RCV slewing mechanism adopts stepless speed control with advanced electrical adjustment and eddy brake, with no inertial, running stably and locating more precisely. It is composed of Y or YD series multi-speed motor, speed reducer and driving gear. RVF series are variable frequency control slewing mechanism, with the same structure as RCV. It has the advantage of high working efficiency, long service life, low maintenance cost, comfortable operation and so on.
