The MFS 3/150 material conveyor and hopper units are of standard vehicle design and consist of three storage units each. Each storage unit has two 2-axle bogies, a storage hopper with floor conveyor belt and transfer conveyor belt. Drive engine, hydraulic system and ancillary units are positioned on the underside of the centre unit. The operator’s stand is located next to the transfer/discharge belt of the front storage unit. An automated loading system moves the floor conveyor belt forward in step-by-step motion so as to ensure that the hopper is filled continuously and uniformly, thus enabling automated loading and unloading of whole MFS consists.
