Rough terrain (RT) cranes are a staple at countless job sites. These types of cranes are the choice of many industries since they are capable of handling a variety of tasks. Unlike some other cranes, these versatile cranes provide reliable service in rugged terrains without compromising on power and dependability.

Advantages of Rough Terrain Cranes 

A number of design advantages make these handy cranes capable of maneuvering over surfaces and around obstacles that may limit the movement of rubber-tire truck cranes and crawler cranes. Rather than three or more axles (like most rubber-tire truck cranes have), typical rough terrain cranes have two hyper-sized axles. Both axles will have a differential to propel the wheels, which means they can be 4-wheel drive. In addition, 4-wheel steering gives them excellent handling that makes them able to access many areas of the job site that other types of cranes may not.

Their bases as well as their tires are wider for added stability. Rough terrain cranes have over-sized tires, which are significantly wider and larger in diameter than those found on a typical radial-tire truck crane. These tires are taller for added ground clearance over rugged terrain. Rough terrain cranes are generally lighter than all-terrain truck cranes since they are driven and controlled by a single operator’s cab and have a single engine that gives power to both the undercarriage and the superstructure. However, they cannot travel at high speeds like all-terrain truck cranes, so they must be transported to job sites. Otherwise, they can be much quicker and more controlled than crawler cranes as they can navigate tight corners and move better over rocky environments.

Determine Your Goals

The first point to consider is obviously the weight of the load that needs to be lifted or moved. You need to know the net capacity the crane offers to be able to successfully lift the load. You also need to determine the height that the boom needs to lift the load and the distance the load needs to be moved. These are good starting points to begin narrowing down your choices. Sourcing a lower capacity crane that is not up to the job will limit the work it can do and potentially lead to the unsafe practice of overextending the crane’s capabilities. This can lead to accidents as well as damage to the load. On the other hand, getting a crane that has a lot more capabilities than is needed may cost more than you need to spend. However, it is a good practice to choose a crane model that has a little extra lifting ability than is required, so it can handle any unforeseen load weight increases.

Understand the Job Site

The ground the crane needs to operate on is a big factor and should be evaluated. The crane needs to be able to navigate the terrain of the site and work from a solid foundation. You also need to determine how adaptable the crane should be for your job site. This can be affected by the tire size, suspension system, and drive modes of the crane. Rough terrain cranes generally operate well in uneven environments that are common on construction sites as they also have outriggers that can provide added support and a level platform to lift and move loads safely.

The weather and environmental conditions at the job site are additional factors. The potential for high winds, rain, snow, ice, extreme cold, or extreme heat should be considered. Muddy or slippery terrain can cause difficult working conditions for some models. Some adverse conditions may be too extreme for any type of crane to operate safely. So, choosing the right rough terrain crane is very important for many rugged off-road type sites.

Makes and Models

There are a lot of different makes and models available to choose from when selecting a rough terrain crane. Capacities generally available range from 15 tons (such as the Tadano GR-150XL) up to 160 tons (such as the Tadano GR-1600XL). Boom lengths can vary from approximately 78’ up to 200’ based on the model (with their jibs offering additional length and height). Once you determine the lifting capacity, lift radius, and boom length that you need for the job, there are a number of high-quality manufacturers to choose from such as Tadano, Broderson, Kobelco, Grove, Manitex, Link-Belt, and Liebherr.

Advanced Technology

Rough terrain crane technologies continue to become more and more advanced. Many of the newer models offer features that make the work much easier and safer for operators. Tadano’s AML-C (Automatic Moment Limiter) load moment indicator systems are very popular that display the boom angle, boom length, load radius, rated lifting capacity, and other key details. It can also allow the operator to preset a custom working environment without having to change any configurations or input new codes to make a lift. These useful systems also detect the extension width of the outriggers at all four corners to offer maximum area work value. Some cranes also offer a smart counterweight system that is self-removable. This, along with compact carrier lengths, allow some cranes to be transported fairly easily.

Many Tadano models come with Tadano’s “Smart Chart” technology to expand the operator’s working area and provide enhanced performance in any outrigger setup to help maximize work performance at the job site. They also come with Hello-Net telematics systems that support crane management by providing details on operational status, position, and maintenance, as well as work history such as daily or monthly mileage and hours of operation. Tadano’s Eco-mode system controls the maximum engine speed, reducing fuel consumption and noise while providing solid crane operation.

Renting or Buying

The budget you are working with can make an important difference on the crane you ultimately choose. This can also determine whether you rent or buy a crane. The circumstances of the job additionally play a major role. If the amount of work is small and short term, renting a crane is usually the best option. However, if a crane is going to be needed for similar projects over a longer term or indefinitely, buying a crane may be more cost effective over the long run.

New Versus Used Cranes

Making the choice of buying a new or a used rough terrain crane is also important. There are advantages for both that you must consider. Used cranes offer significant cost savings compared to new ones, making them a good choice for budget-conscious buyers. You can maximize your investment while still acquiring reliable lifting solutions. A new crane is going to cost more, but it is going to perform well and last longer with less need for upkeep in the near future. You can also gain peace of mind with the manufacturer’s warranty accompanying your new crane, ensuring reliability and support. New cranes also keep you at the forefront of technology with the latest features, functionality, and safety measures.

Conclusion

Choosing the right type of crane for the job can be a major factor in whether or not a project is completed successfully. Rough terrain cranes are widely used throughout many different industries due to all their advantages. When choosing a rough terrain crane, it is also important to work with a reputable company.
