Glossary of Common Engineering Machinery Parts

To help you better understand your machinery, here are some key terms for construction equipment components:

• Final Drive: The hydraulic motor and gearbox located on the machine's undercarriage that converts hydraulic pressure into rotational force to move the tracks. For example: Sandvik DP1500 Final Drive, Atlas Copco L8 Final Drive, Epiroc PV271 Final Drive.

• Swing Motor: The hydraulic motor that rotates the machine's upper structure (cabin, boom, etc.) on the swing bearing. For example: Sandvik DX800 Swing Motor, Atlas Copco PowerROC T45 Swing Motor, Epiroc HB4700 Swing Motor.

• Track Roller: A wheel on the undercarriage that supports the weight of the machine and guides the track chain. For example: Sandvik Dino 1000 Track Roller, Atlas Copco DM45 Track Roller, Epiroc SmartROC D65 Track Roller.

• Hydraulic Cylinder: A linear actuator used to push or pull a load, consisting of a cylinder barrel, piston, and rod. For example: Sandvik D520 Hydraulic Cylinder, Atlas Copco FlexiROC T40 Hydraulic Cylinder, Epiroc HB4200 Hydraulic Cylinder.

• Rock Drill: The component at the end of a boom used to percussively drill into rock. For example: Sandvik DP1500 Rock Drill, Atlas Copco DM30 Rock Drill, Epiroc SmartROC C50 Rock Drill.

• Sprocket: The toothed wheel on the final drive that engages with the track chain to propel the machine. For example: Sandvik DI550 Sprocket, Atlas Copco DM25 Sprocket, Epiroc SmartROC C50 Sprocket.

• Idler: A wheel on the undercarriage that provides tension to the track chain and guides it. For example: Sandvik DI550 Idler, Atlas Copco T40 Idler, Epiroc HB4700 Idler.

• Control Valve: A device that directs the flow of hydraulic fluid to various components. For example: Sandvik DI550 Control Valve, Atlas Copco SmartROC D65 Control Valve, Epiroc HB3000 Control Valve.

• Engine Filter: A component that cleans the oil, fuel, or air used by the engine. For example: Sandvik DP1500 Engine Filter, Atlas Copco PowerROC T35 Engine Filter, Epiroc SmartROC D65 Engine Filter.

• Pump Assembly: A complete unit consisting of a pump and its associated components, used to pressurize fluid. For example: Sandvik DI550 Pump Assembly, Atlas Copco DM45 Pump Assembly, Epiroc SmartROC D65 Pump Assembly.
