Yaskawa Motoman (Dayton, OH) expanded its line of RM2 ferris wheel-style robotic part positioners. The positioners have two servo-driven trunnion/station axes on opposite sides of a central “sweep” axis. One station is positioned in front of one to four welding robots, while the other station is outside the robot envelope where the operator loads/unloads parts. The 180° sweep axis rotates the stations over/under the central axis between the robot(s) and the operator. Slim-Line positioner models have a 17% smaller width than standard positioners, and are available with 755-kg and 1,255-kg payload capacities. Extra-large-capacity positioners were designed to provide higher payloads and turning diameters in a reduced profile, and feature 1,555-kg and 2,355-kg payload capacities.
