101. The disembarkation zone must be located so that it can be quickly abandoned and the towing devices can be restored to their original state.

102. In the landing zone of the BKD with drum-type towing devices, the drums must pass at a height of at least 2.3 m from the surface of the snow cover. In this case, after disembarking the passenger, the haul rope should not overlap with the road structures and towing devices on the side of the descent.

The distance from the traction rope of the BKD with rod towing devices to the surface of the snow cover must not be less than the length of the assembled towing device.
(Clause as amended, entered into force on June 10, 2016 by order of Rostechnadzor dated April 28, 2016 N 170. - See previous edition)

103. The slope of the disembarkation zone should not exceed 6 ° towards the exit to the track:

BKD with drum devices directly behind the support;

For BKD with rod-type towing devices, so that passengers release the towing devices immediately after the clamp passes the last support;

The paragraph is excluded from June 10, 2016 - Rostechnadzor order of April 28, 2016 N 170. - See previous edition.

104. At the upper station, the distance (L) between the beginning of the skiers uncoupling point and the point where the rope enters the pulley or balancer should ensure that the towing device assumes its initial position, namely:

With a drum type device L 12 V;

With a rod-type device L 4 V,

Where V - maximum speed roads, m / s.

It is allowed to reduce this distance if the safe passage of the towing device in the station area is ensured.

On a BKD with towing devices of both drum and rod type, passengers are allowed to exit at the pulley, if this is provided for by the design of the station.
(The paragraph is additionally included from June 10, 2016 by order of Rostekhnadzor of April 28, 2016 N 170)

105. Behind the disembarkation zone, control devices are installed that automatically stop the road in the following cases:

The passenger did not have time to let go of the towing device;

The towing device did not return to its original state.

106. On the BBKD track, control devices are located behind the disembarkation zone so as to exclude the possibility of a passenger approaching the pulleys.

107. Information signs should be installed in the landing zones:

Advance notification of the landing site;

Release the towing device;

Do not linger at the drop-off point.

Ropes

108. Steel ropes used on the construction site must be of a cargo-people purpose, non-twisting. The conformity of the rope must be confirmed by a certificate issued by the manufacturer of the rope.

109. The tensile strength of ropes must correspond to the parameters determined by the formula:

Breaking strength of the rope as a whole, taken according to the certificate or test certificate;

S- the highest rope tension;

The minimum safety factor adopted in accordance with the criteria given in paragraphs 118 -122 of these FNP.

110. If the manufacturer's certificate (test certificate) indicates the total breaking strength of all wires, the breaking strength of the rope as a whole is determined by multiplying the total breaking strength of all wires by the section loss factor.

111. The cross-section loss coefficient is:

For round ropes - 0.83;

For ropes of a closed structure - 0.9.

112. The choice of the rope should be made in accordance with the criteria given in table N 1.

The information on rope classification given below is far from new, and we can hardly add anything new. You can easily find similar materials on other resources, so why do we host it? Looking at the classification presented below, you will understand that there are a large number of types of rope and sometimes it is quite difficult for even a specialist to figure out what a rope 12-GL-VK-L-O-N-1770 GOST 2688-80 is.

Working with the same ropes, it is quite easy to decipher everything, but what if the client wants to buy a non-standard rope? This is where “Where to look? Where to get? What does this letter mean in the name? " We have previously published material about the ropes, but did not describe the classification in detail, so we hope that this article will be useful to you.

Classification, technical requirements, test methods, rules for acceptance, transportation, and storage of steel ropes are set out in GOST 3241-91 “Steel Ropes. Technical conditions ".

Classification of steel ropes

• single lay or spiral consist of wires twisted in a spiral in one or more concentric layers. Single lay ropes twisted only from round wire are called ordinary spiral ropes. Spiral ropes with shaped wires in the outer layer are called closed ropes. Single lay ropes intended for subsequent lay are called strands.
• double lay consist of strands twisted into one or more concentric layers. Double lay ropes can be single-layered or multi-layered. Single-layer six-strand double-lay ropes are widely used. Double lay ropes intended for subsequent lay are called strands.
• triple lay consist of strands twisted in a spiral into one concentric layer.

2. By the shape of the cross-section of the strands:

• round
• shaped(triangular-strand, flat-strand), have a much larger surface of contact with the pulley than round-strand.

3. By the type of strands and ropes of single lay:

• TC- with a point contact of the wires between the layers,
• OK- with a linear touch of the wires between the layers,
• LK-O- with a linear touch of the wires between the layers with the same diameter of the wires along the layers of the strand,
• LK-R- with a linear touch of the wires between the layers at different wire diameters in the outer layer of the strand,
• LK-Z- with a linear touch of the wires between the strand layers and the filling wires,
• LK-RO- with a linear touch of the wires between the layers and having layers in strands with wires of different diameters and layers with wires of the same diameter,
• TLK- with combined point-linear contact of wires in strands.

Strands with point contact of wires are made in several technological steps, depending on the number of layers of wires. In this case, it is necessary to apply different wire lay steps for each layer of the strand and wind the next layer in the opposite direction to the previous one. As a result, the wires between the layers intersect. Such an arrangement of the wires increases their wear during shears during operation, creates significant contact stresses that contribute to the development of fatigue cracks in the wires, and reduces the filling factor of the rope section with metal.
Strands with linear touch of wires are made in one technological step; at the same time, the constancy of the lay step is maintained, and the same direction of the lay of the wires for all layers of the strand, which, with the correct selection of the wire diameters in the layers, gives a linear tangency of the wires between the layers. As a result, the wear of the wires is significantly reduced and the operability of ropes with a linear touch of the wires in the strands increases dramatically in comparison with the operability of ropes of the TK type.
Strands of point-linear tangency are used when it is necessary to replace the linear tangency of the central wire in the strands with a seven-wire strand, when a layer of wires of the same diameter with a point-contact is laid on a single-layer seven-wire strand of the LK type. Strands may have enhanced anti-spin properties.

4. By core material:

• OS- with an organic core - as a core in the center of the rope, and sometimes in the center of the strands, cores made of natural, synthetic and artificial materials- from hemp, manila, sisal, cotton yarn, polyethylene, polypropylene, nylon, lavsan, viscose, asbestos.
• MC- with a metal core - as a core, in most structures, a double lay rope of six seven wire strands is used, located around the central seven wire strand, in ropes according to GOST 3066-80, 3067-88,3068-88 a strand is used as MC the same design as in the braid. It is advisable to use them when it is necessary to increase the structural strength of the rope, to reduce the structural elongation of the rope during tension, as well as at a high temperature of the medium in which the rope operates.

5. By lay method:

• Non-spinning ropes - H- strands and wires retain their predetermined position after removing the ties from the end of the rope or are easily stacked manually with slight unwinding, which is achieved by preliminary deformation of the wires and strands when stranding wires into a strand and strands into a rope.
• Untwisted ropes- wires and strands are not pre-deformed or insufficiently deformed before they are twisted into strands and into a rope. Therefore, the strands in the rope and the wires in the strands do not retain their position after the tying is removed from the end of the rope.

6. By the degree of balance:

• Straightened rope - R- does not lose its straightness (within the permissible deviation) in a free suspended state or on a horizontal plane, because after stranding the strands and spar, respectively, the stresses from the deformation of the wires and strands were removed by straightening.
• Unlined rope- does not have such a property, the free end of an unaligned rope tends to form a ring, due to the deformation stresses of the wires and strands obtained in the process of manufacturing the rope.

7. In the direction of the rope lay:

• Right lay- not indicated
• Left lay- L

The direction of the rope lay is determined by: the direction of the lay of the wires of the outer layer - for single lay ropes; the direction of stranding of the strands of the outer layer - for double lay ropes; the direction of stranding into the rope - for triple lay ropes

8. By the combination of directions of the rope and its elements:

• Cross lay- the direction of strands and strands lay opposite to the direction of the rope lay.
• One-sided lay - O- the direction of stranding in the rope and wire in the strands are the same.
• Combined lay- K with the simultaneous use of strands of the right and left directions of the lay in the rope.

9.According to the degree of coolness

• Spinning- with the same direction of twisting of all strands along the rope layers (six- and eight-strand ropes with an organic and metal core)
• Low-spinning- (MK) with the opposite direction of stranding rope elements in layers (multilayer, multi-strand ropes and single lay ropes). In non-rotating ropes, due to the selection of the directions of the lay of individual layers of wires (in spiral ropes) or strands (in multilayer double lay ropes), rotation of the rope around its axis is eliminated when the load is freely suspended.

10. By the mechanical properties of the wire

• VK brand- High Quality
• Grade B- high quality
• Grade 1- normal quality

11. By the type of coating of the surface of the wires in the rope:

• Uncoated wires
• Galvanized wire depending on the surface density of zinc:
• group C- for medium aggressive working conditions
• group F- for harsh aggressive working conditions
• coolant group- especially harsh aggressive working conditions
• NS- rope or strands are covered with polymeric materials

12. According to the purpose of the rope

• Gruzoludskie - GL- for lifting and transporting people and goods
• Freight - G- for lifting and transporting and loads

13. By manufacturing accuracy

• Normal Accuracy- not indicated
• Increased accuracy - T- toughened maximum deviations in the diameter of the rope

14. By strength characteristics
Marking groups of ultimate tensile strength N / mm2 (kgf / mm2) - 1370 (140), 1470 (150), 1570 (160), 1670 (170), 1770 (180), 1860 (190), 1960 (200), 2060 (210), 2160 (220)

Each rope design has advantages and disadvantages that must be properly considered when choosing ropes for specific operating conditions. When choosing, it is necessary to maintain the necessary ratios between the diameters of the winding organs and the diameters of the ropes and their outer wires, as well as the necessary margin of safety, ensuring trouble-free operation.

Single lay round wire ropes - ordinary spiral (GOST 3062-80; 3063-80; 3064-80) have increased rigidity, therefore, it is recommended to use them where tensile loads on the rope prevail (lightning protection cables high voltage lines power lines, fences, stretch marks, etc.)

Double lay ropes with linear tangency of wires in strands with ease of manufacture, they have a relatively high efficiency and have a sufficient number of various designs.The latter allows you to choose ropes for operation at high end loads, with significant abrasive wear, in various aggressive environments, with the minimum permissible ratio of the diameter of the winding element and the diameter of the rope.

LK-R type ropes (GOST 2688-80, 14954-80) should be used when, during operation, the ropes are exposed to aggressive media, intense alternating bending and work on outdoors... The high structural strength of these ropes allows them to be used in many highly stressful crane operating conditions.

LK-O type ropes (GOST 3077-80, 3081-80; 3066-80; 3069-80; 3083-80) work stably in conditions of severe abrasion due to the presence of wires of increased diameter in the upper layer. These ropes are widespread, but their normal operation requires a slightly increased diameter of blocks and drums.

LK-Z type ropes (GOST 7665-80, 7667-80) used when flexibility is required, provided that the rope is not exposed to an aggressive environment. It is not recommended to use these ropes in an aggressive environment because of the thin filler wires in the strands that are easily corroded.

Ropes of the LK-RO type (GOST 7668-80, 7669-80, 16853-80) are characterized by a relatively large number of wires in the strands and therefore have increased flexibility. The presence of relatively thick wires in the outer layer of these ropes allows them to be successfully used in conditions of abrasive wear and aggressive media. Due to this combination of properties, the rope of the LK-RO type construction is universal.

Double lay ropes with point-linear contact of wires in strands of TLK-O type (GOST 3079-80) should be used when the use of ropes by linear contact of the wires in the strands is impossible due to violation of the setting minimum permissible ratios between the diameters of the winding elements and the diameters of the rope wires or when it is impossible to ensure the recommended safety margin.

Double lay ropes with point contact of wires in strands of TK type (GOST 3067-88; 3068-88; 3070-88; 3071-88) not recommended for demanding and intensive installations. These ropes can only be used for non-stressed operating conditions, where alternating bends and pulsating loads are insignificant or absent (slings, bracing ropes, temporary timber-alloy fasteners, supporting and brake ropes, etc.)

Multi-strand double lay ropes (GOST 3088-80; 7681-80) depending on the accepted directions of stranding strands along separate layers made ordinary and non-rotating. The latter provide reliable and stable operation on mechanisms with free suspension of the load, and a large supporting surface and lower specific pressures on the outer wires allow to achieve a relatively high performance of the rope. The disadvantages of multi-strand ropes are the complexity of manufacturing (especially preliminary deformation), the tendency to delamination, the difficulty of monitoring the state of the inner layers of the strands.

Triple lay ropes (GOST 3089-80) They are used when the main operational requirements are maximum flexibility and elasticity of the rope, and its strength and supporting surface are not decisive. Organic cores in strands are useful when the rope is intended for towing and mooring, where increased elastic properties of the rope are required. Due to the use of wires of small diameters in comparison with wires of double-lay ropes, triple-lay ropes for normal operation require pulleys of significantly smaller diameters.

Three-sided strand ropes (GOST 3085-80) They are characterized by increased structural stability, a very high fill factor and a large bearing surface. The use of these ropes is especially advisable for high end loads and severe abrasive wear. It is recommended to use these ropes both in installations with friction pulleys and in multilayer winding on drums.The disadvantages of three-sided strand ropes are sharp bends of wires on the edges of the strands, increased rigidity of the rope, and laboriousness of manufacturing strands.

Flat ropes (GOST 3091-80; 3092-80) find application as balancing in mine hoisting installations. The advantages of these ropes include their non-twist. However, the manual operations involved in sewing the ropes and the relatively rapid destruction of the thong during operation limit the scope of use of these ropes in industry.
