in the selection of digging machine, the following points you consider?

when it comes to excavators, many people may think of the phrase "when the excavator rings, there are ten thousand taels of gold". Yes, as one of the most important construction machinery in engineering construction, excavators can indeed bring considerable economic benefits to all of them. However, this "considerable" is closely related to "suitable. In other words, according to the scale of the project you have to face, engineering equipment, etc., choose the most suitable excavator, you will get twice the result with half the effort.

Project scale
Working conditions and mobility engineering large, poor working conditions of the general choice of crawler hydraulic excavator. Among them, the working conditions of strong ground bearing capacity, uneven, multi-potholes or hard large pieces of ore should choose a hydraulic excavator with a narrow track weight; on the other hand, if the ground bearing capacity is weak and the soil is loose, the working condition should choose a broadband extension Long excavator.

Large-scale earthworks and medium-and large-scale open-pit mine projects should be analyzed, compared and scientifically calculated by the design institute or relevant experts in accordance with various factors such as total investment and supporting equipment to determine the specifications, models and quantities of hydraulic excavators to be purchased. General periodic small and medium-sized projects, such as road maintenance, irrigation and water conservancy, only need to choose ordinary types of excavators, such as widely used between 20-25T models of excavators can fully meet the requirements.

Tire-type hydraulic excavator shall be selected for small quantities, good working conditions and frequent changes of working surfaces. Backhoe and long arm working devices can be selected when cleaning and dredging riverbed or waterway. At the same time, various working devices can be ordered to be replaced at any time according to construction needs, such as front shovel, backhoe, grab bucket, hydraulic hammer, drilling and other working devices for selection.

Engineering supporting equipment
When purchasing excavators, we should consider the matching with our existing equipment, including the matching of the working efficiency of excavators with the working efficiency of existing equipment. For example, although the price of small excavators is low, it does not match with large dump trucks, which is equivalent to "small horse-drawn carts" and "large horse-drawn carts.

Of course, in addition to the above two points, users should also consider their own capital situation, so as to consider which purchase method to choose according to the capital situation, whether it is installment payment, bank mortgage or other methods. If there is no financial problem, you can consider optimizing your own equipment structure and purchasing equipment with big brands and excellent after-sales service, which will virtually enhance the competitiveness of your own contracted projects.
