SAMiGUARD

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.

• Easy access - drive is reset in minutes and only the fuse is replaced
• Taper construction gives maximum rigidity with no wear from backlash
• Clamping screws give positive axial location; shear neck cannot be displaced from correct position between flanges
• Equal load sharing with multiple fuses in high torque drives
• Very high capacity within compact dimensions
• Shear necks are standardised and colour coded giving safe, tamper-proof repeatability and spares economy
• "Fail-safe" under all conditions.
• Not affected by changes in temperature or humidity
• Ability to release not dependent on lubrication
