ZP7000S – STACKER (Z 7000-90) - NOEN, a.s.

General description

The Z7000-90 stacker is used to stack crushed overburden to a dump.
The stacker consists of a substructure (steel structure connecting three crawler twins of the undercarriage). The slewing superstructure with the tower and the counterweight boom with a counterweight are mounted on the substructure. A discharge boom equipped with a belt conveyor is hinged on the superstructure.

A hinge joint of the connecting bridge is realized at the superstructure level, in suspension of the counterweight boom. This steel structure is supported at another end with a supporting car. The connecting bridge is equipped with a belt conveyor with a charging hopper at the lower end. Material from the preceding technology (e.g. long-distance belt conveyors) is received at this place and further conveyed to a conveyor of the discharge boom. The supporting car consists of a crawler undercarriage, a small substructure and a swivel plate. The connecting bridge is just mounted on this plate.

– The slewing range of the superstructure against the substructure is realized by electromechanical drives.
– Tilting of the discharge boom is realized by means of a hoist and a pair of electromechanical cable winches.
