ABSTRACT:
An elongated upright motor extendible and retractable support member is provided including relatively extendible upper and lower end sections and the upper end section is pivotally mounted from a rear upper portion of body of a tow truck for oscillation relative thereto about a first horizontal axis extending transversely of the chassis and the upper end section. The support member is swingable between a generally vertical lowered position and a raised inclined position with the lower end section swung outwardly and upwardly from the vehicle rear end and a motor extendible and retractable light and tow arm having relatively extendible front and rear ends as provided and the front end is mounted from the lower end section of the support member for oscillation relative thereto about a second horizontal axis extending transversely of the arm and the lower end section. The arm is swingable between a lowered position with the arm disposed generally 90.degree. relative to the support member and projecting rearwardly therefrom and a raised position closely parallel the rear side of the support member. The rear end of the arm has a cross beam oscillatably supported therefrom and the opposite ends of the beam include structure for cradling the underside peripheral portions of the opposite side wheels of the vehicle to be towed. Further, motor structure is connected between the vehicle chassis and the upper end section of the support member for adjustably swinging the latter between the raised and lowered positions thereof.
