Hyundai Construction Equipment Europe launch first new models in their ‘Next-Generation’ crawler excavator line-up – the 40-tonne HX400L and 36-tonne HX360L – designed to maximize productivity, safety, and operator comfort on every job site

Hyundai Construction Equipment Europe (HCEE) have introduced the first models in their Next Generation crawler excavator range – the HX400L and HX360L. Powered by Hyundai’s award-winning DX08 diesel engine, the new machines combine power, precision, and advanced technology to deliver higher productivity, improved fuel efficiency, and enhanced operator safety.

Featuring full electro-hydraulic (FEH) controls, optional bucket weighing, and the new SAVM intelligent camera system with radar-assisted E-Stop, the HX360L and HX400L also set new standards in performance and safety.

The six-cylinder Hyundai DX08 engine is a clean-sheet design producing up to 341hp (254kW) and 1,460Nm of torque. A two-stage turbocharger provides 23% more power than previous-generation engines, with durability ensured through robust construction. The EU Stage V/Tier 4F engine is built using high-strength, wear-resistant materials across all major drivetrain components.

The result is greater performance, improved economy, and lower operating costs. And the engine achieves an 8% fuel efficiency gain over previous designs. The Next Generation excavators feature a completely new design, incorporating improved Rexroth hydraulic pumps and Hyundai’s own swing and travel motors.

Both models feature full electro-hydraulic (FEH) controls, and when combined with the EPOS (Electronic Pump Optimising System), provide precise management of hydraulic output for greater responsiveness and fuel savings.

The machines are configured for 2.3m3 buckets on a 2.9m dipper arm. The HX400L features a heavier 7.4-tonne counterweight – 1,000kg more than before – to enhance stability and balance the increased front-end performance. A straight boom option is also available for the first time, catering specifically to demolition applications.

The Next Generation cab raises standards in comfort and control. Premium leather seating with heating and cooling is available, alongside dual 12.8in HD monitors. The electro-hydraulic levers and pedals allow operators to fine-tune every hydraulic function’s speed and response.

The FEH system electronically controls oil flow and pressure, eliminating back pressure and energy loss to achieve up to 8% greater fuel efficiency than hydraulic servo systems. Travel can be controlled by a single pedal to reduce fatigue, while either joystick can be configured for steering in forward or reverse travel.

A digital key option allows keyless entry and engine start via smartphone. Other available options include an on-board weighing system that calculates bucket payload, improving truck loading accuracy. Operators can also manage 2D machine control, guidance systems, and a ‘Virtual Wall’ setting from the joysticks for safer, more efficient operation.

A Lift Assist feature provides real-time load maps showing safe operating zones. The Advanced Lift Assist function divides the working area into eight zones for increased accuracy.

Inside the redesigned cab, operators benefit from customizable electro-hydraulic controls and optional smart features such as digital key entry and 2D machine guidance

Increased safety

Hyundai’s AAVM (Advanced Around View Monitoring) system has been upgraded to SAVM (Smart Around View Monitoring), featuring six cameras – including three embedded into the counterweight. With AI-driven human detection, the system highlights personnel in the working area on screen for enhanced safety.

The HX400L and HX360L machines are also equipped with a radar object warning system, with three wide-angle radars that detect people and objects, triggering visual and audible alerts. An E-Stop function automatically decelerates and halts the machine if warnings are ignored. Four-corner beacons, six LED working lights, cab roof guards, and an external microphone further enhance on-site awareness and visibility.

Large access panels make routine maintenance easy. Oil and fuel filter intervals have doubled from 500h to 1,000h, coolant changes extend to 6,000h, and DPF cleaning to 8,000h – significantly reducing downtime. A reversible cooling fan clears radiators efficiently, ideal for dusty environments.

Equipment Health Management (EHM) technology offers real-time condition monitoring to predict potential maintenance issues before failure. Hyundai’s Hi MATE telematics system comes as standard, providing usage data, maintenance alerts, and theft protection.

The HX400L and HX360L excavators mark the beginning of a full crawler excavator redesign for Hyundai. Rather than incremental updates, the company has taken a clean-sheet approach, integrating an in-house engine and hydraulic systems, increasing structural durability, and advanced operator technologies. This new generation of machines sets a higher benchmark for productivity, efficiency, and control in the tracked excavator market.
