AS 5236.1:2021 pdf free.Cranes — Limiting and indicating devices Part 1: General (ISO 10245-1:2008, MOD).
4.3.2 Operating requirements
4.3.2.1 When the load on the crane exceeds the rated capacity, the rating capacity limiter shall override the controls of the crane to prevent any condition that will increase the overload.
For particular crane types, reference should be made to ISO 10245-2, Iso 10245-3, ISO 10245-4 or ISO 10245-5 for details of motions that will increase the overload.
4.3.2.2 The rated capacity limiter shall not prevent the crane operator from returning the controls to the “stop” position nor from initiating actions that will move the crane to a reduced-loading or unloaded condition.
4.3.2.3 The rated capacity limiter, once triggered, shall continuously override the controls concerned until the overload has been removed and the relevant control lever has been returned to the neutral position.
4.4 Rated capacity indicators
4.4.1 Operating requirements
4.4.1.1 The rated capacity indicator shall give visual or audible warnings, or both, for all motions of the crane that induce a load in excess of the rated capacity as shown in the information supplied by the manufacturer for the particular crane.
4.4.1.2 The rated capacity indicator shall
a) for those cranes where the rated capacity varies with the position of the load, warn the crane operator when the rated capacity is approached,
b) warn the crane operator and persons in the danger zone when the rated capacity limiter is activated,
c) for those cranes where a limiter override is provided, warn the crane operator and persons in the danger zone whenever the rated limiter has been overridden.
4.4.1.3 When the rated capacity is approached, the rated capacity indicator shall give a warning at a value which gives the crane operator time to react to the warning and prevent the crane from being overloaded.
For particular crane types, reference should be made to ISO 10245-2, ISO 10245-3, ISO 10245-4 or ISO 10245-5 for details of motions that will increase the overload.AS 5236.1 pdf download.
