Cylinder overhauling

Regular inspections and the overhauling of all cylinders in a continuous wood-processing plant are necessary to ensure consistent production and plant safety. Worn packings may allow hydraulic oil to escape and therefore expose the plant to serious risk. The infeed cylinders in the areas around Frames 1 to 5 are particularly at risk because this is where the temperature and pressure are highest.



  • increased oil consumption
  • high risk of fire
  • dirt may get into the oil
  • oil contamination and valve clogging
