Best Display for Mining Machinery: What OEMs Should Consider
Mining machinery operates in some of the most demanding industrial environments. Heavy dust, continuous vibration, extreme temperatures, and long operating hours place significant stress on every electronic component installed on the machine.
Among these components, the operator display plays a critical role. It is no longer just a screen for showing basic machine information. In modern mining equipment, the display often serves as the central human-machine interface (HMI), connecting multiple control systems and providing real-time operational feedback.
For OEM manufacturers designing mining machinery, selecting the right display requires careful consideration of several technical factors.
1.Why Mining Machinery Requires Specialized Displays
Displays used in mining equipment must operate reliably in conditions that are far more demanding than typical industrial environments.
Common challenges include:
①High levels of dust and debris
②Continuous mechanical vibration
③Large temperature fluctuations
④Strong sunlight exposure
⑤Long operating cycles
Because the display serves as the main interaction point between the operator and the machine, reliability is essential. Any malfunction in the display can affect machine diagnostics, monitoring functions, and operator safety.
For this reason, displays used in mining machinery are typically designed specifically for mobile equipment and heavy-duty industrial applications.
2.Rugged Mechanical Design
Mining equipment generates constant vibration during operation. Excavators, drilling rigs, and mining trucks all produce mechanical shock loads that can quickly damage poorly designed electronics.
Industrial displays used in these environments usually feature:
①Aluminum alloy housings
②Reinforced mounting structures
③Vibration-resistant internal components
Aluminum housings not only improve structural durability but also help dissipate heat during long operating periods.
A well-designed mechanical structure allows the display to maintain stable performance even when the machine operates continuously in harsh conditions.
3.Wide Operating Voltage Range
Electrical systems in heavy machinery often experience voltage fluctuations, especially during engine start-up or under heavy load.
To ensure stable operation, industrial displays commonly support a wide operating voltage range, typically: 8–32V DC
This voltage range allows the display to operate reliably in different types of mining equipment, including:
①Excavators
②Mining haul trucks
③Drilling machines
④Crushing equipment
Wide voltage compatibility also simplifies system integration for OEM manufacturers.
4.High Brightness and Sunlight Readability
Mining equipment often operates outdoors under strong sunlight. Displays designed only for indoor environments may become difficult to read in these conditions.
Industrial displays used in mining machinery typically provide:
①High brightness levels (≥600 cd/m²)
②Anti-glare display surfaces
③High contrast ratios
These features ensure that operators can clearly read machine information, alarms, and camera feeds even under direct sunlight.
Good sunlight readability is especially important in open-pit mining environments where sunlight exposure is unavoidable.
5.CAN Communication Capability
Modern mining equipment integrates multiple electronic control systems. Engine control units, hydraulic systems, safety modules, and sensors all rely on reliable communication networks.
The most widely used communication protocol in mobile machinery is the CAN bus.
A mining machinery display should ideally support:
①CAN 2.0A/B communication
②Multiple CAN channels
③Stable real-time data exchange
Multi-channel CAN capability allows the display to communicate with several machine subsystems simultaneously.
For example, a 7-inch CAN bus display designed for mobile machinery can support multiple CAN interfaces together with programmable I/O resources, making it suitable for complex equipment control architectures.
6.Video Integration for Safety Monitoring
Camera systems are increasingly used in mining equipment to improve operator safety. Large machines often have significant blind spots, making visual monitoring essential.
Industrial displays can serve as the central interface for these camera systems.
Typical applications include:
①Rear-view monitoring
②Blind spot detection
③Equipment operation monitoring
④Surround safety observation
Many modern industrial displays support multiple AHD or HD camera inputs, allowing operators to switch between camera views directly on the screen.
For instance, a 10.1-inch industrial display with multi-channel video input capability can integrate several camera feeds, helping operators monitor equipment surroundings more effectively.
7.Environmental Protection Level
Environmental protection is an important consideration when selecting displays for mining machinery.
However, the required protection level depends largely on the installation location.
For displays installed inside the operator cabin, IP65 front protection is generally sufficient. This protection level ensures resistance against:
①Dust
②Water splashes
③Industrial contaminants within the cabin
Displays installed in fully exposed outdoor positions may require higher protection levels. However, in most cabin-mounted applications, IP65 provides a practical balance between durability and cost.
8.Touch Technology in Industrial Equipment
Touchscreen interfaces have become standard in modern mobile machinery.
Two main technologies are commonly used:
Capacitive Touch Screens
Advantages include:
①Clear display quality
②Smooth touch response
③Multi-touch capability
④Modern user interface design
Industrial capacitive screens can operate with conductive industrial gloves, which are commonly used in heavy equipment environments.
Resistive Touch Screens
Resistive touch screens can operate with almost any glove type or stylus, but they typically provide lower visual clarity and slower interaction compared to capacitive technology.
As industrial interfaces continue to evolve, capacitive touchscreens are increasingly adopted in modern mobile machinery displays.
9.Software Flexibility and Development Environment
Mining equipment manufacturers often require customized user interfaces tailored to specific machine functions.
Displays that support flexible software development environments make it easier for OEM engineers to implement these requirements.
Typical development environments include:
①CoDeSys 3.5
②Custom HMI development tools
③Integration with machine control systems
These platforms allow engineers to design graphical interfaces, integrate machine data, and implement advanced control logic directly within the display.
10.Typical Applications in Mining Machinery
Industrial displays are widely used across different types of mining equipment.
Typical applications include:
①Hydraulic excavators
②Mining haul trucks
③Underground drilling machines
④Crushing and screening equipment
⑤Material handling systems
In these machines, the display acts as the central interface through which operators monitor machine status, adjust parameters, and observe camera feeds.
For larger control panels or machines that require more screen space for monitoring multiple systems simultaneously, a large-screen industrial HMI can provide a more comprehensive view of machine data and camera information.
Conclusion
Selecting the best display for mining machinery involves evaluating several important technical factors rather than focusing on a single specification.
OEM manufacturers typically consider:
①Mechanical durability
②CAN communication capability
③Video monitoring integration
④Environmental protection level
⑤Software flexibility
A well-designed industrial display should integrate seamlessly with machine control systems while providing reliable operation under demanding working conditions.
By carefully balancing these factors, equipment manufacturers can create operator interfaces that improve machine efficiency, enhance operational safety, and support long-term reliability in mining applications.
