15、vedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which

16、a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matt

17、ers of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circul

18、ated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsib

19、le for identifying any or all such patent rights. ISO 10245-3 was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 7, Tower cranes. This second edition cancels and replaces the first edition (ISO 10245-3:1999), which has been technically revised. ISO 10245 consists of the following

20、 parts, under the general title Cranes Limiting and indicating devices: Part 1: General Part 2: Mobile cranes Part 3: Tower cranes Part 4: Jib cranes Part 5: Overhead travelling and portal bridge cranes SANS 615-3:2009This s tandard may only be used and printed by approved subscription and freemaili

It is applicable to tower crane

22、s as defined in ISO 4306-3. It is not applicable to end stops such as buffers used to stop trolleying, travelling or derricking movements, nor to erection, dismantling operations or the changing of a cranes configuration. NOTE General requirements for the devices are given in ISO 10245-1. 2 Normativ

27、s indicator device that indicates the horizontal distance between the centreline of a crane and the centreline of the suspended load 3.3 working space limiter device to prevent, on a single crane, the risk of moving loads and/or crane parts into a protected space 3.4 protected space space in which m

28、ovement of the load and/or any crane part is absolutely not allowed NOTE Generally, when out of service, the jib and the counter-jib are permitted to move into the protected space. 4 Rated capacity limiters and indicators General requirements 4.1 Rated capacity limiters and indicators shall be provi

29、ded on all cranes having a rated capacity of 1 000 kg or above, or an overturning moment of 40 000 Nm or above due to the load. 4.2 Features shall be incorporated to minimize the risk of accidental change of any manual setting device (e.g. by locking, double action). 4.3 In addition to the requireme

30、nt of ISO 10245-1:2008, 4.2.4, rated capacity limiters and indicators may require adjustment after a change in the crane configuration out of normal operation, e.g. reassembly or adding of crane parts like jib extensions. 4.4 ISO 10245-1:2008, 4.2.6, is not applicable to tower cranes. 4.5 The design

31、 and installation of rated capacity indicators and rated capacity limiters shall take into account the need to test the indicator or limiter. Where it is necessary to disconnect parts of the devices during testing, facilities shall be provided to check and/or reset the devices after the test. 4.6 If

32、 interruption of the power occurs, the setting of limiters and indicators shall be retained. 5 Rated capacity limiters 5.1 Tower cranes shall be equipped with rated capacity limiters as described in ISO 10245-1:2008, 4.3. 5.2 The rated capacity limiter shall activate at not less than 102 % and not m

33、ore than 110 % of the rated capacity. 5.3 Provision for overriding the rated capacity limiter shall not be provided. Use of the alternative setting of the standard rated capacity limiter foreseen by the manufacturer is not considered as overriding if the crane is kept within its designed and stated

34、capacity as given in the instruction handbook. 6 Rated capacity indicators 6.1 Tower cranes shall be fitted with a rated capacity indicator in accordance with ISO 10245-1:2008, 4.4. 6.2 As the crane approaches its rated capacity, the rated capacity indicator shall give clear and continuous visual an

35、d/or audible warning to the operator. The warnings shall commence at not less than 90 % and not more that 95 % of the rated capacity.

36、ved 36.3 On tower cranes provided with remote controls, this rated capacity indicator may be installed on the crane. It shall give a visual warning signal. 6.4 The rated capacity indicator shall give a clear and continuous warning when the rated capacity is exceeded. The warning shall be visual at t

37、he operators control station and audible to the crane operator and to those in the vicinity of the crane. The warnings shall commence at not less than 102 % and not more than 110 % of the rated capacity. 6.5 Systems shall enable periodic functional checks to be carried out to verify that indicators

38、are operating correctly. 6.6 No provision shall be made for the crane operator to cancel a warning from the control station, except when both audible and visual warnings are used for the same situation, in which case the audible warning has been active for 5 s. If such a cancellation facility is use

39、d, the warning shall automatically operate if the crane subsequently returns to a condition requiring an audible warning. NOTE Provision may be made to cancel the audible warning during calibration and testing of the crane. 6.7 There shall be a clear difference between the warning for approach and t

40、he warning for overload, e.g. a visual warning may be one colour for the approach and another colour for overload. 6.8 Warnings shall be in accordance with IEC 60204-32:, 10.2.2, 10.3 and 10.8, and IEC 61310-1:2007. 7 Motion and performance limiting devices 7.1 Motion limiters 7.1.1 Motion limiters

41、shall be provided in accordance with of ISO 10245-1:2008, 4.5.1, and Table 1, below. Table 1 Motion limiters Type Required to be provided Hoisting limiter YES Lowering limiter YES Slack rope limiter NO Slewing limiter NO if power supply via a slipping assembly Travelling limiter YES Derricking limit

42、er YES Telescoping limiter NO during erection YES, if under working conditions Control station position limiter YES, if the control station is moved during service Working space limiter aNot mandatory, at the request of the user Anti-collision device bNot mandatory, at the request of the user Trolle

43、ying limiter YES aA working space limiter and a crane being interdependent of one another, the power supply shall be such that when the crane is “on”, the working space limiter is automatically “on”. bSee Annex A.

45、et action has been carried out. This reset action shall not be readily available to the crane operator at the control position. The indication and reset action are not required when the second limiter is a fixed stop designed to absorb the energy of the motion. 7.1.3 Each tower crane shall be capabl

46、e of being equipped with an anti-collision device. If parts of a crane and/or loads are in a certain space, this device shall stop motions from following cranes to avoid collision in this space and allow the reverse movement. The crane manufacturer shall determine the connection points necessary for

47、 the action of the device on the movement or function of the crane. The choice of these connection points and the given orders shall be such that the device actions are compatible with the normal use of the crane mechanisms (decelerating before stopping high-inertia motions, mechanical brakes applic

48、ation). All connection points necessary for the installation of the device on the crane motion shall be assembled in a specific collector or on a dedicated cable. This specific collector or dedicated cable shall be installed on all cranes except on self-erecting cranes. NOTE Annex A provides some gu

49、idance for the anti-collision device. 7.1.4 The tower crane shall be capable of being equipped with a working space limiter. This device shall be designed to stop motions in order to avoid entering a forbidden area and allow the reverse movement. 7.1.5 When it is necessary to override motion limiters in normal operation (e.g. change of the fall number, storage of the trolley) provision may be at the control station. The overriding devices shall be hold-to-run types and the crane components and the
