HD Hyundai reveals eight new mini excavators

HD Hyundai has unveiled an additional eight mini excavators for the European market, with operating weights of 1.7 to 5.5 tonnes

HD Hyundai says its new A-Series machines deliver reduced emissions, increased hydraulic capabilities and improved operator comfort.

The new compact excavators join existing HD Hyundai mini and midi crawler machines, to form a 12-model range, from the 1.0-tonne HX10A micro through to the nine-tonne segment HX85A.

Five of the mini excavators: the HX17A Z, HX19A, HX35A Z, HX40A and the HX48A Z have been launched, with 2.5-tonne, three-tonne and five-tonne models completing the line-up in the second quarter of 2024.

While all models feature compact dimensions, those with a ‘z’ suffix have a zero-tailswing design, allowing the machines to work up against walls and other obstructions without risk of striking the bodywork. The zero tailswing machines can be supplied with additional counterweight if required, to increase stability during heavy lifting operations. Variable-width undercarriages on the smaller models also deliver maximum stability for heavy digging and lifting tasks, says HD Hyundai.

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

In the cab an improved air conditioning system is available on larger machines and noise levels have been reduced internally and externally. The cab has Bluetooth connectivity and the machines come with a waterproof 5” digital display. As well as providing operating data, this monitor can be used to program auxiliary hydraulic flow settings for a range of powered attachments. The screen is also used to set the anti-theft protection code.

The machines use hydraulic joysticks, similar to those found on larger A-Series excavators. Proportional roller switches can be supplied in the joystick heads, for optional auxiliary flow control. All models from the HX40A are now equipped as standard with a load-sensing hydraulic system, delivering smooth but powerful and precise control. A single variable displacement pump with flow sharing capabilities provides for smooth combined use of multiple hydraulic functions, making the machines easy to control for fine digging and grading work. Hydraulic components have been repositioned, with the main control valve now installed on the right of the machine, for service convenience.

Large rear and side engine compartment doors provide easy access to all regular service points, with heavier models offered with a tiltable cab. All filters and fill points can be reached from ground level and there is a lower chassis connection interface for the dozer cylinder hoses, to facilitate replacement.

HX-A Series mini and midi excavators can be supplied with HD Hyundai’s Hi Mate remote management system. This uses GPS satellite technology to provide real-time telematic operating data to machine owners and service departments.
