    Abstract: A vehicle moving apparatus comprises a U-shaped, horizontally oriented, rigid frame having a transverse base frame joined at opposing ends thereof with spaced-apart, longitudinally oriented side frames. Frame wheels are engaged with the rigid frame for support and movement over a surface. The base frame and the side frames, together, define a vehicle space for placement of a vehicle wherein the vehicle is supported on its wheels. Each one of the side frames provides a proximal roller arm and a spaced apart distal roller arm. The arms are able to pivotally rotate between a stowed position within one of the side frames and a deployed position normal to one of the side frames. The arms are facilitated for adjustment of spacing between them, thereby enabling contact between the roller arms and the vehicle's wheels for lifting the vehicle onto the roller arms so that the vehicle may be moved to a designated location.

  • Patent number: 5732960
    Abstract: A dolly for lifting and transporting an automobile. The dolly is provided with a generally U-shaped frame including a base member and a pair of arm assemblies pivotally attached thereto. Each of the arm assemblies includes a load-bearing arm extending at substantially right angles from the base member and a torsion arm secured to the load-bearing arm. A pry bar is removably attached to the torsion arm for pivoting the load-bearing arm, which engages the wheel assembly of the automobile, to lift and transport the automobile. Secured to each of the load-bearing arms are casters to facilitate pivoting of the load-bearing arm and to provide for movement of the dolly over the ground surface. Latching mechanisms secured to the base member selectively secure the arm assemblies in a fixed position in which the automobile is in an elevated position and the casters are in rolling engagement with the ground surface.

  • Patent number: 5336037
    Abstract: A towing vehicle for maneuvering airplanes without draw tongue, has a chassis (5), which exhibits a fork-shaped receiver space between the wheels of one wheel axle, in which a gripping and retracting device (28, 68) is attached that can be retracted and extended and works together with a lifting device, by means of which the nose wheel (24) of the airplane can be grasped and pulled onto a scoop (14) that can be raised and lowered relative to the chassis. In it, only a single scoop (14) is present to support the nose wheel (24) in the area of the nose wheel load line of application to prevent clamping and deformation forces on the nose wheel (24) during the retraction procedure or during raising. The scoop can be tipped around a horizontal axle attached to the chassis and its tipped position relative to the chassis can be adjusted by control.

  • Patent number: 5244331
    Abstract: Apparatus for positioning a rotary member such as a vehicle wheel at a balancing machine in such a way that the rotary member can be lifted into a position, at the level of the balancing machine measuring spindle, in which the longitudinal center lines of the measuring spindle and the rotary member are aligned with each other and the rotary member can be moved concentrically relative to the measuring spindle. The apparatus has two equal-length positioning arms which are pivotally connected at an apex point in a scissor-like arrangement and which are pivotable uniformly relative to each other about their connecting point in a plane which is perpendicular to the measuring spindle. The positioning arms connecting point is displaceable along a line which is perpendicular to the longitudinal center line of the measuring spindle and which coincides with the line bisecting the angle formed by the positioning arms.

  • Patent number: 5161931
    Abstract: Improved wheel and tire handling apparatus or structure including a base member adapted for movement on relatively level surfaces by the use of rollers and casters. A vertically moveable second section is adapted for movement up and down on uprights of the base member and a jack is mounted in between the base member and the second section to raise and lower the second section relative to the base member. The second section is further provided with an elongated axle extending across the second section on which are axially slideably mounted two tines. The tines can be restricted as to axial movement by the use of manually fixable slideable collars on the axle to prevent the tines from moving away from each other when a wheel and tire are received thereon. Rollers are provided for the tire receiving surfaces of the tines to facilitate rotational movement of the wheel and tire to align the wheel with lug bolts when remounting the wheel and tire.

  • Patent number: 5054714
    Abstract: The aircraft tractor arrangement maintains a uniform degree of reliability with which the nose wheel landing gear, which is standing on a lifting platform that is arranged on the front part and extends into a recess (26), is held down on the surface of the lifting platform which supports the nose wheel landing gear at different nose wheel diameters.Each telescoping rod (30) is hinged (40, 44, 46) to the front part (10.1) directly in the front. A connecting hydraulic cylinder (42) is provided in the rear. The hydraulic cylinder (46) for longitudinal adjustment, and also the hydraulic cylinder (36) for moving the holder (34) on the fixed part (30.1) of the telescoping rod (30) associated with it are arranged ridgedly.This arrangement allows an adjustability in height of the two rear tow arms and at the same time of the front holders, which can come into contact with the two desired zones of the wheel circumference, regardless of the nose wheel diameter.

  • Patent number: 5051052
    Abstract: The present invention pertains to an aircraft tractor without tow-bar. The arrangement avoids relative movement between the nose wheel of the aircraft and the tractor lifting platform by making the lifting platform (24) rotatable around a longitudinal axis (30) of the chassis, which axis is horizontal when the chassis is extended, and by making displaceable the transverse tow arms (38) and/or the holders (42) at right angles to this longitudinal axis (30). The tires of an oblique nose wheel landing gear of an aircraft being towed in a curve are handled very gently, because the tractor parts (24, 38, and 42) that are in contact with the nose wheel landing gear are able to follow the movements of the nose wheel landing gear and to adjust to its instantaneous position.
