• Less cribbing needed in tailgates, reduces mine cost, and increases ventilation

B-Rigid Truss

Widely used and user-friendly truss system especially in extremely adverse conditions such as:
• Extremely laminated conditions
• Highly fractured materials at various anchorage horizons
• Conditions that require higher stiffness with minimal roof movement
• Low profile ensures maximum floor to roof clearance
• Requires no additional tensioning devices
• Standard channels and cable bolts are used
• Short learning curve
