Hyundai has announced the arrival of three new excavators in one of the most popular weight classes, the HX130 A LCR, HX140 A LCR and the HX145 A LCR. Ranging from 13 to 15 metric tons, all three are Stage V emissions compliant and available in the U.S. and Europe.
This HX A series excavators have several new elements in common. First, the Cummins engines have been designed for 1,000-hour oil-change intervals, twice as long as the previous models, when using CK-4 E/G lube oils.
The HX A Series machines also offer an upgraded IPC system and adjust the pump-flow rate and power to meet operator demand. The optimized main control valve and the hydraulic pipe layout minimize energy loss throughout the system.
For finesse, a new lifting mode improves fine control and lift capability, reducing engine rpm, activating power boost and offering improved pump flow control. The excavators also offer an optional fine swing control that smooths the movement of the boom at the start and stop of the swing.
The operator can change the ratio between the boom-lift speed and swing speed by activating and deactivating the boom priority function. Dipper arm speed can be fine-tuned by activating and deactivating the arm regeneration function. You can save these settings for repeatable performance in frequently performed tasks.
Cabin space in the three machines has been increased by 13%. They feature an improved grab handle design in the cabin door, making it easier to access the driver’s seat and improving visibility to the side from the cab.
The excavators have a modern cab interior with an 8-inch capacitive-type touchscreen for all major information, which can also be controlled through an automotive-style jog/dial module.
