Key Component Explanations for Heavy Machinery

To help you better understand your equipment, here are some essential component definitions. These parts are critical for the function of your machinery and are part of our extensive parts catalog.

• Drill Hammer / Rock Drill: This component is located at the front of a rock drill machine. It strikes the drill rod, creating a hole in rock or concrete.                
  Example: Sandvik DI550 rock drill hammer parts, Atlas Copco SmartROC D60 rock drill components, Epiroc Boomer L2D drill hammer.                
  Russian: Буровой молоток: Этот компонент расположен в передней части буровой установки. Он ударяет по буровой штанге, создавая отверстие в скале или бетоне. Пример: Запчасти бурового молотка Sandvik DI550, компоненты бурового станка Atlas Copco SmartROC D60, буровой молоток Epiroc Boomer L2D.

• Final Drive / Travel Motor: Located in the undercarriage, this component provides the power to move the machine by rotating the track sprocket.                
  Example: Sandvik DD320S jumbo drill final drive, Atlas Copco HB 3000 hydraulic breaker travel motor, Epiroc MB 1700 rock breaker final drive.                
  Russian: Бортовой редуктор / Ходовой редуктор: Этот компонент расположен в ходовой части и обеспечивает мощность для перемещения машины, вращая ведущую звездочку гусеницы. Пример: Бортовой редуктор буровой установки Sandvik DD320S, ходовой редуктор гидравлического молота Atlas Copco HB 3000, бортовой редуктор скального молота Epiroc MB 1700.

• Swing Motor: Located on the upper structure of the excavator, it's responsible for the rotational movement of the cab and boom.                
  Example: Sandvik LH517 loader swing motor, Atlas Copco Scooptram ST14 swing motor, Epiroc Minetruck MT65 swing motor.                
  Russian: Поворотный двигатель: Расположен на верхней части экскаватора, он отвечает за вращательное движение кабины и стрелы. Пример: Поворотный двигатель погрузчика Sandvik LH517, поворотный двигатель Atlas Copco Scooptram ST14, поворотный двигатель Epiroc Minetruck MT65.

• Hydraulic Cylinder Seal Kit: A collection of seals and gaskets used to repair leaks and maintain pressure within a hydraulic cylinder. Found in booms, buckets, and arms.                
  Example: Sandvik DD421 boom cylinder seal kit, Atlas Copco ECM660 bucket cylinder seal kit, Epiroc MB 1500 hydraulic cylinder seal kit.                
  Russian: Комплект уплотнений гидроцилиндра: Набор уплотнений и прокладок, используемых для устранения утечек и поддержания давления внутри гидроцилиндра. Находится в стрелах, ковшах и рукоятях. Пример: Комплект уплотнений цилиндра стрелы Sandvik DD421, комплект уплотнений цилиндра ковша Atlas Copco ECM660, комплект уплотнений гидроцилиндра Epiroc MB 1500.
