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.
