Queins & Co, Germany, has supplied two heavy-duty caterpillar capstans to a Chinese customer, both laid out for a pulling force of 120 kN (12 tons) each. 4-belt caterpillar capstans for offshore cables/umbilicals

Bühler Kaltwalztechnik and Maschinenfabrik Niehoff have presented a production line for manufacturing PV-Ribbon made of copper. Ribbon is rolled by the mill from round copper wire and is tuned by in-line process by induction annealer to the desired mechanical properties. Dimensions that can be handled are 1 to 7mm width and 0.03 to 0.7mm thickness. The yield strength (Rp 0.2) of the final ribbon is ≤ 80Mpa, and the ultimate strain is > 25%. the production line is 1,000m/min, and this applies to the rolling process as well as to the integrated annealing process. For example, an output capacity of 1,500t/pa can be achieved for a solar strip with the dimensions 5.0 x 0.1mm. Bühler Würz Kaltwalztechnik is a manufacturer of cold rolling mills for steel and non-ferrous alloys with long-time tradition and extensive experience in rolling technology for different applications. Together with its partners, Niehoff develops production systems that address all of the needs and preferences of wire and cable manufacturers. are incorporated into the production systems, reflecting the latest advances in technology.
