Yo, fellow construction enthusiasts! I’m the guy behind a company that supplies 2 – 6.5Tons Mini Crawler Excavators. These machines are awesome, super versatile and can handle all kinds of jobs on small to medium construction sites. But one crucial thing that often gets overlooked is adjusting the tension of the crawler tracks. In this blog, I’m gonna share some tips on how to do that right. 2-6.5Tons Mini Crawler Excavators<\/a><\/p>\n

<\/p>\n

First off, why is track tension so important? Well, if the tracks are too loose, you’ll notice a lot more wear and tear on the track components. The tracks might even start slipping off the sprockets, which can be a real pain in the butt, not to mention dangerous. On the other hand, if the tracks are too tight, it’ll put extra stress on the undercarriage parts, like the idlers and track links. This can lead to premature failure and cost you a fortune in repairs. So, keeping the right track tension is key to making your mini crawler excavator last longer and work more efficiently.<\/p>\n

Now, let’s talk about how to check the track tension. You don’t need any fancy tools for this. Just take a look at the track between the front idler and the drive sprocket. There should be a slight sag in the middle. The ideal amount of sag depends on the size and model of your excavator, but generally, it should be around 20 – 30 millimeters for most 2 – 6.5Tons Mini Crawler Excavators.<\/p>\n

If you’re not sure if the sag is right, you can use a simple measuring tape. Just measure the distance from the bottom of the track to a flat surface under the excavator at the mid – point between the front idler and the drive sprocket. Compare this measurement to the manufacturer’s specifications. If it’s too high or too low, you’ll need to adjust the track tension.<\/p>\n

Before you start adjusting the track tension, make sure your excavator is on a flat and level surface. Turn off the engine and set the parking brake. Safety first, right? You don’t want the machine moving around while you’re working on the tracks.<\/p>\n

Most of the mini crawler excavators in the 2 – 6.5Tons range have a track tension adjustment mechanism at the front idler. This usually consists of a grease fitting and a spring – loaded tensioner. To loosen the track, you’ll need to release some of the grease from the tensioner. You can do this by using a grease gun to remove grease from the fitting. As you release the grease, the spring in the tensioner will compress, and the track will loosen up.<\/p>\n

To tighten the track, it’s the opposite. Use the grease gun to add more grease to the tensioner. As the grease is pumped in, the spring will expand, pushing the front idler forward and tightening the track. Keep adding grease in small increments, and check the track sag after each addition. It’s better to make small adjustments than to over – tighten the track.<\/p>\n

Another thing to keep in mind is that the track tension can change over time, especially if you’re using the excavator in rough terrain or for heavy – duty work. So, it’s a good idea to check the track tension regularly. I’d recommend doing it at least once a week, or more often if you’re using the machine intensively.<\/p>\n

When you’re adjusting the track tension, pay attention to the condition of the tracks. Look for any signs of damage, like cracks, worn – out links, or loose pins. If you notice any problems, it’s best to replace the damaged parts as soon as possible. A small issue can quickly turn into a big one if you ignore it.<\/p>\n

Also, make sure to clean the tracks regularly. Dirt, mud, and debris can build up between the track links and sprockets, which can affect the track tension and cause premature wear. You can use a pressure washer or a simple hose to clean the tracks. Just make sure to dry them thoroughly before you use the excavator again.<\/p>\n

Now, I know all this might sound a bit complicated, but once you get the hang of it, adjusting the track tension is a piece of cake. And trust me, it’ll save you a lot of headaches and money in the long run.<\/p>\n
