product news Monitoring Systems Assist with Moving Overburden and Loading Coal Using strain-sensing transducers placed on the A-frame and boom structures, the system monitors the shovel's health. BMT WBM is set to deliver two new Pulse TerraMetrix RS systems to Teck Resources. Machine health, production and payload measurement will be managed by the Pulse TerraMetrix System on the entire shovel fleet at Teck's Greenhills operation near Elkford, B.C., Canada. This includes one P&H4100; XPB and two P&H4100; XPC machines, one of which is currently being assembled. Following the final implementation of a similar system on a P&H4100; XPB in 2012, Teck staff recognized the benefits of this innovative payload monitoring system together with its interactive server database, allowing personnel to easily analyze health, production and payload data. "Unlike other payload monitoring systems that apply electrical parameter estimation techniques to approximate the payload, the Pulse TerraMetrix RS system employs a loadcell based device and directly measures the inertial and dynamic loads applied to the dipper," said Charles Constancon, director of BMT WBM Canada. "As a result, more accurate payload measurement is main- 56 www.coalage.com tained, even under severe dynamic loading conditions." Configured to communicate with any third party truck dispatch system, the Pulse TerraMetrix RS system can be applied to different models of electric rope shovels including P&H4100; and Cat 7495 machines. Recent developments of the system have included a comprehensive machine health monitoring capability using strain sensing transducers placed on the A-frame and boom structures. These transducers allow the system to track boom jacking and adverse swing events, identify alarm events, and quantify the mechanical damage per swing cycle. Productivity indicators provide meaningful online feedback to the operator including average bucket/truck payload, overall shift production, swing cycle time, and operating and delay times. The system developed for Teck is configured to communicate through the mine wireless mesh to a server located in the mine's administration offices. Data is saved in a SQL database and is accessible through an advanced server analysis program located on the mine's intranet. This enables maintenance, training and production staff to easily access, process and analyze the data on a shift basis, to identify where production shortfalls arise, and where further operator training is required. www.bmt.org/markets/mining/ High Pressure Pumping System RMI's Quinmax S500 features a five piston crankshaft that allows it to pump higher flow rates (340-1,080 l/min) at greater pressure (190-1,000 Bar) with reduced loads on the shaft and bearings for greater periods before service intervals. The range is driven by 300-400 kW motors and feature ram diameters spanning from 50 mm to 80 mm. May 2013
