Carousel Work Platform travels to 39” by a cable extension transducer. The customer’s application required the lift to travel to two stopped positions operated by push button controls wired from the control panel. When first raising the lift, it will stop at 19.5” travel. The up button must be released and re-pressed to continue up to the next travel position of 39”. When lowering the lift does not stop at the 19.5” travel but lowers completely.
