When you buy an excavator you will really need to list all the requirements before hand. Once you know the exact need of your excavator you can select the proper size and the one that can manage the various work that you will need to do. A key selector for excavators is if you want to have tires or tracks. This is a very important decisions to make and will determine a bit of what tasks you can do, how flexible you will be and can also determine the output and the return of your investment.
If you go for tracks you are very locked down to your choice, if you select tires, you can always change tires depending on the usage requirement, if they change between jobs. You can change for various surfaces if needed and for various weather conditions. You can also mount “over the tire” tracks to reduce skidding.
With tires your excavator is much faster and agile, it can move around in small areas and can if you have some distances to cover a wheeled excavator is much faster than a tracked one. So by selecting one with wheels you can generally increase the output of projects that require this type of movements.
For certain difficult terrain tracked excavators have better traction and have better weight distribution on soft surfaces. This can be important for the stability and balance of the excavator when lifting heavy objects. Also it reduces the impact on the ground, in case this needs to be minimized. Tracks can though often get through tougher terrain and soft terrains better. Also the tracks are not subject to damage by sharp objects, like stones and other debris.
Tracks are also better at getting up steeper slopes in terrain and can carry heavy loads up and down. However they move slowly, so it can be a bit tedious if the distances are long. For hard surfaces getting up and down slopes should not be a big issue for good tires.
The transportation between projects can be reduced, as the excavator with tires can drive on normal roads and do not have to be transported by another vehicle between jobs. This can save both time and money.
If you do go for excavator tires, then you need to make sure that your tire selection is correct and that is not always an easy task. There are a lot of tires to choose from and a lot of different brands. It goes without saying that you want to have a good tire with very good durability. Tire failures can be very costly and can easily delay certain projects. The tires will determine your stability and your grip on different terrains. Check the technical manual to get more information regarding your tire selection, to ensure that you get the right tires for the right speed and load. The tire pressure is also dependent on these factors.
