STG 4000-2K

Electro-hydraulic two-circuit high-pressure automatic control system for fully automatic pressing of hubs onto shafts and separating

Especially for fully automatic pressing and loosening of joints on shafts, Schaaf, GmbH & Co. KG developed the Electro-hydraulic two-circuit high-pressure control system STG 4000-2K. In areas where a 100 % functionality, safety and repeat accuracy is necessary the system performs at its best. It stops the tightening processes at target/ actual deviations and indicates clearly an error message if the press input was not met. This eliminates hub and shaft damages. While pushing on and extending a hub the pressure transformer and distance measurement sensor constantly monitors and records the process (such as pressure time, pressure way, pressure pressure diagram). The system is designed for the industrial use and is sturdy, compact, maintenance free and durable.

Advantages

  • 100% fulfilment of the press fitting requirement
  • 100% process control and immediate securing of the stop of the tightening process in plan/actual deviations
  • Error reports in plain text if the process requirements are not complied with
  • No hub damage, no shaft damage Permanent monitoring of the pushing and the extension of the hub via a number of pressure transformers and distance measuring sensors.
  • Pressure/time, pressure/distance, pressure/pressure diagrams can be output as a QA protocol
  • Free occupation of parameters for tightening and loosening
  • Robust, compact, maintenance-friendly and long-life construction designed for industrial use
  • Password-protected parameter input
  • Parameterised time control and pressure monitoring for switching pressure free after tightening
