Further necessary actions for the overlifting of both, delivery sections on crane lugs
as well as monoblocs
The AHU sections or monoblocs must be lifted with appropriate equipment e.g.
-
belt with hook.
-
The recommended minimum load capacity per load carrying equipment is 50%
of the total weight of the delivery section or monobloc.
-
The length of the load carrying equipment must permit a favorable course, see
Figure 22.
-
The course of the load carrying equipment must be chosen so that overhanging
attachments, roofs and the like will not be stressed or damaged.
Load carrying equipment shall not run over sharp edges and is not allowed to
-
be knotted.
The load carrying equipment must be secured against slipping off.
-
After a slow lifting from the floor for a few centimeters the correct course of the
-
load carrying equipment as well as the safe support of all fastening elements
should be checked.
Before further lifting it must be checked, that no abnormal deformation at the
suspension points/load carrying equipment can be detected by visual inspec-
tion.
-
Avoid jerky lifting.
Make sure that nobody is under the raised load.
-
-
Never lift AHU sections or monoblocs on heat exchanger connections or other
attachments.
-
The load carrying equipment is not permitted to exceed an angle of maximum
15 ° to the vertical and must be spread apart to avoid damage to the casing, re-
fer to Figure 22.
