Caterpillar Introduces New 824K Wheel Dozer for Improved Efficiency
Designing and manufacturing equipment for the mining industry is an art form, and Caterpillar has perfected the process.
Building on the solid performance of predecessor models, Caterpillar Inc. has launched the new Cat® 824K Wheel Dozer, delivering efficient productivity with long-term durability for optimum value. The new wheel dozer features enhancements in safety, serviceability and machine management, including engineering refinements in its power train, operator station and structures.
The 824K equipment boasts a net power rating of 405 horsepower (302kW) with a maximum operating weight of 74,966 pounds. With a six blade configuration ranging in capacity, the 824K is customized for production dozing, stockpile dozing and cleanup work.
The wheel dozer features the Cat C15 ACERT™ engine, a newly designed electronically controlled fuel system that features engine idle shutdown system to conserve fuel by limiting idling time. The shutdown feature also ensures the engine is not stopped until operating temperatures have stabilized.
The Cat C15 ACERT™ engine is equipped with drive train efficiency, fuel economy and travel speeds that are further enhanced with the lock-up clutch in the Cat torque converter, a recently added feature that reduces both drive train power losses and system heat.
According to Caterpillar, “For further drive train efficiency, the smooth-shifting, electronically controlled, 4F/4R Cat power shift transmission can be set by the operator to automatically upshift or downshift based on machine speed. In addition, the Single Clutch Speed Shifting controls allow the 824K to carry momentum through range shifts for high productivity and fuel savings.”
Bigger is always better
The massive design of the 824K Wheel Dozer integrates a full box-section rear frame designed to resist twisting forces and shock loads, which are typically encountered in heavy dozing. Caterpillar has implemented new steering cylinder mounts designed to effectively dissipate steering loads into the frame, and axle mounts for heavy-duty components, adding overall structural integrity. Overall, the purpose-built structure of the 824K results in significant cost savings and sustained optimum performance over the life cycle of the vehicle.

Safety in mind
The new 824K wheel dozer was designed with safety in mind. Caterpillar has integrated the Cat Vital Information System (VIMS™ 3G) which will keep operators informed about machine operating conditions via a graphic display that features a touch-screen interface. In addition, the company has expanded machine monitoring capability with the Cat Product Link™ system to provide event and diagnostic codes. The system also includes operating hours, fuel level and idle time is transmitted to a secure web-based application, VisionLink®, which is then conveyed to machine owners and dealers.
Keeping safety in mind, Caterpillar has included protective accessories to the new 824K dozer. The vehicle features non-skid walkways that are protected with handrails as well as wing-out doors on both sides of the engine compartment, providing easy access to daily service checks. Engine maintenance is simplified with ecology drains to prevent spills along with ground level power service center with electrical disconnect, emergency engine shutdown and stairway light switches.
For such a massive vehicle the 824K is designed with convenience and comfort. The dozer is designed with STIC armrest to fold away for added room as well as Cat Comfort Series air-suspension seats featuring extra thick cushions. The cab, which is isolated-mounted to the frame, is pressurized with filtered air, and the selected temperature is maintained automatically.
The control panel also includes large, backlit switches with LED indicators with simple two-position rocker switch that control the parking brake. Not to be outdone, an optional rearview camera with in-cab monitoring has been added to increase operator awareness.
Net zero benefits the mining industry and the environment
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.”
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.
