HYUNDAI is expanding its Next Generation crawler excavator range with a new 30-tonne offering.
The HX300L, like the larger HX360L and HX400L models, is powered by Hyundai’s DX08 six-cylinder diesel engine. The Stage V-compliant powerplant delivers 207kW, which Hyundai said is 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 is said to consume up to 7% less fuel than in the previous machine and 30% less AdBlue. Oil and filter change intervals have been doubled to 1,000 hours.
Weighing 31,820kg, the HX300L features Hyundai’s Full Electrohydraulic (FEH) hydraulic system. This includes electric joysticks that communicate by wire with the valve block. This is designed to eliminate hydraulic loss through pilot controls and gives operators the chance to fine tune individual functions to their exact requirements.
The Next Generation excavators incorporate smart technologies, including optional 2D machine guidance and control, with bucket, slew and grade assist, with the ability to upgrade to a 3D system. The machines can also have an automatic weighing function.
Lift Assist and Advanced Lift Assist provide visual safety zones for lifting operations. The excavators also come with an E-Boundary function, allowing operators to set ceiling, floor, and wall limits.
These can be used in conjunction with the upgraded Smart Around View Monitor (SAVM) system, which 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 hazards with visual and audible warnings, while an automatic stop function can halt movements if the operator ignores the audible warnings.
For other site operatives, the new models have four-corner beacons on the cab roof, ensuring lights can be seen from any direction. There is also an external microphone that allows the operator to communicate with site personnel.
The cab features one or an optional two 12.8” full HD touchscreen monitors. 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 offered in a Comfort Pack. The internal noise level is 68dB(A), which Hyundai revealed is one of the quietest cabs in this size class.
The HX300L has an 11% longer track length (4,040mm) and a 6% heavier counterweight. The standard mono-boom is 6,245mm-long, with a 3,100mm dipper arm. This provides a dipper tearout force of 141kN and a bucket tearout of 206kN.
The machine will be offered in three build configurations: the standard HX300L, a narrow track HX300NL, and a long-reach HX300LR.
