New ‘Segnut F.I.R.S.T’ Prototype Eliminates Pinch Point Hazards, Improves Maintenance Productivity

Segnut FIRST - Pinch Point Hazard Reduction System

Segnut has been provided with assistance from the Advanced Manufacturing Growth Centre Ltd to develop the game-chaning Segnut F.I.R.S.T system which eliminates the pinch point or crush risk posed by nut-runner reaction arms. We’re working with BHP to bring this great concept to life.

The system, known as Segnut F.I.R.S.T (Fully Internalised Reaction Socket Technology), has been developed by Segnut in response to the ongoing risk faced by mobile plant maintenance teams when installing and removing nuts from Ground Engaging Tools (GETs) such as dozer blades.

GETs are subject to high levels of vibration, impact, erosion, and damage because of the nature of work being performed. This means the retaining bolts must be applied with high torques that cannot be achieved by manual means. Typically, this is done using powered torque multipliers (“nutrunners”) or impact wrenches (“rattle guns”) Each comes with its own set of safety hazards. Removing the nuts, often requires “gas-axing” (oxy-acetylene cutting) – again with its own safety and equipment damage challenges.

Segnut F.I.R.S.T is a unique combination of the Segnut fastener technology with a modified Plow Bolt which incorporates a “Reaction Bit”. This allows both the installation and removal torques to be internally reacted within the F.I.R.S.T Socket – pairing with existing technology of powered torque multipliers and wrenches.

If you would like assistance to explore the potential for Segnut F.I.R.S.T as a pinch point prevention strategy, or as a way to improve maintenance productivity, please contact Segnut. If you would like to receive early notification of future publications, please sign up for our Newsletter now
