A crane, other than a crane fitted with remote controls in accordance with 6 of Appendix 11, must not be used in loading or unloading unless, where the crane is provided with a cabin, the cabin:
(a) provides the operator with a clear and unrestricted view of the load and area of operation or of a hatchman, from the operating position of the crane;

(c) is adequately heated in cold weather by means that do not emit noxious or objectionable fumes;
(d) is adequately ventilated by mechanical means;
(e) is equipped with a suitable seat and, where necessary, footrests;
(f) if fitted with an access door, allows the door to be operated from both inside and outside the cabin, has an opening at least 550 mm wide and 1850 mm high (including any sill, the height of which must not exceed 450 mm), and, where the door is of a type which may become so obstructed as to prevent rescue in case of emergency, allows access to the cabin through a second opening;
(g) is constructed of fire‑proof materials;
(h) in the case of an electrically operated crane or a crane in which electrical equipment connected with the crane's operation is installed, contains:
(i) a carbon dioxide type fire extinguisher complying with Australian Standard AS 1841.6; or
(ii) a dry powder type fire extinguisher complying with Australian Standard AS 1841.5 that relates to an extinguisher in which a mixture of dry powder and expellant is stored under pressure; or
(iii) a suitable fire extinguisher of an equivalent type and standard;
(i) has been so designed that noise and vibration remain within acceptable limits;
(j) shields the operating position and seat from the effects of radiated heat from the driving mechanism;
(k) where the crane is capable of hoisting a load to the level of the operating position, is fitted with windows of laminated glass, toughened safety glass or a material offering equivalent protection; and
Note: Only windows that are at risk from being struck by a swinging load need to be fitted with safety glazing materials. .
(l) is provided with illumination operable from the control position.
Note: Safety requirements of the Navigation Act apply whether a ship is at sea or in port. It should be ensured that in providing the required fire extinguisher, another area of the ship is not rendered unsafe in terms of the Safety Convention or other survey requirements.
2 Access to operating position
2.1.1 Access to the operating position of a crane must be provided by means of:
(a) a spiral stairway ladder complying with 4 of Appendix 17; or
(b) an inclined ladder or ladders complying with 3 of Appendix 17; or
(c) a vertical ladder or ladders complying with 2 of Appendix 17; or
(d) any combination of (a), (b) or (c).
2.1.2 The top of any access opening in a crane pedestal must be at least 1850 mm above the deck. If a sill is fitted, it must not exceed 450 mm in height. The clear width of the opening must be at least 550 mm.
2.2 Where access is installed inside the structure of the crane or crane pedestal, a reliable means of emergency escape must be provided outside the structure unless:
(a) there is no machinery sited in the access way;
(b) the access route is provided with lighting;
(c) any electrical wiring in the access way, other than for light fittings, is contained in sealed metal conduit; and
(d) any electrical equipment in the access way is contained in properly secured metal boxes.
Note 1: 'Properly secured' means that to open the box it is necessary to use a screwdriver, spanner or special tool.
Note 2: An appropriate escape provision may be considered to include:
(a) fixed ladders in conjunction with platforms or landings;
(b) fixed rungs with a landing ledge, together with handrail, leading to a vertical ladder;
(c) a wire rope ladder, permanently secured at its upper end.
Note 3: Instructions for use of the means of escape should be provided.
2.3.1 A vertical external access ladder, other than an emergency escape ladder, that is:
(a) of a height exceeding 3 metres; or
(b) of any length if the crane can be located so that a person using the ladder could fall into a cargo space, overboard or onto a deck lower than that on which the ladder originates,
must be fitted with a ladder cage which would substantially prevent such a fall, unless the ship's structure provides equivalent protection.
2.3.2 For the purposes of 2.3.1, a ladder cage should consist of cage hoops and longitudinal strips, of adequate strength, fitted substantially in accordance with the following specifications:
(a) cage hoops uniformly spaced at intervals not exceeding 900 mm, so that:
(i) where the top of the ladder terminates at the edge of a platform or deck, the topmost cage hoop is attached to the upper guard-rail; or
(ii) where the top of the ladder terminates at an access opening in a platform or deck, the topmost cage hoop is fitted just below the level of the platform, except that where the cage longitudinals are secured to the platform or deck, the topmost hoop may be sited not more than 900 mm below the platform or deck; and
(iii) the lowest cage hoop is located not less than 2 metres and not more than 2.2 metres above the deck or platform adjacent to the base of the ladder;
(b) cage longitudinals, secured to the cage hoops, suitably spaced to prevent a person falling away from the ladder;
(c) a rear half of the cage approximately semi-circular in shape;
(d) a minimum clear internal width of 550 mm and a maximum clearance between the ladder rungs and the back of the cage of 750 mm; and
(e) does not hinder use of the ladder rungs or handholds.
2.4 A platform on a crane must be adequate for the purpose and, except as provided by 2.6, must comply with 6 of Appendix 17.
2.5 If a ladder gives access to a crane through an opening in a platform on the crane:
(a) the ladder stringers must extend at least one metre above the floor level of the platform or handgrips must be provided to that height;
(b) the end of each stringer must be provided with adequate lateral support; and
(c) the top step or rung of the ladder must not exceed one tread pitch below the floor of the platform.
2.6 A platform providing access around or along a crane must;
(a) have a minimum breadth of 550 mm; and
(b) provide safe access to and from the crane at any operating angle of luff or slew of the crane.
2.7 A ladder giving access to the operator's position of a crane must be located in relation to any access opening in the floor of a platform or walkway, so that the ladder:
(a) in either fore and aft direction or stowed position of the jib, must not be positioned over the opening; and
(b) must not pass over the hole while the crane is slewing.
2.8.1 An internal access opening in the floor of a crane cabin must be provided with:
(a) in the case of a crane where the access ladder passes through a machinery space and is not separated from that space by a solid steel, or other fire and smoke resistant, barriera solid hinged cover; and
(b) in any other casean expanded metal, hinged cover.
2.8.2 Provision 2.8.1 applies to cranes installed on ships built after 11 August 1997, and to all cranes when an existing cover is replaced.
2.9 Provisions 2.1, 2.3, 2.4, 2.5, 2.7 and 2.8 do not apply to derrick cranes. Provisions 2.2 and 2.6 apply to derrick cranes so far as their application may be relevant and practical.
2.10 A crane installed on a ship before 17 November 1986 must comply with 2.2 to 2.7 inclusive so far as is technically practicable taking into account the ship's structural arrangements.
3 Weather protection
A winch must be provided with adequate weather protection for the driver at the operating position.
