HYUNDAI Construction Equipment is launching the compact radius HW150A CR wheeled excavator.
Following the introduction of the larger HW170A CR, the manufacturer said the latest model promises to become the ‘flagship’ of the A-Series range. Hyundai said the machine has been unveiled in response to growing demand for a more utility and service oriented wheeled machine in the 15-17 tonne segment.
Features include a Stage V-compliant Cummins B4.5 diesel engine requiring no EGR; load sensing hydraulic system delivering load independent flow control; repositioned upperstructure contributing to shorter slew radius; and increased lifting capacity and improved stability.
The HW150A CR joins the HW140A, HW160A and the compact radius HW170A CR in the Hyundai line-up. The larger HW210A sits in a class above.
This 4.5-litre engine uses a wastegate turbocharger and 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 regulations.
The engine drives a Bosch Rexoth load sensing hydraulic system and a fully hydrostatic, four-wheel drive powertrain. Hyundai explained the load sensing system allows load independent flow control, which makes it easier to work boom, dipper arm, bucket and slew function simultaneously.
As with the other models in the A-Series range, the upperstructure has been repositioned on the lower chassis, contributing to a reduced tailswing. A new swing bearing design is said to offer improved stability and durability, while new, 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.
The HW150A CR features an automatic digging brake, that locks the front axle oscillation and the service brake, allowing the operator to start work as soon as the machine stops travelling.
Customers can specify the lower chassis layout of the machine to suit specific needs. The lower attachments, including dozer blade and front and rear outriggers, are interchangeable.
A revised front attachment design has the dipper arm hydraulic cylinder reversed to provide increased protection of the ram, Hyundai added. The machine can be delivered with a choice of monoboom or two-piece design.
The cab features increased glazing on the door and roof hatch, while the upper and lower windscreen glass comes with larger, parallel wipers. An 8” touchscreen display provides access to all machine functions and controls settings.
Despite its compact radius dimensions, the engine cover size has been reduced, to improve visibility to the rear of the machine. Wheeled A-Series models feature Hyundai’s Advanced Around View Monitoring (AAVM) system, that uses cameras to provide the operator with a 360° view of the machine on the in-cab monitor. The system includes Intelligent Moving Object Detection (IMOD), alerting the presence of other workers or objects within a 5m range.
Proportional joystick controls are standard and joystick steering with directional control can be specified as an option.
A revised pedal layout and improved floor mat are said to make it easier to clean the cab floor. Forward, neutral and reverse can be accessed through a switch on the servo lever, rather than through an additional pedal.
Peter Sebold, product manager at Hyundai Construction Equipment Europe, said, “The all new HW150A CR is born from the requirements of urban job sites. Its rear short radius allows for top manoeuvrability as well as for operator convenience and safety.
“We made the choice of using components and systems from reputable suppliers, which already pays off in terms of performance and durability. The powerful engine, in combination with load sensing hydraulics, gives the machine smooth controllability, along with high performance, as well as an enhanced versatility. A wheeled excavator just the way you want it. No frills, easy to handle and thoroughly robust.”
