Signals only work if both parties learned the same set. That is the entire
point of standardising them.
The rules around the signals
- One signaller at a time, agreed out loud before the lift starts
- Stop applies from anyone. Not only the signaller
- The operator acts only on what he actually saw or heard — if the signal is
unclear, the crane stops - If contact is lost, the default is to stop. See
exclusion zone and communication - If the signaller changes mid-job, it is said out loud and confirmed
The signals
The signals that apply are the standard set from Kranteknisk Forening. We do not
show them here: the chart is KTF’s, and we will not reproduce it without
permission. The link below goes to the source.
The signal chart is published by Kranteknisk Forening.
Rather than show our own drawings of signals we do not own, we point you at the source. KTF publishes the chart used on Norwegian sites, and the guidance sits in the KTF standard. Have the real poster where the work happens.
The Norwegian chart
Kranteknisk Forening publishes the hand signal chart used in Norwegian crane
work, and the guidance sits in the KTF standard. If signals are to hang where the
work happens, it is that poster that should hang there — not a web page. See
links.
When signals are not enough
If the operator cannot see the load, the signaller is the operator’s eyes, and
the demands on communication and discipline rise. See the articles
Blind lifts and Radio discipline.
The capacity is on the sling, not on this page. This section explains the geometry and the method. It states no working load limits and no reduction factors for hitch types — those differ between slings and belong to the equipment's own marking, its certificate, and the assessment made at sakkyndig kontroll. Calculate the force with the calculator; read what the sling will take off the sling. If the two do not agree, the lift does not happen.
