A wheeled excavator gives you much of the incredible digging power of a crawler excavator, but with wheels designed to navigate paved roads and parking lots better. That might seem like a minor distinction, but considering many areas have laws forbidding the use of crawler models on a city street, it is an important one. The Hyundai R55W-9A is the smallest of the wheeled excavators available from Hyundai, and is essentially a wheeled version of one of their most popular compact excavators - making it a great option for a wide range of uses.

Here at Quality Fleet Service, we are proud to offer an extensive lineup of different excavators from Hyundai, including crawler, wheeled, and compact models. No matter what kind of excavator you need, we are ready to help you determine which model is right and make sure you have everything you need to get your job done. With our large test pit, you can see how this sort of machinery would work for you, and we offer long-term service and support here at our facility or at your location when necessary. Visit us at Quality Fleet Service and discover the best way to take care of your commercial equipment.

The Hyundai R55W-9A

Wheeled excavators are the perfect solution when you need to do some serious digging, but your machinery has to traverse paved roads and areas that would be damaged by wheeled excavators. The Hyundai R55W-9A is the smallest of the wheeled excavators offered by Hyundai and is a wheeled version of the R55-9A compact excavator, hence its small size and frame. So if you are looking for a wheeled model that you can easily use in areas without a lot of space for the wide swing of a larger model, then this is an ideal choice.

The Hyundai R55W-9A is powered by a Yanmar water-cooled 4-cycle diesel engine that delivers up to 65.1 hp and up to 174 lb-ft of torque, which is excellent for a compact model. Its operating weight is more than 12,000 lbs since it is a smaller excavator, and it has a bucket range of up to 0.18 cu.m. or 0.24 cu.yd. The swing speed on this model is 7.8 rpm, which is a bit less than the standard compact version of it due to its wheeled design.

Those wheels give this excavator a travel speed of up to 18 mph, however, which is substantially faster than the crawler version of this compact excavator. It has a maximum digging reach of just over 20 feet and a maximum digging depth of more than 11 feet, so it can handle pretty diverse terrain. With a tail swing radius of just over 5 feet, it is a great choice for use in tight spaces. Finally, this model has a bucket breakout rating of 9,550 lbs of force and offers more than 7,000 lbs of digging force for getting your work done.

If you are uncertain of exactly which excavator is best for your needs, then we are here to help. Not only are our friendly salespeople incredibly knowledgeable about different excavator models and which one is best for various work situations, but we also have a large test pit. Here at our test pit, you can see different machines that we offer, working in real-world conditions, to get a true sense of which one will best meet your needs. Whether that is a wheeled compact excavator like the Hyundai R55W-9A or any other model we offer, we will make sure you get exactly the right machine.

Long-Term Warranty Protection

Although there are plenty of things to like about Hyundai's powerful commercial machinery, one of our favorite aspects of them is the incredible warranty coverage they include. When you see a great warranty on this type of equipment, it tells you that the manufacturer really stands behind what they do, and they are confident in their work. This lets you rest easy, knowing that your investment in your business is covered.

The Hyundai R55W-9A warranty coverage includes:

  • 3-year or 3,000-hour full machine warranty
  • 5-year or 10,000-hour structural warranty

While the standard warranty is already excellent, Hyundai also offers extended warranties that provide you with up to 5 years or 10,000 hours of full machine coverage. Best of all: you do not have to decide if you want the extended warranty when you buy your equipment. You can choose to get the extended warranty at any time so long as your machinery is still covered by the original warranty.

Hyundai also covers all of its parts with a 1-year or 1,500-hour warranty. Since we are an authorized Hyundai service center, we use Hyundai factory parts whenever possible while working on your machinery. This means that you know our work is covered by not only the original warranty for your equipment, but also by additional protection for the parts we use.
