Cable shovel payload estimation using a strain transducer

点击翻译按钮获取中文摘要

Cable shovels are extensively used in mining equipment for the extraction of minerals and precious metals. An important physical variable that has to be continuously monitored is the weight of the payload inside the Cable Shovel dipper with maximum capacities reaching 120 tonnes per scoop carried by massive haul trucks with capacities of about 400 tonnes. Overloading these mining machines can reduce their engine and tire life, cause fatigue, and result in early failure, which lead to excessive maintenance costs for the mining industry. The proposed Engage activity investigates the feasibility of monitoring the payload inside a cable shovel dipper by analyzing the cable shovel bail strain. The proposed activity will investigate determining the placement of strain sensors and how the sensory system can be made robust in a harsh mining environment which is subject to dust, vibration, and temperature variations.
