Lifting Chains in quality class 8 according to DIN EN 818-4

 

DoKett Lifting chains are are slings according to BGR 500 (formerly UVV VBG 9 a) and meet all requirements of DIN EN 814-4 (GK8).Lifting Chain

Grade 8 is the proven quality standard for sling chains.   It is characterized by high strength, low dead weight, special joint hardening, high wear resistance and a huge range of accessories. In the universal DoKett 1 system, all components of the lifting chain can be combined with each other by means of coupling links, the DoKett 2 system is free of confusion, because it only allows connections of components of the same nominal size.

 

Sling chains DoKett 1 

 

The universal system in grade 8 is DoKett 1. By connecting the individual lifting chain components with the universal coupling link, there are virtually no limits to the variety of combinations   .   For example, very large crane hooks suspension heads in special sizes can be used with .   The combination with Stop ropesRound slings or lifting straps is guaranteed.

 

Lifting chains DoKett 2

 

With the DoKett 2 system, no mix-ups can occur during assembly with grade 8 lifting chains, as only connections of chains and components of the same nominal chain thickness and thus the same load capacities are possible .

 

Example: 
A 2-strand lifting chain with a load capacity of 2.8 t at an angle of inclination between 0° and 45° can only be assembled with so-called 8 mm (or 8s) components (8 mm suspension head, 8 mm chain, 8 mm hook, etc.) .

 

Available hook types:

When you click on the different hooks, a new tab opens with helpful information about each hook.

There you will also find other hook variants that can be combined with DoKett lifting chains!

Lifting chain with DoClick, Grade 8, DIN EN 818-4

According to the recommendation of the BG, chain shorteners must be equipped with an additional locking device or have a modified design – due to incorrect applications that have occurred and the possibility of unintentional release of the chain. 

The alternative is our DoClick hook with BG approval.

DoClick is the sling hook with integrated shortening option and safety device for sling chains in grade 8.

  • Use as hook of a chain slingDoClick hook
    The sling shortening hook is hooked into the end of each of the chain strands.
  • Use as a hook in a symmetrically shortened lifting chain 
    The stop shortening hook is hooked onto at the same height on each of the chain strands. You receive a variable length chain hanger. The now surplus, non-supporting chain is suspended with the associated fire department snap hook high.
  • Use as a shortening hook in a lifting chain
    The sling shortening hook is hooked asymmetrically at the desired height on the chain strands.   The now surplus, not carrying chain is suspended high with the associated firefighter snap hook .
  • At the recommendation of the BG, in future only hooks that have a safety catch must be used in lifting chains with shortening hooks .   The DoClick hook meets these requirements: Shortening with locking device and hook mouth safety device.

Advantage: Shortening directly in the working area, no complete lowering of the crane hook required.

Tip: For more information on the DoClick and other hooks, simply click on hooks for sling chains.

 Lifting chain with DoClick hook

 

 

 

 

 

 

 

 

 

DoClick saves components, time and costs. There is no longer a need for separate shortening hooks, coupling and connecting links , as the DoClick hook is for lifting, lashing, and shortening in one.

 

How DoClick works as a sling hook

High-strength round steel link chains according to DIN EN 818-2 (formerly DIN 5687)

 

Chains manufactured in accordance with this standard are used in many applications for slinging and moving loads. Before using a chain, the inspection stamp must be checked.

Round steel chain according to DIN EN 818-2, corrosion resistant, galvanized, grade 8

The corrosion resistance, applied in special processes, exceeds the galvanizing property.   Even these chains are then even harder in the joints than required for sling chains.   Other nominal sizes on request.
