Definitions

  • the shelters required for the maintenance and inspection of the facilities are temporarily made.
  • elevator systems of this kind up to a delivery height of 3 m, as a rule, no safety-related acceptance by a named Job required, provided the manufacturer has appropriate manufacturer certificates.
  • the lift height is the travel distance that the platform can cover at maximum.
  • Simplified elevator systems of this type can be used in lift shafts, which i. d. R. bricked or concreted are mounted. In most applications, however, these systems are delivered with a hoistway scaffold. This can be mounted as a load-bearing or self-supporting shaft scaffolding indoors or outdoors.
  • the load-bearing shaft framework construction consists of posts or longitudinal struts and bars in the form of steel profiles, usually hollow steel profiles.
  • shaft scaffolds are often lined with glass, façade panels or other material.
  • a drive system mainly spindle drives and hydraulic drive systems are offered on the elevator market.
  • the drive spindle or the hydraulic ram and the guide system are mounted on a side wall or the rear wall.
  • the elevator platforms are guided cantilevered on one side as a "backpack system”.
  • the drive motor or the hydraulic unit is located either on the drive side behind a veneer (spindle drives) or outside the elevator shaft (hydraulic units).
  • a side or rear wall is installed by the required technology (drive spindle, hydraulic ram, guide rails, etc.).
  • This wall side can, if architecturally desired, be clad. In shear and crushing hazards by the driving motion such a wall cladding is mandatory. With glass elevators, the resulting reduced transparency is distracting.
  • the clad wall side can also not be used for a possible car access and requires additional space.
  • "backpack systems" in comparison to centrally suspended systems have poorer handling characteristics, which can be achieved, for example, by stick-slip effect. and resulting car vibrations during travel. Among other things, this leads to higher noise emissions, which in homes lead to impaired living comfort.
