 Do you know the health of your infrastructure? 

 Tokbo senses bolted connections, provides remote predictive monitoring, enables a digital service. 

The TOKBO system can be applied to both existing and newly built structures and requires 4 steps: installing the sensors on the threaded joints, connecting the gateway, setting up the system, switching on the network and monitoring.


  • Continuous monitoring

  • Active safety system

  • Plug&play solution, simple installation

  • Customizable platform

  • Cost optimization of predictive maintenance





From a connected and smart network to a digital platform enabling predictive operation services.

The system is composed of a network of sensorized structural bolts that allows the detection and monitoring of clamping force, vibration, temperature and inclination.

These bolts are connected to each other via gateways.

Tokbo has developed a proprietary solution that allows you to digitize threaded joints by remotely and continuously monitoring the status of the joint with force data and accelerometric status.


Wired version

Ideal for structures where power is present and for a considerable number of nodes to be monitored (large structures such as bridges, railway tracks, etc.) while ensuring service continuity and the management of a large amount of data.
This type of solution also allows you to activate alert messages in real time.

  • Up to 250 sensors

  • 220V power supply

  • 4G communication


Mild Wireless Version

Ideal for structures that are not covered by the electricity network or for structures with reduced accessibility. The mild wireless solution is able to guarantee monitoring of the most critical nodes thanks to the battery pack powered by a solar panel. This type of solution allows you to activate alert messages with a fixed frequency.

  • Powered by solar panels and battery pack

  • Up to 12 sensors

  • 4G communication

  • The platform relies on the cloud which collects the following data:

    • Stress state of the joint

    • Temperature

    • Oscillatory and accelerometric state of the junction

    • Inclinometer state of the sensorized bolt

  • Users can collect data through:

    • Time windows

    • Hierarchy

    • Macrogroups of components

  • Ability to view history and real-time data

  • Alarm notification system

  • Multi-tenant platform

What is the service

  • Continuous tension control of the joint by identifying unscrewing phenomena

  • Temperature detection

  • Oscillatory and accelerometric state of the junction

  • Inclinometric state of the sensorized bolt

  • Alarm system when critical thresholds are exceeded


With the continuous remote monitoring of the structure, costs and times of predictive maintenance can be optimized, guaranteeing support for operations.
