MODEL A

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

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

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

Location of the fixing holes can be arranged to suit customers requirements.
Optional in galvanised or stainless steel construction
