Full safety for tandem cranes
This new concept for full safety when cranes are operating in tandem, is an add-on system that can be mounted without any modification in the electric box of the cranes !
A wireless transfer of safety contact and safety control of the travel function with 3 relay configuration, is made by just one master + RF module on each crane. The software provides the safety control of the limit switches (1st and 2nd speed) for travelling and takes into account the anti-collision.
The system has a full duplex bidirectional communication.
Digital contacts for travel direction and tandem information are connected to the inputs.
Through the analogue input we can provide an extra safety option to stop travelling the cranes by controlling the initial distance between the cranes : if this parameter exceeds a tolerance both are stopped !
Easy and fast installation !
