A self propelled reaching type mobile loader includes a mobile vehicle which has an articulated body and frame and self leveling wheels. The front portion has a supporting frame with a cab enclosing the front end thereof and has a suitable motor means for operating the vehicle and loading components. A pair of pivot supports are laterally spaced on the frame adjacent the top of the cab and support a pair of pivoted supporting lever members each having a pair of arms rigidly extending at an angle to each other. One of the arms on each of the supporting lever members is supported for pivotal movement on the pivot supports and has an initial position extending along the top of the cab with the angularly extending arm extending substantially vertically in front of the cab. A pair of supporting boom members are supported on each of the angularly extending arms of the supporting lever members and movable longitudinally thereof. A load carrying carriage is supported on the lower ends of the boom members. The load carrying carriage includes pivoted members movable to clamp or secure the load carried thereon. Actuating means comprising fluid operated cylinders are provided for moving the various components. A fluid operated cylinder operates the pivoted supporting lever members to pivot the boom members between a vertical position and an elevated position. Another cylinder extends and retracts the boom members in any selected pivotal position. Other cylinders pivot the supporting carriage and operate the load securing members.
