LASHING - RUD ICE Lashing Means

Important information!

Optimal load securing...

This also addresses those “casual transporters” who normally use their lorries for the transport of excavated earth or grit and are just sometimes driving with their low loaders or transport part loads on the lorry platform.

Just amongst those persons, an increased thoughtlessness and ignorance concerning the physical- and legal correlations can be found as compared with experts.

Dipl.-Wirt.-Ing (FH) Alexander Hoffmann Dipl.-Ing. (FH) Michael Betzler

To avoid sliding..

...best load securing – a compulsory legal necessity acc. EN 12195-1;2;3;4.

Every person responsible for low loaders, lorries or other transport vehicles, which has either sometimes or permanently to transport goods of any kind, should carefully read the following instructions because they help avoiding accidents, considerable costs and perhaps prosecution.

Hint for the EN 12195-1:2010:

The EN 12195-1: 2010 is contradictory to the results of many academic and by practical confirmed tests.

The status of a accepted technical regulation is doubtable.

To guarantee a sufficient safety level, the following statements refer to the EN 12195-1:2003 resp. to the VDI 2700 f

You should not wait until a accident has happened to think about a correct load securing. In many cases, the forces occurring during driving are underestimated and the strength of the lashing systems used is overestimated.

By using these pink-coloured lashing chains you will easier satisfy the critical eyes of the controlling authorities (avoids press charges).

The elastic elongation of the lashing chains with a permissible pulling force LC (half of the minimum breaking force) is only 1.1 up to 1.6 % compared with the new lashing belts < 7 %. This low elongation can be of big advantage when having long lashing means.

Concerning the afore-mentioned calculation example 2, at a minimum permissible pulling force LC of 9550 daN, a lashing chain 13 of grade 8 would be used. The standard version has a length of 3.5 metre, the chain link diameter is 13 mm. The permissible pulling force is 10,000 daN.

The example clearly shows the advantage of the ICE lashing chain generation. For a required permissible pulling force of 9550 daN, an ICE lashing chain of type ICE-VSK-10 would suffice

The length of the ICE standard version is 3.5 metre, too, however, the chain diameter is only 10 mm. The permissible pulling force LC amounts 10,000 daN, too. The weight of the standard chain of grade 8 is nearly 70 % higher than a grade ICE-120.

The table on pages 26/27 shows the improvements of the ICE quality compared with the EN standard. The clever calculators will recognise very quickly that the higher purchase prices will soon be compensated by the long-life and robust ICE chains with their easier handling.

The first calculation example has shown that for a safe vertical lashing (see page 4), the amount of the pre-tension force has to be known in all cases. This pre-tension force, however, is the big unknown. Furthermore, the driver is not able to recognise a decrease of the pre-tension force, caused by settling of the load during driving. This will result again and again in uncontrolled lashing forces questioning the effectiveness of the load securing. Referring to the calculation example 1 (see page 4) - vertical lashing- in theory 11 looped lashing belts should have been used at a required total pre-tension force Fv = 7698 daN and a STF of 500 daN.

With a loop, theoretically enabling a doubling of the pre-tension force, it cannot not be assured by 100 % that on the side opposite the ratchet there exists the same pre-tension force. By friction losses at the corners of the loop the pre-tension force can be considerably reduced. These losses may be reduced to a certain extent by edge protection devices; however, the safest way to absolutely avoid any losses is either the use of two tensioning elements (one element per side) or, as mentioned in the formula on page 4 at the bottom left, to increase the number of lashing means by factor 1.5.

Thanks to high pre-tension force STF RUD lashing chains are also ideal for vertical lashing!

RUD Ketten from Aalen, Baden Württemberg, launched as first chain manufacturer in 1994 the grade 10 under the name VIP-100 in an eye-catching pink powder coating.

This chain quality quite new at that time revolutionized the chain market, since it could be loaded by up to 30 % more, using the same nominal size

This resulted in a considerable saving of weight and improvement of ergonomics compared to grade 8 still widely common today.

13 years after the triumphal procession of grade VIP-100, RUD made the next innovation step in chain technology.

As world wide first manufacturer, RUD received approval for round steel link chains in grade 12 by the German BG to stamp “D”.

Compared with the common grade 8, this special quality class does have a breaking strength up to 60 % higher! For lashing technique this means a LC (Lashing Capacity = permissible lashing force) increase by up to 60 %.

Further technological features such as:

● Breaking elongation and ductility

● Deep temperature toughness

● Fatigue strength and wear resistance

could also be considerably be improved.

The enormous toughness with low temperatures of more than - 60°C finally inspired for the name of this chain generation: ICE120. The Colour was chosen in ICE-Pink (purple), thus guaranteeing a clear differentiation between the red of grade 8 and pink (magenta) of grade VIP-100, however, still maintaining the Pink Family of the RUD identification colour.

Ultra-light – up to 45 % reduction of weight!

ICE lashing chain replaces grade 8 of the next bigger nominal size

Due to the tremendous strength of the patented ICE material, a leap in the nominal size could be realised compared with grade 8; this means, for direct lashing, an ICE lashing chain, is able to replace a lashing chain of grade 8 of the next bigger nominal size.

The result: Up to 45 % reduction of weight!

The approved technical advantages of the VIP program were maintained with the ICE lashing chain and further developed. Tensioning-, connecting- and shortening elements were considerably improved in terms of weight and functionality. As a special highlight the tensioner ICECURT shows many advantages.

● exceeds the requirements of EN 12195-3,

● has a extra long adjustment way,

● has a patented preparation for theft protection via padlock (Type ABUS 85/40HB),

● is equipped with a RUD-ID-POINT® (refer to page 25),

● is easy to clean and lubricate,

● has a novel, convenient anti-loosening device,

● is easy and quick to handle – even with gloves,

● is extra light and robust – thanks to its innovative forging construction.

By using ICE lashing chains, the user has less weight to carry and lift, improved ergonomics, faster mounting possibilities and increased safety.

The ICE-STAR-HOOK in FEM weight-optimized design is up to 25 % lighter than a hook in grade 8 of the next bigger chain despite a big hook mouth width.

The magnetic sticking securing disc of the ICE-CURT prevents unintended loosening.

What will, however, be the use of the optimal calculation, the optimal lashing mean, if there suitable lifting- and lashing points at the load or on the vehicle have not been provided. Due to this fact, RUD has developed a complete range of high tensile lifting- and lashing points. As the photos show, well known vehicle manufacturers already have successfully used these helpful devices. These are forged, moveable eyes made of high-quality alloy steel.

These elements have also been tested and approved by the BG for vehicles and the TÜV Rheinland (German authority for technical supervision).

In particular to mention is the generation of lashing points with a clear LC indication in daN (see page 16-19). These extremely practical elements can additionally be fit at the vehicle by approved welders. Besides to the lashing points ready to weld with LC indication there is a comprehensive assortment of variants ready to bolt which can be used for load securing. All geometry data are available free of charge on www.rud.com for the own CAD design.

Earth moving machineries such as excavators, loaders, dozers and special machines for earth moving have to be equipped with lashing points for assuring a safe trans - port. Also for a safe lifting, clearly marked lifting points have to be provided. They have been prescribed in EN 474-1 (earth moving machineries - safety) since 1994 for all new machines.

Trucks, trailers and semi-trailers with stake bodies have already been equipped since a certain time with lashing points for applying lashing means for load securing. For realisation it is referred to EN 12640 “Lashing points on commercial vehicles for goods transportation”

Attention:

ISO 15818 has been in effect since March 2017. It is the first standard to define worldwide performance requirements for lifting and lashing points for earth-moving machinery. All RUD lifting and lashing points comply with this standard.

You certainly do not consider collecting tickets resulting from missing load securing. However, the risk considerably increases with increasing traffic checks. By using RUD products, you can protect yourselves and at the same time increase the safety for yourselves and others on roads.

It is not sufficient to secure containers only by vertical lashing, e.g. Y-lashing as shown on the right-hand photo. With the presence of ice, oil, mud or dirt there can be a low friction value of about u = 0.1 even by using friction increasing mats.

We recommend the following procedures

The only safe variant is the inclined lashing such as V-, X- or trapeze lashing with fix connection at the lashing point and the suspension pin.

Attention: The load can slip when looping the chain through the lashing point, as it can often be seen with a V-lashing in practical use.

This means, however, that a tensioner has to be provided at each lashing strand – you should accept the slightly longer tensioning time in favour of the safety! The flatter the vertical angle alpha, the higher container weights can be transported – or a thinner chain can be used

The right RUD Lashing Chain!

One of the biggest problems with securing of heavy loads is how to avoid a static over-determination. This means if more than two lashing means are used for each direction, only two of the lashing means used accept the complete or the biggest part of the force. More than two strands will bear in theory if all of these strands fulfil the following conditions:

same strand length
same lashing angles
same pre-tension
same lashing mean (-elongation)

The practitioner immediately recognizes that such a load securing cannot be realized. In order to solve this problem, you can draw on a trick: The lashing chains will be looped around and thus be lead in double strands from the load to the vehicle; the result will be four bearing strands in one direction.

Due to the loop, however, there must be a equation of the force in the double strands. This can for example be effected by a looping around a round lifting bitt, as shown in the two photos above. An even better equation of force can be obtained by VIP lashing chains with a balancer roll (see page 22).

Since with this “double lashing”, different angles and specific individual conditions have to be respected besides to the common lashing angles alpha and beta, this kind of load securing cannot be calculated in a common way.

Please let us have your specific task, we will find a solution!

A problem often occurring with direct lashing is the fact that no adequate lashing points are available at the load or the connection dimensions of the existing “lashing points” (often just holes) do not allow a correct attachment of the lashing hook.

Attention:

The safety latch of the lashing hook should be closed in hooked-in condition!
Lashing hook must only be loaded in the hook ground, never at the tip!

To adjust the lashing means to non adequate lashing points, the use of a shackle often causes problems since the shackles will be submitted to forbidden bending forces. An even better and especially flexible alternative is the endless chain (see adjacent photos).

A endless chain should be selected in the same nominal size and quality class as the lashing chain; thanks to the “doubling” of the chain, sharp edges at the endless chain will no longer represent a problem.

A special flexible endless chain can be generated by the ICE-Multi shortening claw (refer to page 22), by just connecting a piece of ICE- chain with the ICE-Multi shortening claw to a closed loop.

Special advantages:

The endless chain can be opened without tools and can be adjusted in its loop diameter.

Typical “direct lashing loads” without lashing points are stone blocks or concrete parts. By using a endless chain, a so-called “spring lashing” can be effected (adjacent photo).
