Using the right equipment is essential for any job in order to get it done safely and efficiently. While it may not seem as if there is much to think about when choosing dump trucks other than capacity, there are actually two types that should be considered. By knowing about each type of vehicle and its best use, it is possible to make wise equipment choices. One thing is sure, which ever truck you need, safety equipment is the same for both, such as the dump lok. Dump lok stands are safety stands that will protect workers while working with the dump truck.
Dump Truck Differences
Technological advances and demand in the construction industry have brought about changes in various equipment over the years and the dump truck is no exception. Before purchasing one, there is now a choice of two types, each of which excels in a different working environment.
Rigid Dump Trucks (RDT) – These vehicles are a standard, one-unit vehicle body and chassis. Most have dual axles in the rear and many have three; those with more than three axles are not usually seen on construction sites because of poor handling ability. Most conventional dump trucks are able to get in and out with loads and are well-suited to drive on roads and highways.
RDT’s typically have the largest load capacity of the two types and can be more efficient for long-term hauling as more can be carried with each trip. The main restriction with rigid trucks is that they are just that – rigid – and unable to be used at sites with greater than 10 degrees of grade or any more difficult driving conditions.
Articulated Dump Trucks (ADT) – These are units with advanced design to handle a more complex work site. They are built with two and three rear axles to support load handling; however, these trucks have an articulated, joined hitch between the cab and the body. This allows them to turn more freely while loaded and to be useful on rough or graded terrain as well as bad weather or mud conditions where a rigid truck could not go.
The cab can be operated up to a 45-degree angle from the body, which allows there to be a remarkably tight turning radius for the vehicle size. With all-wheel drive, they are great for navigating work sites that have heavy mud conditions as well as hills, inclines, and other obstacles to get through.
ADT’s are very maneuverable, which also means they are not built as large when compared to a similar-sized RDT. They are four feet less wide to make it easier to use them; however, it does limit load volume.
