Handling guidelines for the SIGMA materials handling hose system
In addition to the general handling guidelines for rubber hoses, it is important to observe the following points
when using SIGMA materials handling hose system due to their large physical dimensions and measurements:
In principle, SIGMA hoses are to be handled on pallets regardless of delivery method
(coiled, up to DN 152, straight, above that) so as to prevent any damage to the hose.
When delivered straight, it is recommended that the hoses be handled by two fork lifts.
A hoisting eye must be used if individual hoses or hose bundles must be moved by forklifts without the
use of pallets.
When transporting the hoses they must be sufficiently secured every time so as to prevent any damage
during transport.
SIGMA hoses must not be dragged across the ground or over sharp-edged objects despite their size.
At no time, neither during transport nor storage, may objects be placed on the SIGMA hose; otherwise
imbedded wire helixes will be in danger of becoming permanently warped. Only SIGMA hoses may
be stored on top of each other.
It is very important to note that pressure sensitivity increases with the increasing nominal width of the
hose.
Due to the high mass of the SIGMA materials handling hose system, it is recommended that hoisting
equipment and the like be used when handling the hoses for ergonomic reasons.
