Twin-Path® Slings
Mechanical
/ Rigging Considerations
- Determine the weight of the load. The weight
of the load shall be within the rated capacity
of the sling.
- Select a sling having suitable characteristics
for the type of load, hitch and environment.
- Slings shall not be loaded in excess of
the rated capacity. Consideration shall be
given to angle of lift which may affect the
lifting capacity. Diameters of pins and edges
also may affect the capacity of the lifting
sling.
- Slings used in a choker shall not be forced
to tighten around the load by pounding with
hammers or other objects. Choker hitches
are the least effective way to use a sling
based on capacity. Two chokers should be
used to balance the load. One choker in the
center of the load may create an unbalanced
situation which could lead to an accident.
- Slings used in a basket hitch must have
the load balanced to prevent slippage and
accidents.
- Slings used with fittings shall be compatible
with the fittings used. The lifting capacity
shall be rated at the lower of the fitting
or sling. Fitting openings shall be of the
proper shape and size to assure that the
sling will seat properly.
- Slings shall be protected from cutting
and edges. All protrusions and abrasive surfaces
will be kept from contact with the sling.
Where unavoidable situations develop padding
shall be placed between the sling and load.
The pin area of a shackle can cause synthetic
slings to cut and placing synthetic slings
on the pin should avoided.
- Slings shall not be dragged on the floor
or drawn across other surfaces which may
damage the sling.
- Slings shall not be twisted or tied in
knots or shorten.
- Slings shall not be pulled from under loads
resting on the sling.
- Do not drop objects on slings or run over
them with vehicles.
- Slings which are damaged shall not be used.
- Sling hitches must provide control of the
load.
- Portions of the human body shall be kept
from between the sling and the load and from
between the sling and any attachment to lifting
devices such as hooks.
- Personnel shall stand clear of suspended
loads.
- Personnel shall not ride on the sling or
suspended loads.
- Avoid snatch or shock loading.
- Twisting and kinking the legs of the sling
shall be avoided.
- Load applied to the hook should be centered
in the bowl of the hooks. Do not point load
the hook.
- During lifting with or without the load
all personnel shall be alert for possible
snagging.
- The slings should contain or support the
load from the sides above the center of gravity
so that the load will not tilt when the load
is lifted.
- Slings shall be of the proper length so
that the angle of the sling to the load does
not reduce the rated capacity of the sling
for a given angle.
- Only legibly marked or labeled slings should
be used. If the tag is not legible, or missing,
the sling should not be used.
- Keep labels or tags away from the load,
the hook and the angle of choke.
- Synthetic slings should be inspected
each time before each lift.
