Model A

Areas of application

  • for short travel distances
  • can be used to transport heavy loads in mining, steel, machine and bridge construction or as heavy roller conveyors.
  • particularly stable construction thanks to continuous cover plate
  • can be screwed to the load

main features

  • robust overall construction (frame construction)
  • low height with high load capacity, dimensions identical to AS + AM series
  • fixed connection, as the load plate or cover plate can be screwed in place
  • most stable load acceptance and distribution
  • Model A-H (with hardened centre plate) is used when the roller skate is not moved under heavy load for a long period of time. This prevents the hardened steel rollers from pressing into the standard non-hardened centre plate and ensures consistently low rolling resistance.
  • Model A-H-50CrV4 (roll material 50CrV4) is recommended if the risk of short-term overload beyond the specified load capacity of the roller skates cannot be ruled out or is likely.

Instructions for use

  • Models I-IIIv have 4 mounting holes: the middle ones are omitted.
  • Maximum displacement speed: ≤ 5 m/min.
  • For uncontrollable load distribution problems (e.g. wind pressure), choose models with a hardened centre plate and higher-quality roller material 50CrV4.
  • The rolling resistance for models I-IIIv is 7–5% of the total load, depending on the track, and 5–3% for the larger models.
  • Also available with guide rollers
  • Modifications to the drilling pattern in the top plate on request
  • Corrosion protection (galvanising or stainless steel) on request
