The importance of routine checks in reducing equipment downtime cannot be over-emphasised in your operation. Here, we cover key areas for inspection both before and after shifts. For operators and maintenance teams, this guide should outline the benefits of consistent equipment checks in preventing costly breakdowns.
Reducing Downtime: The Importance of Routine Checks on Heavy Machinery
In the world of construction, mining, and other heavy industries, downtime is a major concern. Whether you’re operating excavators, articulated dump trucks, or other earthmoving machines, any disruption in machinery operations can lead to significant delays and costly setbacks. These machines are the backbone of large-scale operations, and their consistent performance is vital to project timelines and budgets.
One of the most effective ways to minimize downtime and keep equipment running smoothly is through regular, routine inspections. By performing pre- and post-shift checks, operators and maintenance teams can identify potential issues before they escalate into major problems.

Understanding the Impact of Downtime
Before diving into the specifics of routine checks, it’s important to understand why reducing downtime is so critical.
Heavy machinery, such as excavators and articulated dump trucks, are costly investments that require proper care to maintain their functionality. Downtime can lead to several negative consequences, including:
- Delays in Project Completion: If equipment breaks down during a crucial stage of a project, it can lead to significant delays, ultimately pushing back deadlines and affecting other parts of the project.
- Increased Operational Costs: The longer equipment sits idle due to repairs, the higher the labor and equipment rental costs. Additionally, emergency repairs are often more expensive than routine maintenance.
- Damage to Equipment: Skipping regular inspections can result in small issues going unnoticed, which can escalate into major problems, requiring costly repairs or even replacement.
- Safety Risks: Faulty machinery can pose a safety risk to operators and other workers on-site. Preventing malfunctions through routine checks helps ensure a safer working environment.
By proactively checking and maintaining machinery, operators and maintenance teams can catch issues early, extend the life of the equipment, and minimize the potential for costly breakdowns.
Routine Checks: A Critical Preventative Measure
Routine checks are designed to prevent unexpected failures and to ensure that machinery is operating at peak performance. Whether performed daily, weekly, or between shifts, these checks help identify issues before they impact the project. They also provide an opportunity to address smaller problems before they turn into larger, more expensive repairs.
Regular inspections not only enhance the reliability of your fleet but also foster a culture of proactive maintenance, which is essential for minimizing downtime. Here are key areas to inspect before and after shifts to ensure that your earthmoving machines, like excavators and articulated dump trucks, stay in optimal working condition.

Pre-Shift Inspections: Start the Day Right
Before beginning any work, operators should carry out a thorough pre-shift inspection of the machinery. These checks are essential for ensuring the equipment is ready for the tasks ahead. The following are critical areas to focus on during a pre-shift inspection:
a. Fluid Levels
- Engine Oil: Check the engine oil level and ensure it is within the recommended range. Low oil levels or dirty oil can cause the engine to overheat or seize.
- Coolant: Check coolant levels to prevent overheating. A lack of coolant can cause the engine to run too hot, which can lead to expensive engine repairs.
- Hydraulic Fluids: Ensure that the hydraulic fluid is at the correct level. Since hydraulic systems control the movement of components like arms, buckets, and blades, a shortage can compromise the performance of these essential functions.
- Fuel: Always check the fuel level before starting a shift to ensure the equipment won’t run out during operations.
b. Tyres and Tracks (for Excavators and Articulated Dump Trucks)
For machines that rely on tires or tracks, checking their condition is crucial:
- Tyres: Ensure that the tires are properly inflated and free of any punctures, abrasions, or other damage. Uneven tyre wear can lead to poor performance and may require early tire replacement.
- Tracks: For tracked machinery like excavators, check the track tension and look for any signs of damage or wear, such as cracks or missing pins. Unevenly worn tracks can lead to uneven ground contact and poor performance.
c. Brake System
Test the braking system by applying and releasing the brakes while the machine is stationary. Make sure the brakes respond appropriately and there are no unusual noises or signs of wear. If there is any irregularity, the brake system must be inspected immediately.
d. Lights and Signals
Inspect the machine’s lights, including headlights, brake lights, and signal lights. Proper lighting is essential for visibility, especially if the worksite operates at night or in low-light conditions. Ensure that all lights are functional and that they provide adequate visibility.
e. Safety and Emergency Equipment
Check that all safety equipment, such as fire extinguishers, backup alarms, and first aid kits, is in place and in good condition. Ensure that the operator’s seatbelt and other safety features are functioning correctly.
f. Hydraulic Systems
Look for signs of leakage around hydraulic hoses, cylinders, and pumps. Hydraulic fluid leaks can not only cause environmental hazards but can also lead to a drop in hydraulic pressure, affecting machine performance.
g. Engine and Battery
Check the battery terminals for corrosion and ensure the battery is fully charged. Inspect the engine for any loose connections, exposed wiring, or signs of wear. Also, listen for unusual sounds when starting the engine, as this could signal a mechanical issue.
Post-Shift Inspections: Wrapping Up for the Day
After each shift, it’s equally important to conduct a post-shift inspection. This ensures that any issues that may have developed during the day are identified and addressed promptly.
a. Visual Inspection for Damage
Conduct a general visual inspection of the entire machine for any visible damage or wear. Check for cracks, loose bolts, and other signs of distress that may have developed during the shift.
b. Clean Equipment
Clean the machinery thoroughly at the end of each shift to remove dirt, debris, and materials that may have accumulated during the day. Excess dirt or mud can interfere with machine components and lead to overheating or increased wear.
c. Lubrication
Ensure that all moving parts are adequately lubricated. This helps to minimize friction, preventing parts from wearing out prematurely. Check lubrication points such as joints, bearings, and bushings and top off as needed.
d. Document Any Issues
Document any irregularities or issues noted during the post-shift inspection. Reporting these issues to the maintenance team early helps prevent potential breakdowns and keeps operations running smoothly. A maintenance log should include details such as the time, nature of the problem, and any immediate corrective actions taken.
Preventative Maintenance: Scheduled Checks Beyond Routine Inspections
While daily pre- and post-shift checks are essential for minimizing downtime, regular, scheduled maintenance is equally important. Depending on the machine type and manufacturer’s guidelines, operators and maintenance teams should schedule more comprehensive checks, such as:
- Fluid flushes and changes
- Belt and hose replacements
- Comprehensive hydraulic system checks
- Full battery and electrical inspections
- Detailed undercarriage inspections for tracked equipment
Staying ahead with scheduled maintenance can prevent many of the problems that arise from wear and tear, keeping machines in peak condition for longer.
A Commitment to Preventative Maintenance
Whether you’re working with earthmoving machines like excavators, articulated dump trucks, or other heavy-duty equipment, taking a proactive approach to maintenance can save significant time, money, and effort in the long run. Regular inspections aren’t just about avoiding breakdowns—they’re about fostering a culture of responsibility and foresight that benefits both the workers and the overall project.
