Castor wheels
The castor wheels have a width of 50 mm. On the S208L and S210, the available
castor wheel materials are Vulkollan and Polyurethane. On all other truck models,
Vulkollan is used as the castor wheel material. Depending on the application, the
wheel suspension differs. Discounting the S212S that does not have castor wheels,
two different suspension systems are used:
Suspended castor wheel mounting.
Fixed castor wheel mounting.
Feature
When the truck turns or passes a bump, pressure increases on one castor wheel as
a result of compression of the spring. Thanks to the torsion tube, the other spring
will compress by an identical amount.
Benet
The truck remains stable and will never start to rock and travel like a 'walking
duck', a classic phenomenon when spring forces do not interact.
Feature
When one castor wheel passes a hole or
ends up outside a ramp, the torsion tube
prevents the spring from extending more
than the spring suspending the wheel res-
ting on the surface.
Benet
In an extreme case, when one castor wheel for example loses its footing outside a
ramp edge, there is no risk the wheel suspension assembly will be knocked apart
when the wheel regains its footing. This is because the wheel that has lost its foo-
ting and become unloaded remains at the same height as the wheel resting on the
ramp/surface. With a conventional wheel design, this kind of situation often causes
