A heavy-load option for Sepro Generation IV beam robots reportedly allows them to handle 50% more payload. The Sepro 4050, the largest in the 4000 Series, can carry a 121-lb payload with this option. Other robots in the series available with this option include the 4020, with heavy-load capacity of 22 lb and the 4030, which can be specified to handle up to 44 lb. This new capability means that molders can handle applications that previously might have required a bigger and more costly robot. The 4000 Series robots are designed to serve injection-molding machines as large as 2500 tons.
The beam robots feature standard horizontal stroke lengths up to 118 inches, vertical strokes up to 94 inches, and strip stokes to 51 inches. If the heavy-load option is not needed, they also can be specified with extended vertical and strip stroke lengths. Other features, such as new compact servo wrist-rotation units and digital vacuum-control software, are said to increase user convenience and safety.
