Lift sling rigging company produce 50MM 5000kg Ratchet Lashing Belt Ratchet Tie Down Straps,50mm Cargo Lashing Belt,5 Tonne Ratchet Strap,50mm Ratchet Lashing Strap – LC 2500daN (안에 12195-2),50mm 5000 Kg Ratchet Tie Down Lashing Straps With J-hook.
50mm 5000kg Ratchet Lashing Belt — Ratchet Tie Down Straps
This is the size most buyers end up with: 에이 50 mm 5000 kg ratchet lashing belt — 2 inch polyester webbing, a forged ratchet buckle and a hook at each end, rated at a lashing capacity of LC 2,500 그리고 and a minimum breaking strength of 5,000 그리고. Standard tension force is 350 daN at a hand force of 50 그리고, and the assembly is built and marked to EN 12195-2.
It is the middle of the range and the reason is arithmetic rather than fashion. 25 mm 그리고 35 mm belts are cheap but narrow: they concentrate the load, they run out of strength on anything above a van, and the buckle a narrow band needs is fiddly in gloves. 75 mm 그리고 100 mm belts carry twice as much, and they are also twice as awkward on a load bed, twice as heavy in the hand and twice the price. 그만큼 50 mm sits where the strength is enough for a flatbed, a container or a plant trailer, and the band is still easy to throw over a load and pull through.
What “50mm 5000kg” Actually Means
Three different numbers get sold as “5000kg”, and only one of them describes what the strap may do in service. The sequence below is the one that matters at the counter.
| 수치 | Value on this assembly | What it describes | How a buyer misreads it |
|---|---|---|---|
| 최소 파괴 강도 (MBL) | 5,000 그리고 (5,000 kg) | 당김 테스트에서 어셈블리가 실패하는 하중 | Read as the working figure — this is the mistake that overloads a trailer |
| 래싱 용량 (LC) | 2,500 그리고 (2.5 티) | The restraint the assembly is rated to hold, 라벨에 표시된 | Compared against a lifting sling’s WLL, which is a different duty |
| 표준 인장력 (STF) | 350 그리고 ~에 50 daN hand force | The tension one person reaches with the ratchet | Confused with LC, so the operator keeps winding past the useful point |
If you are comparing quotations for 50 mm 래칫 타이 다운 스트랩, ask for the breaking strength in daN and the LC separately, and ask which one the price was quoted against. Two suppliers quoting “5 tonne” can mean the breaking strength and the working figure, and the difference is a factor of two.
EN 아래 12195-2 the webbing of a lashing strap must reach at least twice its lashing capacity, which is where the 2:1 relationship comes from: 2,500 daN of rated restraint, 5,000 daN before anything breaks. A North American catalogue will often print the same article as “10,000 lb” because it quotes breaking strength in pounds. Same belt, different unit — and a genuine trap when two quotations are compared side by side.
Technical Parameters of the 50mm 5000kg Belt
테이블은 표준 빌드입니다.. 길이, end fitting, colour and marking are fixed on the order, because the rating applies to the finished assembly — band, stitching and hardware together — not to the roll of webbing it came from.

그만큼 50 mm advantage is not only strength. 에이 50 mm band spreads the same preload over twice the area of a 35 mm 밴드, so it crushes a carton, a painted panel or a soft bag far less at the same tension. That is why buyers move up a size for the load’s sake rather than the rating’s.
Attachment Parameters — Buckle, Hooks and End Fittings
The band is the cheap half of the assembly and the fittings are what the buyer is really choosing, because they decide whether the strap fits the vehicle in front of them. Every item below is supplied on a 50 mm belt to your length, or on its own as a spare.

Ratchet buckle
The short-lever ratchet is the standard 50 mm buckle: one gloved hand, a pawl that holds what has been gained, and a drum that winds a few centimetres per stroke. The long aluminium lever trades speed for tension — it reaches the 350 daN STF in fewer strokes and it is the version specified where the operator is working in gloves, at height or in the wet. The buckle is a lever and a winch at once, and the number it produces is the STF on the label, not the LC. Grit in the pawl, a bent lever and a drum that no longer turns freely are the three ways it ends its life early.
후크, and why the anchor decides
Specify the anchor point rather than the hook. A double-J with a closed throat for a lashing point or a container fitting; 로드 베드 가장자리용 플랫 후크, because it sits flat and marks the deck least; a vinyl-sleeved S-hook for a ring on light duty. A hook sitting half in its point is the commonest reason a lashing comes loose, and it lets go under braking — which is the moment the strap was bought for. Rings, shackles and the hardware that takes a belt end are on the 리프팅 장치 페이지.
Endless and ring ends
With no hook at all, the belt is passed around the load and tensioned against itself — the configuration a bundle or a pallet needs, and the one that lets a single strap serve several load shapes. A ring end does the same job but leaves a hard point for a shackle or a second belt. Both keep the assembly’s rating, because the band and the stitching are unchanged; only the hardware is missing.
Five Ways the Assembly Is Configured
| Code | 종료 | 표준 길이 | 다음에 가장 적합 | Watch out for |
|---|---|---|---|---|
| CLB-50-J | Double-J hook both ends | 6 중 / 8 중 | 평판, 컨테이너, plant trailer — the default | Hook must sit fully in the point, not half in |
| CLB-50-F | Flat hook both ends | 6 중 / 8 중 | Load bed with a rail or a lip | Rail must be rated, not a body panel |
| CLB-50-R | Ring both ends | 6 중 | Shackle take-off, two belts to one point | Ring is the weak point if undersized |
| CLB-50-E | 끝없는, no hook | 3 중 / 5 중 | 번들, 팔레트, pipe and timber packs | Needs a friction surface or an edge sleeve |
| CLB-50-ET | E-track fitting one end, hook the other | 5 중 / 6 중 | Track-equipped deck or van floor | Track rating often below the belt’s LC |
| 길이 | Strap weight | Reach after buckle and hooks | Typical job |
|---|---|---|---|
| 3 중 / 10 피트 | ~0.7 kg | ~2.4 m | Short drops, machinery on a small trailer |
| 5 중 / 15 피트 | ~1.0 kg | ~4.4 m | Vans, car transporters, single pallet |
| 6 중 / 20 피트 | ~1.2 kg | ~5.4 m | The standard flatbed and container length |
| 8 중 / 27 피트 | ~1.5 kg | ~7.4 m | Long loads, 재목, double-stacked pallets |
| 10 중 / 33 피트 | ~1.9 kg | ~9.4 m | 갑판 화물, oversize plant, ro-ro |
What Makes a Genuine 5,000 kg Belt — the Weakest Link
Every part of a lashing is rated, and the assembly is rated at the lowest of them. A supplier who quotes 5,000 kg from the webbing alone has quoted a number that does not exist in the box.
밴드
50 mm high-tenacity polyester reaches roughly 5,000 daN at 1.8 mm thickness when the weave is dense and the yarn is specified by minimum tenacity. Cheaper band is thinner, lighter and reaches the same width with less strength — it also elongates further, which lets the load walk and then shocks the system when it catches. Ask for the band mass per metre: 88 g/m is this build, and a figure much below it is a different belt.
The stitching
The stitch is a load path, not a seam. 에이 50 mm belt carries a box-X pattern in high-tenacity polyester thread at every hook and buckle, with the run stitched in the same thread at a set pitch. 고장난, worn or pulled stitching at the ends is a retirement condition, not a repair — a restitched belt has no rating unless the maker re-tests it.
The hook
The hook’s minimum breaking strength has to be at or above the assembly’s, 그렇기 때문에 50 mm J-hook is forged rather than stamped. A stamped hook on a 5,000 daN band is the single most common way a cheap belt fails: the band survives, the hook opens.
The ratchet
프레임, the pawl and the drum all see the full tension. Zinc-plated forged steel is the material for this rating; the aluminium in a long-lever buckle is the handle, not the frame. A ratchet that lets go under vibration gives no warning from outside the drum, which is why a worn pawl spring is a retirement condition.
How to Check a 5,000 kg Strap on Arrival
- 라벨 읽기, not the listing. LC 2,500 daN and STF 350 daN must be printed on a sewn label with the length, 너비, maker and batch. A sticker is not a label.
- Weigh one strap. 에이 6 중 50 mm assembly of this build is about 1.2 kg. A strap that is half the weight is a thinner band with the same colour.
- Measure the band. 50 mm ± 2 % 넓은, 1.8 mm thick at the edge, and the weave should be dense enough that you cannot see daylight through it.
- Look at the hook. Forged hooks have a parting line and a solid throat; stamped hooks are folded sheet and open under load.
- Ask for the pull-test record. It is the one document that ties the figure on the label to the batch in the carton.
One more check that costs nothing: pull the strap through your hands and look for a splice, a heat-sealed join or a colour change mid-length. Band is woven in a continuous run and should never be joined.
Using a 5T Belt: 짐, Angle and Friction
에이 2,500 daN belt does not restrain 2.5 tonnes of cargo by itself, and the arithmetic is worth doing once so the number of straps stops being a habit. A load is held against acceleration in three directions and the forward case is normally the worst: most road markets size a lashing at around 0.8 g.
Worked on a 5,000 kg load on a steel deck with a friction coefficient of about 0.3, lashed top-over at 60 갑판까지의 각도, the standard relation gives:
- Forward force to be held: 5,000 × 0.8 × 9.81 ≒ 39,240 N, or about 3,924 그리고.
- Friction already helping: 0.3 × 5,000 × 9.81 ≒ 14,715 N, ~에 대한 1,472 그리고.
- Residual to be carried by the lashings: ~에 대한 2,452 그리고 of tension at the deck.
Each 50 mm belt contributes a vertical clamping component of 2 × STF × sin 60°, 대충 606 daN per belt, and that clamping force turns into friction at the deck. Five belts is the practical answer at 60 degrees — four on a timbered deck, six or more on wet aluminium, which is exactly why the count is a calculation and not a rule of thumb. Anti-slip mats under the load buy more restraint than another half-turn on the handle.
Lengths, Sets and Packing
On a ratchet tie down strap the packing is half the specification and most of the buying decision. A two-piece set with a printed header card is the retail norm for trailer work; a four-piece set is the DIY pack; 유통업체가 가져간다 10 또는 20 판지에 결박, 줄무늬, with the LC and the length on the outside. The sewn label is the part that cannot be changed after the fact: 당신의 브랜드, 당신의 부품 번호, LC 2,500 daN and STF 350 daN in the unit your market reads, 시스템에 필요한 경우 배치.
For the container and flatbed trade the same belt is often bought as a 6 m single with a short lever and a J-hook, because that is the length that reaches from a deck ring over a pallet and back. If you are buying a mixed order, this is the size to standardise on: 한 길이, 후크 하나, one label, 그리고 25 mm 그리고 75 mm become the exceptions rather than the rule.
돌봄과 은퇴
- Cuts and nicks at an edge. 밴드가 손상된 가장자리에서 안쪽으로 파손됨; a nick reaching the warp is the end of the strap.
- Glazed or stiff fibre. Heat or chemical contact changes the yarn before it looks worn.
- Broken or worn stitching at a hook or buckle.
- A bent or opened hook — once an S-hook has opened it will open again under a smaller load.
- 마모된 래칫 — a pawl that no longer snaps, a weak spring, a drum that drags.
- 읽을 수 없는 라벨. Without the LC the belt cannot be matched to a load.
코일로 보관, 깨끗하고 건조하다, 바닥에서 떨어져 있고 햇빛이 닿지 않는 곳에; 물과 중성 세제로 세탁하세요, 결코 용해력이 없다. 에이 50 mm belt left on an open trailer for a season is not the belt that was delivered — polyester takes UV better than polypropylene, but it still fades, 닳아 보이기도 전에 굳어지고 힘을 잃습니다..
자주 묻는 질문
What does 5000kg mean on a 50mm ratchet lashing belt?
It is the minimum breaking strength of the assembly — 5,000 kg, 또는 5,000 daN — which is twice the lashing capacity. The figure the belt may be used at is LC 2,500 그리고, ~에 대한 2.5 tonnes of restraint. Nothing in this range is rated to lift 5 톤.
Is a 50mm 5000kg strap the same as a 2 inch 5000 lb strap?
아니요. 50 mm is the same width as 2 inch, 하지만 5,000 kg is about 11,000 lb — roughly double a 5,000 lb strap. Compare the unit before the price: 에이 50 mm belt sold in North America is often quoted at 10,000 lb breaking strength, which is the same article as this one.
What is the lashing capacity of a 50mm ratchet strap?
LC 2,500 daN for this build, which is 2.5 tonnes of restraint in the tensioned band. EN 아래 12195-2 the webbing must reach at least twice the LC, so the assembly is break-tested above 5,000 그리고.
How much tension can one person put in with the ratchet?
에 대한 350 daN at the standard hand force of 50 daN on the handle — the STF printed on the label. Tension beyond that crushes the load and preloads the hooks without adding useful restraint.
Which hook should I order?
Match the hook to the anchor point: a double-J with a closed throat for a lashing point or container fitting, 로드 베드 가장자리용 플랫 후크, a ring where a shackle has to take off, or no hook at all for a bundle lashed against itself.
얼마나 5 tonne straps do I need for a 5 tonne load?
The mass is the start of the calculation, 대답은 아니다. ~에 0.8 g forward and a friction coefficient of 0.3, 에이 5,000 kg load needs the tension from about five belts at 60 갑판까지의 각도; a timbered deck or anti-slip mats reduce the count.
Can the same belt be used for lifting?
아니요. A ratchet lashing belt is marked in LC and STF and rated for continuous tension in transit. Lifting needs a 폴리에스터 웨빙 슬링 with a working load limit per hitch and a 7:1 safety factor — a different article with a different label.
Do you supply test certificates and private label?
예. Each production batch carries a pull-test record for the assembly, and the sewn label can carry your brand, part number, LC and STF. Packing is poly bag and header card, two-piece set, colour box or bulk carton.
