The excavation depth of a small mini excavator is usually around 1-3 meters, as follows:
Generally, the maximum digging depth of a small mini excavator is about 2-2.5 meters. This depth can meet the needs of most small projects, such as pipeline laying, shallow foundation construction, etc.
Some smaller mini excavators with stronger performance, such as Kubota KX008-3, Bobcat E10, etc., have a maximum digging depth of 3 meters. The power and boom design of these models are more optimized and can provide more powerful excavation capabilities.
For deeper excavation tasks, such as foundation pit excavation, etc., the digging depth of small mini excavators usually cannot be reached. This requires the use of a medium or large standard excavator.
In addition to the performance of the machine model, the excavation depth is also closely related to factors such as the working environment and operating requirements. In some working environments with strong limitations, the maximum digging depth of small mini excavators will also be reduced.
The following is a detailed explanation of the digging depth characteristics of small mini excavators:
(1) Power performance determines the excavation depth
The engine power and hydraulic system performance of a small mini excavator are key factors in determining its maximum digging depth. Generally speaking, models with greater engine power and more powerful hydraulic systems have greater digging depths.
(2) Boom length affects excavation depth
The length of the boom is another important factor that affects the depth of the excavation. The long arm provides greater excavation breadth and depth. But at the same time, factors such as the overall size and center of gravity balance of the machine must also be taken into consideration to ensure the stability of the machine and operational safety.
(3) The working environment affects the excavation depth
Different operating environments will also affect the digging depth of small mini excavators. For example, when working in a small space, the maximum digging depth may be reduced due to restricted movement. On a wide site, the machine can give full play to its maximum digging depth.
(4) Operation requirements determine the excavation depth
Different engineering tasks also have different requirements for excavation depth. For some projects such as pipeline laying and shallow foundation excavation, an excavation depth of 2-3 meters can meet the requirements. But for large projects that require deeper foundation pits, small mini excavators are obviously not suitable.
To sum up, the maximum digging depth of a small mini excavator is usually about 2-3 meters, which can meet the needs of most small projects. For deeper excavation tasks, a medium or large standard excavator is also required. At the same time, the excavation depth is also affected by many factors such as machine model performance, operating environment and operating requirements.
In general, although the digging depth of small mini excavators is limited, they are still widely used in some engineering operations. With their compact and flexible body, they can show their talents in small spaces. This also makes them a new force in the current construction machinery market.
