Bradken has launched Bradken SmartRoller™, a digital system that continuously monitors excavator undercarriage roller temperature in real time via remote sensing. By tracking temperature trends as a proxy for wear progression and issuing early alerts, the system allows operators to schedule proactive roller replacement rather than waiting for failure. The approach targets higher excavator uptime, more stable undercarriage performance and lower lifecycle costs for high-hour fleets in abrasive conditions.

MAV2205 shaft–hub locking devices are being engineered specifically for mining conveyor pulleys where high belt tensions and heavily loaded drive or bend drums impose severe bending loads on the pulley shaft, not just torque. By clamping concentrically along the shaft–hub interface, the unit spreads bending stresses more evenly than traditional keyed or welded connections, reducing local stress concentrations that initiate fatigue cracks. For designers and maintenance teams, this supports longer pulley service life, fewer unplanned shutdowns and more predictable performance in high-tension conveyor duty.

Alkane Resources has intersected gold–copper mineralisation about 1km below the former Proprietary open pit at Peak Hill, NSW, in 1651m diamond hole PHD084, which cut altered zones with low-grade mineralisation interpreted as a continuation of the Peak Hill epithermal system. The company is weighing a follow-up deep drilling campaign targeting this down-plunge potential beneath the historic open pit. For geotechnical and mine planners, any future underground concept will hinge on rock mass conditions at >1km depth and interaction with the existing pit wall and backfill.
