What it replaced, and why it won on finished work

A wire rope sling is stronger per millimetre of its own thickness and it survives abuse that would end a webbing sling’s life. So the swap is not a question of strength; it is a question of contact and handling. A steel rope presents a hard, narrow surface to the load and a fringe of broken wires to the hands that rig it, and on a finished article it does the damage before the lift begins. ა ვეებერთელა სლინგი presents a wide soft face to the load and a smooth one to the rigger, so it is chosen where the surface is worth more than the extra care a rope would need, and where the load is not so abrasive or so hot that the fibre is out of its depth.

Three things the name has to carry: სიგანე, figure and ends

• სიგანე — sets the pressure on the load. A narrow band concentrates the load and is the right answer on a light, stiff article; a wide band spreads it and is the right answer on anything soft, დაფარული ან დასრულებული. It also sets what the band can be folded into.
• ფიგურა, per mode — a webbing sling does not have one capacity. It has a capacity in vertical, a different one in basket and a lower one choked, and the label states each of them. Purchasing on “ტონაჟი” alone is the single most common error in this category.
• მთავრდება — flat loop, folded eye or reinforced eye; they decide how the band sits on a hook, whether it can be used in a choker, and how the last of the fibres at the end are protected. The end is where a band wears out first, so it is worth specifying deliberately rather than accepting by default.

One band, several figures: the arrangement decides the rating

ქვემოთ მოყვანილი ფიგურები არის სტანდარტული რეჟიმის ფაქტორები, რომლებიც გამოიყენება მთელ ბაზარზე ბრტყელი ქსელის სამაგრებისთვის: each is multiplied by the sling’s own marked working load limit to give the capacity in that arrangement. კუთხე არის ფეხის კუთხე ვერტიკალურთან, და სტატიის ეტიკეტი ყოველთვის აჭარბებს ცხრილს.

Two consequences worth stating plainly. A choked webbing sling is weaker than the same sling used vertically, ასე რომ, ტვირთს, რომელიც უნდა ჩაიხრჩო, უფრო დიდი ზოლი სჭირდება, ვიდრე გრძელი. და როგორც ფეხები გაშლილი, მოცულობა ეცემა, which is a geometric fact rather than a material one — it is answered by a wider angle-free arrangement, by a spreader, or by a bigger sling, და სხვა არაფრით.

Colour on the band is identification, not certification

Flat webbing slings are colour-coded by working load limit under the convention most of the market uses — 1 ტ იისფერი, 2 ტ მწვანე, 3 t ყვითელი, 4 ტ ნაცრისფერი, 5 t წითელი, 6 ტ ყავისფერი, 8 ცისფერი, 10 ტ ფორთოხალი. It is genuinely useful on a site: a rigger can spot a two-tonne band in a pile from across the yard. What the colour cannot do is replace the label, because the figure that applies is the one printed and affixed to that individual sling, and above the top of the coded range there is no colour to read at all. Treat the colour as the fast check and the label as the answer.

Replacing a wire rope: where the swap works and where it does not

The practical rule is that a webbing sling is chosen for the sake of the load, not for the sake of the sling, and the environment the band works in is the price of that choice. Where both a finished surface and an abrasive environment are present, the answer is normally a covered or sleeved band rather than a return to wire rope — but that is a decision to take with the supplier on the specific job, not a default.

აწევა, lashing and towing are three different duties

The same article is often bought for all three and should not be. They load the band differently and are rated differently, and the confusion is the reason this section exists.

Where a load has to be both lifted and held in transit, the correct answer is two articles rather than one used twice: a sling that lifts, და ა ratchet cargo lashing belt ან ratchet tie down strap that restrains. It costs less than the incident.

კიდეები, sleeves and the protection that is part of the specification

კიდეზე მოჭრილი ზოლი იწყება როგორც პატარა ჭრილი და მთავრდება მარცხით, so edge protection is a specification line rather than an accessory decision. სადაც დატვირთვას აქვს ბასრი კუთხე, დამუშავებული ტუჩი, ბურუსი, შედუღების შპრიცი ან უხეში ჩამოსხმის კანი, ან ზოლი არის მკლავიანი და ყდის არის სტატიის ნაწილი, or the corner is protected with a pad or a corner piece that travels with the band. მოითხოვეთ ეს გამოკითხვის ეტაპზე: a sleeve added later cannot be retro-fitted to a band already woven, and a band ordered without one is a band that will be used without one.

ინსპექტირება, and the conditions that end a band’s life

შეამოწმეთ ყოველი გამოყენების წინ, და ფორმალურად ინტერვალში საიტის წესები დადგენილია. The conditions that remove a webbing sling from service are specific rather than a matter of judgement: acid or caustic burns, melting or charring, სნაგები, პუნქცია, tears or cuts, broken or worn stitching, distortion of the fittings or the eyes, and a label that can no longer be read. A band with any of those is out of service, and it is out of service because the damage is in the load path, not because it looks untidy. შეინახეთ სუფთა და მშრალი, მზის შუქისგან, and keep the record with the article.

ხშირად ეკითხებოდა

Can a webbing sling really replace a wire rope of the same capacity? For the lift itself, დიახ, provided the figure is taken per hitch and the edges and the temperature are within the band’s limits. The two are not interchangeable in the environment, which is a different question from the load.

What width should I order? The narrowest width that will carry the figure without crushing the load, or the widest the load’s geometry will accept. Send the load and the figure, and the width follows.

Why is the choked figure lower? იმის გამო, რომ ზოლი დატვირთულია თავის წინააღმდეგ და შეფუთვა იჭერს, so the fibres are working in a way the vertical figure does not describe. ნორმალურია, ეს არის ეტიკეტზე, and it is the reason a choke sometimes needs the next size up.

Can I use one sling as a lashing as well? Not as the same article. Restraint is rated for continuous tension, არა ლიფტისთვის, and the two duties are marked differently. Buy the lashing as a lashing.

How long will a band last? გარემო წყვეტს, არა კალენდარი: a band on painted steel in a workshop gives years, the same band dragged over concrete and grit gives shifts. შეამოწმეთ მდგომარეობა და არა ასაკი, and never against a fixed service life.

Does the colour tell me the capacity? It identifies the working load limit by convention, and it is not a substitute for the label. Where the colour and the label disagree, or the label is unreadable, ჯგუფი არ მუშაობს.
