| GUIDANCE |
|
| Do's |
| 1. |
Know the
weight being lifted, and also allow for
the weight of your gear. |
| |
|
| 2. |
Always
select lifting gear of adequate strength
and see that it is properly marked; no
chain or rope should be used for any load
exceeding the safe working load. |
| |
|
| 3. |
Ensure
that end links, rings or shackles are
riding freely on any hook on which they
hang. |
| |
|
| 4. |
Care
should be taken when using Collar Slings
that the lifting hook does not bear on
the small end of the egg link. |
| |
|
| 5. |
Use wood
or other packing to protect the sling
from any sharp edges on the load. |
| |
|
| 6. |
Avoid
shocks due to (a) the load slipping, or
(b) snatch in starting. The stress on all
gear is much greater if the load is
applied suddenly. |
|
| |
| Don'ts |
| 7. |
Never use
an excessively pitted, corroded or worn
chain. (Condemn and cut it up). |
| |
|
| 8. |
Never use
a chain in which links are locked,
stretched or do not move freely. |
| |
|
| 9. |
Never
join chains by bolting or wiring links
together. |
| |
|
| 10. |
Never
shorten a chain by tying knots - use an
shortening clutch or keep an adequate
supply of slings of suitable lengths. |
| |
|
| 11. |
Do not
drag a chain from under a load, or drop
it from a height. |
| |
|
| 12. |
Do not
hammer a link to straighten or force it
into position. |
| |
|
| 13. |
Do not
use the load chain of a block as a sling
by hooking round the load. |
| |
|
| 14. |
Do not
carry idle slings on the crane hook at
the same time as loaded sling. |
|
|
| Multiple Leg
Slings |
| 15. |
The
Lifting Equipment Engineers Association
recommends a standard normal practice of
marking and certifying multi-leg slings
with the safe working load with each leg
at 0 - 45 degrees from vertical. Avoid
too wide an angle between legs - above 45
degrees from vertical the Safe Working
Load decreases rapidly. |
| |
|
| 16. |
If you
cannot be sure of loading all legs
equally, use a sling strong enough to
carry all the load safely on those legs
which may have to support it. |
|
|
| Endless Slings |
| 17. |
Endless
chain slings must be used with care to
avoid possible overloading or damage to
links by bending too sharply. The Lifting
Equipment Engineers Association of Great
Britain recommends a standard normal
practice of marking and certifying
endless slings with the safe working load
equal to 1.5 times the load on the single
chain. This allows some margin of safety
of varying conditions of use. |
|
|
| Wire Rope Slings |
| 18. |
Wire
ropes should never be bent at any point |
| |
|
| 19. |
Wire
ropes should never be in contact with hot
metal |
| |
|
| 20. |
Wire
ropes should not be allowed to become
rusty |
|
|
| Fibre Rope and
Webbing Slings |
| 21. |
Rope and
Webbing Slings should be frequently
examined for external chafe and cutting,
as well as internal wear between strands
and deterioration of the fibres. Slings
should be placed on a flat surface in a
well lit area and examined over the whole
length and particularly inside the eyes. |
| |
|
| 22. |
Rope and
Webbing Slings should not be thrown on
the ground and left there. Such action
can result in the ingress of dirt which
will have a detrimental effect on the
life of the sling. All damp slings made
from natural fibres should be properly
and slowly dried in a well ventilated
store to avoid the risk of damage from
rot. |
|
|
| Shackles |
| 23. |
The Safe
Working Load of a shackle depends upon
several factors, e.g. body size, pin
size, body opening and jaw opening. Be
sure that any shackle used has the
correct pin and is suitable for the load
to be carried. |
