Ball Washer

OPTI-Load SYSTEM is intended to optimize the performance of the rock bolt in its critical area, i.e. the interface between inflation bushing and face plate. The system is formed by a patent protected Ball Washer and an Omega Domed Face Plate of appropriate geometry and steel grade. Both the ball washer and face plate are mounted on a regular OMEGA-BOLT^® 120 just before installation.

Fields of Application

Systematic reinforcement of underground excavations
Temporary ground control
Critical underground areas

Main benefits

Enhances structural integrity by delivering higher loading capacity while absorbing larger deformations
Improves safety, with face plate flattening signalling when the bolt is under a heavy load
Ensures reliable operation by compensating for misalignment between the bolt and face plate at angles up to 10 degrees without degradation in load capacity
