Abstract: Reel lifting apparatus utilizing a truck-like vehicle having a wheeled framework with a subframe mounted on the framework. A truck bed body is mounted upon the subframe and overlies the subframe. An elongate rod-like member is provided which is pivotally mounted on the body so that it extends in a direction at right angles to the longitudinal axis of the vehicle. First and second arms are mounted in fixed spaced apart positions on the rod-like member. The arms are formed so that they are capable of carrying a reel mounted upon a spindle. A plate is secured to the rod-like member. An L-shaped member has one end of the same pivotally connected to the subframe and the other end pivotally connected to the plate. An actuator is pivotaly connected to the subframe and to the L-shaped member at a point intermediate the ends of the L-shaped member for causing the movement of the arms through an angle in excess of 135.degree.. An in-line motor drive train is mounted upon one of the arms.

Abstract: Mobile lifting equipment having a wheeled vehicle with a frame. The boom structure is mounted on the frame for rotation about a vertical axis, raising and lowering the same about a horizontal axis and for extension and retraction with respect to the vehicle. The boom structure includes an outer boom and an inner boom which is mounted for telescoping movement in the outer boom. First and second extension cylinders are carried by the outer boom for extending and retracting inner boom with respect to the outer boom. An elevation cylinder is connected to the outer boom and is provided for raising and lowering of the boom structure. An elevation control is provided for supplying hydraulic fluid to the elevation cylinder. Piping is provided for connecting the elevation cylinder to one of the first and second extension cylinders so that extension of said one of said first and second extension cylinders is limited by the amount of hydraulic fluid which has been supplied from the elevation cylinder.
