Excavator track shoe selection method
When buying an excavator, many people will be entangled: Is the width of the crawler track shoe of the excavator still narrow? Some people say that the wide does not trap the car, and some people say that the narrow fuel-efficient runs fast. So how should we choose the track shoes? Let's take a look together.
Without trapping, the narrower the track, the better
Different track shoes have a great impact on the production efficiency of the excavator and the service life of the chassis system. The choice of track shoes should comprehensively consider factors such as ground conditions, application conditions and the wear life of the chassis parts.
When the width of the track shoe increases, the buoyancy of the track shoe increases and it can adapt to more working conditions; however, the maneuverability of the bulldozer decreases, and at the same time the structural life of the track shoe and other components of the bottom plate also decreases. In addition, the wider the track shoes, the greater the friction with the ground, the greater the power loss caused by driving, and the higher the fuel consumption of the excavator.
So the track shoes are not as wide as possible. A basic principle when selecting track shoes is: The narrower the track shoes, the better, when the excavator is guaranteed not to trap the car during work.
Single tendon vs self-cleaning, which one should I choose?
At present, the most common on the market are single-reinforced track shoes and self-cleaning track shoes. What are the advantages and disadvantages of these two types of track shoes, and how do I choose?
Single-reinforced track shoes are the most widely used track shoes with good penetration and traction. They are used in standard excavators and are suitable for use under normal working conditions. If you work in a mine, construction site, or dry soil, you can basically use single-reinforced crawler shoes.
But when working on soft and wet soil, single-reinforced crawlers are easy to sink, and chain plates are quickly filled with clay. At this time, self-cleaning crawlers are needed. The self-cleaning track shoes are V-shaped and generally made of cast steel. When moving around the sprocket and guide wheel, the self-cleaning track shoes are separated from each other, so that debris can fall and can play a self-cleaning role. This kind of track shoe is only used for wet ground excavators with low ground pressure. It is suitable for soft, wet / muddy ground and can withstand little or no impact on the ground.
The above is an introduction to the selection of track shoes. I believe that after the introduction, everyone should know how to choose a track shoe.
