KS, KSA and NK Important Instructions
• Never Use on fragile loads. (For fragile items us
the
NX
series clamp)
• Never use for personnel lifting Strictly forbidden to
walk or be under the load.
• Never exceed the working load limit.
• Using this clamp marks the load. (For non-
marking use the
NX
series clamp)
• The plate or piece to be lifted must always be
driven home into the throat of the clamp.
• Surface hardness of pieces to be lifted: maxi. 300
Brinell (
KS
)/ 330 Brinell (
NK
) and minimum
29,000 PSI tensile strength (20 daN/mm²).
• Some stainless steels are particularly abrasive.
Inspect for wear of teeth of the cam in this case.
• When not in use, ensure clamps are always
unlocked (cam closed).
• Never lift more than one plate at a time.
• Apply the downgradation if necessary (see
sketch).
• The minimum weight of lifting load should be
equal to 5% of the clamp’s WLL (e.g. if clamps
WLL is 1 ton, then minimum weight is 100 lbs.).
This value is given for a clamp in new working
order and respecting Tractel
®
Inc. conditions of
use and recommendations. Consult Tractel
®
in
case of loads with weight less than the minimum
recommended value.
• Lifting clamps are not suitable for creating
permanent joints. Working temperature: -20° to
+100°C.(-10º to +212ºF)
After an intensive period of use, the chain or ring
may show signs of elongation, wear, or other
damage which could cause the chain or ring to
break. It is therefore recommended that the lifting
chain is inspected regularly Corroded or cracked
links, distorted or twisted links, worn or
stretched links require that the unit be taken out
of service until replaced. A written inspection log
should be maintained.
