1. A lifting net is an assembly, not a catalogue item
A lifting net is an assembly rather than a catalogue item. It consists of a mesh panel, a border rope, edge reinforcement, lifting points or attachment fittings, and the shackles or links that connect it to the hook or a spreader beam. Each part shares the load, so the capacity belongs to the combination: two nets with the same panel dimensions can carry different loads.
Nets are therefore usually made to measure rather than stocked. Mesh opening, panel size and lifting configuration follow the cargo, so a net built to retain bagged aggregate is a different net from one built for stacked steel plate.
In this guide, "lifting net" means a net that carries a load on a crane hook. A cargo securing net restrains a load during transport; it is a different product family, covered in section 8.
2. What "rated capacity" means for a net
Rated capacity, or WLL, is the maximum load the complete assembly is designed to carry in the suspension configuration it was built for. Two things about that definition cause most of the arguments.
The figure belongs to the assembly, not to a mesh area. A capacity quoted per square metre means nothing, because the border rope and the lifting points carry the load with the mesh. It also belongs to a named configuration: the same net hung from two points and from four points is two different load cases, with different forces in each leg.
The figure is never multiplied by the number of lifting points. A four-point net is not four times a two-point net. Adding points spreads the load and changes the leg angles, and both change the force in each leg. This is the most common misreading of a net certificate, and it turns a correctly rated assembly into an overload on paper.
3. What the standards cover, and what they leave to the order
No single product standard certifies a lifting-net assembly. Slings, by contrast, are well covered: EN 1492-1 for flat woven webbing slings, EN 1492-2 for roundslings, and ISO 18264 for HMPE sling assemblies.
For nets, EN 1492-1 is frequently cited only as the test-method reference for the webbing used in the mesh. It does not define a net assembly, its lifting points, its suspension configuration or its marking. Cargo securing nets belong to a separate family, covered by EN 12195-1 and EN 12195-2.
So a "certified to standard X" label on its own proves little here. The rating basis, the test regime and the marking have to be agreed when the net is ordered, then verified against the delivery.
What to specify instead: name the webbing test methods you want applied, require the design to a stated safety factor for a stated configuration, and require the finished assembly to be load-tested as a unit, with the result in writing.
4. How the rating is established: design, then verification
The maker designs the assembly for the intended suspension configuration (leg angle, number of legs, panel size, mesh, border rope) and calculates the force in each leg and in the border rope for the required working load, with a stated design factor applied.
Verification is normally by type or batch testing rather than proof-loading every net. A representative assembly from the design, or a sample from the production batch, is proof-load tested to confirm the design, and the result is recorded against that design or batch.
What matters then is the design and test record: which configuration, which load was applied, on what date, and against which batch. A certificate that states a capacity without naming the configuration cannot be checked against a lift plan.
5. Suspension geometry: why one net can have several limits
How a net hangs changes what it can carry. The variables below change the force in each leg and in the border rope, and therefore the serviceable limit, even when the net itself is unchanged.
| Variable | Why it matters | What to confirm |
|---|---|---|
| Leg angle from vertical | As the legs move away from vertical, the force in each leg rises for the same load | The angle range the rating assumes |
| Number of lifting points | More points spread the load; they do not raise the assembly rating | That the rating covers the configuration you will actually rig |
| Load distribution | A load bearing on one area puts more force into that mesh zone and the border rope | Whether the rating assumes an evenly distributed load |
| Spreader beam or frame | A frame changes leg angles and can reduce the force per leg | Whether the rating is for a framed rig or a direct hook-up |
| Number of nets | Two nets used together do not automatically double the capacity | A documented multi-net configuration, if you intend to use one |
Configuration is not optional on the certificate: "WLL 5 t" on its own cannot be checked against a lift plan.
6. Mesh opening and load retention
Mesh opening follows the smallest item in the load. The opening has to be small enough to retain it, with allowance for the mesh stretching under load and for the fabric settling into position, and it should be confirmed against that item before production starts.
A finer mesh retains more, but adds weight and reduces drainage and airflow. A coarser mesh is lighter and cheaper, and suits loads whose smallest piece is still larger than the opening. Which one is right depends on the cargo, not on a preference for fine or coarse weave.
7. What the certificate and marking should state
With no product standard to fall back on, the paperwork carries the compliance.
| Item | Why it matters |
|---|---|
| Rated capacity and the configuration it applies to | Without the configuration, the figure cannot be checked against the lift plan |
| Design factor used | Shows the margin the rating was built on |
| Unique identification per net | Links the physical net to its record through its service life |
| Batch or production reference | Groups the net with the assemblies that were tested |
| Test reference: type or batch test, date, load applied | Shows the verification step actually happened |
| Mesh specification and panel size as supplied | Lets a replacement match the original |
| Date of manufacture | Starts the inspection and record-keeping clock |
| Webbing batch material traceability | Underpins the strength claim at material level |
Certificates most often fail on one line. Everything else can be in order, and the document is still unusable if nobody can tell which rig the capacity belongs to.
8. Lifting nets and cargo securing nets are not interchangeable
The two families look similar and are often confused, but they do different jobs and are rated on different bases.
| Lifting net | Cargo securing net | |
|---|---|---|
| Purpose | Carries the load on the hook | Restrains a load during transport |
| Rating basis | Rated capacity per assembly, for a stated configuration | Lashing capacity (LC), typically in daN, under EN 12195-1 / EN 12195-2 |
| Used on | Cranes and rigging operations | Trailers, containers, flatbeds, marine transport |
| Interchangeable | No | No |
A cargo securing net must never be used to lift. The two products are engineered for different load directions and different failure modes, and a lashing capacity in daN is not a lifting capacity in tonnes.
9. Inspection and discard
Inspection follows the same principle as for slings: a documented periodic inspection by a competent person, plus a check before each use.
- Border rope: chafe, broken or pulled yarns, splice integrity.
- Mesh: cuts, abrasion, localised damage that changes the panel shape, tear propagation from a damaged cell.
- Webbing: UV degradation, chemical staining, embrittlement.
- Fittings: deformation, wear, correct assembly.
Retire the net on any of: exposed or broken load-bearing yarns, a damaged or repaired border rope, mesh damage that has altered the panel geometry, deformed hardware, or heat or chemical damage. A net whose service history cannot be established should also be withdrawn.
10. FAQ
Is a lifting net the same as a cargo securing net?
No. A lifting net carries the load on a crane hook and is rated as an assembly for a stated configuration. A cargo securing net restrains a load during transport, is rated by lashing capacity in daN under EN 12195-1 and EN 12195-2, and must never be used for lifting.
Which standard is a lifting net certified to?
There is no single product standard that covers a lifting-net assembly. EN 1492-1 is commonly cited as the test-method reference for the webbing in the mesh, but it does not define the assembly, its lifting points or its marking. The specification, the design factor, the test regime and the marking therefore have to be agreed in the order and verified on delivery.
Can the capacity be increased by adding lifting points?
Lifting points share the load; they do not multiply the rating. Adding points changes the load distribution and the leg angles, and both change the force in each leg, so the assembly has to be rated for the configuration you intend to use.
Is every lifting net proof-load tested?
Not usually. Verification is by type or batch testing on representative assemblies, so an individual net does not have to be proof-loaded, provided the design and test record covers that assembly and batch. If a project wants every unit proof-loaded, that requirement belongs in the order.
Can a lifting net be used to lift people?
They are built for general-purpose lifting of goods. Lifting people requires equipment designed and certified for it, with different documentation and a different inspection regime.
How do I choose the mesh opening?
Work backwards from the smallest item the load could shed. The opening has to be small enough to retain it, with allowance for stretch and settling under load, and the proposal should be confirmed against that item before production.
