Tronair 02-7925C0100 – 25-Ton Axle Jack

The three-stage telescoping ram allows the Tronair 02-7925C0100 axle jack to achieve a substantial lifting range while maintaining a very low closed height. This combination is especially useful for aircraft with limited ground clearance around the landing gear. The staged extension design also helps provide smoother lifting progression and improved stability during maintenance operations. For aviation technicians, this means greater versatility when servicing multiple aircraft configurations.

The included 1” and 2” spacer blocks allow technicians to adjust the jack height for different aircraft servicing requirements. By combining the spacers, operators can increase both the closed and extended heights by up to 3”. This added flexibility helps maintenance teams properly position the axle jack under varying landing gear geometries. Adjustable height capability can also reduce setup time and improve efficiency in the hangar.

The quick-action mechanical extension allows operators to rapidly position the jack closer to the aircraft jack point before hydraulic lifting begins. This reduces the manual pumping required and speeds up maintenance setup procedures. Faster positioning can be especially valuable during tire changes, brake servicing, and other routine landing gear maintenance tasks. It also helps technicians achieve more precise alignment with the aircraft lifting point.

The preset relief valve helps protect both the aircraft and the jack from overload conditions by limiting hydraulic pressure within the system. If excessive pressure develops during lifting, the valve automatically releases pressure to maintain safe operating conditions. Tronair specifically warns against disassembling the preset relief valve to preserve factory-calibrated safety settings. This feature is critical for maintaining safe aircraft jacking operations in aviation maintenance environments.

The heavy-duty steel construction provides the strength needed to safely support large aircraft loads during maintenance procedures. Steel components also help the axle jack withstand repeated daily use in demanding hangar and ramp environments. This durable construction improves resistance to wear, deformation, and impact damage over time. For operators, rugged steel construction helps maximize equipment longevity and reliability.

Tronair recommends regular inspections that include checking for hydraulic leaks, damaged seals, loose hardware, and worn ram surfaces. The maintenance schedule also calls for annual load testing and periodic hydraulic fluid replacement to help maintain safe lifting performance. Keeping the work area clean during servicing and replacing seals when removed can help prevent contamination-related failures. Proper preventative maintenance supports dependable operation and reduces unplanned downtime.

MIL-PRF-5606 hydraulic fluid is widely used throughout the aviation industry because it provides dependable hydraulic performance across a broad range of operating conditions. The fluid offers excellent lubrication and compatibility with many aircraft maintenance hydraulic systems and seal materials. Tronair specifies this fluid for the 02-7925C0100 to support consistent lifting performance and reliable system operation. Using approved aviation hydraulic fluid also helps maintain proper equipment compliance and serviceability.

With a minimum closed height of just 5.75”, the Tronair 02-7925C0100 can fit beneath aircraft with limited axle clearance. This low-profile configuration makes the jack particularly useful for servicing business jets and other aircraft with compact landing gear arrangements. Easier positioning beneath the aircraft can reduce setup complications and improve technician productivity. Low-profile axle jacks are especially valuable during tire and brake maintenance operations.

Yes. PJi offers OEM replacement seal kits, ram seal kits, pump replacement kits, and other service components for the Tronair 02-7925C0100 jack. Access to factory-approved replacement parts helps maintenance teams keep the jack operating to original specifications. Using genuine Tronair parts can also help maintain safe operation and extend overall equipment life. The operation and service manual includes detailed parts diagrams and replacement kit listings for maintenance reference.

Aircraft axle jacks support substantial loads, so proper operator training is essential for safe lifting procedures and aircraft protection. Tronair emphasizes that employers are responsible for providing training programs that address both jack operation and aircraft-specific servicing procedures. Proper training helps technicians understand correct jack positioning, hydraulic operation, and safety precautions. Well-trained personnel can help minimize the risk of equipment misuse, aircraft damage, and workplace injuries.
