Safety Devices

Safety devices protect all the items in a kinematic chain, allowing the line to work at a pre-set maximum level.

In the event of a catastrophically high torque, the device interrupts the torque flow in the driveline, avoiding costly damage and production shutdown.

MAINA can supply different safety devices for incorporation between two flanges:

  • with shear pins, featuring a calibrated groove and an inner hole, the diameter of which affects the release torque;
  • with a breaking spacer, also featuring a calibrated groove in the outer diameter of the pipe;
  • with BIBBIGARD® modules;
  • and, as a result of recent in-house studies, the HYDRO-SAFE® device, a combined hydraulic and mechanical unit.
