Abstract
703,194. Loading ; load-handling machines. ALLARD, P. J. M. T. Aug. 13, 1951 [Oct 3, 1950], No. 19005/51. Classes 78 (3) and 78 (4) [Also in Group XXI] To reduce the time of the cycle of operations of an excavator, particularly a grab bucket excavator, when the tool or grab 29 is withdrawn from the excavation 42 a tray 39 is swung beneath it to receive its contents, said tray thus being swung clear of the grab to discharge said contents clear of and to one side of the machine whilst the grab is being returned into the excavation. The tray is adjustably mounted to turn about a horizontal axis 41a on a substantially horizontal arm 37, provided with a knee joint, the arm turning about a substantially vertically disposed pivot on the chassis. The tray may be duplicated on both sides of the chassis.
