Product Details

The Minova Yielding (MY) Bolt is the next evolution in dynamic ground support, combining immediate frictional resistance with controlled energy absorption to perform where standard bolts fail.

Designed for squeezing, deforming, and dynamic ground, MY Bolt™ delivers consistent reinforcement through every stage of ground movement.

Minova MY Bolt is an easy-to-install point anchor bolt with immediate support by a frictional component. Minova MY Bolt consists of a 47mm Friction bolt outer shell with a high strength 22mm solid bolt, forming the inner core. Minova MY Bolt features a unique expandable anchor with heavy duty wedge working in tandem to provide effective anchorage. MY Bolt features 36 AF heavy duty nut to provide effective preloading, efficient and dependable load transfer to the plate. Minova MY Bolts are designed to support loads over 27t.

Minova products are manufactured to stringent specifications at the state-of-the-art facility.

Product Features

MY Bolt™: instant, controlled support

Controlled Energy Absorption

The yielding mechanism allows the bolt to deform in a controlled manner, dissipating energy from rock movements and seismic events.Prevents sudden breakage and maintains support during dynamic loading

Enhanced Load Transfer

The serrated wedge system ensures positive load transfer into the surrounding rock, maximizing support efficiency. Engages effectively with fractured or weak rock to improve overall stability

Reliable Braking System

Features an industry-leading braking system that prevents the bar's ejection once it reaches its designed load limit

Compatibility with Various Ground Conditions

Effective in both hard rock and weak, squeezing,fractured formations. Can be used in combination with other support systems(mesh, shotcrete, etc,) for enhanced stability

Immediate and Long-Term Support

Provides instant frictional and mechanical anchorage upon installation. Continues to perform effectively as the ground shifts over time
