Where the crane is cabin-controlled, the brake shall be capable of being locked on.

Appropriate Parts of the AS series may provide detailed requirements for out of service brakes. Wheels and rails shall comply with Clauses 7. A safety device shall monitor the magnet currents in the power cabling to the magnets and the magnets themselves and shall render the magnet system inoperative should the current drop below the safe operating current level.

Rating plates shall be located so that details recorded on them can be conveniently read. 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.

For service brakes, failure of any one brake shall not reduce the overall brake static torque below 1.

Where monitors ss duplicated, they shall be checked automatically one against the other, and shall be interlocked with the system of controls in a positive and fail-safe manner. Rail joints should not coincide with a joint in the rail-supporting structure or a joint on the opposite runway. Complete wiring diagrams of the system or systems in the control panelswhich should include schematics, panel layouts, connection diagrams, cable schedules, equipment layouts or any other information that may be necessary to allow safe and efficient maintenance and fault rectification to be carried out.

Neither following nor ignoring the recommendation results in non-compliance with the Standard. For hoists, equipped with two independent wire ropes, failure of one rope shall not reduce the rope system coefficient of utilisation Zp below 3.


Where several transformers are used, it is recommended that the windings of those transformers be connected in such a manner that the secondary voltages are in phase.

The edge between grooves shall be rounded. Allowable stress design Part 2: The other hoist drive shall be considered to be stationary. Where the rope is accommodated in less than two complete layers, the drum shall be flanged at the end, remote from where the rope is anchored. In both cases you should know how to switch cookies back on! Where dynamic analysis cannot be carried out due to unavailable data, then the loadings specified in Clause 7. To maintain their currency, all Standards are periodically reviewed, and new editions are published.


Between editions, amendments may be issued. The warning device shall be able to be controlled by the crane operator and shall also activate automatically when the crane is in motion. Each load group is divided into load categories as shown in Table 7. For more information phone 65 46 46 or visit Standards Web Shop at www.

Live loads on walkways during maintenance shall be determined in accordance with AS unless higher loads can be generated, for example, placement of equipment on walkways during maintenance.

As an example for load combination 7 of Table 9, the total load P tot in an assumed mechanism would be derived from: It was approved on behalf 14181 the Council of Standards Australia on 15 February Where appropriate the cable shall comply with Clause 8. Suitable provision should be made to control the flexing and twisting of hoses and tubing during normal operation.

Where all switches called for in this Clause and in Clause 8. For that reason, stresses are determined as reference quantities for the stress analysis.

The pneumatic system should be thoroughly cleaned prior to testing.

Where applicable, the advantages of a hollow piston rod and the use of cushion-ended cylinders or deceleration valves to prevent shock loadings should be considered. A detailed analysis is provided in Appendix E. When an automatic crane is operating wholly over an elevated platform, tank or structure that is not less than mm above the surrounds then a separate enclosure need not be constructed but the access ways to the top of the elevated structure shall comply with Items c and d ii above.

For cranes with booms, wind loads shall be considered in fatigue calculations. For classification of other motions where insufficient data exists the following guidance may be used: Design of the rings and brushgear shall eliminate the possibility of bridging the rings in the event of brush breakage and similar, which would render the control system unsafe.

Any requirements that apply to only one type of crane should only appear in the specific part for that crane and not in Part 1. However the following additional requirements shall be incorporated: For design purposes, Km and the value for running hours shall be that specified in Tables 7. A activation email has been sent to you. The lower-bound value of the coefficient of friction between the driven wheels and the rail shall be determined on the basis of tests or, in the absence of tests, the following values shall be used: Gas accumulators should be charged with nitrogen or other inert gas.


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. Particular attention shall be given to those components and subassemblies that are exposed to corrosion, fatigue and wear. Refer to specific parts of AS for material Standards applicable to a particular crane type.

The number of loading cycles is often significantly higher than the number of in-service cycles in Table 2. In addition, the protection associated with the high-voltage supply to the crane shall include an earth-leakage protective device which shall ensure that during an earth fault condition the rise in potential on the crane structure or its parts with respect to earth and the time to clear the fault potential shall not exceed the recommended values for touch voltage and time contained in AS for prospective touch voltage a.

The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected. Where pedal controls are provided for single foot operation, a footrest shall be provided to support the free foot.

The clips shall be arranged in pairs located on opposite sides of each side of the crane rail and spaced at centres not greater than mm, or as recommended by the competent person or manufacturer. Stop functions shall override related start functions.

In some circumstances, the effects of the kinetic energy of the rotating long travel components, e. An example is anti-condensation heating of motors. The hook bolts shall be placed on alternate sides of the rail at 75 mm to mm centres, spaced at centres no greater than mm.
