(a) The employer shall ensure at a construction site of a building or other construction work that,—
(i) every crane, if so erected that the safe working load may be varied by raising or lowering of the jib or otherwise, is attached with an automatic indicator of safe working loads, which gives a warning to the operator wherever the load exceeds the safe working load; and
(ii) cut-out is provided, which automatically arrests the movements of the lifting parts of every crane, if the load exceeds the working load, wherever possible;
(b) the provisions of sub-clause (i) of clause (a) apply, except where it is not possible to install an automatic safe load indicator, in which case, the provisions of a table, showing the safe working loads at the corresponding inclinations or radial of the jib on the crane, shall be considered sufficient.
