Tronair 02-7935C0000 – Proof Load Fixture for Tripod Jacks, 50-Ton Capacity (CE)

A proof load fixture is used to verify the hydraulic load capacity and the pressure relief valve performance of aircraft tripod jacks. By applying a controlled test load, it ensures the jack meets required load thresholds before being returned to service. This testing helps confirm structural integrity and hydraulic performance. Routine proof load testing supports overall aircraft ground support equipment safety.

The Tronair 02-7935C0000 Proof Load Fixture allows technicians to confirm that tripod jacks meet required proof load percentages during annual inspections. The digital load indicator ensures measurable, repeatable test results. Verifying jack performance reduces the risk of underperforming or improperly adjusted pressure relief valves. This process supports regulatory compliance and safe aircraft maintenance operations.

During testing, the digital load indicator should display approximately 105% to 110% of the jack’s rated load capacity. This confirms that the pressure relief valve activates within the proper performance range. If the jack does not meet this threshold, corrective maintenance may be required. Accurate measurement ensures dependable load certification.

Tronair recommends calibrating the load cell, cable, and digital load indicator as a complete unit annually, or as required by local directives. Regular calibration ensures the proof load fixture delivers precise and reliable readings. Maintaining calibration records is essential for audit readiness and quality assurance programs. Consistent calibration protects the integrity of load verification procedures.

The unit requires periodic inspection and annual calibration of the load cell assembly to maintain accuracy. Technicians should also inspect pins, struts, and mechanical components for wear or damage. Keeping the fixture clean and properly stored extends service life. Preventive maintenance minimizes downtime and protects your investment in test equipment.

No. The manufacturer clearly states that the product cannot be modified without written approval from Tronair, Inc., and that unauthorized modifications void all warranties. Only Tronair OEM replacement parts should be used. Maintaining the original configuration ensures safe operation and preserves liability protections.

The Tronair 02-7935C0000 Proof Load Fixture has a maximum load capacity of 100,000 lbs (50 tons). This capacity allows it to support proof testing for heavy-duty tripod jacks used in commercial and military aviation environments. The high load rating ensures suitability for demanding maintenance facilities.

The fixture utilizes a digital load indicator paired with a 50-ton load cell for accurate force measurement. The indicator provides clear load readings during testing and supports precise verification of hydraulic relief performance. This electronic measurement system enhances repeatability compared to mechanical-only testing methods.

Tronair warrants that the product is free of manufacturing or material defects for one year from the date of shipment to the original customer. The warranty covers the repair or replacement of defective components. Normal maintenance parts and items covered by component manufacturers are subject to separate terms. Understanding warranty limitations helps facilities plan long-term support.

Aircraft tripod jacks support significant aircraft weight during maintenance, making proper load verification critical. Proof load testing confirms that hydraulic systems and pressure relief valves function within specified limits. Identifying performance issues before a jack is used prevents potential equipment failure under load. Routine testing protects technicians, aircraft, and overall maintenance operations.
