The excavator long stick introduction
The main advantage of a long excavator boom and arm is increased
reach and digging depth. With a longer boom and arm, an excavator
can reach further and dig deeper, allowing it to work on larger
projects or work from a greater distance without having to move the
machine. This can be especially useful in applications such as
excavation, mining, and construction, where the ability to reach
deep or far distances is often critical.
Another advantage of a long excavator boom and arm is increased
versatility. With a longer reach, an excavator can access areas
that might otherwise be difficult or impossible to reach, such as
deep trenches, high walls, or steep slopes. This can make it easier
to complete a wider variety of jobs with a single machine, reducing
the need for additional equipment and saving time and money.
However, it's important to note that longer booms and arms can also
lead to decreased stability, especially when the excavator is
working at maximum reach or digging depth. This can increase the
risk of tipping or overturning, which can be dangerous for the
operator and can cause damage to the machine and surrounding
structures. Therefore, it's important to use caution and follow
proper safety procedures when operating an excavator with a long
boom and arm.
