Tronair 02-7960C0100 – 25-Ton Axle Jack

The Tronair 02-7960C0100 is OEM-specified for the Gulfstream G650, G650ER, and G700, making it well-suited for the demanding maintenance requirements of long-range business aircraft. Its 25-ton lifting capacity supports safe wheel, brake, and landing gear servicing on aircraft with substantial landing gear loads. The jack’s compact footprint and low-profile design also help technicians work efficiently in crowded hangar environments and on active ramps.

The two-stage telescoping ram design allows the axle jack to achieve significant lifting height while maintaining a relatively compact closed height for easier positioning beneath the aircraft. This design provides additional lifting flexibility for aircraft with varying axle clearances and servicing requirements. According to the Tronair service manual, the jack combines hydraulic extension with a quick-action mechanical extension to streamline setup and lifting operations.

The quick-action mechanical extension allows technicians to rapidly position the jack closer to the aircraft lifting point before hydraulic pumping begins. This reduces unnecessary hydraulic travel and speeds up aircraft lifting during tire changes, brake servicing, and inspections. Faster setup can improve maintenance efficiency while also reducing operator fatigue during repetitive lifting operations.

The Tronair 02-7960C0100 is built with durable steel construction and a protective powder-coat finish designed to withstand demanding aviation maintenance environments. Its manual hydraulic operation eliminates the need for external power sources, making it practical for both hangar and remote ramp applications. The jack’s stable base design and compact form factor also support easier maneuverability around business jets and crowded maintenance areas.

Optional spacer block kits allow technicians to adjust the jack’s effective working height for different aircraft configurations and servicing needs. The Tronair K-2557 spacer block kit includes both 1” and 2” extension base blocks to help improve compatibility with varying landing gear geometries. These accessories can reduce setup complications and help position the jack more efficiently beneath approved lifting points.

Annual load testing helps verify that the axle jack can safely support its rated lifting capacity under operational conditions. Tronair recommends testing the jack annually at up to 110% of rated capacity as part of a preventative maintenance program. Regular testing helps identify wear, hydraulic issues, or structural concerns before they create unsafe maintenance conditions. This is especially important for high-capacity aircraft jacks used in frequent maintenance operations.

Routine inspections and preventative maintenance are essential for maintaining safe, reliable lifting performance. Tronair recommends regularly checking hydraulic fluid levels, inspecting O-rings and seals for wear, verifying proper ram operation, and keeping the unit clean and free of debris. The maintenance schedule also advises inspecting ram surfaces for corrosion and replacing worn seals to help prevent hydraulic leakage and jack failure.

The integrated single-speed hydraulic hand pump gives technicians precise control during aircraft lifting and lowering procedures. Controlled lifting helps minimize sudden movements that could place unnecessary stress on landing gear components or aircraft structures. The manual system also allows operators to safely lower the aircraft gradually by slightly opening the release valve after maintenance is completed.

The 02-7960C0100 is designed for use with MIL-PRF-5606 hydraulic fluid, which is commonly used throughout the aviation industry for aircraft maintenance equipment. The service manual also notes compatibility with MIL-PRF-83282 hydraulic fluid. Using approved aviation hydraulic fluids helps maintain proper seal performance, consistent hydraulic pressure, and reliable operation across a wide operating temperature range.

OEM-approved aircraft axle jacks are specifically evaluated for compatibility with certain aircraft models and their approved lifting procedures. Using an OEM-specified jack, such as the Tronair 02-7960C0100, helps maintenance teams meet manufacturer requirements for safe aircraft lifting and servicing. Properly matched lifting equipment can also help reduce the risk of structural damage, improper load distribution, or unsafe maintenance practices during wheel and landing gear operations.
