How much dirt can an excavator move an hour?

An excavator is a construction vehicle with a boom and bucket. It is usually equipped with a front loader for digging and loading debris. The excavator moves around on tracks, and the operator sits in an enclosed cab at ground level, out of sight from other workers. They use an excavator to remove excess dirt when making ditches, trenches or building underground tunnels. How much dirt an excavator can move per hour depends on its size, type of material being worked and how skilled the operator is.

How Much Can Dig in a Day?

Planning is the vital step that ensures you know where to start from and how to get to your end goal. Efficient project management can mean hundreds of hours saved for you and your team, so it’s worth taking the time to get it right.

whatever you will be doing to get your job done, whether it is digging a trench or operating an excavator on a construction site, having all the right equipment in ready when you need it is at the heart of any good site or project.

1. equipment 

The excavator you choose will be one of the most important pieces of equipment on site, especially if you want to make your job easier. It can also be one of the most expensive pieces of equipment too if you want a more powerful machine. If this is the case then it’s important to consider the size of your bucket capacity as this will dictate how useful your excavator is.

The amount of weight an excavator can carry is obviously a critical aspect in determining its capabilities. Lifting capacity is generally measured in cubic yards and is responsible for how much material you can move in a day. As a standard amount, you can expect an excavator such as the Komatsu PC200 Series Excavator to move 40 cubic yards in an hour, but this will vary based on what you drive.

2.Other factors

The first of these being the type of dirt you’re attempting to remove, as wet or sticky soils are going to be much harder for your equipment to dig through than dry dirt. The next factor is the weight of your excavator’s bucket, as some bulldozers have huge buckets that will easily lift up and move large amounts of loose materials like sand and gravel.

A good excavator can make all the difference when it comes to getting an excavation site cleared effectively. Most compacted detritus that you encounter in these situations needs to be broken up first, so having an excavator which is able to do this for you can help you save a lot of time and energy. A rock or root that is embedded in the ground where you are digging can also prove difficult to work around as well, but having an excavator will allow you to break through these obstacles too.

The driver of the excavator is one of the most important factors in how efficient your excavator is. He or she can determine how quickly and efficiently the digging process happens, which in turn will reduce your overall costs by increasing efficiency and lowering fuel consumption.

You couldn’t get the job done without them, so why not make sure your excavator driver is fully trained and experienced? Having a well trained and experienced excavator driver can help you get the most out of your excavation site, by making it as efficient as possible.

How to Calculate Excavator Productivity?

When it comes to excavator productivity, the most common measurement is the volume of loose or rock soils moved in a hour. In other words, the productivity of an excavator is determined by the volume of soil it can dig up in a minute. The calculations for excavator productivity are straightforward and can be simply completed on a standard calculator.

Owning an excavator with higher productivity will make you work faster, which makes you earn more money.

1.Derek Jones, an American engineer and author of “The Operator’s Manual for Excavators”, offers the easiest way to calculate excavator productivity for any site. The formula is as follows: Q = (60_q_z_n_kf) / kl.

2.A field study is being conducted to measure the productivity of an excavator-load digging machine (also called a backhoe). The productivity and capacity of the excavator are measured at three different speeds: 10, 20 and 30 rpm. The results show that P = 2.3qzn20 – 1.4kf – 0.4kl.

3.Essentially, a capacity factor is the percentage of time spent in activity related to the specified work effort. To determine an excavator’s capacity factor, use your excavator’s manual and look up the capacity of each rotor bucket in cubic feet, the number of buckets on the wheel and its speed of rotation. Next, calculate the filling factor for your excavator; this determines how much potential each bucket has for holding soil. Then, determine its soil-loosening factor (SFL); this indicates by how much each bucket loosens soil above its density. Finally, multiply these values together and you have your excavator’s capacity factor in percent.

4.Excel can be used to calculate excavator productivity. To calculate the productivity, use the formula in Step 1 of this tutorial. For instance, if the excavator has a capacity of 10 cubic feet for each bucket and there is only one wheel with a bucket and it rotates at 5 rotations per minute, then kl = 1. Also, kf = 1 and qz = 60 cubic feet per minute. Based on these inputs, we get Q as 3,000 cubic feet per hour.

5.The relationship between kf and kl is determined by the material characteristics of the soil. Filling factor describes the amount of earth that fills in a bucket while loosening factor pinpoints the amount of soil that can be easily broken up with a shovel.


Excavators are heavy-duty machines that require delicate and proper care when operating. Various factors, including the bucket size, soil conditions, excavator engine’s power, and operator’s skill can determine how much excavation can be completed in a day. So before hiring one for your project, you need to have a better idea and understand the nature of the job you want to do.
