Product Description
The Columbus 3507-56 is a single-acting 35-ton alligator axle jack designed for standard aircraft wheel, tire, and brake changes. The cylinder head is mounted on a T-frame with three casters and comes with manual and air-powered pumping units. The jack is also available with an optional pressure gauge assembly.
The Evac-U-Tract feature utilizes the air or nitrogen supply being used to raise the jack. Once activated, the air supply automatically retracts the ram back down inside the cylinder assembly. This retraction facilitates the easy removal of the axle jack from under the aircraft jacking point. The same retraction permits the use of the cylinder rain cover, which protects the cylinder assembly from physical and environmental damage.
