HHC / DRS - Supporting your local and European ambitions.


HHC/DRS has an agreement with the Dutch TCVT foundation regarding the implementation of the following guidelines for supervision on the certification of vertical transport:

  • WDA&T_WSCS guideline for the inspection of mobile cranes, truck-mounted cranes and earth-moving machines outfitted as mobile cranes.
  • W5 guideline for the inspection of rail infrastructure machines, with or without the addition of local tracks*.
  • W6 guideline for the inspection of piling equipment, its use, mounting, as well as periodical inspections.

* In collaboration with the TCVT foundation and local railway companies GVB, HTM, RET and RTU, HHC/DRS has developed a certification guideline that can be used to assess maintenance equipment for these various local railway companies in terms of infrastructure compatibility and safe usage thereof. If you have any questions regarding the implementation of this guideline, please feel free to contact our railway account manager, Mr A. Schipper: a.schipper@hhcdrs.nl.
