Crane Limit Switch Blue can be widely used in construction, port, mining and other industries of lifting, transmission machinery space three coordinate control and limit, Crane Limit Switch Blue by high precision large transmission ratio reducer and its output shaft synchronous mechanical memory control mechanism, sensor composition, Because the WTAU series limit switch has the characteristics of small volume, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation, use and adjustment in construction machinery should be extremely extensive.
Working principle
The displacement signal of crane limit switch and controlled mechanism synchronization is connected with the input shaft of the limit after the external pulley speed change, and is converted into the angular displacement signal of the output shaft by the reducer speed change.
