Product Feature

  • Three beams and four columns structure, with good guidance and strong rigidity;
  • The movable crossbeam has a two-stage speed, fast downward movement with no load, slow profiling and fast return travel, and high work efficiency:
  • Side cylinder synchronous control, high product accuracy;
  • Automatic counting function；
  • The main sealing components are imported products, with a long service life;
  • The key electrical components adopt well-known brands from Europe, America, and Japan, with high working reliability;
  • The hydraulic components are selected from internationally renowned brands to ensure good performance;
  • The surface of the column and piston rod are treated with medium frequency and plated with hard chromium;
  • Equipped with infrared protection device for safer operation;
  • PLC control, reliable action;
  • Multiple working modes: the main cylinder has fixed stroke and constant pressure options, while the side cylinder can be used separately, simultaneously, or not.
