Maximizing Shaker Table Reliability with THU and ERM Locknuts
Shaker tables in mining operations are prone to downtime due to loosened screens under extreme shock and vibration. J.Lanfranco THU and ERM locknuts provide high repeatable locking, integrated washer support, and multiple install/removal cycles to keep plants running efficiently.
Eliminating the Bottleneck of Shaker Table Failures
The Challenge: Equipment Failures Kill Operations
Shaker tables in the mining industry operate under extreme conditions: intense shock, vibration, and impact. Loosened screens on these machines can halt production entirely, creating a major operational bottleneck.
Unplanned shutdowns and changeouts have serious consequences:
- Reduced plant throughput
- Lost profit
- Increased labor costs
- Higher warranty costs for screen OEMs if minimum run cycles are not met
For mining operators, unreliable fasteners translate directly into lost revenue and operational disruption.
The Operational Impact: Downtime and Cost Escalation
Before switching to high-performance locknuts, many plants faced repeated interruptions due to fastener failures. Screen assemblies had to be frequently inspected, replaced, or re-torqued, reducing operational efficiency and straining maintenance teams.
This created a persistent bottleneck: no matter how efficient other processes were, production remained limited by fastener reliability.
Defining a Practical Objective & Installation of THU and ERM Locknuts
To address the problem, J.Lanfranco recommended THU and ERM locknuts as a reliable solution.
- Gr.8 ERM 3/4 UNC nuts delivered up to 10 installation on/off cycles, providing high repeatable locking.
- Integrated washers were capable of withstanding 10,000 lbs of force, ensuring screen assemblies remain secure under extreme vibration.
- Locknuts simplified changeouts and installation while maintaining precise clamp force.
The goal: eliminate fastener-related bottlenecks, maximize throughput, and reduce unplanned shutdowns.
Proven Results: Maximized Throughput and Reduced Shutdowns
After installing J.Lanfranco THU and ERM locknuts:
- Shaker table downtime was significantly reduced
- Maintenance labor was lowered
- Screen assemblies remained secure under extreme operating conditions
- Plant throughput improved and operational bottlenecks were eliminated
Reliable locknuts ensured that fasteners no longer dictated production efficiency, protecting both revenue and OEM warranty commitments.
