The regular length of Drag chain test machine is 1.5 meters,and this one reaches to 5 meters long,which is customized for a Russia client.
Coincidentally, my Italy customer also needs this length,and came to our plant to check the real machine wth his colleague in China before delivery.
They visited us in October,and when back to Italy,we confirmed the technical requirments and purhcase order in the beginning of November.
