AS/NZS 1418.9:1996

A safety device, which, after the low power warning device has activated and the magnet has been switched off, prevents the magnet from being switched on again until the battery is recharged to the minimum safe operating level, shall be provided. Size px x x x x Rail clamps are best suited for duty on runways with a duty classification of greater than or equal to C5.

In a applications it may be necessary to consider also occasional loads such as in service or out of ad wind, skewing az exceptional loads such as test loads and excitation of the lifting appliance foundation e. If a tilted appliance can fall back into its normal position uncontrolled, the resulting impact on the supporting structure shall be evaluated and taken into account.

The share of the load that can foreseeably be imposed on each az shall not exceed its rated capacity taking account of the rigidity of both the load and the lifting beam. Each movement of the crane shall be checked throughout its complete range in both directions under no-load conditions. Crane and hoist manufacturers, importers and agents require acceptable data that can be used in the design, manufacture, testing and acceptance inspection of cranes and hoists for both general and particular applications.

Hoses shall not be ad to support pneumatic components or other equipment. Further safety is frequently introduced by making the stop buttons latch in the open state mechanically and by requiring a reset by a start button to re-establish the contactor independently of the reset of the stop button contacts. Crane and hoist users and operators require statements of their responsibilities in the safe use of equipment. The proof of adequacy shall include proof of safety against yielding, elastic instability or fatigue.

The operation of protection of the electrical system of a crane motion shall not cause loss of any other motion where loss of such motion could create a potential hazard. Further legal aspects of crane Standards must be recognized because they may also be utilized as measures of legal responsibility.

It is beyond 1418. scope of this Standard to detail these or other approaches or to recommend the most appropriate method for particular cases. An indicator shall be provided to show if the magnet is magnetizing, de-magnetizing, magnetized or de-magnetized.

Special vision panels, where provided, shall be suitably guarded, for example, where situated at floor level. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology. Allowances given in AS For purposes of travel without a load, an effective slew-restraining device additional to the slew mechanism shall be provided, e. AS Thimbles for wire rope It has no legal authority in its own right but it may acquire legal standing in one or more of the following ways: The loads shall be combined as specified in 1148.1 4 118.1 the most adverse combinations excluding dynamic multipliers.

The ax spectrum factor K m for the mechanism is given by the following equation: The clamps shall be designed to— a prevent rotation of the clip due to longitudinal movement of the rail; and NOTE: The az of appropriate protective devices designed to accommodate special duty motors is recommended.

The nominal voltage shall not exceed V when supplied from a transformer. Where mechanisms are duplicated for safety reasons, failure shall be assumed to occur in any part of either system.

1418.1-2002(+A1)

In so far as high speed appliances are concerned, the best solution is to butt-weld the rails, in order to eliminate ss the shock loadings that 14118.1 when an appliance runs over joints. For the crane in the out of service condition, the brakes shall be designed to exert a restraining effort of at least 1.

All springs shall be designed in accordance with BS Where the cable has no intermediate support see Item d aboveexcessive sag shall be prevented by the use of a cable feeder or other automatic means.

Glare from external, natural or artificial lighting sources shall be prevented by provision of suitably placed visors on or in the cabin or by the use of tinted glass see Clause Live loads on walkways during maintenance shall be determined in accordance with AS ax higher loads can be generated, for example, placement of equipment on walkways during maintenance. The emergency stop function shall comply with the following minimum requirements: AS provides guidance on this matter.

For cranes with booms, wind loads shall be considered in fatigue calculations. Where indicating lights are provided, a test facility at the operator controls shall be provided to test the condition of the indicators. In the absence of a aa cycle analysis based on time and motion analysis, an equivalent number of load cycles to be used in the design shall be as given in Table 5.

For all gear cases, particular attention shall be paid to ensure proper lubrication of all gears and bearings.

aw This Standard has been prepared bearing in mind that it will be used by a number of different categories of users, with entirely different objectives. Provision shall be made to prevent the motor operating after the brake has been applied.

HB 13 also provides guidance for electrical equipment for hazardous areas.
