6.3. Special High Wear Items Costs

Special items known as high wear items deteriorate and subject to wear and tear at a faster rate. These have a shorter life than the remaining parts of the equipment.

High wear items are components of machinery that wear out quickly due to their usage and the harsh conditions they operate in. This deterioration leads to a need for frequent replacements, making it crucial to understand their impact on costs related to operation and maintenance.

Think of the tires on your car; they get worn out much quicker than other parts of the car due to constant contact with the road. Similarly, high wear items on machinery like bulldozer blades and excavator teeth experience rapid wear and need regular replacement.

Examples include the cutting edge of a bulldozer blade, ripper tips used for loosening soil, and bucket teeth on excavators. These parts must be replaced more frequently due to their wear.

The cutting edge of a bulldozer blade is designed for tough jobs, and as it continuously works against hard materials, it wears down faster than the blade itself. Similarly, the tips of rippers and bucket teeth are prone to rapid wear due to direct contact with the soil, making them high wear items that require regular maintenance to ensure efficiency.

Imagine constantly scraping a hard surface with a wooden stick. Over time, the tip of the stick would wear down, and you would need to replace it to keep working effectively. Just like that, equipment must have their high wear items replaced regularly to maintain operation.

To calculate the hourly cost of high wear items, one must know the unit cost of the item and the expected life of the item. This information can often be sourced from past records or manufacturer handbooks.

Calculating the hourly cost of high wear items involves determining how much it costs to maintain them based on their lifespan and replacement frequency. For example, if a ripper tip costs $100 and lasts for 200 hours of operation, the hourly cost would be$100 divided by 200, equating to $0.50 per hour.

Think of it like budgeting for your smartphone. If your phone costs $600 and lasts for 3 years (or about 2,628 hours of active use), you could calculate that it costs you about$0.22 per hour to use your phone (since $600 divided by 2,628 hours equals approximately$0.22). Similarly, calculating the cost for high wear items helps in budgeting for machinery use.

Information regarding the expected life of wear items can often be obtained from manufacturer handbooks, which provide insights based on different operating conditions.

Manufacturers often provide detailed guidelines and data regarding the lifespan of various components under different operating conditions. This helps equipment managers forecast wear and replacement costs more accurately. Staying updated with this information is vital for effective budgeting and maintenance planning.

This is similar to following a maintenance schedule for your car as advised by the manufacturer. They might provide guidance on when to replace tires or change oil based on various driving conditions. Following such guidelines ensures that the car operates smoothly and reduces the likelihood of unexpected repair costs.
