Komatsu Europe has launched the WB93R-8 backhoe loader, the first model of a new range in line with EU Stage IV emission regulations.

Built around the successful features of previous Komatsu backhoe loaders, the new WB93R-8 has an operating weight of 8,130 kg, and an improved EU Stage IV Komatsu SAA4D99E-1 engine with more power (75 kW /102 hp gross) and lower fuel consumption. A viscous fan clutch helps to achieve fuel savings, and it reduces engine load when maximum cooling is not required. With a selective catalytic reduction (SCR) system using AdBlue, the new after‐treatment system reduces NOx emissions, to offer more protection to the operator and bystanders.

Komatsu’s closed load sensing system is at the core of the WB93R-8’s hydraulics. It is supplemented by power/economy working modes and Komatsu’s exclusive parallel loader linkage, for working with forks. 

The latest Komtrax technology and a new 7’’ multi-function colour monitor, with fuel consumption indications and maintenance info displayed in one of 15 built-in languages, improve communications between the machine and the operator.
