Safe Operating Guidelines
Before operating a
MSI
crane scale, the scale operator should
carefully read and study the appropriate Operation Manual
supplied by
MSI
and note any special instructions.
Operating suggestions
1. Do not make lifts beyond rated load capacity of the
crane scale, sling chains, rope slings, etc.
2. Do not operate the crane scale if ropes, slings, cables,
chains, etc. show any sign of defects or excessive wear.
3. Before moving the load, make certain that load slings,
load chains or other lifting devices are fully seated in the
saddle of the crane scale hook with hook latch closed.
4. At no time should a load be left suspended from the
crane scale unless the operator is at the master
switch or push buttons with the power on; and under
this condition keep the load as close to the floor as
possible to minimize the possibility of an injury, should
the load drop. When the crane scale is holding a load,
the crane operator should remain at the master switch or
push buttons.
5. When a hitcher is used, it should be the joint responsibil-
ity of the crane operator and the hitcher to see that
hitches are secure and that all loose material has been
removed from the load before starting a lift.
6. Do not lift loads with ropes, slings, cables, chains, etc.
hanging loose.
7. All ropes, slings, cables, chains, etc. should be removed
from the crane scale when not in use. (A dangling cable
can inadvertently snag other objects when the crane is
moving.)
8. Operators should not maneuver a loaded crane scale
over personnel.
Handling hoist motion
After the crane scale hook has been positioned over the load,
lower it until the load can be attached to the scale hook. As
the scale hook approaches this level, reduce the speed so
that the lowering can be stopped smoothly and quickly.
