  • Patent number: 10569903
    Abstract: An apparatus including a platform, casters attached to the platform, and a carriage supported by the platform is described. The carriage includes a left arm, a right arm, and an actuation mechanism. The left arm can pivot about a left lateral axis, and the right arm can pivot about a right lateral axis. The actuation mechanism allows a distance between a proximal end of the left arm and a proximal end of the right arm to be modified. Increasing the distance causes a distal end of the left arm and a distal end of the right arm to swing towards each other. Decreasing the distance causes the distal end of the left arm and the distal end of the right are to swing away from each other. The apparatus provides a convenient means by which to move a helicopter equipped with skids while the helicopter is on the ground.

Devices for extending and retracting the front wheels are provided. The instant kneeling dolly with ramp brake may be used singly, in pairs, or in whatever grouping(s) desired. In operation, a vehicle is rolled onto kneeling dollies with ramp brake, until one vehicle wheel is disposed on a respective kneeling dolly with ramp brake. Due to the swivellable attachment of the front and rear wheels, each kneeling dolly with ramp brake is free to travel in any desired direction, and thus the vehicle supported by the kneeling dollies with ramp brake may be pushed in any direction. This flexibility in movement helps relieve congestion and maximize floor space in garages, hangars, etc.

  • Patent number: 6139250
    Abstract: Wheel lift tow device for a tow truck includes a centrally located extendable support beam having a cross bar pivotably attached to it, so that it can be oriented obliquely for towing obliquely placed disabled cars. The telescoping slider arms of the cross bar provide lateral movement for a pair of swivel arm claws, or claws, which cradle and lift a pair of wheels of the disabled vehicle. The swivel arm scoops are rotatable about a pivot on each telescoping slider arm, but in their position of use are supported by a lateral stop bracket, which supports the lateral forces of the wheel while in the cradled position and distributes the weight therefrom.

  • Patent number: 5909996
    Abstract: A wheel lift head assembly is pivotally mounted adjacent the rear end of a truck frame and is hydraulically operated for raising and lowering one end of a vehicle to be towed behind the truck. The wheel lift head assembly includes a crossbar member having a pair of hollow tubes pivotally mounted at opposite ends thereof with a pair of J-shaped wheel engaging members slidably mounted therein. A retainer is secured to an end of each J-shaped arm to prevent the withdrawal of the arm from the pivoted guide tube and a J-shaped arm provides engagement on opposite sides of the wheels of the vehicle to be towed to prevent lateral slipping of the wheels. A tiltable truck bed is mounted on the truck for pivotal movement between a horizontal position and an inclined position. At least one support post is provided at the rear of the tiltable truck bed for supporting the end of the tiltable truck bed on the ground and notches are formed in a forwardly facing surface of the support post.

  • Patent number: 5908280
    Abstract: A wheel lift apparatus for tow vehicles includes a boom extending from a tow vehicle and a cross arm connected with the boom. The wheel lift apparatus also preferably includes a pair of receivers including an inclined face mounted on opposite end portions of the cross arm and a pair of pivot members mounted on the end portions. A pair of swing arms, each of which preferably has a swivel leg, a wheel support leg and a distal leg, is mounted on the pivot members. The swing arms are pivotally movable between a storage position in which the wheel support legs each extend between the boom and one of the pivot members and towing position in which the distal legs are spaced apart from the cross arm such that the cross arm, wheel support leg and distal leg, and preferably the inclined face, define a receptacle for receiving and supporting a wheel of a vehicle for lift towing. Methods of wheel lift towing are also provided.
