YANMAR EXCAVATOR vio50-2 vs vio50-6: What's the Difference?

YANMAR, a leading manufacturer of excavators, offers a range of models that cater to the specific needs of the construction industry. Two such models are the vio50-2 and vio50-6 excavators. Both are popular options among industry professionals, but they do have some differences that set them apart.

Firstly, the vio50-2 is a slightly older model compared to the vio50-6 and was first released in 2005. That being said, YANMAR has made significant improvements to both models since their initial release. The vio50-6 was introduced in 2010 and is marketed as an updated version of the vio50-2.

One of the main differences between the two models is their operating weight. The vio50-2 has an operating weight of 5,005 kg, while the vio50-6 is slightly heavier at 4,965 kg. However, both models offer a digging depth of 3,740 mm and a dumping height of 2,650 mm.

Another key difference between the two models is the engine size. The vio50-2 is equipped with a YANMAR 4TNV88 engine that delivers 39.8 horsepower, while the vio50-6 boasts a more powerful YANMAR 4TNV88C engine that delivers 47.6 horsepower. This increase in horsepower results in improved performance, making the vio50-6 a great option for those looking for a more powerful excavator.

The hydraulic system is also different on the two models. The vio50-6 features a more advanced hydraulic system, with a maximum oil flow rate of 105 liters per minute compared to the vio50-2's maximum of 88.2 liters per minute. The advanced hydraulic system on the vio50-6 allows for smoother and more precise movements of the excavator.

In terms of comfort and safety features, both models are well-equipped. The cabs on both models are designed with ergonomics in mind and come with a variety of features such as air conditioning and adjustable seats. The vio50-6 does have a slight advantage in terms of safety features, as it comes with an anti-restart system that prevents accidental engine start-up.

Overall, both the vio50-2 and vio50-6 are impressive excavators that cater to the specific needs of the construction industry. The vio50-6 is a more advanced model that boasts a more powerful engine and hydraulic system. However, the vio50-2 is still a great option and has been tried and tested by industry professionals for over a decade. Ultimately, the choice between the two models will depend on the specific needs of the user.
