Requirements for verification testing, if needed, are include

12、d.Studies have shown that the tow rope, used for retrieving a large disabled or mired earth-moving machine is seldom larger than 40 mm diameter wire rope. This is typically the largest size that can be handled by the person connecting the tow rope to the machine.Therefore, this International Standar

13、d is applicable to machine-mounted retrieval devices of capacities not exceeding 106 N. This value corresponds to the minimum breaking force of a 40 mm diameter Group 3 wire rope with steel core as listed in ISO 2408.NOTE 1 In accordance with ISO 6750, information on the location and instructions fo

14、r proper use of retrieval devices is provided in the operator manual.2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standa

15、rds are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.ISO 60

17、 DefinitionsFor the purposes of this International Standard, the following definitions apply.3.1 machine-mounted retrieval deviceconnector attached to a machine that provides a means to attach a tow rope, a chain, or a tow bar to a disabled or mired machine3.2 capacity (of a retrieval device)value,

18、expressed in newtons, of the force applied to a machine-mounted retrieval device that results in a stress level equal to the yield strength of the material that is used to manufacture the retrieval device3.3 machine mass for calculation1) For tractor-scrapers and dumpers: Combined mass of the machin

19、es operating mass, as defined in ISO 6016, and the rated paymass as specified by the manufacturer.NOTE 2 This mass is the “loaded mass”. (See ISO 7132 and ISO 7133.)2) For all other machines: Operating mass of the machine, as defined in ISO 6016.3.4 maximum pull angleangle of 20 which is the include

20、d angle of a cone with an axis that is a horizontal line passing through the tow rope connecting point on the machine-mounted retrieval device and parallel to the longitudinal axis of the machine, but limited by interference with parts of the machine4 Requirements4.1 The capacity, in newtons, of the

21、 machine-mounted retrieval device shall be equal to 1,5 times the machine mass for calculation (see 3.3), multiplied by the acceleration due to gravity (g) except for tractor-scrapers and bottom dumpers. For these machines the capacity, in newtons, shall be equal to the machine mass for calculation

22、multiplied by the acceleration due to gravity (g).NOTE 3 The capacity of the retrieval device for any machine need not exceed 106N. (See Scope.)4.2 The machine-mounted retrieval device shall withstand the capacity defined in 4.1 at the maximum pull angle.4.3 The machine-mounted retrieval device shal

23、l be made of materials that display visible signs of deformation (yield) before failure (fracture) so that it is apparent that it has been overloaded and must be repaired or replaced.4.4 The machine-mounted retrieval device shall be designed to accept a wire rope sling or clevis of a size capable of

24、 withstanding the force corresponding to the capacity defined in 4.1.4.5 If a pull-pin type retrieval device is used, provisions shall be made to retain the pin in place during use and to prevent the pin from being lost when it is not in use.BS 6911-10:19962 BSI 20064.6 The machine-mounted retrieval

25、 device may be mounted at the front and/or rear of the machine. It shall be in a location that is easily accessible for attaching a tow rope, a chain, or a tow bar.For machines with a machine operating mass larger than 105kg, a second retrieval device should be provided on the same end of the machin

26、e. Each device shall conform with the requirements of this International Standard.4.7 The machine operating manual shall provide instructions regarding the method of retrieving or towing the machine if the manufacturer recommends that devices such as wire ropes, chains or links be wound around struc

27、turel members as a means for retrieval.5 Verification5.1 The performance requirements of the retrieval device and its supporting structure on the machine shall be verified by testing or by calculation.5.2 If verified by testing, one pull at the maximum pull angle in the horizontal plane and one pull

28、 at the maximum pull angle in the vertical plane shall be made. The force applied shall correspond to the capacity defined in 4.1. Tolerances for test loads and pull angle shall be as given in ISO 9248.BS 6911-10:1996 BSI 2006 3Annex A (informative) Bibliography1 ISO 2408:1985, Steel wire ropes for
