30-tonne addition to Hyundai's A series

The new HX300AL is a 30-tonne Stage V-compliant crawler excavator from Hyundai Construction Equipment.

The HX300AL (pictured above) is bigger brother to the 22-tonne HX220AL announced by Hyundai Construction Equipment Europe just a few weeks ago, continuing the roll-out of the Korean manufacturer’s new A-series.

Hyundai describes the machines as ‘bringing in a new era’, with a Stage V engine, new hydraulic flow regulation, improved operator controls with 2D/3D machine guidance, new safety features and improved uptime and productivity.

The Electric Pump Independent Control feature (or EPIC) controls the pump’s regulation independently for improved fuel efficiency and controllability. The Auto Safety Lock prevents unintended operation/start of the excavator. Eco guidance indicates ‘inefficient operation’ status to prevent wasted fuel or hydraulic power.

Then there is Machine Guidance / Machine Control (MG/MC), which indicates the work status and automatically controls the attachment to assist the driver. MG displays the position of the bucket tip and uses positioning guidance to help the operator. MC will automatically take over the grading with the bucket tip or face and has an automatic stop control: up, down, forward, and cabin protection.

The Cummins B6.7 engine has an all-in-one exhaust after-treatment system, integrating the diesel oxidation catalyst (DOC), the DEF injector (SCR) and diesel particulate filter (DPF). This removes the need for any exhaust gas recirculation (EGR).  Hyundai says that this results in ‘a de-complexed, powerful, and environment-friendly solution’.

Hyundai Construction Equipment Europe product specialist Peter Sebold says: “One of the standout features of the new HX series is named EPIC, and rightly so. The new Electric Pump Independent Control is an energy-saving technology that reduces the pump flow rate during levelling and truck loading operation by controlling the pump’s displacement individually. Think next-level load sensing, fuel saving of up to 8% daily average and general all-round operator and owner satisfaction, that’s just another win for this highly anticipated machine.”

The HX300AL is available in L version, NL version, High Walker version with optional monoboom, 2-piece boom and long reach configuration.
