The stockyard stacker SZ 5.1-51 is used to stack iron ore to the homogenization stockyard. The stacker is above all intended for homogenization stockyard stacking using the “windrow” method but can be also easily used for stacking by means of other methods.
The stacker consists of a substructure (steel structure connecting individual beams of the rail undercarriage). Interconnection with a leading part (steel structure on the rail undercarriage, carrying the leading part of the stockyard conveyor and other equipment of the machine) is also realized at the level of the substructure. The slewing central structure is mounted on the substructure. The hinged superstructure, which consists of the king tower with a counterweight and a discharge boom with a belt conveyor, is framed in the slewing central structure.
– The slewing range of the superstructure against the substructure is realized by electromechanical drives.
– Tilting of the superstructure against the central structure is realized by a pair of hydraulic cylinders.
The stacker is placed on the rail undercarriage. Length of travelling track (rails), thereby length of stockyard as well, is only limited by size of a cable drum for power supply of the machine.
