6 Precautions for Use

Most accidents involving a clamp are caused by incorrect handling during slinging work or an incorrect
working method. Workers must be proficient in the correct method of using clamps, and strive to carry out
safe work.

Precautions and explanatory diagrams

Using at least two clamps at pre-marked
positions, install the clamps so that they
surround the center of gravity of the
suspension load.

During this work, strive to ensure that the
sling angle between the clamps is no greater
than the following angles.
 Suspension angle   60
 Attachment width angle   30
Vertical suspension

Confirm that the screw, the screw cap and the
cam operate smoothly.

Check the teeth to see if they are worn,
chipped, bent or clogged.

Reason
If the load were to be
suspended using a single
clamp, it would be liable to
set up vibration even the
clamp were attached to the
center of gravity of the load.
If the screw, screw cap or
cam does not operate
smoothly, the specified
tightening force may fail to be
attained, causing the
suspension load to drop. This
may also occur if a tooth is
chipped.
