1. A device for lifting and loading materials comprising:

  • a frame including a storage container having an inlet opening that is located above ground level;

    a pick-up arm for engaging material at ground level for loading through the inlet opening of storage container;

    a lift assembly for the pick-up arm includinga lift arm connected at one end portion to the frame and at another end portion to the pick-up arm;

    first actuating means for swinging the pick-up arm relative to the lift arm about an axis that is generally perpendicular to the ground to bring the pick-up arm into a close-in position along the section of the storage container where the inlet opening is located and a outreaching position spaced away from that section; and

    second actuating means for moving the lift arm relative to the frame between a load level, at which the pick-up arm is located at a selected height near ground level, and an off-load level, at which the pick-up arm is raised to the level of the inlet opening; and

    first controlling means interconnecting the first and second actuating means for automatically moving the pick-up arm into the outreaching position as the lift arm moves toward the load level, thereby permitting access to materials located away from the storage container, and for automatically moving the pick-up arm into the close-in position as the lift arm moves toward the off-load level, thereby facilitating the off-loading of such materials through the inlet opening and into the storage container.
