  • Patent number: 11801945
    Abstract: A helicopter tug apparatus for loading, transporting, and unloading a helicopter landing skid includes a plurality of landing skid loading units. The loading units are arranged to support the landing skid, and each of the loading units includes a skid cradle with a plurality of tug rollers configured to engage the landing skid. The loading units each include a drive track, and at least one motor for operating the skid cradle and the drive track. The rollers are reverse synchronized with the drive track, such that when the drive track moves the loading unit under the landing skid, the tug rollers turn in reverse to avoid placing lateral force on the landing skid.
    Type: Grant

  • Patent number: 11312504
    Abstract: A pivoting cradle apparatus for capturing an aircraft wheel on an aircraft tug includes a cradle sized for holding the wheel, mounted on at least one pivot block and configured to pivot between a wheel loading position and a wheel retaining position. A latch mechanism is disposed under the cradle, biased to swing into an upright position wherein it seats in a notch on the cradle, locking the cradle in the wheel retaining position. A latch release mechanism is configured to urge the latch out of the upright position, and when it does so, the latch slides along the underside of the cradle as the cradle pivots down. into the wheel loading position.

  • Patent number: 10625880
    Abstract: An aircraft tug apparatus for tugging an aircraft by an aircraft tire includes a turntable on a main base portion of the tug, capable of rotational movement relative to the main base portion. A tire cradle assembly on the turntable releasably holds the aircraft tire, and a latch mechanism holds the tire cradle assembly in a position that confines the aircraft tire. A pivoting arm coupled to the main base portion extends under the turntable. The pivoting arm includes a first plunger and a second plunger extending therefrom, with the first plunger coupled to the pivoting arm using a spring assembly allowing it to move up and down relative to the pivoting arm. The spring assembly is configured such that the pivoting arm may move the second plunger to engage the latch mechanism while the first plunger is impinged by the turntable.

  • Publication number: 20190217970
    Abstract: An aircraft tug wheel cradle with a front ramp assembly and a rear gate assembly on a base plate, each hingedly mounted and movable between a wheel-mounting position and a wheel-confining position. A first side clamp and a second side clamp are hingedly coupled to the base plate on opposing sides of the vehicle wheel, and movable between a lower position and an upper position coinciding with the wheel-confining position. The first side clamp and the second side clamp are each preferably hingedly attached to the base plate at other than an ninety degree angle in order to grasp the vehicle wheel, such that the vehicle is prevented from lateral and upward, as well as front and back movement.
