Efficiency and Safety Benefits of Using Mini Excavators
There are significant benefits to operating your mini excavator efficiently and safely that every operator should recognise.
Increased productivity:
By operating efficiently and maximising productivity, you can complete more projects and tasks in less time. An efficient operator achieves objectives with less effort and in fewer work hours. Smart techniques allow you to dig more soil, level more surface area or demolish more structures per day.
Cost savings:
Higher efficiency means lower costs in terms of time and fuel. Less operating time translates to labour and project schedule savings. Efficient operation also saves fuel that would otherwise be wasted due to excessive idling or incorrect techniques.
Injury prevention:
Following proper safety protocols minimises the risk of damage and injury on the job site. Carefully honed skills prevent accidental contact between the excavator and nearby people or objects. This helps to maintain a safe work environment for both the operator and other workers.
Reduced wear and tear:
Proper operation puts less strain and stress on excavator components. Lower impact loads on the boom and smooth hydraulic valve control extend the life of cylinders and hoses. This reduces the need for premature replacement of parts.
Better results
Overall, good operational techniques lead to better project outcomes, enabling you to work quickly yet safely. Taking the time to master the operation of a mini excavator pays off in terms of increased efficiency and safety.
Pre-operation checks:
Conducting thorough pre-operation inspections of your mini excavator is one of the most important safety tips. Taking the time to check key components and functions helps to identify any issues before they cause problems during use. Don’t skip this crucial step.
Inspect the Equipment
Begin by carrying out a visual inspection of the entire excavator to check for any damage, wear or missing parts. Check for cracks or leaks in the hoses and cylinders. Check the tracks for cuts, missing cleats or incorrect tension. Ensure that all lights and mirrors are present and functioning correctly. Ensure that the mini excavator's attachments are properly secured. Detecting any issues early allows for timely repairs.
Fluid levels:
Use dipsticks or sight gauges to check the engine oil, coolant and hydraulic fluid levels. Add oil or fluid as needed until it reaches the 'full' mark. Low fluid levels can cause catastrophic engine and hydraulic system failure. Refer to the owner’s manual for instructions on checking and adding fluids.
Safety Features:
Ensure that all safety features are active and functioning correctly. Ensure that the horn, backup alarm, seat belt and rollover protective structure are all present. Ensure that the safety levers and switch disable the excavator’s operation when activated. Malfunctioning safety components can seriously endanger the operator.
Other important pre-operation checks include:
- Inspect fuel lines and fuel filters for leaks.
- Drain water and debris from the fuel filter and air filter.
- Check tires and lug nuts on any trailer used to transport the excavator.
- Test brakes to ensure proper operation.
- Examine the condition of safety decals and warning labels.
- Ensure the fire extinguisher is charged.
The pre-operation walkaround takes 10 to 15 minutes but identifies issues before they become major problems. Develop this inspection routine before each use to keep hazards in check. Taking this preventive measure gives you peace of mind knowing your excavator is ready to work.
Efficient Excavation Techniques
Using a mini excavator to properly excavate footings allows you to work quickly and productively. Follow these tips for efficient digging.
Proper positioning:
Position the excavator as close as possible to the digging area. This reduces the need to reposition the machine constantly between bucket loads. Place it in a spot that gives you the best view of the entire area to be excavated.
Bucket approach:
Angle the bucket at an angle of 30 to 45 degrees towards the ground or the material being excavated. This enables you to cut deeper with less resistance than if you were to dig straight down. The angled approach makes material removal easier and provides better breakout force.
Avoid overloading:
Never attempt to dig or lift loads that exceed the excavator’s weight capacity. Overloading can strain components and cause tip-over accidents. Refer to the operator’s manual for information on rated lifting capacities, digging depths and slope operation limits.
Navigating terrain
Operating over rough or uneven terrain presents challenges that you must be prepared for. Follow these guidelines when working in less-than-ideal ground conditions.
Understanding the terrain:
Inspect the work area and identify any hazards or limitations before starting. Take note of particularly soft or muddy areas that could impede movement. Look out for hidden holes, trenches or rocks that could damage the undercarriage.
Track Maintenance
Keep the tracks properly tensioned and clean to prevent debris from building up. Full-length rubber tracks offer optimal traction on loose or wet ground. Make sure that the guides and rollers are in good condition to prevent derailment during operation.
Operating on slopes:
Exercise extreme caution when digging or travelling on hilly or sloped terrain. Always follow these safe operating practices.
Safe angles:
Familiarise yourself with your excavator’s maximum longitudinal and lateral tilt capacities, and ensure that you do not exceed them. Generally, slopes of up to 30 degrees forward or backward and 10 degrees sideways are safe. Anything beyond that increases the risk of accidents.
Downhill operation:
Drive straight down steep slopes without turning the tracks. Turn the boom uphill to counterbalance. Keep the bucket and load low, but off the ground, while descending. Move slowly and use the counterbalance function.
Uphill operation:
Drive straight uphill without turning. Keep the boom tucked behind the cab and the load lowered. Take care, as the machine could tip backwards if the tracks lose traction. First, check the ground conditions and avoid overly wet or loose soil.
Maintenance tips:
Proper excavator maintenance improves safety and prevents the need for costly repairs in the future. Follow these best maintenance practices.
Regular cleaning:
Make a habit of washing the excavator after each use to remove mud, dirt and debris. Keeping the tracks, boom and cab clean makes them easier to inspect and prevents build-up.
Scheduled servicing:
Follow the recommended schedule for lubrication, oil changes, filter replacements and other services, as outlined in the owner's manual. Do not skip intervals, as delayed maintenance accelerates wear and tear.
Component inspection:
During regular servicing, take the time to inspect components for issues such as leaks, cracks and abnormal wear. Identify problems early to prevent failures during operation. Replace worn parts as needed.
