Tower Crane

Klug has designed a complete range of safety systems for tower cranes consisting of trolley radius sensor, trolley height sensor, load pin or dynamometer for load sensor, optional wind speed sensor also. Multi turn encoders are used for the trolley radius and height sensing. Alphanumeric digital display provides the real time load on hook and safe working load for the tower crane.
