Abstract: A wheeled bogie unit is engageable with one end of a chassis of a treatment plant to support that end of the chassis above the ground for the suspended transport of the plant. The bogie unit has a chassis, at least one wheel set supporting the chassis, a lifting cradle mounted on the chassis and having a projecting end which is engageable with the end of the plant chassis, a support and guide surface provided on the projecting end of the cradle which is engageable with a lifting surface provided on the end of the plant chassis, in order to suspend one end of the plant chassis above the ground, and a slide mounting the cradle on the bogie chassis for relative slidable movement between a lowered position and a raised lifting position. In the lowered position, the end of the plant chassis is standing on the ground adjacent thereto. In the raised lifting position, the end of the plant chassis is lifted off the ground and is supported by the support and guide surface of the lifting cradle.

Abstract: A screening finger assembly having a holder (19) and a set of generally parallel finger tines (16) spaced apart in a row and each mounted in cantilever manner in a respective mounting (20, 22) in the holder (19). Each tine (16) has an outboard end (17), and an inboard end (18) which is firmly clamped in the respective mounting (20, 22). The inboard end (18) of each tine (16) includes a tapered portion. Each mounting includes a mounting bush (20) which is securely mounted in position in the holder (19), and an intermediate load-absorbing sleeve (22) arranged internally of the bush (20) and having an internal surface corresponding in shape to the tapered portion (18) of the tine (16) which it receives. A fastening means (23, 24) moves the tapered portion (18) of the tine (16) axially into firm clamping engagement with the internal surface of the intermediate sleeve (22) to clamp the tine (16) in position.

Abstract: A screening plant having a main frame, a trammel drum mounted on the main frame to be rotatable about a rotational axis at a small angle to the horizontal, and having an input end and an opposite discharge end at a lower end than the input end, screening apertures provided in the wall of the drum, drive means coupled with the drum and operative to rotate the drum while screening takes place, an input hopper mounted on the main frame and arranged to supply bulk material to the input end of the drum, an inclined guide shoot which feeds material from the hopper laterally so as to enter the input end of the drum, and a cantilever type rotatable mounting assembly which rotatably mounts the input end of the drum on the main frame of the plant.

Abstract: A cone crusher is disclosed with a bowl having a concave liner, a head having a mantle and which is capable of carrying out gyratory movement within the bowl so that the concave liner and the mantle define a generally annular crushing space and cooperate to exert a crushing action on crushable material in such space, and a drive train coupled with the head and operative to apply gyratory movement thereto. The drive train includes an upright drive shaft, an eccentric mounted on, and arranged to be driven by the drive shaft. The head is mounted on the eccentric so that the head is driven to carry out gyratory movement within the bowl. A drive motor is coupled with a lower end of the drive shaft to present minimum obstacle to direct downward gravity discharge of crushed material from the crushing space defined between the concave liner and the mantle.

Abstract: A tractor unit/trailer combination which is capable of carrying out suspended transport of a heavy duty piece of equipment, with the equipment being coupled at its forward end to the tractor unit and at its rear end to the trailer, and in such a way that the equipment remains suspended above the ground while at the same time forming an articulated connection between the tractor unit and the trailer. The tractor unit has a fifth wheel coupling to which the forward end of the piece of equipment can be coupled. The trailer has an inclined support ramp on which the rear end of the piece of equipment can be supported. A coupling plate is provided which is able to couple the forward end of the piece of equipment to the fifth wheel coupling. Upon uncoupling of the piece of equipment from the tractor unit and the trailer, when it has reached its destination, the trailer can then be coupled directly to the tractor unit so as to form a tractor unit/combination.

Abstract: There is disclosed an endless conveyor elevator with a foldable support frame, and which has a chassi (3), a tail conveyor section (1) pivotally connected at its tail end (2) to the chassis (3) and pivotally connected at its other end (4) to the lower end of an intermediate conveyor section (5). The upper end (6) of the intermediate conveyor section (5) is pivotally connected to one end of a head conveyor section (7). An actuator (12) is coupled with the conveyor sections to move them between an inoperative folded position, as shown in FIG. 1, to an unfolded rectilinear working position shown in FIG. 2. This movement of the conveyor sections between the inoperative and working positions is achieved by the geometry of the conveyor sections and that of a link member (9) which interconnects the chassis (3) and the head conveyor section (7).
