Niscon's new Raynok Concerto series of variable speed concert hoists has been engineered with the support and assistance of R&M Materials Handling using a Stagemaker Concert Hoist body and adding a rotary limit switch, load cell and three encoders. The two sets of safety limits act to prevent accidental over-travel. The rotary switch is monitored for rotation using an encoder which also functions as the backup encoder. The third encoder is attached to the load wheel to ensure the chain has traveled to its exact position. The values from each encoder are constantly compared against the others for errors.
