02-7813C0100 – Tronair Hydraulic 12-Ton 2-Axle Main Landing Gear (MLG) Jack
Available now on the Airparts.aero Marketplace.
The Tronair 02-7813C0100 is a heavy-duty, professional-grade hydraulic floor jack specifically engineered for lifting the Main Landing Gear (MLG) of mid-to-large business jets and regional aircraft. Featuring a robust 12-ton capacity and a unique 2-axle, 4-wheel chassis, this jack provides the stability and lateral load resistance required for tire, brake, and strut maintenance on the hangar floor. Unlike standard automotive jacks, the 02-7813C0100 is designed with a low-profile entry height and a high-reach hydraulic ram, allowing it to interface perfectly with aircraft-specific jack pads without interfering with fairings or gear doors.
Constructed from high-tensile structural steel and finished in Tronair’s signature high-visibility chemical-resistant powder coat, the 02-7813C0100 is a staple of professional Flight Base Operations (FBOs) and MRO facilities worldwide. The jack utilizes a dual-piston manual hydraulic pump for rapid extension to the jacking point, followed by a high-pressure stroke for effortless lifting of the aircraft's weight. Its 2-axle design is a critical safety feature, ensuring the jack remains centered and stable even if the aircraft shifts slightly during the lifting process.
Key Features
12-Ton (24,000 lbs) Lifting Capacity: Engineered with a significant safety factor to handle the maximum ramp weights of common business jets like the Challenger and Gulfstream series.
Dual-Axle Stability: Features four heavy-duty casters on two independent axles, providing superior floor contact and preventing the "tipping" risk associated with single-axle 3-wheel jacks.
Precision Manual Hydraulic Pump: Features a side-mounted pump handle with a controlled-release valve for ultra-smooth descent, preventing structural shock to the landing gear during lowering.
Low-Profile High-Reach Geometry: Designed to slide under the lowest MLG strut points while providing enough vertical travel to fully clear the tires for removal.
Interchangeable Jack Pad Interface: Compatible with a variety of Tronair and OEM jack adapters (round or concave) to ensure a secure, non-slip interface with the aircraft's jacking point.

Applications
The 02-7813C0100 is utilized for Aircraft Ground Support Maintenance. Its primary roles include:
Tire and Brake Changes: Providing the necessary clearance to remove and install heavy wheel assemblies.
Strut Servicing: Lifting the axle to perform nitrogen/oil servicing or seal replacements.
Wheel Bearing Inspection: Allowing for free-rotation of the wheel during annual or 100-hour inspections.
Why Choose 02-7813C0100?
Choosing a genuine Tronair 02-7813C0100 ensures the safety of both the technician and the multimillion-dollar airframe. Industrial "shop jacks" are not rated for the side-loading or the specific center-of-gravity requirements of an aircraft. The Tronair 12-ton jack is designed with a broad footprint that compensates for the slight "arc" a landing gear strut takes as it is lifted. Furthermore, its hydraulic seals are specifically chosen to resist Skydrol and other aggressive aviation fluids that would cause standard rubber seals to dissolve and fail.
The 02-7813C0100 operates on the principle of Pascal’s Law, where pressure applied to a confined fluid is transmitted undiminished in all directions. In this 12-ton system, a small-diameter pump piston creates high pressure that acts upon a large-diameter ram, resulting in massive mechanical advantage. The dual-axle geometry is critical for maintaining the jack’s verticality; as the aircraft is lifted, the strut moves in a slight radius. The 4-wheel chassis allows the jack to "crawl" slightly to stay perfectly aligned under the jack pad, preventing the dangerous "side-loading" of the ram that can lead to seal blowouts or structural collapse.
Note: This is a heavy-duty maintenance tool. Prior to use, inspect the hydraulic fluid level and check for leaks. Ensure the jack is used on a level, weight-rated concrete floor. Never work under an aircraft supported only by a jack; always utilize secondary jack stands or "locks" if available. Maintenance, including seal replacement and load-testing, should be performed annually by a qualified GSE technician.
