Drill Bit: This is the cutting tool at the end of a drilling rig's shank, used to crush or cut rock.            
           Example: Atlas Copco ROC L8 Rock Drill Bit (Атлас Копко ROC L8 Буровое долото / 钻孔工具).

Hydraulic Pump: The heart of a hydraulic system, it converts mechanical power into fluid power. It is installed in the main chassis of excavators and drill rigs.            
           Example: Sandvik DP1500 Hydraulic Main Pump (Sandvik DP1500 液压主泵 / Гидравлический главный насос Sandvik DP1500).

Hydraulic Cylinder: This linear hydraulic actuator is used to push or pull loads. Found on excavator arms, booms, and buckets.            
           Example: Epiroc PowerROC T45 Boom Cylinder (Epiroc PowerROC T45 动臂油缸 / Цилиндр стрелы Epiroc PowerROC T45).

Undercarriage Roller: A wheel-like component that supports the weight of the machine's upper structure and guides the track. Located underneath the track frame.            
           Example: Atlas Copco L6 Carrier Roller (Atlas Copco L6 托链轮 / Поддерживающий каток Atlas Copco L6).

Track Shoe: The individual plates that form the track chain of a tracked vehicle. They are bolted to the track links.            
           Example: Epiroc SmartROC D65 Track Shoe (Epiroc SmartROC D65 履带板 / Башмак гусеницы Epiroc SmartROC D65).

Swing Bearing: A large bearing that allows the upper structure of a machine, like an excavator's cab and boom, to rotate 360 degrees. It is located between the chassis and the upper structure.            
           Example: Sandvik Leopard DI550 Swing Bearing (Sandvik Leopard DI550 回转支承 / Опорно-поворотное устройство Sandvik Leopard DI550).

Drill String: The assembly of drill pipes, collars, and the drill bit that transmits rotational energy and weight to the cutting tool.            
           Example: Atlas Copco FlexiROC T45 Drill String (Atlas Copco FlexiROC T45 钻杆串 / Буровая колонна Atlas Copco FlexiROC T45).

Main Control Valve: This component directs hydraulic fluid to the various cylinders and motors, controlling the machine's movements. Located in the hydraulic system manifold.            
           Example: Sandvik DP1100 Main Control Valve (Sandvik DP1100 主控制阀 / Главный распределительный клапан Sandvik DP1100).

Rotary Actuator: A device that converts hydraulic pressure into rotary motion. It is commonly used for rotating components like the drill head or a gripper.            
           Example: Epiroc PowerROC T35 Rotary Actuator (Epiroc PowerROC T35 回转驱动器 / Поворотный привод Epiroc PowerROC T35).

Transmission: A crucial system that transfers power from the engine to the wheels or tracks. It is located between the engine and the final drive.            
           Example: Atlas Copco ECM660 Transmission (Atlas Copco ECM660 变速箱总成 / Коробка передач Atlas Copco ECM660).
