Model AS-H

Range of application

  • For longer distances and/or permanent loads on suitable tracks, crane rails or steel beams
  • Movement of heavy loads for longer distances or for progressive shifting of scaffolding and shuttering in bridge construction. Also used for hangar doors (hardened shelters), as crawler tracks, in nuclear power stations, in institutes for nuclear research, on oil rigs, in the ship building industry and for tunnel constructions.
  • particulary stable construction through continious cover plate
  • particulary wear-resistant due to chain guide (no lateral starting of the hain, mthus no wear of the bolt heads)
  • can be bolted to the load

Key Features

  • Extra robust construction
  • Low level construction with higher carrying capacity, exchangeable with models …AM and …A due to same outer dimensions
  • More stability achieved, if load is firmly bolted to roller skates
  • More stable operation and distribution of load
  • Reduced wear by center plate chain guide (no contact between chain and sidewalls, no wear to rivet heads)

Hints on use

  • Models I-IIIv have 4 bolt holes as standard 
  • If problems of load distribution occur e.g. by wind forces, it is necessary to select moedel AS-H_50CrV4
  • Maximum speed: 5m/min
  • The rolling resistance depends on the track. For smaller models I-IIIv 7-5%, for larger models 5-3% of the total load
  • 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 
  • Several models for off-shore puposes approved by LRS, ABS, DnV
