It provides operators with data on the tensions in the chains, and should the loads reach pre-set limits, the system has the facility to decrease/increase tension in the chain, generate alarms to warn operators to take corrective action before any breakdown occurs or stop the conveyor.
“Operators no longer have to worry about chain overloading and potential system failure, which has the additional benefit of providing significant cost savings from both improved operation and increased chain life,” said Adrian Coventry, engineering director, Strainstall. “Also, as it uses our load cells and pins that have many years of proven use in harsh environments, they are can be assured our system will provide long term, hassle-free operation.”
The system uses Strainstall load pins or compressive load cells to measure the tension in the armored face conveyor chain. Specifically designed to operate in extreme temperatures and resistant to high moisture levels, abrasive materials and vibration, both the load pins and load cells are idea for use in the harsh conditions found underground. The load pins are also resistant to the effects of metal fatigue, a condition caused by being subjected to repeated cyclic loads. www.strainstallmarine.com
