PART XIV LIFTING MACHINE AND LIFTING TACKLE
Use of lifting machines or lifting tackle

14.1 No lifting machine or tackle shall be used unless :

(a) it is of good construction, sound material, adequate strength and free from any visible defect;

(b) it is so used that the safety of persons is not endangered;

(c) it is provided, where practicable, with a brake or other device which automatically prevent inadvertent downward movement of the load when the raising effort is removed;

(d) it is provided, where practicable, with a limiting device which will cut off automatically the power when the load reaches its highest safe working position; and

(e) the maximum load it is designed to carry is marked conspicuously and clearly on it; when the load varies with the conditions of use such as the varying angle of the jib, a table showing the maximum load for each condition shall be posted up in a conspicuous pace easily visible to the operator.


Factors of Safety

14.2 Any rope or chain forming part of a lifting machine shall have a factor of safety of at least 10 for fibre ropes and at least 6 for steel wire ropes and for chains, calculated its static load. When the load is shared equally by two or more ropes or chains the factor of safety may be calculated on the sum of their breaking loads.

Steel rope not to be used

14.3 A steel wire rope shall not be used on any lifting machine unless the diameter and construction of such rope is suited to the diameter of drum, pulley or sheave on which it is used.

Hand operated devices

14.4 Every windlass, crab, or winch operated by hand shall be fitted with a proper crank-handle for applying power. Where persons are being raised or lowered, two such crank-handles shall be provided and at least one person shall manipulate each handle.

Lifting hooks

14.5 Every hook used for lifting of loads shall be designed and proportioned, or shall be provided with a device so that no accidental disconnection of the load can take place.

Attachment of slings, ropes or chains to loads

14.6 No person shall attach, cause or permit the attachment of any sling, rope or chain to any load, lifting machine or lifting tackle unless :

(a) it is so attached that no accidental disconnection can take place; and

(b) the stability of the load and that of the lifting machine during lifting or transportation is ensured and maintained.

No persons to be raised, lowered, transported or supported

14.7 No person shall be raised, lowered, transported or supported by means of a lifting machine except with the written permission of the Chief Inspector and subject to such conditions as he or she may specify in his/her permission.
