Hydraulic Functions in Mini Excavators16 May 2016
The use of mini excavators, which are also referred to as compact excavators, is steadily on the rise, as these can be used in areas and in certain conditions where their larger counterparts cannot. However, these are basically designed to function the same, just on a smaller scale, but the real reason for the growing use of compact excavators is because these are easy to transport, and simple to operate.
Mini Excavators and the Variety of Their Hydraulic Functions
Hydraulics are used in everything that an excavator does, big or small, all of its movements and functions are controlled through the transfer of hydraulic fluids. This is why earth moving equipment is so valuable and necessary for all types of digging work. For example, excavators are used in landscaping, excavating building foundations, creating holes for swimming pools, setting posts, not to mention the countless other uses needed on construction sites, such as moving materials and machinery safely, which are impressive feats of engineering that are often performed in close quarter environments.
To better understand how these little engineering marvels manage to move dirt as effectively as they do, using boom extensions such as a bucket attachment for digging trenches, large augers for digging post holes, stump grinders, and rotary hoes for tilling soil, then learning about hydraulic piston pump technology will help you.
Hydraulic Piston Pump Technology and How it Works
Today’s mini excavators are using hydraulic piston pump technology, which allows these little machines to do more with smaller engines by effectively utilising newer types of hydraulic piston pumps that require 20% less horsepower to operate than older pumps. That means newer hydraulic pump systems that combine gears and various hydraulic pumps, all working together, can operate multiple tasks at one time, with less horsepower.
A good example would be a mini excavator equipped with a bucket attachment, as it uses pumps to operate the boom arm, while at the same time using separate hydraulic pumps to swing the cab, and another to manipulate the bucket. There are different types of compact excavators, and many kinds of attachments to accomplish nearly any type of task, but they all do use hydraulics to function.
