Construction equipment represents a significant investment for any business in the industry. Whether you've purchased your machinery outright or are renting it for a specific project, proper maintenance is essential for maximising performance, extending equipment lifespan, ensuring safety, and protecting your bottom line. In this article, our maintenance experts share their knowledge on keeping your construction equipment in optimal condition.

The Business Case for Preventive Maintenance

Before diving into specific maintenance practices, it's worth understanding the compelling economic reasons for implementing a robust maintenance programme:

Cost Avoidance

Regular maintenance is significantly less expensive than emergency repairs:

  • The cost ratio of preventive vs. reactive maintenance is typically 1:4 – every pound spent on prevention saves four pounds on repairs
  • Major component failures often lead to collateral damage, multiplying repair costs
  • Emergency service calls and expedited parts delivery incur premium pricing

Reduced Downtime

Equipment failures rarely occur at convenient times:

  • Planned maintenance can be scheduled during off-hours or low-utilisation periods
  • Unexpected breakdowns cause project delays, potentially triggering penalty clauses in contracts
  • The average repair takes 3-5 times longer than preventive maintenance operations

Extended Equipment Life

Well-maintained equipment lasts significantly longer:

  • Regular maintenance can extend overall equipment life by 20-40%
  • Postpones the need for capital expenditure on replacement machinery
  • Improves residual/resale value when upgrading equipment

Improved Fuel Efficiency

Maintenance impacts operational costs beyond repairs:

  • Properly maintained engines can improve fuel efficiency by 5-10%
  • With current fuel prices, this represents significant savings for equipment with high utilisation rates
  • Reduces carbon footprint and supports sustainability goals

Establishing a Preventive Maintenance Programme

A successful maintenance programme requires systematic planning and execution:

Documentation and Record Keeping

Effective maintenance begins with proper documentation:

  • Equipment Inventory: Create a detailed inventory of all equipment, including make, model, serial numbers, purchase date, and warranty information
  • Service History: Maintain comprehensive records of all maintenance activities, including routine service, repairs, and part replacements
  • Hour Meters and Usage Tracking: Monitor equipment utilisation to schedule service based on actual usage rather than calendar time

Maintenance Scheduling

Develop a structured maintenance calendar:

  • Manufacturer Recommendations: Follow OEM guidelines for service intervals and procedures
  • Tiered Maintenance Structure: Implement a system of daily, weekly, monthly, and annual maintenance checks
  • Digital Reminders: Use maintenance management software to generate automatic service notifications

Staff Training

Equip your team with the knowledge they need:

  • Operator Training: Ensure operators understand daily inspection requirements and can identify early warning signs of potential issues
  • Maintenance Staff Development: Invest in regular training updates for maintenance personnel, especially when introducing new equipment
  • Clear Communication Channels: Establish protocols for reporting maintenance concerns

Daily Inspection Essentials

The foundation of preventive maintenance is the daily inspection. These quick checks should be performed by operators at the start of each shift:

Fluid Levels and Quality

Always check:

  • Engine Oil: Check level and look for discolouration or contamination that might indicate internal problems
  • Hydraulic Fluid: Verify proper levels and look for cloudiness or foaming that could suggest air or water contamination
  • Coolant: Ensure proper level and concentration for season; look for contamination that might indicate head gasket issues
  • Fuel: Begin each day with a full tank to prevent condensation and check fuel filters for signs of contamination
  • DEF (for Tier 4 engines): Maintain adequate diesel exhaust fluid levels to avoid engine derating

Visual Inspection

Conduct a thorough walkaround looking for:

  • Leaks: Check underneath and around the machine for fluid puddles or drips
  • Hoses and Lines: Inspect for cracks, chafing, or bulges that could indicate impending failure
  • Belts: Check for proper tension, cracks, or fraying
  • Wiring: Look for damaged insulation, loose connections, or signs of overheating
  • Structural Components: Examine for cracks, bends, or excessive wear

Operational Checks

Before full operation, verify:

  • Warning Lights and Gauges: Ensure all indicators function properly during start-up
  • Controls: Test all controls for proper response and full range of motion
  • Brakes: Check functionality, including parking and emergency brakes
  • Unusual Noises or Vibrations: Be alert for sounds that might indicate developing problems
  • Tracks or Tyres: Inspect for damage, wear, and proper inflation (for tyres)

Critical Maintenance Areas

Beyond daily inspections, several key systems require particular attention in a comprehensive maintenance programme:

Engine Care

The powerplant of your equipment demands meticulous maintenance:

  • Air Filters: Inspect regularly and replace when necessary – a clogged air filter can reduce engine power by up to 20% and increase fuel consumption
  • Oil Changes: Follow manufacturer recommendations for intervals, but consider more frequent changes in dusty conditions
  • Fuel System: Replace fuel filters according to schedule and drain water separators regularly to prevent injector damage
  • Cooling System: Flush and replace coolant at recommended intervals and ensure radiator fins are clean and undamaged
  • Exhaust System: Check for leaks or restrictions and ensure after-treatment components (like DPF) are functioning correctly

Hydraulic System Maintenance

Hydraulic failures can cause catastrophic and expensive damage:

  • Fluid Analysis: Conduct regular oil analysis to detect early signs of component wear or contamination
  • Filter Replacement: Change hydraulic filters at recommended intervals – contamination is the leading cause of hydraulic system failure
  • Cylinder Inspection: Regularly examine hydraulic cylinders for leaks, rod damage, or binding
