What kinds of casters are available and how are they used?
1) A "Pipe caster" (which is inserted into the pillar on the
four corners) is used when the load they must bear is
less than 100 kg (220 lb.) ; see Creform caster JC-50,
75, CJR-65, 75, YGR-50 and 100.
2) A "Bottom base frame caster" (which is installed to the
bottom base frame) is used when the load is more than
100 kg; please consult "customer service" about these
Creform casters; CJ, CK, YJ and YK.
3) The choice of caster should be made based on load,
weight of the structure itself, frequency of use, floor
surface, noise considerations, price and so on when
you make your cart.
