A portable trailerable vehicle capable of lifting and towing disabled vehicles and when stationary functioning as a crane to move movable objects to desired locations about the rotational axis of the upright standard. The upright standards and the tongue members are pivotally relative to each other to extend in the same direction or opposite directions. When the unit is collapsed a boom extends upwardly from the standard and a cable extending rearwardly therefrom allows the unit to perform pulling operations as in the straightening of body parts of vehicles. The height of the pulling action is variable with the ground support wheels used. A jack arm may be pivotally connected to the cross frame with a cable connected to the upright standard for use of the unit as a jack. Desired platform structures may be mounted on the outer end of the jack arm. For long lifting distances a winch cable may supplement the crane lifting cable. The transport wheels may be moved between raised and lowered positions through 180 DEG pivotal action with the second set of wheels being stationary on the bottom side of the cross frame or on the wheel mounting arm opposite the first set of wheels. Also, the second set of wheels may be pivotal with the tongue members to move between downwardly and upwardly extending positions. The upper end of the upright standard may alternatively include a light unit to be seen over a disabled vehicle being towed or an extension tongue unit for moving the unit when the upright standard is horizontally disposed. A stabilizer arm extends outwardly from the tongue members and includes a jack having vertically spaced apart mounting brackets for use depending on which set of wheels are in ground engagement. The vertical standard is rotatable between positions substantially perpendicular to the cross frame while adjustable stops permit 360 DEG rotation.
