MDS
Suitable for engine manufacturing

The SCHAAF Mounting Documentation System (MDS) is a pressure generator that documents the tightening procedure for bolted joints. This ensures 100% verifiability of the joint quality. The material homogeneities are monitored (according to Hooke‘s Law) during generation of the pre-tightening force.
This involves monitoring of the pressure - elongation curve. All additional quality parameters can be specified individually and the system meets the tightening specifications and shuts down automatically when an error appears.



MDS in use on crankshaft bearing tensioners and as elongation controller - also optionally with pressure control.

Design variants

MDS can be provided with the following options:

  • Colour or B+W printer
  • Radio-operated remote controller with display
  • LAN/W-LAN/USB interface
  • Remote access for remote maintenance
  • TMS interface (Tool Management System)
  • TSI interface (Tool Service Indicator)
  • Radio-operated sensors
  • Sensors integrated in the bolt tensioners or supplied separately
  • Central specification of bolting data via SAP interface, database, USB interface or copy and paste
  • 1-3K design type for separate control of multiple independent pressure circuits
  • Rotation angle and torque control for bolt tensioners with automated motorised re-tightening function
  • Optional colour coding of the used equipment

Areas of Application

SCHAAF MDS is ideally suited for:

  • Generating a bolt pre-tensioning force for which 100% operational sequencing, safety and data logging are required.
  • Engine-building: Main bearing, connecting rod bearing, cylinder head
  • Power plants: e.g. Turbines, compressors
  • Ring gear bolt connections: e.g. wind power plants
  • Tower fittings: e.g. crane construction
  • General mechanical engineering
