The material conveyor and hopper unit MFS-D/ MFS-SB is designed for continuous material transfer and material storage. The MFS-SB design provides additionally for lateral discharge of material due to the swivel type transfer conveyor belt. The MFS-D / MFS-SB can be operated in conjunction with other units, i.e. material can be transferred from one unit to another to form a material handling system. Furthermore, the MFS-D / MFS-SB is designed to accept material from ballast cleaning machines type RM 900(-RT), RM 95-RT and RM 90 NR or from a material handling power wagon SLSHS-PW (spoil handling power wagon). It must not be used for transport of people.
The MFS-D / MFS-SB is a 2-bogie type vehicle designed in compliance with Railway Group Standard RGS GM/RT 2400, issue 5 and consists of 2-axle bogies, a machine frame with integrated hopper and a transfer conveyor belt. The MFS can be integrated into material handling trains as required, provided it is coupled either to a similar unit positioned in front or a match wagon with a support for the transfer conveyor belt.
The floor of the hopper is designed as conveyor belt enabling to transfer the material to the front end or to store material coming from the rear end of the unit. Furthermore, the material flowing from the hopper conveyor belt onto the transfer conveyor belt on the front end can be discharged to another MFS-SB or a MFS-D unit. The additional feature of the MFS-SB type is the swivel type conveyor belt allowing material to be discharged to the side thus enabling to unload the unit or a complete material handling system. The transfer conveyor belt can be swivelled horizontally up to + 45° providing a loading range of approx. 4 000 mm from track centre to the side. Usually the MFS-SB unit unloads material in depots or sidings to the ground. In case a wagon shall be loaded standing on an adjacent track, a maximum height of side walls of 1850 mm has to be considered.
The continuous material flow allows handling various kinds of materials on the track under treatment, thus not affecting adjacent tracks on multiple lines by this process. The advantage is to handle large quantities of material without the need of additional loading facilities not causing any hindrance to the progress of ballast cleaning activities or track formation rehabilitation work.
