Explanation of the short playing time:
The entire line of Cross Wrap bale opener type BO 4000 was installed
at a municipal waste incineration plant in 2015. The background to the
installation of the plant was that in the event of an operational
malfunction or maintenance of the incinerator, the municipal waste can
continue to be received, pressed, wrapped and stored until the
malfunction is eliminated. Then the bales should all be reopened and
the waste fed into the normal incineration process.
This worst-case scenario never happened. The plant was set up, run in
and has never been used in regular operation afterwards. Only during
the commissioning and running-in of the entire plant in 2015, 674
bales were opened on three days. The plant is in a very good,
immediately ready for use. Due to renovation work in the incineration
plant, the installation area of the bale opener was required. As a
result, the complete line is for sale.
Brief description of the bale opening process:
The pressed bales are placed on the feed conveyor belt from the side
or from behind by means of a forklift truck. To open, the bales with
the wire or twine tying must run horizontally to the conveyor belt,
otherwise the bales must be rotated by 90° beforehand. The opening
conveyor belt brings one bale at a time in front of the cutting unit.
The grippers hold the wires or the yarn strapping. The rotating blade
cuts the bale lengthwise. The gripper then returns to the starting
position. The open bale is now conveyed via the conveyor belt to the
discharge chute and then falls onto the downstream conveyor system.
Remarks:
New price of the complete system 296,000 €. The documentation
(operating instructions, CE declaration, electrical/hydraulic circuit
diagram) is completely available. The system has been dismantled into
freightable units, stored and is available for inspection and loading
at short notice. We assume no liability for the technical information
or any errors.
