Suitable for the wind power industry

The SCHAAF Mounting Documentation System (MDS) is optimised for mobile and standard applications when building and servicing wind power plants. As soon as the parameters for bolting conditions are entered they become available to the operator. The text display ensures that the operator can create an assembly with 100% reliability - even in the case of problematic bolting conditions. All cases are saved in the assembly guide system so that even inexperienced workers can always achieve 100% quality during assembly.

Use of MDS for documentation
of bolt pre-tensioning force
for tower base bolting of
wind power plants.

Design variants

MDS can be provided with the following options:

  • Radio-operated remote controller with display
  • LAN/W-LAN/USB interface
  • Remote control for remote maintenance
  • TMS interface (Tool Management System)
  • TSI interface (Tool Service Indicator)
  • Radio-operated sensors
  • Integrated or separate elongation sensors
  • Mobile unit
  • Central specification of bolting data via SAP interface, database or copy and paste
  • Rotation angle and torque control for bolt tensioners with motorised re-tightening function
  • Documented pre-tightening force generation with the option of residual force detection during bolting maintenance periods


Design variants

Wind power industry Engine manufacturing Turbine manufacturing
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
