02-7809-0100 - Tronair 02-7809C0110 – 10-Ton Tripod Jack

The primary purpose of this 10-ton tripod jack is to safely lift aircraft for maintenance and servicing procedures. According to the operation and service manual, it is designed specifically for aircraft lifting within its rated capacity. Proper use ensures stable access for inspections, landing gear service, and other under-aircraft maintenance tasks.

The 02-7809C0110 uses MIL-PRF-5606 hydraulic fluid, a common aviation-grade fluid specified for many aircraft maintenance applications. Using the correct fluid helps maintain seal integrity and proper hydraulic performance. Always confirm the fluid condition and level before operation.

This Tronair jack incorporates two telescoping hydraulic rams, allowing a wide extension range while maintaining stability. The staged extension ensures controlled vertical lift, with the largest ram extending first. This design provides efficient height adjustment for aircraft with varying jack point clearances.

The jack is equipped with mechanical ram lock speed nuts that must be lowered during lifting operations to secure the load. These locknuts act as user-operated safety devices to prevent unintended descent. Proper engagement of the locknuts is critical for safe aircraft jacking.

If equipped with the air-driven pump, the maximum air-drive system pressure is 125 PSI (8.6 bar). Exceeding this limit can damage the pneumatic system or compromise safe operation. Shop air connections should always be verified before use.

Annual load testing is recommended to verify safe operation and rated capacity. Testing should not exceed the rated capacity by more than 5–10%. Routine load testing helps ensure continued compliance with aviation safety standards.

If the jack is not used regularly, it should be fully extended and retracted every 90 days to exercise the seals and prevent corrosion. Hydraulic fluid should be kept clean and at the proper level. Protecting the jack from contaminants such as Skydrol or cleaning chemicals also helps preserve seals and internal components.

Tronair products are warranted against manufacturing or material defects for one year from the date of shipment to the original customer. Replacement parts and service support are available directly from PJi. For warranty claims, model and serial number information is required.

Yes. The Tronair 02-7809C0110 10-Ton Tripod Jack is approved for use with the Sikorsky HH-60W. Its rated 20,000-lb (9.07 metric ton) capacity and two-stage design make it suitable for this aircraft when used in accordance with the applicable maintenance manual and proper jacking procedures. Always verify aircraft-specific jack point requirements before lifting.
