An overthrow shovelling machine has a shovel mounted between rocker arms that are caused by a winch chain acting on a beam between the arms to roll back on tracks on the chassis of the machine to come into abrupt abutment with stops on the chassis so that the contents of the scoop are ejected therefrom, and in such a machine there is provided between the beam, which is rotatably mounted in the arms, and each arm a tensionable shock absorber. Each shock absorber comprises a pin 1 mounted on the associated arm 8 and slidably carrying a block 2 that is recessed to receive a projecting part 3 of the beam and bears against a coil spring 4 surrounding the pin. One end of the pin is threaded and engages in an internally threaded sleeve 6 secured in a bearing bracket 7 of the arm. The sleeve is also externally threaded to receive a nut 5 against which the spring 4 abuts. The other end of the pin is so mounted in a bearing bracket 10 on the arm that rotation of the pin will cause it to have an axial movement to thus vary the position of the block 2 between the brackets 7, 10 to effect the operation of the shock absorber. Tension of the spring 4 is also regulatable by adjustment of the nut 5 on the sleeve 6.
