4.3 Dismantling of the lifting bag system
after use
Dismantling of the lifting bag system is carried out after ensuring
the lifted load and complete deflation of the lifting bag system,
including dismantling of all accessory parts in the reverse order.
4.4 Limit for the period of use
Ultra Flat Bags S.Tec are subject to natural aging the same as any
other rubber products. The aging of the material is initially indi-
cated by the loss of flexibility which especially becomes aparent
with the appearance of so-called aging cracks. If these cracks pro-
pagate in the cover material so that the ARAMIDE reinforcement
is no longer protected by the cover layer then this can lead to a
crack networks forming on the surface and thus cause bursting
of the bag.
The experiences gained in the last decade have clearly shown
that the general failure rate with rubber products considerably
increases from a period exceeding 15 years. Therefore Ultra Flat
Bags S.Tec should be replaced after 15 years, 18 years is the maxi-
mum. The danger for rescue services when using aged Ultra Flat
Bags S.Tec should never be underestimated for welfare reasons. It
should be stressed that although there is currently no regulation
about the maximum time limit, the responsibility rests fairly and
squarely with the user and the inspector commissioned by him.
4.5 Care, maintenance and storage
The lifting bag equipment is to be cleaned after every operation.
Cleaning is normally made with warm water and a soap solution.
Cleaning must never be carried out with
chemicals and high-pressure hot water
devices.
Drying is to be made at normal room temperature.
A bag is to be immediately discarded if, during inspection, any
sign of damage is established (refer to Page 6). Repair is not pos-
sible. If needed, components such as manometers, safety valves
and piston valves can be exchanged. Hose couplings and nipples
can also be exchanged. After necessary repair, the equipment is
to be checked according to the repetitive tests. This special test is
also to be documented.
DIN 7716 is to be observed for long-term storage.
The VETTER Guarantee is 36 months for Ultra Flat Bags S.Tec.
