Lashing-chains & ratchet-tensioners.
Steel lashing-chains are characterized by their very high tensile forces and robustness. They can be used on sharp-edged loads or rough surfaces and have an impressively long service life. Lashing-chains in accordance with DIN EN 12195-3 and VDI 2700 ff are ideal for direct lashing (diagonal lashing method and diagonal lashing method) on low loaders, for example. You can buy grade 8, grade 10 and grade 12 lashing-chains, lashing-chains and ratchet-tensioners in the Dolezych store.

Buying lashing-chains: What you need to know
Our lashing-chains are available in the well-known quality classes 8 (Quality class 8), 10 (Quality class 10) and 12 (Quality class 12). They are mainly used for diagonal lashing of heavy loads. Tie-down lashing is also possible, but only with edge protectors. Our lashing-chains always comply with EN 12195-3. Our short-link chains guarantee excellent chain support for edge loads. Long-link chains would deform here. You can use shortening elements for chains or connecting elements to set the desired length. You can buy your lashing-chains for load-securing in various configurations:
1-piece lashing-chain: lashing-chain is connected to the ratchet-tensioner
2-part lashing-chain: lashing-chain and ratchet-tensioner are separate from each other
Modular lashing-chain system: These elements are available for lashing-chain systems
Lashing-chain: Device for securing loads consisting of a tensioning element and a chain with or without connecting elements
Connecting element: e.g. lashing hooks, coupling links/coupling elements, shackles
Tensioning element: Device for tensioning/applying a pre-tensioning force (e.g. multi-purpose ratchet tensioner)
End link: end fitting of a lashing-chain (oval closed link used to hook the lashing-chain into the uprights of skip containers)
Shortening element: for manually shortening the chain before the tensioning element is used (e.g. shortening hooks, shortening claws)
Lashing-chains Grade 8, Grade 10 and Grade 12
The chains can be described by the respective nominal size (NG) and grade.
Nominal size = nominal thickness in mm of an individual chain link
Grade = ratio of force per load-bearing cross-sectional area; the higher the grade, the higher the tensile force for the same material thickness
Grade 8 lashing-chains are generally manufactured in accordance with DIN EN 12195-3, round steel chains in accordance with DIN EN 818-2:2008-12. Grade 10 and 12 lashing-chains are also manufactured in accordance with DIN EN 12195-3.
Interesting: Steel chains are characterized by their robustness and high tensile forces. Unfortunately, they are often difficult to handle and can damage loads. With the DoNova® PowerLash textile lashing-chain, you have many of the advantages of a steel lashing-chain and an ergonomic and load-friendly tool.
Tensioning lashing-chains with the right ratchet-tensioner
Tensioning lashing-chains with the right ratchet-tensioner
In order to securely tension the lashing-chains for load-securing on a low-loader or other vehicle, you need the right ratchet-tensioner. Heavy loads in particular, e.g. heavy equipment in the construction industry such as an excavator, can be ideally secured with lashing-chain systems.
Important: Overtightening the spindles will damage the tensioning element! Our DoRa and DoQuick tensioners no longer have this disadvantage - they are equipped with an anti-unscrewing device that prevents damage to the spindle thread!
The longest tensioning path in the world: the DoRa ratchet-tensioner
Save energy: less tightening of the chains when hooking in
Save time: thanks to the "tensioning path reserve", the lashing-chain does not have to be completely re-tensioned when re-tensioning
Small design: can also be used in tight spaces
Longer service life: thanks to innovative & completely new visual marking & thread overtightening protection
DoQuick: Simply tension faster
Save time and energy: Thanks to the quick-release mechanism, you never have to unscrew the thread by hand again, but can pull it out completely in less than a second. Pre-tensioning is also very easy, as you can simply "push" the threaded rod into the tensioner.
Space-saving: Thanks to the very short lever, the DoQuick can be used in a space-saving manner and stowed away when not in use.
Apply force safely: The swivel eye prevents unintentional twisting of the lashing-chain - pre-tensioning forces can always be achieved.
Maximum service life: Thanks to our new innovative anti-unscrewing device especially for the DoQuick, threaded rods can never be over-twisted again.
Twice the tensioning path: Compared to a standard ratchet tensioner, the DoQuick has twice the tensioning path: attaching the chains is therefore much less strenuous, as you don't have to pre-tension the chain as much at the start.
Marking of lashing-chains
Each lashing-chain has a metal tag (or, in the case of our textile chain, a sleeve) on which the following information can be found:
- Lashing capacity (LC) in kN
- Pretensioning force (STF) in daN
- Type of lashing
- Warning: Must not be used for lifting
- Name or marking of the manufacturer
- Traceability code
- Reference to DIN EN 12195-3
Handling instructions for lashing-chains
- Only use undamaged lashing-chains
- Do not load lashing-chains beyond their LC
- Do not knot or twist lashing-chains
- Do not use lashing-chains to lift loads
- Do not place any load on the lashing-chains
- Do not stretch lashing-chains over sharp edges (use edge protection)
- Lashing-chains must be provided with a clearly legible marking
