For those of you unfamiliar with these machines, mini excavators are basically smaller, more compact versions of the larger diggers that you see on construction sites. They are often used on smaller jobs (such as houses) and when more confined spaces are present, as they’re able to maneouvre in these sorts of areas with ease. When dealing with excavators, it is important that you have carefully considered the tracks that they will be fitted with.
These tracks, which are generally made from rubber, are actually comparable to the tyres on a regular tractor. They’re responsible for the machine’s mobility, performance and durability. Whilst most tracks will last around 24 months or 2000 hours on average, there are some situations in which they may not last anywhere near as long or may last far longer. When it comes time to replace your tracks, it’s important that you’ve made a careful decision.
Firstly, you have to determine whether you want to purchase original equipment manufacturer (OEM) parts or aftermarket ones. Whilst there is nothing wrong with either choice, it does pay to be familiar with them:
OEM Parts – These are tracks that the original manufacturer of your mini excavator have also created (or have specified for use with their machines if they don’t have the ability to manufacture). It should be noted that this tends to be the more expensive option.
Aftermarket Parts – These are tracks that have been made by a third party and are often designed to fit excavators for a variety of brands. It is possible to pick up a quality product if you purchase through a reputable dealer. They do tend to be the more affordable option, too.
No matter which option you have selected, it is important that the tracks fit perfectly and that the tension is adjusted to an acceptable level. Tension is a key factor in guaranteeing the mobility and maneuverability of your excavator, as well as for ensuring safety and uniform wear and tear. Tracks that are too loose or too tight can cause all sorts of issues; we have outlined some of these to drive home the importance of correct tensioning.
If the tracks are too loose, there is a chance that they will ‘de-track’, which can cause damage to the mini excavator and endanger the operator. If the tracks are too tight, they can cause unnecessary wear and tear on the machine and will also power through fuel (which will end up costing you a significant amount of money). Another issue of tracks that are too tight is that they can snap, which could create a hazardous situation for the operator.
To ensure that your mini excavator’s tracks remain in tiptop condition, they should be inspected after every 100 hours of use (at least). The tension should be cross-referenced with the manufacturer’s guidelines to ensure that they have been adjusted properly. If purchasing aftermarket tracks, they should come with an extended warranty that protects against manufacturer defects and faulty materials. Finally, ensure that they’re replaced when necessary.
