ABSTRACT:
A hydraulic ram assembly adapted to move parts of a conveyor between a number of pre-defined positions. In one embodiment of the invention, the hydraulic ram assembly consists of a single hydraulic ram, pivotally coupled at one end to the chassis of a trommel, and pivotally coupled at the other end to at least one of a number of mechanical linkages. The mechanical linkages are configured to link the hydraulic ram and at least two parts of a trommel conveyor. At least one mechanical linkage is lockable and unlockable such that in operation, the hydraulic ram can move the parts of the trommel conveyor between (a) a first, lowered, extended, operational position; (b) a second, raised, extended, operational position; and (c) a third, folded, retracted position, suitable for transportation.
