4.4.4 Load moment limiter
When permissible load moment is exceeded, the crane movements which will increase load
moment will be cut off, and only those movements that will decrease load moment are allowed.
However, the presence of load moment limiter does not relieve the crane operator of his duties
and responsibilities for safe crane operation. Before lifting a load, he must know the
approximate weight of load and decide if the crane is in a position to carry out this job with the
help of lifting capacity chart.
DANGER
The load moment limiter must be adjusted before using the crane to the current set up
condition in accordance with the lifting capacity chart. Only in this way can it be able to
fulfill its protective task.
If crane operator does not observe this safety obligation, the crane may overturn and
may be damaged beyond repair, despite the load moment limiter is working normally.
The load moment limiter can not monitor and control all possible operating conditions;
this is still primarily the responsibility of the operator.
CAUTION
The “Bypass” in this chapter means that the limited movement is allowed to move
towards dangerous direction via bypass switch after the alarm is sent out and the
system cut off the dangerous movement. This does not mean the alarm is canceled.
