One method of protecting machinery from overload is a simple shear pin. However, the conventional round shear pin has its drawbacks with the removal of the broken halves and the necessary clearance for fitting which causes pin fatigue, fretting and uncertainty in load sharing between pins. The replacement of the pin can also be an issue with incorrect pins being refitted.
The SAMiGUARD is designed to overcome all these problems and also meet the increasing demands for safety and minimum downtime required by today's process plants. Based upon a tapered pin (fuse), this overload system is a completely new concept in shear pin protection.
