Temperature Management For Your Fleet
At DBA Silencing, we have a unique competitive advantage; we’ve developed an industry-leading thermal management technology that reduces truck fires. As outlined in our blog post “DBA & Mining Haul Truck Safety“, we encase our exhaust components in rigid composite shells that reduce the surface temperatures of our exhaust systems below the flash point for mining truck operating fluids such as oil. Many of the customers that have been ordering from DBA for decades originally started employing our parts because they wanted to reduce truck fires on their sites.
Thankfully, modern mining trucks are far less likely than their predecessors to be lost in a conflagration. Many mining trucks, however, continue to struggle with thermal loads. While it may not be as serious as a full-on blaze, overheating does pose a substantial threat to the mobile assets in a mining fleet. When heavy equipment begins overheating under load, the consequences can be severe. Excessive heat can lead to reduced engine performance, premature deterioration of parts, costly repairs, unexpected shutdowns, and decreased production. In mining operations where uptime is directly correlated with profitability, mining truck overheating can quickly become a major concern.
In this article, we’ll look at some common sources of mining truck overheating issues. We will explore, in addition, the warning signs operators should watch for, as well as the ways DBA Silencing parts and systems can be useful when vehicles are gettin’ hot ‘n’ bothered.
Reasons For Overheating
Most heavy equipment naturally generates more heat when operating at capacity. As engine activity increases, cooling systems must work significantly harder to maintain safe operating temperatures. On mine sites, operating systems are also contending with dust, debris, vibration, and rough terrain. For those who are interested, we explore these challenges further in our blog post “Heavy-Duty Parts For Extreme Environments“.
One of the most common causes of mining truck overheating is restricted airflow from dust accumulation. Dust often accumulates on radiators, air coolers, and the surfaces of intake systems. This reduces airflow efficiency and limits a vehicle’s ability to successfully dissipate heat. Over time, this type of restriction can dramatically reduce cooling performance. At DBA Silencing, we offer a number of aftermarket air intake systems specifically designed to keep your mining trucks breathing freely and remaining cool.
There are a number of other issues that can lead to cooling difficulties: inadequate coolant flow, clogged coolant pipes, undersized coolant pipes, flagging water pumps, exhaust system deficiencies, intake system inefficiencies, and improper upkeep. As you can imagine, it takes a great deal of work to keep house-sized mining trucks running smoothly. Regular servicing is necessary, however, to prevent costly failures in the field. We talk about how to look after exhaust arrays in particular in our blog post “DBA Exhaust System Maintenance“.
Warning Signs Of Mining Truck Overheating
In most cases, heavy equipment will demonstrate signs of thermal stress before a full-scale breakdown occurs. Recognizing these signals early can help operators avoid expensive downtime.
Common indicators include: loss of power, reduced hydraulic performance, increased fuel consumption, frequent engine stoppages, unusually high exhaust temperatures, rising coolant temperatures, coolant leaks, coolant loss, heat damage to hoses, heat damage to other components, and heat buildup inside the engine compartment.
If left unchecked, mining truck overheating can lead to irreversible damage such as premature engine wear. It may also result in the failure of components such as turbochargers, cylinder heads, and gaskets.
DBA Coolant Components
We’ve already mentioned DBA Silencing’s exhaust and air intake systems. Let’s turn our attention now to DBA’s coolant systems and individual coolant components. Our coolant units are hand-made by veteran welders using high-grade aluminized steel and heavy-duty flanges that we manufacture ourselves. When assembling these units, we apply multiple layers of specialized industrial coatings in order to improve the durability of our coolant parts and enable them to withstand the rigours of the extreme mine site environments we mentioned earlier in this piece.
Our coolant components are not only sturdier than many comparable products, they’re also lighter. This makes initial installations much easier for mine site mechanics. Same goes for repairs, particularly those involving the replacement of parts.
DBA coolant systems don’t just put smiles on the faces of mechanics; they also keep the accountants happy. This is because, to start with, they cost far less than not only their OEM equivalents but also other aftermarket alternatives. Perhaps more importantly, DBA coolant systems – when used in conjunction with DBA exhaust systems and DBA air intake systems and other DBA parts such as exhaust accessories and bellows – prevent expensive catastrophes such as truck fires. They also reduce mining truck overheating. This saves money in multiple ways: by decreasing unnecessary wear and tear on big-ticket items such as engines, by maximizing fuel economy, and by minimizing the lost hours that eat into mine site revenues.
