02A7845C0120 is a 10-ton, three-stage aircraft tripod jack designed to safely lift aircraft by the fuselage or main wing for inspection, maintenance, or repairs. It uses a combination of manual and pneumatic pumps to raise aircraft smoothly and securely. The jack must always be used in conjunction with the proper aircraft jack pads and lifting points specified by the aircraft manufacturer.
Before each operation, inspect the jack for any visible damage, loose fittings, or leaks. Ensure hydraulic rams are fully retracted, verify that all nuts and bolts are tightened, and check that the hydraulic fluid level is within 1/2" of the reservoir vent. Refill as needed using MIL-PRF-5606 hydraulic fluid.
The air pump requires a clean, dry air source with a supply pressure between 90 and 100 PSI (6.21 to 6.89 bar). Before connecting, ensure the shop air needle valve is closed, then open it gradually during operation. Overpressurization beyond 125 PSI should be avoided to maintain system integrity.
Tronair recommends annual load testing of all tripod jacks to ensure safe operation. During testing, always jack against a load – not the jack itself – and do not exceed 105% to 110% of the rated capacity. Following Tronair’s function load test guidelines helps verify hydraulic integrity and mechanical stability.
Maintenance should be performed in a clean, debris-free workspace using proper tools and good workmanship practices. Regularly inspect O-rings, backup rings, and locknuts for wear or damage, and replace them as needed. Hydraulic surfaces should be treated with a rust-preventive oil that is compatible with Buna-N seals when the jack is not in use.
Store the jack with the ram fully retracted in a clean, dry environment between -4°F and 122°F (-20°C to 50°C). For outdoor conditions, cover the jack completely with a waterproof tarp or canvas. This prevents corrosion and contamination of hydraulic seals and metal components.
The jack can be moved manually on its built-in casters or lifted with a crane using straps through the tripod’s top section. For shipping or relocation, it may also be handled with a forklift placed under the lower tripod support. Always secure the jack with appropriate strapping to prevent movement during transit.
Tronair warrants its products against manufacturing and material defects for one year from the date of shipment, covering the repair or replacement of defective components. Replacement parts are covered by a 90-day warranty from the date of shipment. Normal wear items, or parts altered without authorization, are not covered under warranty.
Always secure the load using the ram locknut before working under an aircraft, and never place hands near the ram threads during lowering. The jack should be used only on a hard, level surface, and all jacks supporting the aircraft must be raised and lowered simultaneously. Failure to follow proper safety procedures may result in injury or damage to equipment.
