Transporting, stacking and storing
▪
Observe all country-specific regulations applying to
the handling of scaffolding. For system scaffolding
the Doka slinging means stated in this booklet must
be used – this is a mandatory requirement.
If the type of sling is not specified in this document,
the customer must use slinging means that are suit-
able for the application envisaged and that comply
with the regulations.
▪
When lifting, always make sure that the unit to be
lifted and its individual parts can absorb the forces
that occur.
▪
Remove loose parts or secure them so that they can-
not slip out of position and drop.
▪
When lifting scaffolding or scaffolding accessories
with a crane, no persons must be carried along, e.g.
on working platforms or in multi-trip packaging.
▪
All components must be stored safely, following all
the special Doka instructions given in the relevant
sections of this document!
Maintenance
▪
Only original Doka components may be used as
spare parts. Repairs may only be carried out by the
manufacturer or authorised facilities.

actual weights can differ, depending on material toler-
