It is mainly reduced by the rotary cylinder expansion, several parts slide base, axial hydraulic cylinders, cylinder head reel, reel drive mechanism.
1. Dcarrying heavy weight. The aircraft is a single-reel cantilevered unwinding machine, can carry 15 tons of coil material;
2. easy feeding operation, stable and reliable operation. When the material on a single reel cantilevered unwinding machine, when the roll feed vehicles in place, until the clamping cylinder retracting clamping pressure, then the material even if the work is completed;
3. unwinding, feeding at the same time, rapid rotation when changing volume, saving on feeding time, save Looper reserves.
