For construction, demolition, road building, and a variety of other jobs, equipment and fuel represent significant investments and constitute a large portion of your operational costs. Excessive idling can drastically increase these already substantial expenses. For instance, one manufacturer estimates that a 36 ton excavator operating 1,000 hours annually consumes 400 gallons of fuel while idling. To help you avoid this waste, we've compiled some strategies and recommended practices to reduce idle times and prevent unnecessary wear and tear.
Engine idling occurs when equipment is left running while not in active use or motion. This practice can significantly affect your profitability, decrease machine efficiency, and waste valuable resources in several ways:
The adverse effects of "ghost hours" or idling time aren't immediately obvious, but they can gradually diminish the value of your assets. Consider two machines, A and B, both with 5,000 working hours, but machine A had considerably more idle time. At resale, machine A shows 10,000 total hours while machine B shows 7,500. This 2,500-hour difference can significantly impact the sale price, potentially up to $20,000, depending on the machine's size and type – all due to excessive idling.
Despite its numerous negative impacts on business profitability, engine idling remains prevalent on construction sites. However, there are tactics you can employ to minimize idling as much as possible.
It's crucial to ensure your equipment operators understand the financial implications of idle times and the importance of improving overall machine efficiency. They should internalize the principle that if the equipment isn't actively working or performing a necessary function, it should be turned off. Encourage shutting down engines if they're likely to idle for more than 10 seconds. Some companies even implement incentive programs for operators who consistently and effectively reduce idle times, resulting in substantial gains for your bottom line.
Improving machine efficiency requires understanding what's hindering it in the first place. Modern technology and tools enable more precise equipment monitoring, data collection, and conversion of raw data into actionable insights. Most of these machine monitoring systems allow you to view and track idle times. By identifying when engine idling occurs, you can take appropriate steps to educate operators or modify jobsite workflows, leading to better operational planning and reduced waiting times.
The more thoroughly you plan your project operations, the less time your equipment will spend idle, waiting to be loaded, unloaded, or to perform critical tasks. It's essential to allocate the appropriate number and type of machines to each jobsite to avoid redundancies or delays, which often result in idle time. Additionally, ensure your excavators and loaders are correctly sized for the specific work being undertaken. For example, when loading an articulated truck with an excavator, it should ideally take three to five bucket loads to fill the truck bed. If it takes more than five loads, you're likely to have machines idling, wasting time and fuel.
Many new equipment models include features that help operators significantly reduce engine idling and improve machine efficiency. While they may go by different names - such as auto idle, auto stop, auto start, or idle stop system - we recommend considering options that offer some form of idle limiting technology when purchasing new machinery.
