4.2.3. Applicable coil width 950mm
4.2.4. Winch speed 160r/min
4.2.5. Tension form Mechanical friction
4.2.6. Winch motor power 55KW（AC）
4.2.7. Structure composition: the main part of the bow strander is composed of the stranding bow, the cradle frame of the coil, the bracket, the base, the transmission system, the filling frame, etc. the overall design structure is reasonable and beautiful.
4.2.8. Transmission system: the winch cage is driven by 45KW variable frequency motor, the transmission system is driven by the transmission shaft through the toothed belt, and each cradle is driven by two toothed belts, so the winch itself does not bear torsion.
4.2.9. Cradle frame: both ends of the cradle are supported by bearings, and the cradle adopts end shaft type manual clamping reel with mechanical locking mechanism to prevent the reel from throwing out.
4.2.10. The cradle frame of the main engine is made of CNC laser cutting, integral welding, aging treatment by annealing furnace and integral processing by large machine tool, with high rigidity and high operation precision. Each basket is equipped with a cable tray bracket to provide protection for the wire materials in the cable tray.
4.2.11. The setting out tension is provided by mechanical friction, and the tension is adjusted manually.
4.2.12. The winch is made of special steel, and each pair of winch is tested for static balance.
4.2.13. Base: it is made of high-quality rectangular square tube and steel plate by welding and processed by large gantry milling machine. The whole base has high levelness and ensures the stability of operation.
4.2.14. Braking system: the whole machine is braked by plane air brake, and multiple groups of air brake act at the same time, with high braking efficiency.
4.2.15. Shield: the main engine adopts fully enclosed box type safety shield, and the opening mode is manual sliding door type. The protective cover is equipped with multiple sets of working lights. The protective cover is interlocked with the electrical equipment of the unit. The unit can be started when the protective cover is completely closed
