For mine operators, keeping an electric rope shovel in the bank is essential for optimum productivity and profitability.

Recognising this, Caterpillar has introduced the Operator Assist—Enhanced Motion Control system. The software is designed to simplify machine operation, promoting high production while protecting the machine from inadvertent misuse. The new system enhances production by reducing operating faults, such as crowd over-speeds and boom jacks.

The system can yield a number of significant benefits, including more reliable crowd rope replacement schedules, full design life for hoist ropes, reduced wear on crowd brakes, and longer life for hoist gear case components.

It reduces downtime for maintenance and repair by controlling machine motions under certain conditions. This translates to added production and lower cost per ton—with a return on investment typically less than six months.

Five advantages of the Operator Assist – Enhanced Motion Control system:

When developing, the Operator Assist—Enhanced Motion Control system, Caterpillar engineers reviewed the operating habits of numerous operators of all skill levels. Based on this practical information, the new system addresses specific operating situations that could potentially jeopardise both the machine and the production schedule.

Hoist stall prevention: Over-crowding the dipper and excessive loading can stall the dipper and place detrimental forces on hoist gear-case components. The Operator Assist—Enhanced Motion Control system monitors force and optimises crowd/retract commands in relation to hoist speed. Optimising the loading cycle reduces stress and wear on hoist system components.

Boom jack prevention: Current in-service machines can crowd against the bank floor and lift the boom with the dipper handle. This triggers faults that adversely affect cycle times. The Operator Assist—Enhanced Motion Control system aims to prevent boom jacking by automatically adjusting hoist and crowd to maintain proper rope tension. With the new system, the operator will experience fewer digging interruptions.

Crowd impact prevention: A crowd impact occurs when the dipper hits the bank with high inertia resulting in high crowd rope stresses. If the crowd motor continues to apply force in this situation, the crowd ropes are subjected to shock loading. The Operator Assist—Enhanced Motion Control system measures force on the crowd rope and automatically adjusts motor output to avoid shock loading, keeping the dipper in the bank with just the right amount of force. The net result is extended life for crowd ropes.

Crowd over-speed prevention: A crowd over-speed occurs when the commanded speed is exceeded and the brake automatically applies. This action interrupts the digging cycle and causes unnecessary wear on the crowd brake. The Operator Assist—Enhanced Motion Control system provides more braking power to prevent over-speed situations. This feature eliminates the need to de-rate crowd speed in near-vertical handle positions, unburdens the operator and improves crowd brake life.

In-bank swing prevention: When the operator attempts to swing the dipper through the bank, side-loading forces on the dipper can damage shovel components. The Operator Assist—Enhanced Motion Control system can determine dipper engagement and limit swing forces to avoid damage.

Learn how to future proof your business for a zero-carbon world with help from Emitwise and the Oren Marketplace...

How do we get the world to net-zero faster?

Emitwise’s founders, Mauro Cozzi, Eduardo Gómez and Ben Peddie, approached a network of more than 100 of the world's largest enterprises and asked their CEOs, CFOs, and sustainability managers the big question: How do we get the world to net-zero faster? The challenge many shared was the lack of timely and accurate emissions data to enable strategic decisions. Companies often relied on annual audits of their carbon footprint for carbon accounting purposes. However, static yearly results were outdated upon publishing.

Emitwise saves companies an average of 260 working days a year by automating their scope 1, 2 and 3 emissions data. With the added benefits of clean audit trails and auto-populated accounting reports in line with GHG Protocol, all at the click of a button. Their easy to use solution enables businesses to quickly identify the carbon hotspots to target, and the precise real-time data empowers teams to remain agile and respond effectively, making achieving those goals possible.

Unique AI Technology

Emitwise’s unique AI technology empowers businesses to automatically measure, report and reduce their carbon footprint across their operations and supply chain, future-proofing companies for a zero-carbon world. It is the only solution that enables companies to fully automate their carbon accounting across all business units and suppliers, therefore liberating them from the drudgery of collecting and processing emissions data.

By using artificial intelligence to precisely measure emissions in real-time, businesses can identify and tackle carbon hotspots swiftly, enabling them to devise a trackable roadmap to net-zero carbon. At the same time, accurate audit trails and auto-populated annual reports ensure that companies comply with international reporting requirements, and align businesses with global climate targets to mitigate risk across their operations and supply chain. 

The Oren Marketplace

Environmental management, social license to operate, safety, renewable energy to lower emissions and operational efficiency for mining can be supported by a range of digital solutions enabling dynamic operations. To address these issues, Shell and IBM joined forces to create the Oren Marketplace – the first B2B solutions platform for the mining sector. 

With the adoption of many of the digital solutions offered through Oren, mining companies can adapt in real-time to risks or adjust plans ahead of a problem occurring. The goal is a shift towards proactive management as the optimal outcome for all stakeholders – community, shareholders, and employees.

Emitwise was founded with the goal of helping industries across all sectors reduce their carbon footprint. Similarly, Shell aims to become a net-zero emissions energy business by 2050, or sooner, in step with society and its customers. And Oren is focused on offering innovative products and services that can help mining companies track and reduce their emissions. 

“Oren is the starting point for how we help our mining customers to de-carbonise,” explains Carol Chen, Global Lubricants Marketing, Vice President, Shell. “It’s our ambition to work with sectors like mining to help them find their own pathway to net-zero emissions through collaboration. The Oren marketplace offers a great opportunity for collaboration between the miners and technology companies that are joining this digital marketplace.” 

Web Summit

Emitwise will be showcasing its vision for a net-zero future live from Lisbon at this year’s Web Summit. Bringing together the people and companies redefining the global tech industry, the online event welcomes 100,000+ attendees from around the world to hear from more than 800 speakers and view offerings from 2,500 startups covering a vast range of topics from Data Science and Climate Change to AI and Machine Learning. To find out more and book your ticket visit Web Summit. 

Emitwise is one of many solutions providers on the Oren platform seeking to address the pain points and environmental concerns of heavy industries like mining. To discover a range of solutions that can further support your operation’s digital transformation and commitment to sustainability, visit the Oren Marketplace.
