02-7825-0110 - Tronair 02-7825C0110 – 20-Ton Axle Jack

The Tronair 02-7825C0110 is a 20-ton aircraft axle jack designed to safely lift aircraft during maintenance procedures. It is commonly used for servicing landing gear, tires, and brake systems on select Bombardier Learjet aircraft. Its compact design and high lifting capacity make it ideal for hangar and line maintenance operations. This axle jack supports efficient, controlled lifting in professional aviation environments.

The single-stage telescoping ram provides a straightforward, reliable lifting mechanism with fewer moving parts than multi-stage systems. This design helps reduce maintenance requirements while maintaining consistent lifting performance. It also improves operational stability by minimizing internal complexity. For technicians, this means dependable lifting with reduced risk of mechanical issues over time.

The quick-action mechanical extension allows technicians to rapidly position the axle jack close to the aircraft jacking point before hydraulic lifting begins. This reduces the number of pump strokes required and speeds up setup time. It also improves efficiency when working on multiple aircraft or performing routine maintenance tasks. Faster positioning contributes to smoother, more productive workflows.

The preset pressure relief valve is designed to prevent overloading by automatically limiting hydraulic pressure within the system. This protects both the aircraft and the jack from excessive force during lifting operations. It also helps maintain consistent performance without requiring manual adjustment. Built-in pressure control is essential for safe and compliant aircraft maintenance.

Maintaining the correct level of MIL-PRF-5606 hydraulic fluid ensures smooth operation and reliable lifting performance. The manual recommends checking fluid levels with the ram fully collapsed to ensure accuracy. Clean hydraulic fluid helps prevent internal wear, contamination, and pressure loss. Proper fluid maintenance ultimately extends the service life of the axle jack.

Operators should always position the axle jack on a hard, level surface and ensure the jack pad is properly aligned with the aircraft lifting point. The reservoir vent screw must be opened before operation to allow proper hydraulic function. Hands and tools should be kept clear of the jack pad during lifting to prevent injury. Following these standard safety practices helps ensure controlled and secure aircraft lifting.

The included 1” and 2” spacer blocks allow technicians to adjust the closed and extended height of the axle jack for different aircraft configurations. This added flexibility helps ensure proper alignment with various jacking points. Spacer blocks are especially useful when working with aircraft that have limited ground clearance or unique geometry. They enhance adaptability across multiple maintenance scenarios.

No, the Tronair 02-7825C0110 axle jack is supplied with spacer blocks as standard. Certain Tronair axle jack models include an “-A5” suffix in the part number, which indicates that spacer blocks are not included. If your application requires a configuration without spacer blocks, please verify the correct part number before ordering.

No, the Tronair 02-7825C0110 axle jack does not include Learjet 60 adapters. However, when paired with the appropriate adapters (K-4229 and Z-2639), the jack is suitable for use on the Learjet 60 aircraft.

Routine maintenance includes inspecting seals, replacing worn O-rings, and keeping the hydraulic system clean and properly filled. The manual also recommends periodic load testing and fluid replacement to maintain performance. Keeping components free of debris and corrosion helps prevent premature wear. Regular servicing ensures the axle jack remains reliable and ready for demanding aviation use.
