DIN EN ISO 4375:2015-03 EN ISO 4375:2014 (E) 3 1 ScopeThis International Standard defines the requirements for equipment, anchorage, supports and accessories for cableway systems for use in stream gauging. Systems which are operated e
23、ither entirely from the river bank or from a suspended personnel carriage (also called a “cable car”) are discussed. This International Standard is only applicable to the cableway systems to be used for hydrometric measurements. Should the cableway installation be required to be certified as lifting
24、 equipment, other standards or regulations may apply. This International Standard does not concern methods for making a discharge measurement which are described in ISO 748.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispe
25、nsable for its application. For dated references, only the edition cited applies.

26、onsFor the purposes of this document, the terms and definitions given in ISO 772, ISO 80000-4 and the following apply.3.1cablewire rope of simple or complex structure or wire cord, fixed or moving in a cableway system4 General description of a cableway system4.1 Elements of a cableway systemA cablew
27、ay system can be designed to be operated from the river bank (see Figures 1 and 2) or be designed to be operated from a suspended personnel carriage (see Figure 3). The general arrangement of the following elements are common to both systems:a) towers or cableway supports;b) track or main cable;c) a
28、nchorage;d) backstays;e) suspension cable.The main differences are: the carriage of a bankside system requires a tow cable; a bankside system requires a more complicated winch arrangement;DIN EN ISO 4375:2015-03 EN ISO 4375:2014 (E) 4 the personnel carriage has to provide a safe platform for the ope
29、rator; more stringent design requirements may apply to a system which employs a personnel carriage.Key1 backstay 7 distance measurement2 traversing cable return pulley 8 depth measurement3 track or main cable 9 cable drum4 traveller and/or instrument carriage10 footing5 current meter 11 ground level

32、ports, one on each bank, support the main cable span across the stream. They may also provide mountings for the winch and the pulleys (sheaves) carrying the tow and suspension cables.4.3 Main track or main cableThe track or main cable is designed to carry the whole suspended load. The track may be a
33、ttached directly to stayed cableway supports or be supported on saddles on the cableway supports and led directly to an anchorage.4.4 AnchorageAnchorages are required to carry the loads induced in the cableway and tower system. Depending upon the design of the system, they may be anchorage points fo
34、r track and backstays or guy-lines, tower foundations subject to compression or tower foundations subject to compression and moment.4.5 Tow cable for a bankside systemThe tow cable is required to move and position the instrument carriage. Generally the tow cable is arranged as an endless loop from t
35、he instrument carriage over guiding sheaves on the winch tower, round a driving pulley or drum, across to an idler pulley (sheave) on the tower on the opposite bank and back to the carriage (see Figure 1). An alternate arrangement uses a spooled tow cable with a single fixing point on the carriage.
36、This arrangement depends upon the equal and opposite force provided by the suspension cable (see Figure 2).4.6 Suspension cableThe suspension cable provides the means of raising and lowering sensing or sampling equipment in the stream. The free end of the cable is fitted with connectors to attach eq
37、uipment and sounding weights. The suspension cable is likely to contain an insulated conducting core to provide a signal path from suspended instruments.DIN EN ISO 4375:2015-03 EN ISO 4375:2014 (E) 6 4.7 Instrument carriage for a bankside systemThe instrument carriage is provided with one or more tr
38、ack wheels running on the main cable (track), a pulley to support the suspension cable and a point of attachment for the tow (traveller) cable.4.8 Personnel carriageThe carriage from which gauging observations are made, travels along the main cable. It is suspended from track wheels running on the m
39、ain cable. The carriage may be moved along the main cable manually or by a power unit. The carriage can be designed to be operated from either the standing or sitting position or both. A cableway employing a personnel carriage shall comply with the safety requirements for passenger cableways where s
40、uch standards exist specially for horizontal fixed cableways, in all aspects not covered by this International Standard.4.9 Winch arrangements for a bankside systemA double drum winch is one that provides both traversing and sounding functions within one piece of equipment. One drum controls the sus
41、pension cable, the other controls the movement of the carriage. The latter may be a spooling drum or take the form of a friction drive pulley driving an “endless” loop. Both drums may be driven simultaneously in traversing mode or, in sounding mode, the traversing drum may be locked to allow operati
42、on of the suspension cable drum only. This operation may also be carried out using two single drum winches. Measuring counters may be fitted to record horizontal and vertical cable movement.4.10 Winch arrangements for a personnel carriageA winch (sounding reel) is attached to the carriage (cable car
43、) to raise and lower the sounding weight. The winch is required to operate properly under the load of the sounding weight but both the winch and its mountings should be capable of accommodating the breaking load of the suspension cable with a factor of safety (FoS) of two. The winch may be hand oper
44、ated or power driven.4.11 Lightning protectionIn areas where electrical storms are considered a risk to cableway operators, provision shall be made to reduce the likelihood of injury from a lightning strike on the cableway system. In countries where lightning is infrequent and lightning protection n
45、ot considered necessary, work instructions should allow for abandonment of operations in the event of an electrical storm.5 Functional requirements of cableway components5.1 Safety factors5.1.1 GeneralFactors of safety shall be applied to ensure that the equipment is able to cope with normal working
46、 without failure and to protect the operator in case of abnormal but foreseeable incidents.The most likely risk of failure of properly maintained cableway systems lies with the possibility of the suspended equipment becoming caught up on a large floating object. Trees being carried down in a flood a
47、re the most likely source of this danger. The excess loading is applied to the system through the suspension cable. In a bankside system, the tension in this cable is equal to, and balanced by, the tension in the “return” side of the tow cable. In both bankside systems and systems with personnel carriages, the load in the suspension cable is also applied to the main cable (track) through the carriage.For both arrangements, the
