The 30-tonne HX300L is the third Next Generation crawler model launched by Hyundai in the last year, following on from the larger HX360L and HX400L that were launched at the Bauma trade fair in Munich last spring.
Like those models, the HX300L is powered by a Hyundai diesel engine. It also has Full Electrohydraulic (FEH) controls for improved operator precision and fuel efficiency.
Other highlights include enhanced lifting capacity thanks to extra counterweight and 325mm (12.8-inch) touchscreen monitors.
Weighing 31,820kg, the machine is powered by Hyundai’s DX08 six-cylinder diesel engine, delivering 207kW (277hp), an increase of 9% versus the previous 30-tonne A-Series machine, along with 1,230Nm of torque.
In combination with EPOS (Electric Power Optimising System) hydraulic control, the engine consumes up to 7% less fuel than in the previous machine, the Korean manufacturer says, and 30% less AdBlue. Customers should also see a reduction in service costs, as oil and filter change intervals have been doubled – to 1,000 hours.
As with the larger models, the HX300L has Hyundai’s Full Electrohydraulic (FEH) hydraulic system. This includes electric joysticks, that communicate by wire with the valve block. This eliminates hydraulic loss through pilot controls and offers operators the opportunity to fine tune individual hydraulic functions to their exact requirements. They can adjust the sensitivity and response of the levers to their own preference, settings that can be memorised within the system to that operator’s key.
Smart technologies in the Next Generation excavators include optional 2D machine guidance and control – with bucket, slew and grade assist – with the ability to upgrade to a 3D system. The machines can have an automatic weighing function, allowing operators to load trucks and deliver production data.
Safety features include Lift Assist and Advanced Lift Assist, providing visual safety zones for lifting operations. The Next Generation excavators also come with an e-boundary function, allowing the operator to set ceiling, floor and wall limits to prevent collisions and improve site safety.
These can be used in conjunction with the upgraded Smart Around View Monitor (SAVM) system, which now comes with six cameras mounted around the machine incorporating an AI-based human detection and recognition system. In addition, Radar Object detection alerts the operator to nearby hazards with visual and audible warnings. An automatic stop function can halt the machine’s movements if the operator ignores the audible warnings. For other site operatives, the Next Generation models have four-corner beacons on the cab roof, ensuring that the lights can be seen from any direction. There is also an external microphone that allows the operator to communicate with other site personnel.
Inside the cab, a digital key option allows operators to enter and start the machine from their smartphone, a feature that can be shared with up to six operatives and transport drivers. Premium seating, multi-channel infotainment and luxury cab matting are all offered.
The HX300L has an 11% longer track length, now 4,040mm, and a 6% heavier counterweight. This combination results in improved lifting capacity over the front and the side of the machine. The standard monoboom is 6,245mm long, with a 3,100mm dipper arm. This provides a dipper tear-out force of 141kN and a bucket tear-out of 206kN.
The machine will be offered in three build configurations: the standard HX300L, a narrow track HX300NL and a long-reach HX300LR.
