Runma 1500-3000 Series Large Size three axis full servo traversing robot arm is applicable to all types of horizontal injection machine ranging from 600 to 3000T for products take-out. Vertical arm is telescopic type, with product arm, for two plate mold products take out. Crosswise type adopts open without frame design, X-, Y-, Z-axis are all driven by AC servo motor, also, B and C axis can be added; Meanwhile, it can stack up at any points at X, Y, Z directions, and cut the runner by scissors driven and inset or embed the accessory by the cylinder.
