The big yellow one in the diabase
The armored 3.5 m3 bucket was bought in a package deal together with the excavator and withstands the highly abrasive material perfectly. Nils Bohländer operates “the beast”. He explains: “We saw the excavator at the steinexpo and had it demonstrated to us. I was impressed by the steel structure of carriage and boom of the upper/lower carriage as well as the sensitive hydraulics.” The quarry equipment is rounded off by 600-mm-triple grouser shoes, cylinder protection for piston rods, front protection grille and central lubrication.
The decisive factor for the purchase was the desire for a more powerful loader with a longer reach. The monoblock and 3.40 m stick now perfectly meet the requirements of Bau-Rec Bohländer GbR.

On the 8-inch touchscreen, the operator has the option of setting numerous parameters in intuitive menu items. In addition to displays and switches, many settings can be conveniently adjusted using sliders that can be displayed. There are also 18 conventional buttons below the display for activating central lubrication, idle speed, working lights, etc.
Four working modes ECO, Standard, Power and User (freely programmable by the operator) are stored in the control system and can be selected at the touch of a button. The oil quantity and pressure of up to 20 attachments can be stored in a library. The EPPR function (EPPR stands for Electronic Proportional Pressure Reduce Valve) can be used to increase the hydraulic delivery rate for power-hungry attachments by interconnecting two pumps – this configuration data is also stored in the HD Hyundai system together with the pressure and oil delivery quantity. A feature that is particularly important in demolition. Here, the operator is constantly switching between hammer, shears, pulverizer, sorting bucket, etc.
Safety is a high priority for HD Hyundai products. This is why the reversing camera comes as standard. As an option, HD Hyundai offers the AAVM (Advanced Around View Monitoring) system: Here, a 360° all-round view appears on the display, composed of image information from four cameras. The IMOD (Intelligent Moving Objects Detection) monitoring system detects objects moving around the excavator and visualizes them on the touchscreen.
HD Hyundai now manufactures many components such as travel and swing motors itself, which results in improved integration into the hydraulic system.
