Understanding Key Components in Heavy Machinery

We believe in not just supplying parts, but also helping our customers understand the equipment they work with. Here are some key parts found in heavy machinery:

• Sandvik DD321: Shank Adapter / Хвостовик / 钎尾

  The shank adapter connects the rock drill to the drill string. It transfers the percussive and rotational energy from the hydraulic drifter to the drill rod.
• Atlas Copco L8: Hammer Piston / поршень перфоратора / 锤体活塞

  The hammer piston is a crucial part of the hydraulic rock drill. It strikes the shank adapter, generating the percussive energy necessary for rock penetration.
• Epiroc Smartroc D65: Rotary Head / Поворотная головка / 回转头

  The rotary head is responsible for the rotation of the drill string. It applies torque to the drill rod, which is essential for drilling through various rock formations.
• Caterpillar D6: Track Chain / Гусеничная цепь / 履带链

  The track chain is a component of the undercarriage system on a track-type machine like a bulldozer or excavator. It provides traction and supports the machine's weight.
• Cummins QSK19: Cylinder Liner / Гильза цилиндра / 缸套

  The cylinder liner is a cylindrical part installed inside the engine block. It forms the combustion chamber and guides the piston's motion.
• Komatsu PC200-8: Hydraulic Cylinder Seal Kit / Комплект уплотнений гидравлического цилиндра / 液压缸密封件

  A seal kit is a collection of seals and O-rings used to prevent fluid leakage from a hydraulic cylinder, ensuring proper function and pressure retention.
• Hitachi EX1200: Hydraulic Pump Piston / Поршень гидравлического насоса / 液压泵活塞

  The piston in a hydraulic pump moves back and forth to draw in and expel hydraulic fluid, creating the pressure needed to operate the machine's functions.
• Volvo A40G: Axle Shaft / Вал моста / 桥轴

  An axle shaft connects the differential to the wheels, transferring power and torque from the engine to the wheels to drive the vehicle.
• Liebherr PR 736: Final Drive / Бортовой редуктор / 终传动

  The final drive is a reduction gear unit that slows down the output from the transmission and transfers power to the track sprocket.
• Hyundai HX220: Hydraulic Motor / Гидравлический мотор / 液压马达

  A hydraulic motor converts hydraulic energy into mechanical energy, providing rotational power to components such as the swing mechanism or travel drive.
