When it comes to excavators, many people may think of the phrase "excavator strikes 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, if you choose the most appropriate excavator according to the project scale and supporting equipment, you will get twice the result with half the effort.

Project scale

Crawler type hydraulic excavators can be generally selected for working conditions and occasions with large amount of maneuverability and poor working conditions. The hydraulic excavator with narrow track and heavy weight shall be selected for the working conditions with strong ground bearing capacity, uneven, many potholes or hard bulk ores; On the contrary, if the ground bearing capacity is weak and the soil is loose, the broadband extended excavator shall be selected.

The design institute or relevant experts shall analyze, compare and scientifically calculate the large-scale earthwork engineering and medium and large-scale open-pit mine engineering according to various factors such as total investment and supporting equipment, and determine the specifications, models and quantities of hydraulic excavators to be purchased. For general periodic small and medium-sized projects, such as road maintenance and irrigation and water conservancy, it is only necessary to select ordinary excavators. For example, the widely used excavators between 20-25T can fully meet the requirements.

Rubber tyred hydraulic excavator shall be selected for small quantities, good working conditions and frequent change of working surface; Backhoe and long arm working devices can be selected when cleaning and dredging the riverbed or waterway; At the same time, a variety of working devices can be ordered so that they can be replaced at any time according to the 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 compatibility with our existing equipment, including the matching between the operating efficiency of excavators and the operating efficiency of existing equipment. For example, although the price of small excavators is low, they do not match with large dumpers, which is equivalent to "small horses pulling big cars", and "large horses pulling small cars".

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, including installment payment, bank mortgage or other methods. If there is no problem in terms of funds, we can consider optimizing our own equipment structure and purchasing equipment with big brands and excellent after-sales service, which will also invisibly improve the competitiveness of our own contracted projects.
