3 Key Types of Construction Vehicles

Grader Leveling Gravel On Road
The modern world continues to grow at a fantastic pace - one that far exceeds that of any other time in history. Construction equipment has grown and evolved in tandem with the rest of the world. In order to meet the fast-growing needs of today, an excavation contractor must use a wide variety of heavy vehicles.
Unfortunately, many people still haven't caught up with the staggering range of options when it comes to construction vehicles. If you would like to improve your knowledge of heavy construction equipment, keep reading. This article will provide useful introductions to three key types of construction vehicles used specifically within the world of excavation.

1. Trenchers

One of the most common excavation jobs involves digging narrow trenches in the ground. Such trenches house things like water pipes, electrical lines, and other types of utilities. Traditionally, trenches had to be laboriously dug by hand. As you can imagine, this process was both time consuming and labor intensive.
Trenchers make the job of digging trenches many times easier. These heavy machines can cut through the ground in mere seconds. Two main types of trenches exist: wheel trenchers and chain trenches. The former resemble circular saws, while the latter contain cutting elements much like those on a chainsaw, only far larger.
Each type of trencher has its own particular set of strengths and weaknesses. Wheel trenchers tend to be the more economical of the two, as well as easier to maintain. Wheel trenchers face limitations in terms of trench width; the circular cutting blade can only be so wide. Chain trenchers, on the other hand, come in a much greater range of sizes and are far superior for cutting wider trenches.

2. Motor Grader

Excavation and landscaping jobs often involve a grading phase. Here any loose dirt that has been piled up through the process of trenching or excavating must be distributed evenly. Motor graders make one of the best choices for spreading and leveling ground.
All motor graders contain a single wide blade mounted in the middle of the vehicle. The angle and orientation of the blade can be altered by the operator inside of the cab. Beyond this common feature, motor graders fall into two categories: rigid frame and articulated frame graders.
Rigid frame motor graders can be distinguished by the fact that they have only one axle. Articulated frame motor graders, on the other hand, have both front and back axles, with a hinge connecting the two. This structure gives articulated frame motor graders a much greater degree of maneuverability. However, for jobs with ample space, a rigid frame grader usually suffices.

3. Crawler Loader

While a lot of excavated materials can simply be redistributed around the work site using a grader, certain materials have to be removed entirely. For instance, excessive amounts of rocks or other unwanted materials loosened up during the excavating process. These materials have to be safely conducted to a waste area from which they can later be removed entirely.
Few vehicles accomplish the task of moving worksite materials as well as a crawler loader. These vehicles contain front loading buckets, much like those on a wheeled loader. Instead of wheels, however, a crawler loader utilizes tank-like tracks.
These tracks give the crawler loader a much greater degree of stability, allowing it to easily carry loads across uneven terrain. This maneuverability gives the crawler loader a distinct advantage over not just wheeled loaders, but also over hydraulic excavators. Despite having greater lifting power, hydraulic excavators cannot move on their own, instead having to be towed or transported around the job site.
The world of construction - and in particular, the world of excavation - has greatly benefited from technological developments. To learn more about the kinds of vehicles used on excavation sites today, please contact the pros at Able Hauling & Excavating.
