Hyundai Hydraulic Excavator

The D suffix, by contrast, marks a wheeled excavator instead of a crawler machine, as seen in this bucket's R110D-7. After the number comes the generation tag: the digit 7 marks a particular excavator generation, and the trailing A on models like R450-7A, per an industry source, denotes adaptation to a stricter emissions standard within the same generation.

The "Hyundai Hydraulic Excavator" bucket spans smaller site machines like the R110-7 up to heavyweights like the R450-7A, and across its 56 active models covers 62 to 365 kW of engine power, 11,200 to 82,320 kg operating weight, 4- to 6-cylinder engines, and torque from 371 to 2364 Nm.

Buying used, LC models are worth checking for wider track shoes and pads, which wear unevenly under intensive digging, along with the seals on the dipper and boom cylinders.
