The rotating portal crane is essential to the paper making process, but is often overlooked. The rotating portal cranes operate in extremely hazardous environments, lifting thousands of pounds of logs. Their function is to transport incoming logs from truckloads by grasping and stacking them in the woodyard for the next stage of operation.
Any disruption to the operation of a rotating portal crane stops the entire flow of the paper making process – a long series of mechanical and chemical processing that turns wood into paper.
This is a huge problem. Why?
A crane failure can mean as much as 10 hours of downtime. This could cost between $60,000-$150,000, when considering the cost of repairs, labor and lost production.
SO WHY DO
WOODYARD CRANE FAILURES
The motion of the rotating portal crane is intermittent, which makes it challenging to detect and diagnose problems. It is nearly impossible to get to the equipment during operations without putting your life at risk, so traditional route-based measurement is out of the question for accurate machine health status updates.
The motor and gearbox that drive the crane is vulnerable to failures such as bearing degradation, oil contamination, cracked gear tooth, etc.
The motor on the hoist enables the crane to lift and lower the load. The motor is prone to failures such as bearing degradation and mechanical wear.
The trolley motor allows for a two way axial movement along the rail.
HOW CAN LUMBER YARDS
GAIN THE UPPER HAND?
The KCF Technologies IoT Hub uniquely addresses the needs of Wood Yard Cranes.
It comes packaged with up to 7 wired sensors that continuously monitor key inflection points in the conveyance system and wirelessly transfer data to a Base Station. Data acquisition is triggered through connection to the system controls, enabling synchronized measurements with known operation points.
Consistent measurements are obtained for more accurate monitoring, diagnosis, and action, so you can validate when maintenance is performed correctly. Or when it’s not.
Variations in cycle time are correlated with measurements of the IoT Hub to identify issues and enable proactive solutions. Custom dashboard integrations mean your real-time data is accessible 24/7.
Now the Operations and Maintenance teams can monitor machine health, securely and remotely, at any time.
In the Heart of Happy Valley.
