Using Tag Ropes
Use tag ropes to control the position of the
barrier being lifted. They should not be too long,
8 metres is adequate for a load 3 sections high.
They should be attached to the lifting eyes
towards the ends of the barrier sections.
A light pull for a limited period is all that is
needed to control the barrier; any more will give
the barrier momentum which has then to be
stopped.
Do not wrap the rope around your hand or
fingers and avoid treading on or over the rope.
Keep at least 3 metres from the barrier as slight
adjustments with the crane can cause a
pendulum effect along the barrier.
NEVER GET BETWEEN THE LENGTH OF
BARRIER AND A SOLID OBJECT. A SWINGING
BARRIER CARRIES ENERGY AND CAN CRUSH.
Using Chains
All fabric slings and metal chains must be
checked before use to ensure:
•
That they are undamaged.
•
The load imposed is within
their capacity.
The recommended chains to
use are two leg sets each leg 2
metres long, each with a
shortening clutch to allow tilting
the barrier if required. They are
rated at 2 tons per pair provided
that the angle between the legs
does not exceed 90° or 2 tons
per leg if one leg is used with the
chain vertical.
It is recommended that before using the chains:
•
Check the number on the chain against the
test certificate and check that the test
certificate is current.
•
Check the chain for damage - look at the
links for distortion and nicks. Look at the
hooks - not bent open, not twisted, latches
working.
•
Check the chain lengths for the lift being
carried out and shorten one leg if necessary
to adjust the slope of the barrier. Shortening
one chain will raise the end with the short
chain. Check the chain is properly seated in
the shortening clutch. If hook type
shortening clutches are used, the chain goes
across the hook into the slot formed by the
hook. The point of the hook does not go into
the chain link!
