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

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)

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

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
