CAPACITY:
The amount of tension a sling will hold given the type
of hitch being used, the sling angle, and sling
size.
CENTER
OF GRAVITY: Point through which the resultant weight
force passes, whatever the position of the body or system
of bodies. The location of the center of the weight
of the load.
DESIGN
FACTOR: The ratio of the nominal strength of a sling
to the total working load limit of the sling
D/d
RATIO: The sheave or bend diameter divided by the nominal
wire rope diameter.
ENGINEERED
LIFT: A lift using a sling specifically designed for
a specific load and usually limited to a specific number
of loadings.
LOAD
CONTROL: The ability of the sling to control the movement
of the load being lifted.
|
PROOF
LOAD: The specific load applied in performance of the
proof test. Generally, the proof load is twice the working
load, but may be any value specified by the user.
PROOF
TEST: A nondestructive tension test made by the sling
manufacturer to verify construction and workmanship
of the individual sling.
RATED
CAPACITY: The load which a new wire rope or wire rope
sling may handle under given operating conditions and
at an assumed design factor.
SHOCK
LOAD: A resulting load from the rapid change of direction
such as jerking or jarring a motionless load.
