Definition of oblique pulling
Oblique pulling is the deviation of the load chain and
the chain hoist from the vertical position, for a force
acting in a straight-line between the point of force
application of the load on the load hook and the
point of suspension on the supporting structure.
Under special safety provisions relevant to the
particular situation, JDN Air Hoists may be used
for oblique pulling (see
Intended use , page 15).
In this case, a chain box must not be used as the
chain may fall out or become knotted.
Oblique pulling is not permitted for hoists installed
in trolleys or in running gear. Please contact us,
if required.
