<p>The disposal of rubbish (trash, garbage), and other waste materials, is nowadays effected in a properly-designed tip (dump) so constructed and lined that none of its contents can in any way affect the ambient conditions. The required impervious lining layer comes in rolls, each of which is a long, heavy, sheet of material. The dispenser apparatus can be "rigidly" attached to a tractor's (conventional) three-point mounting. A long beam 34, or framework of beams, having roughly centrally thereof a three-point mounting 39 by which it can be attached behind a tractor 32 clear of the ground, the beam 34 having normally-disposed end plates 35 between which there is borne a support rod 26 carrying a roll 27 of liner material. Preferably the beam 34 is associated with positioning control device 62,63 that can be used to adjust the lateral angle of the lower three-point mounting linkages 61, and so move the roll 27 to either side to modify where the liner is laid.</p> |
