QUESTIONS & ANSWERS
The 1074-8000 Jack Load Test Unit is designed for static load testing of tripod and axle jacks from any manufacturer. It provides precise measurement of lifting loads to confirm that hydraulic jacks perform safely and meet rated capacity. This tester ensures compliance with maintenance standards for aircraft jacks used in both military and commercial aviation environments.
The tester uses an electronic load cell integrated into the adjustable load beam. The results are displayed on a digital electronic readout and control box, allowing precise measurement of applied loads in real time. This digital system minimizes operator error and provides repeatable, traceable results for inspection documentation.
The adjustable load beam can be raised or lowered in 10” increments to accommodate jacks of different heights and configurations. It’s operated by an electrical hoist system, which simplifies setup and reduces manual handling effort. The load beam and locking pins are easily accessible via the integrated ladders and safety harness system.
Safety is ensured through dual access ladders, safety harnesses, and locking pins for load beam positioning. The entire system is coated in Skydrol-resistant paint, which protects against hydraulic fluid damage commonly encountered in maintenance hangars. These features make it suitable for extended use in demanding aviation environments.
Routine maintenance includes verifying calibration of the load cell, inspecting safety pins and ladders, and ensuring the electrical hoist operates smoothly. Tronair recommends periodic testing of electronic controls and cleaning of Skydrol-resistant surfaces to maintain reliability and safety. Proper maintenance ensures consistent load accuracy and extends equipment lifespan.
The digital control box provides precise, easy-to-read load measurements during testing. Operators can control the hoist directly from the panel, allowing efficient and safe raising or lowering of the load beam. This integration eliminates the need for multiple control points and helps streamline the testing workflow.
Built for harsh industrial and aviation environments, the 1074-8000’s heavy steel frame and corrosion-resistant coating allow continuous outdoor or hangar use. Its rugged construction ensures reliable performance despite exposure to hydraulic fluids, temperature fluctuations, and heavy use cycles.
Columbus Jack provides a one-year warranty covering defects in materials and workmanship. The warranty assumes proper operation, calibration, and maintenance as outlined in the product manual. Tronair’s global service network supports parts, maintenance, and warranty claims worldwide.
