Model A

Applications 

  • For short displacement routes
  • transports heavy loads in mining,steel,machine,and bridge construction or as heavy roller conveyors
  • particularly stable construction through contiuous cover plate
  • can be bolted to the load

Key Features

  • robust overall construction (frame construction)
  • low overall height with high load capacity, identical in dimensions with AS+AM series 
  • firm connection, because the load or cover plate can be screwed
  • most stable load absorption and distribution
  • Model A-H (with hardened center plate) is used when the rollerskate is not moved under high load for a long time. As a result, a pressing of the hardened steel rolls is prevented in the standard non hardened center plate and ensures a uniformly low rolling resistance
  • Model A-H-50CrV4 (roll material 50CrV4) is recommended if the risk of short term overload beyond the specified bearing capacity of the rollerskates can not be excluded or is probable

Operating Tips

  • Models I-IIIv have 4 fixing holes: the middle ones are omitted
  • maximum displacement speed:  5m/min
  • for uncontrollable load distribution problems (eg wind pressure) choose models with hardened center plates and higher quality 50CrV4 roll material 
  • Rolling resistance on models I-IIIv is 7-5% depending on the track conditions, 5-3% of the total load on the larger models 
  • also available with http://boerkey-gmbh.de/de/produktuebersicht/fuehrungsrollen/
  • Location of the fixing holes can be arranged to suit customers requirements.
  • Optional in galvanised or stainless steel construction
