Understanding the Purpose and Essentials of Gauges and Switches in Big Rigs
Diving into the world of big rigs, with their plethora of gauges and switches, one may wonder about their true necessity and functionality. Are these features just modern gimmicks, or do they serve a specific and essential purpose? In this article, we explore the importance of these components, highlighting both required and optional gauges and switches, and the role they play in big rig operations.
Why So Many Gauges and Switches?
It is a common industry practice for manufacturers to adorn dashboards with numerous gauges and switches, often numbering in the double digits. This is not just to make the truck appear more sophisticated and justify its high cost. Instead, it serves a practical purpose: providing crucial information for both the vehicle's proper functioning and the driver's safety and efficiency.
The Functionality of Gauges and Switches
Take, for instance, the Western Star rig. Its 19 gauges and 26 switches each have specific purposes, including monitoring engine oil temperature and pressure, air inlet filter blockages, exhaust gas temperature, and more. These features ensure that every system in the truck is functioning correctly and any potential issues can be quickly identified. Trucks like the Scania I drive today have moved towards digital displays, which, while simplified, can still bring up multiple warnings and readings.
Essential Gauges and Requirements
While many gauges and switches are regarded as purely optional, there are a few that are absolutely necessary. These include air pressure, fuel, and coolant temperature gauges, which are required by the DOT. Additionally, gauges for diesel exhaust fluid (ADBlue/DEF) levels are crucial, as an empty tank can significantly reduce engine performance and vehicle safety.
Driver Convenience and Specialized Trucks
Some gauges serve to enhance the driver's experience and efficiency. For example, a gauge indicating the applied pressure to the drive axle suspension can be a significant time-saver, as it provides a quick way to determine the truck's load without the need for a scale. This feature is particularly useful with companies like Werner, where such a gauge has been a valuable asset.
Trucks Hauling Extremely Heavy Loads
For trucks hauling extremely heavy loads, specialized gauges become essential. These trucks often have multi-axle trailers, requiring detailed monitoring of various components to ensure safety and efficiency. In such cases, gauges for engine oil pressure, transmitted temperature, and brake pressure provide valuable information that can prevent failures and costly breakdowns.
Conclusion
In summary, while some gauges and switches in big rigs may appear as mere trinkets, they play a critical role in the truck's operation. Essential gauges such as air pressure, fuel, coolant temperature, and specialized gauges for extremely heavy loads ensure that the truck runs safely and efficiently. The driver, therefore, benefits from having easy access to critical information, enhancing both the vehicle's reliability and the driver's peace of mind.
