Main catalogue version 1

 
 
1-1 Lifting_Means_System_Main_catalogue_

Always a nominal thickness lower than grade 8.

RUD chains made from patented ICE-Material can substitute grade 8 chains of the next highest nominal thickness thanks to their extremely high strength. The decisive advantage: An ICE-Lifting mean or lashing chain is more than 30 percent lighter and the working ergonomics are noticeably improved

Higher WLL with the same diameter.

RUD chains and components of grade 10 (VIP) offer up to 30 percent higher WLL than grade 8 with the same chain diameter. This means that VIP-Chains from 20 mm upwards are always one nominal thickness thinner, while their weight is reduced by up to 50 percent

TRADITION MEETS FUTURE.

Time and again, RUD is at the forefront of important developments. Many things considered standard today for lifting and lashing originated from RUD’s think tank. In 1953, RUD was the first chain manufacturer to receive the inspection stamp H1 for high-strength chains, in 1972 it was the first to receive approval for grade 8 (H1-8) and in 2007 for round steel chains of the highest grade 12 (D1-12) (ICE). To simplify test processes, we have long equipped many products with RFID transponders as standard and offer a complete hardware and software system for efficient test management. The latest milestone: In 2019, RUD presented the first lifting point that “thinks” and can thus avoid dangerous transverse loads. There is still a lot for us to do, join us into the future.

AWARD-WINNING SERVICE.

Numerous awards prove it: RUD’s innovative strength and performance are outstanding – in the industry and beyond

WHAT IS A CHAIN SUSPENSION IN ACTUAL FACT?

In the world of lifting means, chain suspensions form the connection between the sling and the load. It consists of several components. Suspensions can be purchased fully configured – depending on the weight, size and shape of the load.

 

Components of a suspension are:

 

  • Master link

  • Chains (in one or several strands)

  • End component (e. g. hooks)

  • Any connecting elements (to connect two chains)

  • Any shortening elements (to shorten chains)

  • Any further elements (e. g. balancer)

OPTIMAL CONFIGURATION OF CHAIN SUSPENSIONS.

FROM THE MASTER LINK TO THE FINAL COMPONENT:
WHAT YOU SHOULD CONSIDER.

From the master link to the final component: Configuring chain suspensions is full of challenges. Safety and efficiency are the top priorities for us. As a globally recognised specialist in the field of lifting and moving loads, we support you in your daily lifting tasks. With our ICE- and VIP-Construction kits, for example, we have created the basis for ensuring that RUD components with different WLL cannot be accidentally combined. On these pages, you will learn how to configure your individual suspension optimally for your respective applications.

 
1-1 Lifting_Means_System_Main_catalogue_

WHICH REQUIREMENTS DOES A CHAIN SUSPENSION HAVE TO FULFIL?

Approval.

The standards DIN EN 818, DIN EN 1677 and E DIN 21061 guarantee a maximum of safety in the manufacture of chains. Lifting means that are approved and tested in accordance with these international standards are authorised by the German Social Accident Insurance (DGUV) to bear the so-called H-stamp. Do you value quality and safety? Then check whether your lifting means has an H-stamp.

Identification.

Furthermore, every lifting chain has an identification tag from the manufacturer, which must be permanently fixed to the chain. Among other things, it provides information on the WLL, the nominal diameter and the grade. If this tag is missing, you must not use the chain, since important characteristic values of the chain and thus of the suspension cannot be determined. VIP- and ICE-Identification tags from RUD also serve as chain gauges.

Safety factor.

For lifting chains, the safety factor 4 is required by law. This means that the manufacturer must prove that the breaking load of the lifting chains is at least four times its working load limit (WLL). Incidentally, since wire ropes and textile lifting means have a lower elongation under load and thus a lower energy absorption capacity than lifting chains, higher safety factors (5 or 7) apply to them.

WHAT IS THE ADVANTAGE OF A CHAIN SUSPENSION WHEN LIFTING?

Chain suspensions can be configured very flexibly according to the load to be lifted. The variety of available components and WLL is high, so that a large number of lifting tasks can be solved with one suspension. For example, the chain of a suspension can be easily and safely extended or shortened with special components. This allows the length of the chain strands to be adapted to the shape or weight distribution or centre of gravity of the load.

Attention: If you assemble suspensions yourself, you may only use lifting chains! Lashing chains are not permitted for lifting applications, as they have a different safety factor than lifting chains.

CONFIGURATION OF A CHAIN SUSPENSION:
WHAT QUESTIONS DO YOU NEED TO ANSWER FOR YOURSELF?

To select the individually suitable components for a chain suspension, you need answers to some important questions in advance. As soon as you know the answers, we recommend our digital suspension configurator at www.rud.com. Enter all required values here – and then you will receive a precise suspension recommendation.

1. What load (weight) should be transported or lifted with the chain suspension?

In order to select lifting chains and other suspension components with the correct WLL, you must know the weight of the load to be lifted. It is the first and most important value which you need for your suspension calculation.

 

2. How many strands should the suspension have?

Loads that are to be lifted using a chain suspension have already mounted lifting points or other attachment options sometimes. Their number depends on factors such as symmetry or asymmetry, centre of gravity and the shape of the load. As far as possible, all attachment options must be used for the lifting operation. Therefore, the number of strands of the used suspension results from their quantity. A suspension can have up to four strands. Attention: According to DGUV rule 100-500, the single strand WLL applies in the event of asymmetrical loading of a multiple strand suspension.

 

3. What usable length should the suspension have?

Depending on the height of the hall, the height of use and the size of the load, you need a certain usable length for your suspension. The permissible angle of inclination β of the suspension, which is indicated in this catalogue for each suspension, is also important. It must lie between 0° and 60° (calculated from the vertical). If the angle of inclination ß is more than 60°, you must increase the usable length of the suspension so that the angle is less than 60°.

 

4. What is the distance to the existing lifting points?

The distance between the lifting options used has an effect on the angle of inclination β of the suspension. This distance is therefore taken into account in the formula for calculating the optimum suspension.

Calculating the suspension correctly.

5. Where is the centre of gravity of the load?

Depending on whether the shape of the load to be lifted is symmetrical or asymmetrical, there are different requirements for the suspension you use. While, for example, a symmetrical load can possibly be lifted with a 1-strand suspension, a suspension with lifting chains of different lengths is usually necessary or at least recommended for an asymmetrical load.

 

6. Do you want to use an endless chain?

An endless chain can be used, for example, if the load does not have lifting points – in other words, if you have to create lifting points yourself. If you use an endless chain with choke hitch, the WLL of the suspension is reduced by 20 %; this has already been taken into account in the information on WLL in this catalogue. However, because of the greater effort involved, you should not use an endless chain if there are other slinging options. Attention: Do not use any lifting gear chains to wrap around loads!

7. What working environment will the suspension be used?

The type of working environment also has an influence over the right choice of suspension components. VIP-Components from RUD (grade 10) allow, for example, operating temperatures between –40 and 200 °C, for ICE-Products (grade 12) they are between –60 and 200 °C (in each case without WLL reduction). In harsh environments, ICE-Components are recommended because of the particularly wear-resistant material. At the same time, because of their lower weight compared to grade 8, ICE-Components offer clear advantages when the lightest possible handling is important.
