(13) Arrange slings securely
If the slings are not fitted securely, the load can fall off or slip
out of the slings and fall down. Arrange slings securely with
attention to the following points.
・
The sling wire ropes or chains used to suspend the load from
the hook should be the right size and undamaged. Damaged
slings could break and drop the load. Arrange the slings so that
they do not interfere or tangle with each other.
・
The hook is fitted with a retainer to prevent the slings from
slipping out. Check that it works correctly. If not, there is the
risk that the slings could slip from the hook causing the load to
fall. So have it repaired or replaced before you proceed with
hoisting.
・
Place protectors of some soft material to protect the sling wire
ropes where they come into contact with corners of the
suspended load or anywhere they are prone to damage.
(14) Crane up objects one by one
Attempting to crane up the plural number of objects at a time is
very dangerous because it makes difficult for the operator to
watch all objects evenly. Such an attempt can also cause uneven
loads to be applied to the boom, possibly resulting in damaged
boom. Avoid craning up two or more pieces of load at a time
even if the total mass does not exceed the rated capacity.
(15) Use the crane only as intended
Attempts to draw out objects buried in the ground or to draw up
objects whose mass is not known can apply unexpected large
load on the various parts of the crane, possibly causing the crane
to be damaged or the machine to fall down. Examine and
discuss the mass of load and the working process with the
worksite manager before beginning with the work.
