Wheeled excavator Hyundai R140W-9S: technical characteristics and analogues

E140w is a leader among domestic manufacturers

The Hyundai r140w excavator operates on a modern and largely improved engine, which is characterized by a reduced noise level during operation and a lower level of waste emissions into the air. This parameter is especially important today, when the environmental issue in many countries comes first. In addition, the engine is equipped with an electronic monitoring and control system.

Thanks to its technical characteristics, this model can carry out digging work at a depth of about five meters. And our domestic analogue copes with its functions at a depth of almost 6 meters, which gives it a certain advantage over the Korean device. However, it also surpasses it in digging radius - 9.4 m compared to 7.9 m. Thus, the e140w has slightly more powerful characteristics, which are decisive for an excavator. By the way, the overall dimensions and weight of our analogue are smaller, and the performance is greater.

Both models are capable of operating even in unfavorable or difficult weather conditions such as drought or periods of heavy rainfall. The outer casing is protected from corrosion and possible surface damage. Technical characteristics of the r140w 9s ensure high reliability of the unit. For all their productivity, both of these models are not considered large-sized excavators, but rather belong to medium-sized machines.

Hyundai r140w 9s – modern technologies at the service of man

In addition to operational improvements, the internal properties of the excavator have also undergone significant changes. The overall control scheme has been improved. By enlarging the glass on the right side, the overall visibility from the operator's cab has been significantly improved. In addition, all windows are made of safety glass, which is important given the range of operation of this technology. The ergonomic dashboard makes it possible to easily switch operating modes of the unit, which also has a positive effect on overall comfort. For convenience, a heater and air conditioner are built into the operator's cabin. Both presented models, both domestic and foreign, are controlled using a convenient joystick. And most importantly, you don’t have to worry about the operator’s safety during operation. Manufacturers took into account all possible situations and implemented a modern safety control system.

The Hyundai r140w 9s excavator is equipped with another innovative feature. We are talking about a remote control system. This means that you can carry out diagnostics or check the general condition of the machine from absolutely any computer that has free access to the Internet. This significantly reduces costs during device downtime in the event of a breakdown and helps to quickly and timely identify the cause of the failure and the location of the required service intervention. In the domestic analogue, such a function will probably be implemented in the near future.
