Hydraulic machine of maintenance - Press briquette compaction
Model MMH 103


  • The hydraulic press of briquette compaction is an hydraulic machine making it possible to carry out the hydraulic maintenance of system to jacks
  • Support for adjustments activities, diagnosis, replacement of failing components and improvement of the system.
  • The machine is able to be used only or joined with mixer MMH 102 and a system of conditioning of briquettes out of paperboards and palletization of the paperboards (consult us).
  • The machine is delivered supplements, instrumented, with technical handbook and practical work.
  • Material of industrial type.
  • Teaching concerned: Maintenance of industrial systems and complementary mentions in hydraulics
