• Issues caught early through consistent pre-op inspection save more significant repair costs versus unplanned downtime.
• Operator training and documented inspection results are essential for conducting adequate pre-use checks.

Why are Pre-Operational Checks Important for Equipment?

Pre-operational checks are the first step in ensuring the safe and productive operation of compaction equipment such as rollers, compactors, and pavers, and completing thorough inspections before each shift is critical in preventing downtime, reducing maintenance costs, and maintaining a safe working environment.

Preventing Downtime and Costly Repairs

Inspecting components like hydraulic hoses, tires, coolant levels, and filters can identify potential issues before they cause problems. – Leaks in hydraulic lines or low fluid levels could lead to breakdown if unchecked.

Inspecting hoses and checking reservoirs during pre-operational checks helps catch minor issues before they become more prominent and require more expensive repairs.

Similarly, worn tires, low coolant levels, and dirty air filters may not stop a machine from functioning immediately but could accelerate damage over time and increase lifetime maintenance needs.

Regular pre-use inspections allow operators to address such concerns during scheduled maintenance versus unplanned downtime.

Ensuring Operator Safety

Before equipment operation, pre-operational checks also focus on verifying the safety of significant systems like brakes, lights, and alarms. This helps ensure the operator has the full range of controls and safety features.

For example, checking that backup alarms are functioning correctly prevents injuries that could occur due to restricted visibility.

Similarly, inspecting electrical components like circuit breakers reduces the risks of shocks or fires. Such safety inspections give the well-site operator peace of mind and help secure worksites.

Maintaining Productivity

Minor issues addressed during pre-operational checks can otherwise lead to reduced productivity if not resolved. For instance, low fluid levels may cause hydraulic functions and ground-engaging tools like blades to work inefficiently.

Similarly, problems like flat tires cause machines to vibrate and consume more fuel. Regular pre-operational inspections allow such minor issues to be fixed before they affect an entire shift or day’s work. This ensures equipment and operators remain productive.

Key Areas to Focus on During Pre-Operational Checks

Thorough pre-operational checks require inspecting all significant components and systems of compaction equipment. This helps ensure safe operation and prevents minor issues from developing into more severe problems. Some of the critical areas to examine include:

1. Checking Fluid Levels

Proper fluid levels are essential for the smooth functioning of equipment. Checking items like hydraulic oil, engine oil, coolant, fuel, and battery electrolytes during pre-operational inspections is a standard practice. Low fluid levels could cause overheating or accelerated wear. Topping up reservoirs prevents fluid leakage issues as well.

2. Inspecting Tires and Undercarriage

Tires and tracks are among the most critical ground-engaging tools and require close visual examination for cuts, abrasions, cracks, flat spots, and abnormal or uneven wear. This helps catch issues like under-inflated or damaged tires early. Loose or missing track pins on pavers/rollers can also be addressed. Inspecting the undercarriage area helps detect problems like leaks in hydraulic lines running along it.

3. Evaluating Hydraulic Systems

Hydraulic systems face maximum pressure and heat during operation. Pre-operational checks provide an opportunity to inspect hydraulic oil reservoirs along with hoses and cylinders for leaks, cracks, or bulges. Function tests ensure the smooth operation of hydraulic rams and functions. This prevents hydraulic failures mid-shift, which can damage other components due to temperature and pressure loss.

4. Reviewing Electrical Components

Inspecting electrical systems like batteries, wiring, connections, lights, and alarms is important from a safety perspective. Corroded or loose terminals can cause overheating and malfunctions. Pre-operational checks help verify that all critical electrical components operate as intended before each use, reducing risks on work sites.

Developing an Effective Checklist

A standardized pre-operational inspection checklist ensures thorough examinations are performed consistently. It helps operators and inspectors avoid overlooking any critical components.

Items to Include

The checklist must list critical areas to inspect pre-use inspection across various systems. For compaction equipment operators, it should prompt checking fluid levels, filters, hoses, tires, ground-engaging tools, safety devices, controls, and more. This helps inspectors remember to examine all significant parts during their pre-op and also annual inspections.

Customizing for Different Machines

While the core items remain the same, checklists also need customization. For example, rollers will need specific checks for drums and mats.

Inspecting vibration functions may only be relevant for vibratory machines. Customizing checklists per machine model simplifies inspections for operators familiar with that equipment.

Implementing as Standard Process

Once finalized, the checklist should be implemented as a mandatory standard operating process across all shifts. New operators must be trained to use it as their guide for pre-operational inspections.

Supervisors can then ensure inspections are completed correctly and catch any non-compliances early. Over time, checklists help develop inspection as a habit critical for safe equipment operation.

Performing Detailed Visual Inspections

Beyond checking levels and operation, thorough visual inspections are necessary to catch any defects, leaks, or issues that may not be apparent otherwise.

Examining External Components

Operators must walk around equipment, carefully examining all external parts for abnormalities. This includes inspecting tires/tracks for cuts and wear, looking for hydraulic fluid leaks along hoses or from cylinders, and checking ground-engaging tools for damage or cracks. Moving parts and components like belts should also be inspected for cracks or looseness.

The interior cabin check involves verifying the operator seat and seatbelt for good working condition, controls for proper response, and gauges/alarms to ensure all are functional. Safety equipment like fire extinguishers and first aid kits should also be inspected for completeness.

Identifying Any Fluid Leaks

Since hydraulic leaks can cause failures, inspecting the entire machine, including hard-to-see areas underneath, for signs of spilled oils or leaking coolant is critical.

Drips or puddles detected during visual checks indicate developing issues that must be addressed to prevent component damage.

Thorough visual inspections catch minor defects before they worsen, helping reduce downtime and repair costs in the long run. Finding and fixing issues during pre-operational checks saves greater expenses down the line.

Testing Critical Systems

Merely inspecting for defects is not enough. Pre-operational checks must also confirm that critical systems perform as intended through function tests.

Testing Hydraulic and Electrical Functions

Simple tests like manually operating hydraulic rams and ground-engaging tools help identify issues like sluggish response or sticky controls. Similarly, testing the rotation/movement of electrical components like lights and alarms verifies their correct functioning. This prevents surprises mid-operation.

Ensuring Proper Operation of Controls

Thoroughly exercising all operator controls is essential. Controls for propel, steering, and attachments must be checked for proper calibration and response. Testing anti-vandalism measures and safety locks to verify they work as designed.

Checking Safety Devices

Critical safety features like backup alarms, emergency stops, and brakes require functional validation. This ensures equipment safety systems will activate promptly if needed.

For example, testing an emergency shut-off switch confirms the engine or hydraulics cut power immediately when engaged, preventing potential accidents.

Taking time to run equipment operator through controlled functional tests pays off in confidence that systems will perform dependably during operation. It also helps detect issues that visual checks alone may miss.
