ABSTRACT:
Hauling and cutting equipment includes a conveyor trough having a longitudinal side wall on each side with a support rail structure on at least one side having a chain guide groove therealong through which a endless link chain extends. A cutting machine overlies the trough and is guide on the rail structure and includes a drive on one side with a sprocket or chain wheel which has teeth which engage in horizontally disposed links of the link chain. The space between the teeth accommodates the vertically disposed links of the chain. The link chain comprises long horizontal links and short vertical links which are shorter than the horizontal links. The clear division of the vertical links correspond to the double link diameter of the horizontal links except for a mall clearance for movement play. The engagement division of the chain wheel is matched to the length of the vertical links.
