Select a bucket with right capacity for your excavator

Large-sized hydraulic excavators are frequently used for the unloading work in the quarry project. Actually, this machine is of great significance for the whole pace of the project. Choosing the right bucket and teeth at the end of the stick will not only be helpful to reduce the operation costs, but also improve the productivity, probably more than you think.

Capacity is the main factors in bucket selection. To have a right capacity bucket, you need consider beforehand the machine lifting and breakout capabilities, material density and also the truck match. Machine capacity means how much lifting force the machine has for the bucket and payload at a given reach. Material density tells you the weight of a bucket load at ideal 100-percent fill conditions. The rock and stone fill is an exception, and usually, we estimate a 90 percent fill factors or less for shot rock.

At last, but not least, is the truck match, which actually is a prerequisite factor to think about in deciding the size of the bucket. Generally speaking, four or five passes is a perfect match for a large excavator in the 75-100 ton size. But if you need faster loading speed, you need think again the size and configuration of the bucket. It’s worth mentioning that a bigger bucket doesn’t always reduce loading time, since it may lead to less flexibility in digging and the resulting less production gain.

Excavator Operating Techniques

When operating excavator, we should pay attentions to the around environment like the barriers and terrains. Pay attentions to the crawler belt to avoid collision or tipping over. Make both of the crawler belts completely touch with the ground to improve stability. The digging power is the maximum when the angle between the bucket cylinder and the rod is 90°. The cutting power is the best when the angle between the bucket teeth and the ground is 30°. The bucket rod working angle should be kept between 45°in the front and 30°in the back. And it can improve the digging efficiency when use the arm and the bucket at the same time. excavator for sale.

The large and hard rocks will damage the bucket, so some techniques should be mastered when digging in the complicated terrains. The machine body should be positioned towards the cracks of the rocks and make sure that the bucket teeth can easily insert the cracks. Only when the rocks are crashed can the excavator starts to dig. When leveling the slope, the excavators should be positioned stable and balanced. And the arm movement should be accordance with the rod movement, which is very important for the slope leveling.

When it refers to loading and unloading, good cooperation between the truck and the digger is very important, which means that the two machines should make consistent action. Both of the machines should be kept stable, otherwise, it will be hard to control the rotation and extend the working time. The hydraulic excavator should keep proper distance with the truck to avoid any collisions during the working process. Generally, the truck should be positioned lower than the digger, which can shorten the arm lifting time and provide a good vision for the operator. According to the loading experience, the sand and rubbles should be loaded before loading the big rocks, which can effectively reduce the collision to the carriage.
