MDS

Mounting Documentation System for control and monitoring of the axial, hydraulic bolt-tightening process.

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.

Advantages

  • 100% documented quality of bolt connections
  • Increased work safety thanks to frequent pressure and elongation characteristic monitoring (according to Hooke‘s Law)
  • Automatic shutdown in case of process errors
  • Guarantee of the correct bolting load
  • Ability to prove that the generation of pre-tensioning force was correct in the event of damage thanks to documented logging of the tension positions and pressures and clamping procedure
  • Self-monitoring of the MDS by means of integral self-test and redundant pressure transmitter monitoring
  • Simple, clear and comfortable user interface that leads through process
  • Automated control of multiple pressure circuits in accordance with different pre-tensioning force generation programs
  • Over 60,000 original data sets of tightening parameters can be stored
  • Password-protected parameter input
  • Simple copy and paste of new data sets for new bolting conditions
  • Mobile or fixed units possible
  • Operator guidance in selectable language
  • Long service lifetime and user-friendly maintenance intervals
  • Integral Tool Service Indicator (TSI)
  • Optional Tool Management System (TMS)
  • Ideal for individual or series assembly– rapid pre-tensioning force generation
  • Data output as diagram or table
  • Data output on customer quality assurance sheets
  • Precise pressure generation with a tolerance
  • of ± 10 bar at 4000 bar. More precise pressure range regulation in various pressure ranges according to customer requirements.
  • Almost unlimited capability for archiving of tightening procedures for individual or complete bolt-tightening systems
  • Assembly errors are eliminated due to integrated process guidance
  • High load-cycle values and long lifetime
  • Tensioning programs and reports can be transferred via USB or LAN-Access

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.

Suitable for turbine manufacturing

The SCHAAF Mounting Documentation System (MDS) is controlled by a digital database that is specific to each turbine installation. All process data are accessed from the digital database and the entire tightening procedure is documented – even in the case of stepwise increase of the pre-tightening force. Operation is carried out by the separate remote control unit and can be performed from great distances due to its large display. Pressurisation to the specified values can be effected very rapidly because the SCHAAF high pressure equipment has a very high rated flow capacity.
