あ ウェビングスリング is a flat band woven from high-strength synthetic fibre, with an eye or a loop formed at each end, used in place of a wire rope wherever the load must not be marked. The band is wide and flat, so the same load is carried over a large area instead of on a point: that is the whole reason this article exists, and it is why it is the first choice on machined faces, 描いた作品, coated tube, polished sheet and anything already finished before it is lifted.
Handling it is part of the argument too. It weighs a fraction of a wire rope of the same figure, it does not kink or develop meat hooks, and it cannot cut a hand. 何が解除されるのか教えてください, the figure you need and how it will be hitched — vertical, basket or choked — and we will confirm the width, 長さ, the end configuration and the marking before the band is woven.
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. あ ウェビングスリング 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: 幅, figure and ends
- 幅 — 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, コーティングまたは仕上げ済み. It also sets what the band can be folded into.
- 形, 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 “トン数” alone is the single most common error in this category.
- 終わり — 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
以下の図は、フラット ウェビング スリングの市場全体で使用されている標準モード係数です。: それぞれにスリング自体にマークされた使用荷重制限を掛けて、その配置での容量を算出します。. 角度は垂直に対する脚の角度です, and the label on the article always overrides the table.
| 配置 | モード係数 | 床の上でそれが意味するもの |
|---|---|---|
| 垂直 | 1.0 | 片足, まっすぐに. バンドは吊り下げて持ち運べます. |
| 窒息した | 0.8 | The band goes round the load and back through its own eye. The wrap grips the load, and the band is loaded against itself. |
| バスケット, 0–45° | 2.0 | 負荷がかかったバンド, both ends on the hook, 脚が垂直に近い. |
| バスケット, 45–60° | 1.4 | 足を広げたバスケット; スプレッドコスト容量. |
| 二本足, 0–45° | 1.4 | 1 つのフックに 2 つのバンド, 脚が垂直に近い, 負荷分散. |
| 二本足, 45–60° | 1.0 | 足を広げた同じペア - 同じ容量の損失. |
| 3本足と4本足, 0–45° | 2.1 | 3本か4本の足; note it is not three or four times the figure, because the load rarely shares evenly. |
| 3本足と4本足, 45–60° | 1.5 | The same arrangement spread. Re-check rather than assume. |
Two consequences worth stating plainly. A choked webbing sling is weaker than the same sling used vertically, so a load that must be choked needs a bigger band rather than a longer one. And as the legs spread the capacity falls, 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, and by nothing else.
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 バイオレット, 2 グリーン, 3 黄色, 4 グレー, 5 赤, 6 ブラウン, 8 青, 10 オレンジ. 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 condition | ウェビングスリング | ワイヤーロープスリング |
|---|---|---|
| Finished or painted surface | The reason to choose it: wide soft contact, マーキングなし. | Marks and scuffs the surface; needs padding to compete. |
| Weight to be handled | A fraction of a rope of the same figure. | 重い, stiff, and awkward above a certain size. |
| Sharp edges and burrs | Requires an edge protector or a sleeve, without exception. | Copes with much more, which is why it still owns the fabrication yard. |
| Hot surfaces and hot work | These fibres have a working limit around 100 °C and fail by melting, not by deforming politely. | Far more tolerant, though not unlimited. |
| 摩耗, グリット, dragging over concrete | Wears quickly; the cover can be added but the band’s life is measured in shifts. | The better answer where the environment itself is the attack. |
| Chemical contact | Depends on the fibre; acids, caustics and some solvents are hostile to most of them. | Steel is indifferent to most of what destroys a band. |
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.
リフティング, 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.
| 義務 | How the band is loaded | 何で評価されるべきなのか | What must never happen |
|---|---|---|---|
| リフティング | 簡単に言うと, 目に見えて, with a person watching and a standing load. | A lifting rating, stated per hitch and per angle, with the marking that goes with it. | A band bought for restraint used to lift. |
| Lashing / restraint | 継続的に, 緊張した状態で, 輸送中, 無人, with fatigue and vibration. | A restraint rating — a lashing capacity, tensioned by a ratchet or a buckle, not a lifting rating. | A lifting sling used as a lashing, or a lashing used as a sling. The duties do not transfer. |
| Towing and recovery | In snatch loads: repeated shock, far above the steady figure, plus elastic recoil if anything parts. | A purpose-made tow or recovery strap, built for shock loading, with its own rating and its own safe practice. | A lifting sling, or even a plain lashing, used as a tow rope. This is a fatal-practice, not a marginal one. |
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, そして ratchet cargo lashing belt または ratchet tie down strap that restrains. It costs less than the incident.
エッジ, sleeves and the protection that is part of the specification
エッジによってカットされたバンドは小さなノッチとして始まり、失敗として終わります, so edge protection is a specification line rather than an accessory decision. 積荷の角が鋭利な場所, 機械加工されたリップ, バリ, 溶接スパッタまたは粗い鋳肌, バンドがスリーブ付きであるか、スリーブが商品の一部であるかのどちらか, or the corner is protected with a pad or a corner piece that travels with the band. お問い合わせの段階で聞いてください: 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.
検査, and the conditions that end a band’s life
毎回使用前に点検してください, and formally at the interval the site rules set. The conditions that remove a webbing sling from service are specific rather than a matter of judgement: acid or caustic burns, melting or charring, 障害, パンク, 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. Store clean and dry, 日光の当たらない場所で, and keep the record with the article.
よくある質問
Can a webbing sling really replace a wire rope of the same capacity? For the lift itself, はい, 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? バンド自体に負荷がかかり、ラップがグリップするため, so the fibres are working in a way the vertical figure does not describe. それは正常です, ラベルに書いてあります, and it is the reason a choke sometimes needs the next size up.
Can I use one sling as a lashing as well? 同じ記事ではありません. Restraint is rated for continuous tension, リフト用ではありません, and the two duties are marked differently. Buy the lashing as a lashing.
How long will a band last? 環境が決める, カレンダーではありません: a band on painted steel in a workshop gives years, the same band dragged over concrete and grit gives shifts. 年式ではなく状態をチェック, 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, the band is out of service.
