Shears workflow
Scrap is filled into the hopper by means of a grab loader. Due to the horizontal movement of the holder and the scrap’s dead weight, it falls to the bottom of the loading chamber and into the cutting space. After having been compressed on the front wall, the scrap is cut by the horizontally-moving tool-holding slide via the blades on the front wall. While the tool-holding slide is moving horizontally, the processed material is pushed out via the blades on the container’s front wall. While returning to the rear position, the loaded scrap moves under its own weight into the shears’ interior.

Processing scrap
Compared to standard stationary shears, ZDAS container shears offer an original method of cutting by means of a horizontal movable tool-holding slide. This slide is located on the lower part of the loading chamber.
The shears can be remotely operated.
Like standard large-volume containers, these shears can also be lifted and moved by a hooklift truck.
The shears can be delivered with both diesel and electric engines. In addition to the standard version, Tropic and Arctic variants are also available.
The CNS 400 K shears are offered with the following options:
Top hopper
Guide for loading long pieces – internal hopper
CNS 400 K – diesel
Combination of diesel engine and pump for the shears drive
Due to the effective diesel-hydraulic power pack, low consumption is achieved – as low as 1.2 l per one ton of scrap (depending on the type of scrap)
A control system from reputable suppliers, which displays error messages, is installed in the machine’s distribution box
Hydraulic components with extended service lives are supplied by well-respected global manufacturers
The standard water-cooled diesel engine guarantees trouble-free operation even at extreme temperatures of –20 °C to 35 °C
CNS 400 K-E – elektro
Combination of electric engine and pump for the shears drive
For scrap yards with access to electricity, ZDAS offers a variant of the shears with an electric engine
Control system including error messages is installed inside the machine’s distribution box and is supplied by well-respected manufacturers
Lower costs for one ton of processed scrap
Quiet operation
Minimum amount of engine maintenance
Longer service life of the pumps when working at lower speeds
Maintenance downtime is reduced
Both diesel and electric versions can be supplied in Tropic (up to +45°C) or Arctic (up to –30 °C) variants
