5 technical specifications to correctly buy a new excavator
Choosing the specifications of an excavator is the critical step to get the right purchase of new equipment since these have a direct influence on satisfying the labor demand that arises on site.
It sounds relatively simple, but it involves a large number of features, in the following paragraphs you will know roughly 5 characteristics of excavators that you should consider prior purchase:
1.- Equipment size, its tools and, define its purposes.
Matching the dimensions of your future excavator, the size of its tools, and the purpose in which it will be used is the most important part of a purchasing decision. Equipment manufacturers generally designate a classification by size:
Compact excavators: Adapted for minimal excavation or landscape modification projects. The buckets used in this class of equipment are usually less than one cubic meter capacity.
-Medium size excavators: Used in medium-size excavation projects, they usually use service buckets with volumes ranging from 2 cubic meters or less.
-Large excavators: Used in excavation and massive movement of material. Their service buckets are capable of easily reaching 4 cubic meters or more.
2.-Choose the tools.
The tools designed for excavators are vast, by choosing the right equipment will provide maximum versatility when carrying out different tasks. To make adaptable purchases, you must analyze the pressure values provided by the hydraulic oil flow of your machine and that this is always within the operating pressure range of the tool. For example, this is a basic rule when purchasing a hydraulic breaker.
3.-Equipment controls
There are two predominant control configurations for excavators on the market, the ISO and SAE type controls. In recently created vehicles, most manufacturers incorporate a pattern selector according to the operator’s needs. If the vehicle you are about to purchase does not have this type of control alternator, consider purchasing the predominant one in your region, for Latin America, it is usually the ISO controls.
4.-Undercarriage.
There are multiple configurations in the equipment undercarriage each with different benefits, the most common will be:
-Long: They benefit the stability of the excavator on uneven terrain.
-Long and narrow: They benefit stability and allow better operation in tight spaces.
At the same time, these may be provided with shoes of some of these types:
-Single grouser track shoes: Ideal for maintaining a maximum level of penetration into the ground, they are used in rocky terrain maintaining the best traction of all the shoe configurations.
-Double grouser track shoes: They maintain a medium level of penetration into the ground, improving the maneuverability of the vehicle when making turns with the tracks.
-Triple grouser track shoes: Their penetration level is lower than the aforementioned configurations, ideal for soft or soft soils.
Concerning the size of the tracks, the wider will provide better traction.
5.- Additional technologies:
Newer-generation excavators often have auxiliary hardware and software for cutting precision, fuel consumption control, systems that improve operator visibility through strategically placed cameras to reduce blind spots. Analyze if they are optional and consider those that best suit your tasks and budget.
