LIEBHERR crawler crane Undercarriage parts

Quality Materials

With advanced CNC machine tools, paint spraying lines meeting environmental protection standards, and professional quality inspection laboratories, the high-standard management mold room, casting and forging workshop, heat treatment workshop, and finishing workshop create a high-efficiency production line.

Experienced Team

With parts manuals, drawings, and original production process standards, a professional technical team assures high-precision dimensions. Furthermore, our engineers make drawings and CAD models to help customers realize customized services.

Strict quality inspection

Each crawler crane chassis has a traceable production batch number, and a quality inspection department performs material inspection, mechanical performance inspection, hardness inspection, tensile inspection, destructive inspection, size inspection, etc. Tracked chassis parts undergo 7+ quality inspections before leaving the factory. Customers can also request third-party quality inspections and inspection reports.

  • The shape is made of sand according to the mold
  • Pour the molten steel into the sand mold (first analyze the chemical composition of the furnace before the spectrometer)
  • The mechanical properties of the track shoe after heat treatment, usually using CSS44300 universal tensile testing machine
  • Surface cleaning refers to steam-cutting wind gun gates, risers, and sand cleaning sand cores with windguns
  • Normalizing is mainly to eliminate internal stress and reduce the hardness of the workpiece.
  • Surface treatment refers to the sharp corners, burrs, etc. remaining on the surface after the work workpiecepiece is normalized.
  • Quenching and tempering are mainly to improve the comprehensive mechanical properties of the workpiece
  • Shot blasting refers to the shot blasting after the workpiece is quenched and tempered to achieve a smooth surface.
  • The contact position between the track shoe and the wheel body tread and the intermediate stage quenching treatment at the boss
  • Processing according to the drawings
  • Grinding is to polish the track shoes after quenching or quenching, and the smoothing needs to be smoothed.
  • Check whether the polished track shoes are qualified again.
  • Qualified track shoes to be painted.
  • The product is packed and stored in the warehouse.
