One Way Single Ply Endless Polyester Flat Lifting Webbing Sling

A one way single ply endless polyester flat lifting webbing sling is a closed loop of flat woven polyester webbing – one ply, joined to itself, with no eye, no end and no fitting anywhere on the article. It is bought for one journey and supplied with the load rather than drawn from a sling store. Ստանդարտ միջակայք: 1 t դեպի 12 տ working load limit on 4 mm webbing, լայնություններ 25 մմ դեպի 300 մմ ժամը ա 5:1, 6:1 կամ 7:1 գործոն, loop lengths 0.5 մ դեպի 100 մ, colour coded to BS EN 1492-1 and supplied with a blue label stating the working load limit, երկարությունը, the factor and the batch.

Why a Loop Suits a One-Trip Band

The two halves of this name answer two different questions. One way is commercial: the band travels with the pack, is used once, and is not recovered or re-issued. Անվերջ is structural: the band is joined to itself, so there is nothing to thread and nothing to align.

Put together, they answer what actually goes wrong at the far end of a consignment: the person re-slinging the load has no rigging plan, no sling store and no second choice, and a loop asks nothing of them.

• Nothing to align. An eye has to meet a hook of the right size the right way round. A loop is dropped over the load or passed round it, and the pick works whichever way it lands.
• Nothing to bruise a finish. No stitching stack at the bearing point, no thimble, no shackle in contact with the load. On coated pipe, anodised section or polished sheet that is the whole protection.
• Nothing to lose. A band with fittings can arrive with the fittings gone. A loop is one piece of webbing and it is either there or it is not.
• Nothing to get wrong on length. The one exception on this list, and it is the one that matters most – see the section on length below, because a loop is quoted two ways and they differ by nearly a factor of two.

Specifications

Չափսերը: Width Follows the Figure and the Factor

Width is not a free choice: it follows from the working load limit and from the factor, which is why the same tonnage appears three times below with three widths. Ա 7:1 band is wider and heavier than a 5:1 band of the same figure – that is the cost of the extra factor, not a different grade of webbing.

The same width ladder, in the looped-end form, is published on the մեկանգամյա օգտագործման բարձրացնող պարսատիկներ էջ – useful when a consignment needs eyes at the top and a loop at the bottom, which is two articles rather than one.

Maximum length is 100 m in one continuous loop. Longer lengths, intermediate widths, extra-wide loops and special colours are made to order. Nothing in the table is a stock size: the figure, գործոնը, the width and the length together describe a band made to your line.

Two readings catch buyers out. Այն minimum length follows the width, ոչ թե տոննաժը: 25 մմ վերցնում է 0.5 մ, 50 և 75 մմ վերցնել 1.0 մ, 100 դեպի 150 մմ վերցնել 1.5 մ և 200 մմ և բարձր վերցնել 2.0 մ. Փափուկ մակերեսի համար լայն գոտի ցանկանալը նշանակում է ընդունել ավելի երկար նվազագույնը, որը կարճ փաթեթում այն ​​գիծն է, որը որոշում է կարգը. Իսկ weight column is a handling figure: հարյուր մետրանոց սանդուղքի վերևում 300 mm band is over a quarter of a tonne, և խմբերը ճանապարհորդում են որպես բեռ, նախքան որևէ բան բարձրացնելը.

Երկարություն: the Two Conventions, and Why It Matters More Here

A loop has no ends to measure between, so this trade quotes the same article two ways: որ շրջապատ of the loop, և length of the band laid flat. For the same sling the two figures differ by about a factor of two. Both are legitimate; only one of them is the figure you meant.

On a reusable sling the mistake shows up at the next lift and is corrected from the store. On a one-way band it shows up at the far end, in front of a customer, with no second band to swap in – which is why this is the single line worth getting right on the enquiry. State the convention with the figure, or state the use instead (the girth of the article the loop must go round), and the ambiguity disappears before the band is cut.

The Three Hitches, and What Each One Carries

The same loop works in three arrangements, and the figure on the label only describes the first of them. This is the most common error on an endless band, because all three are rigged without any change to the article.

The choke is the arrangement a loop is bought for – it is what grips a pipe, a pole or a drum – and it is also the one that costs 20 % of the figure. Այսպիսով, ա 4.5 t pipe bundle choked on a 5 t loop is an overload, not a margin, and the answer is the next width up rather than a longer band. Where the loop is used as a basket under a bundle, both sides carry and the figure doubles; where it is used vertically, the label figure applies as printed.

One Way Is a Commercial Life, Not a Lower Grade

The word describes the journey, և ուրիշ ոչինչ: մանրաթելը, հյուսել, լայնությունը, գործոն, working load limit and marking are specified exactly as for a band used for years, and buying a narrower band or a lower factor because it is only going one way is not a saving – դա վերելակից հանված չգնահատված մարժա է. What does change is the record. On a reusable sling the inspection history is the evidence; on a single-trip band there is no history after the lift, այսպես the print on the band and the packing list carry the whole traceability. The returnable version of the same loop, inspected between lifts and drawn from a store, է միաշերտ անվերջ հարթ պարսատիկ.

• Marking is part of the specification, not the paperwork. Աշխատանքային բեռի սահմանաչափը, երկարությունը, գործոն, և հղումը, որն իրականում օգտագործում է առաքումը – փաթեթի համարը, an order number, your own part number. That reference is what ties a band on a quay to a line on a packing list in an office.
• Ընթեռնելի է ճանապարհորդությունից հետո, ոչ արտադրությունից հետո. Ֆիգուրները պետք է գոյատևեն բեռնատարով, կոնտեյներ և բեռնման վայր. Տպագիր, որը փոքր է, low-contrast, or on a face that enters the choke is print that will not be read.
• Գույնը որպես երկրորդ ալիք. Մեկ գույն մեկ փաթեթի տեսակի համար, մեկ հաճախորդի կամ մեկ տոննաժի հաշվով նույն ժապավեններով բեռնարկղը վերածում է մի բանի, որը կարելի է տեսակավորել մի հայացքով, and on a made-to-order band it costs nothing.

Counting: One Band per Pick Point, per Pack

One-trip bands are bought in the same arithmetic as the packing, and it is done once because nothing comes back. Հաշվեք փաթեթից, ոչ թե տոննաժից: two picks per pack is two bands, չորս կետանոց վերելակը չորս է, and ninety packs at two picks is 180 նվագախմբեր. Դիտմամբ ավելացրեք բեռնաթափման նպաստը – two to five per cent covers the band cut on a sheet edge while the pack is made up – so a shortfall becomes a line on the order instead of a delay at the dock. Where the bands are packed inside a crate, strapped to a stillage or taped into a bundle, the sling becomes a line on the bill of materials: մասի համարը, a loop length, a colour and a print that does not change between shipments.

Where a One-Trip Loop Is the Right Order

The Single Inspection, and What It Looks At

A one-trip band has one inspection in its life and it happens before the load, երբ անսարքությունը դեռ կարող է փոխարինվել նույն խմբաքանակից. Չորս բան է դիտարկվում, այս կարգով: the weave where it meets the load (կրճատումներ, քայքայում, a glazed or pinched face), the join where the loop closes, the label – because an unreadable figure cannot be matched to the pack it was cut for – and what the band has been lying in. Մռայլ, թզուկ, նավթը և մշտական ​​ջուրը անցնում են շփման մեջ, and a clean band is the cheapest protection on the list.

Պաշտպանեք այն սուր եզրերից, hot surfaces and welding spatter with a sleeve or a padded protector, never shorten a sling with a knot, never join two slings by knotting them, and never repair webbing by stitching, welding or heating. At the destination the band is disposed of, չի պահվում: a one-trip band that comes home to a rack gets issued again, and its marking then states something that is no longer true.

Հաճախակի տրվող հարցեր

What is a one way single ply endless polyester webbing sling?

A closed loop of flat woven polyester webbing, one ply thick, joined to itself with no eye, no end and no fitting. It is bought for one journey, supplied with the load and not recovered. The standard range runs 1 t դեպի 12 t on 4 mm webbing, 25 մմ դեպի 300 մմ լայնությամբ, with loop lengths from 0.5 մ դեպի 100 մ.

How is the length of an endless sling loop measured?

Two ways, and they differ by about a factor of two: the circumference of the closed loop, and the length of the band laid flat before joining. Անվանեք կոնվենցիան, or name the girth of the load instead – that is the form that leaves nothing to interpret.

Is a one-trip endless band weaker than a reusable one?

Ոչ. Width follows the working load limit and the factor in exactly the same way, իսկ ժապավենի վրա տպված թվերն այն թվերն են, որոնք վերաբերում են վերելակին. What changes is that the band is not recovered, so the print and the packing list carry the whole record of it.

Which safety factor should I order – 5:1, 6:1 կամ 7:1?

7:1 is the design factor used for general-purpose flat woven webbing slings under European practice and is the usual choice with colour coded bands under BS EN 1492-1. 5:1 is the customary North American figure for synthetic webbing slings and 6:1 նստում է նրանց միջև. Նույն տոննաժը տարբեր գործակցով տարբեր լայնությամբ տարբեր հոդված է, ուստի գործոնը պետք է լինի հարցման վրա.

Can an endless webbing loop be used in a choker hitch?

Այո՛, and it is what a loop is best at – it is how a pipe, a pole or a drum is gripped. Խեղդված գործիչն է 0.8 of the vertical figure, ուրեմն ա 5 t loop chokes 4 տ. Select the width for the arrangement you will really use, not for the vertical figure on the label.

Single ply or double ply endless sling?

Single ply is the lighter, more flexible and more economical build, and it is the right answer for most lifts up to 12 t and for anything that has to be threaded through a tight space or wrapped round a small diameter. Double ply buys a higher figure at the same width, or a stiffer, wider bearing face – at more weight and more cost per band.

Can the band be printed with our own reference or packed with our product?

Yes to both, and they are usually ordered together. Աշխատանքային բեռի սահմանը, the loop length and your own pack, order or part number can be printed as a production instruction, in the exact string and case you send; the bands can be packed inside a crate, strapped to a stillage or taped into a bundle, labelled per pack and listed on the packing list with the reference that matches the print.
