BMT to Supply New Payload Monitoring System to Teck

Canada-based Teck Resources has selected BMT WBM for a new project. According to the terms of the project, BMT will supply Pulse TerraMetrix RS system to Teck.

Teck will equip its Greenhills Operation (GHO), located near Elkford in the southeastern part of British Columbia, with this new system to handle the machine health, payload and production measurement of Shovel 30 (P&H4100). BMT has closely worked with the employees at GHO in order to create and refine the new system to deal with the accuracy problems related to shovel-based payload monitoring systems.

According to BMT WBM Canada’s Director, Charles Constancon, the TerraMetrix RS system uses a load cell-based device and measures the dynamic and inertial loads applied to the dipper, in contrast to other payload monitoring systems that apply electrical parameter calculation methods for payload approximation. Therefore, payload measurement is maintained more precisely even under strict dynamic loading conditions.

This new system is configured in such a way that it can communicate with all third-party truck dispatch systems and can also be applied to various electric rope shovel models, which include CAT 7495 and P&H4100.

The Pulse TerraMetrix RS system has been recently added with a complete machine health monitoring capacity utilizing strain sensing transducers, positioned on the boom and A-frame structures. This system with the help of these transducers is capable of tracking adverse swing and boom jacking events, locating alarm events and measuring the mechanical damage for every swing cycle.

The operator gets significant online feedback from productivity indicators, wherein the feedback includes overall shift production, average truck/bucket payload, delay and operating times, and swing cycle time

The system, developed particularly for Teck, is designed to communicate to a server through the mine wireless mesh. The server is based in the administration offices of the mine. A SQL database saves the data, which can be accessed by means of an advanced server analysis program. This facilitates employees, involved in production, maintenance and training, to process and examine the data and find where additional operator training is needed and where production shortfalls occur.
