Hyundai expands mini excavator range

Hyundai has unveiled a new batch of mini excavator models with operating weights of 1.7 to 5.5-tonnes.

The new compact excavators join existing HD Hyundai mini and midi crawler machines to form a 12-model range, from the 1-tonne HX10A micro to the 9-tonne HX85A. Five of the mini excavators—the HX17A Z, HX19A, HX35A Z, HX40A, and the HX48A Z—have launched recently. The 2.5-tonne, 3.0-tonne, and 5.0-tonne models will follow in the second quarter of 2024.

HD Hyundai Construction Equipment Europe says that its A-Series machines “set new levels of performance and productivity, delivering reduced emissions, increased hydraulic capabilities and improved operator comfort”.While all models feature compact dimensions, those with a ‘z’ suffix have a zero-tail swing design and can be supplied with additional counterweight if required to increase stability during heavy lifting operations. Hyundai says that variable-width undercarriages on the smaller models also deliver maximum stability for heavy digging and lifting tasks.

Safety valves are standard on all boom, dipper arm and dozer blade hydraulic cylinders. The boom arm and bucket cylinders also come with guards to protect hydraulic rams. All machines can be supplied with optional quick-coupler piping. A float function is now included in the dozer blade hydraulics, while an optional angle blade is available on HX35A Z and above.

Inside the cab, an improved air conditioning system is available on larger machines as an option, and noise levels have been reduced internally and externally. The cab has Bluetooth connectivity, and the machines come with a waterproof five-inch digital display. In addition to providing operating data, this monitor can be used to programme auxiliary hydraulic flow settings for a range of powered attachments. The screen is also used to set the anti-theft protection code.

All these machines use hydraulic joysticks similar to those found on larger A-Series excavators. For optional auxiliary flow control, proportional roller switches can be supplied in the joystick heads.

Hydraulic components have been repositioned, and the main control valve is now installed on the right of the machine for service convenience.
