Lift stability
When choosing the lifting arrangement, the sling and clamp positions must always be considered as these may also have an effect
on the stability of the lift. Please refer to
Fig. 11
,
Fig. 12a
and
Fig. 12b
to check your lift is stable
in each horizontal axis of rotation
.
When the CoG of the load is above the load’s connection points (shown in
Fig.12a
and
Fig.12b
) the load must be supported in
more than one vertical plane.
Please note that although only one plane is illustrated above, a stability check is required for
each horizontal axis of rotation
.
Orientation of lug plates
If you intend to lift with a tilt of up to 6 degrees from the horizontal
plane, please ensure the clamp lug plates are orientated as shown in
Fig. 10a. Always ensure that all clamp lug plates are being pulled to-
wards the body of the clamp. All
red safety stops
should be attached
as shown below, or as described in Fig. 3. If you require more safety
stops, or if you are in any doubt, please contact Modulift.
For
Fig.12a
and
Fig.12b
a stable lift will exist on the illustrated
plane if D>E. An unstable lift will exist on the illustrated plane
if E>D. Never carry out unstable lifts.
Stability in other plane
(not shown) depends on bottom sling rigging arrangement.
Please check each horizontal axis of rotation
.
