heavyMaster HM and HM-F in-line sliding door

The problem-solver for special requirements

The heavyMaster sliding door drive is the problem-solver for your special requirements.
Sliding panels with large dimensions or heavy weights of up to 200 kg are driven reliably and silently.
Even in very high-traffic entrance areas, the heavyMaster ensures optimal running
characteristics with the least wear, thanks to the stable carriage and large rollers with
rubber-coated running face. Sliding Panels framed with thermally broken Profile systems or steel profiles are ideally suited for assembly with heavyMaster.
The drives are certified to DIN 18650/EN 16005 and type-tested by TÜV and comply with the current directives and standards. The HM-F drive system is tested and suitable for use in escape and rescue routes (AutSchR).

Convincing in detail:

  • Type HM-F: Redundant drive with 2 motors for use in escape and rescue routes
  • Stable carriage with large rollers
  • Running smoothness thanks to rollers with an exchangeable rubber-coated running face
  • Clear and simple operation
