Compact wheeled excavator

May 18, 2022

This 4.5-litre engine uses a wastegate turbocharger and a proven Flex Module after-treatment system. This two-can exhaust system brings together a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) to meet EU Stage V emissions regulations. There is no requirement for exhaust gas recirculation (EGR) and the engine has no requirement for manual DPF regeneration. A reversible cooling fan is available for dusty working environments. The engine drives a Bosch Rexoth load sensing hydraulic system and a fully hydrostatic, four-wheel drive powertrain. The load sensing system allows load independent flow control, which makes it easier for the operator to work boom, dipper arm, bucket and slew function simultaneously. This improves controllability and boosts productivity, while reducing fuel use and cutting emissions, Hyundai says.

Following the launch of the larger HW170A CR, the HW150A CR promises to become the flagship of the A-Series wheeled excavator range, according to Hyundai. Sitting in the 15-17 tonne segment, it is designed to satisfy the growing demand for a more utility- and service-oriented wheeled machine. The 1800mm swing radius allows the machine to work within confined job sites.

As with the other models in the A-Series range, the upperstructure has been repositioned on the lower chassis, contributing to a reduced tailswing while increasing stability during travel. It also improves lifting and digging capabilities. A new swing bearing design offers improved stability and durability, while lighter mud guards cover the whole wheel, turning with the wheel when steering. Safety valves are available on the ram lock cylinders on the front, steering axle.
