Also new from ChainMaster is a manual controller for up to 48 chain hoists. With the remote control, which is equipped with a 5.7" touch-screen, it is possible to program runs as well as display individual positions and loads. It will also be possible to effect a group shutdown in the event of the synchronicity tolerance being exceeded, the target position being overshot, the direction of rotation being incorrect, or overload or slack chain conditions occurring. Compatibility with the computerized controllers for larger systems is also guaranteed.
Finally, ChainMaster presents an update of its successful VarioLift series, launched earlier this year. The device offers maximum precision and reproducibility in the positioning of chain hoists, and is based on an integrated vector-controlled frequency converter, supplied by a high impulse incremental encoder. The VarioLift operates with a positional accuracy of 0.2 millimetres, say ChainMaster.
