Description

DK 181005 B1 1 Opfindelsens anvendelsesomrade Den foreliggende opfindelse angår en sikkerhedstav der omfatter et stavelement med — indhak.DK 181005 B1 1 Field of application of the invention The present invention relates to a safety rod comprising a rod element with — notch.

Opfindelsen angår endvidere en fremgangsmåde til håndtering af tunge elementer samt anvendelse af en sikkerhedsstav.The invention also relates to a method for handling heavy elements and the use of a safety rod.

Teknikkens standpunkt I dag kendetegnes aflæsning af tunge emner (såsom beton elementer, beton bjælker — og lignende) ved, at en anhugger star på stige eller ovenpå emnet.The state of the art Today, the unloading of heavy objects (such as concrete elements, concrete beams - and the like) is characterized by a person standing on a ladder or on top of the object.

Anhugning fra stige medfører ergonomiske nedslidende arbejdsstillinger, grundet tung vægt i yderlige stillinger.Clinging from a ladder leads to ergonomically debilitating working positions, due to heavy weight in extreme positions.

Anhugning af emner, i mere end 2 meters højde, uden sikkerhedsforanstaltninger er typisk forbudt.Piling of objects, at a height of more than 2 meters, without safety measures is typically prohibited.

Der anvendes i dag ingen eller individuelt faldsikringsudstyr til sikring imod nedstyrtning, hvor brugen af faldsikring også medfører uønskede ergonomiske påvirkninger og besværliggør arbejdsprocessen.Today, no or individual fall protection equipment is used to protect against falls, where the use of fall protection also causes unwanted ergonomic effects and complicates the work process.

Selve anhugningen foregår i dag ved brug af løfteanordning som kæder, stropper eller wire, der er koblet til kran på arbejdspladsen.The piling itself today takes place using lifting devices such as chains, straps or wire, which are connected to a crane at the workplace.

Det valgte løfteanordning kobles til anhugningsgrej som krog, løftebeslag, øjebolt, sjækler eller ringkobling, som muliggør løft af emne, da det sættes omkring emnets løftanordning eller spændes om emnet.The selected lifting device is connected to attachment equipment such as a hook, lifting bracket, eyebolt, shackles or ring coupling, which enables the lifting of the workpiece, as it is placed around the workpiece's lifting device or tightened around the workpiece.

Anhugning af emnerne foregår i dag ude på arbejdspladserne i alt slags vind og vejr.Carving of the items takes place today outside at the workplaces in all kinds of wind and weather.

Dette gør at arbejdsforholdene for anhuggeren, stående på stige eller på emnerne, — besværliggøres og faren for nedstyrtning stiger.This makes the working conditions for the chipper, standing on a ladder or on the workpieces, — more difficult and the risk of falling increases.

Fra den amerikanske patentansøgning US 2015/0166308 Al er derfor kendt at lave nedfældede løfteanordninger i et betonelement således at elementerne kan stables oven på hinanden og således at anhugningsgrej kan forbindes til løfteanordningerne — på det øverste element i en stak beton elementer og derved løftes væk med en kran.From the American patent application US 2015/0166308 Al, it is therefore known to make recessed lifting devices in a concrete element so that the elements can be stacked on top of each other and so that attachment tools can be connected to the lifting devices — on the top element of a stack of concrete elements and thereby lifted away with a crane.

Men dette kræver stadig at anhuggeren er nød til at kravle rundt ovenpå elementerne.But this still requires the chipper to crawl around on top of the elements.

DK 181005 B1 2 Fra den internationale patentansøgning WO 03/021059 er det kendt at løfte betonelementer ved hjælp af en anordning, der kan fjern-afmonteres fra et løfteøje. Denne anordning er dog dyr og kompleks at bruge.DK 181005 B1 2 From the international patent application WO 03/021059 it is known to lift concrete elements by means of a device that can be remotely detached from a lifting eye. However, this device is expensive and complex to use.

Det er derfor et formål med opfindelsen at tilvejebringe teknik til håndtering af tunge elementer. Opfindelsen — Opfindelsen angår en sikkerhedstav der omfatter stavelement som inkluderer en første langsgående side og en anden langsgående side, hvor nævnte første langsgående side er modstående nævnte anden langsgående side, hvor en tredje langsgående side og en fjerde langsgående side udstrækker sig langsgående imellem nævnte første langsgående side og nævnte anden langsgående side og hvor nævnte — tredje langsgående side er modstående nævnte fjerde langsgående side. Sikkerhedstaven omfatter også et eller flere indhak i nævnte første langsgående side af nævnte stavelement, hvor nævnte indhak udstrækker sige hele vejen gennem nævnte stavelement fra nævnte tredje langsgående side til nævnte fjerde langsgående side. Sikkerhedstaven er kendetegnet ved, at sikkerhedsstaven yderligere omfatter et — låseelement, der udstrækker sig hele vejen på tværs af nævnte indhak ved et hjørne mellem nævnte første langsgående side og nævnte tredje langsgående side af nævnte stavelement. Det er fordelagtigt at udforme sikkerhedsstaven med indhak da dette muliggør, at — sikkerhedsstaven kan placeres ovenpå løfteanordninger i et betonelement i en stabel af tunge elementer. Herved behøves løfteanordningerne ikke at være nedfældede i elementet og løfteanordningerne beskyttes samtidigt af sikkerhedsstaven. Endvidere skaber sikkerhedsstaven afstand mellem stablede elementer således at en løfteline kan formonteres på et elements løfteanordninger inden et næste element stables — ovenpå og disse lofteliner kan føres ud over elementets side, således at en kranline kan fastgøres til løftelinerne uden at en anhugger behøver at kravle rundt påIt is therefore an aim of the invention to provide technology for handling heavy elements. The invention — The invention relates to a safety bar comprising a bar element which includes a first longitudinal side and a second longitudinal side, wherein said first longitudinal side is opposite said second longitudinal side, wherein a third longitudinal side and a fourth longitudinal side extend longitudinally between said first longitudinal side side and said second longitudinal side and where said — third longitudinal side is opposite said fourth longitudinal side. The safety rod also comprises one or more notches in said first longitudinal side of said rod element, where said notch extends say all the way through said rod element from said third longitudinal side to said fourth longitudinal side. The safety rod is characterized in that the safety rod further comprises a — locking element that extends all the way across said notch at a corner between said first longitudinal side and said third longitudinal side of said rod element. It is advantageous to design the safety rod with notches as this enables the safety rod to be placed on top of lifting devices in a concrete element in a stack of heavy elements. In this way, the lifting devices do not need to be embedded in the element and the lifting devices are simultaneously protected by the safety rod. In addition, the safety bar creates distance between stacked elements so that a lifting line can be pre-assembled on the lifting devices of an element before a next element is stacked — on top and these overhead lines can be passed over the side of the element, so that a crane line can be attached to the lifting lines without a feller having to crawl around on

DK 181005 B1 3 elementet. Det er endvidere fordelagtigt at forsyne Sikkerhedstaven et låseelement der afgrænser den nederste ydre kant af indhakket da sikkerhedsstaven derved ikke kan flyttes så længe en løfteline er monteret på et elements løfteanordninger. Herved øges sikkerheden under brug af sikkerhedsstaven.DK 181005 B1 3 the element. It is also advantageous to provide the safety rod with a locking element that delimits the lower outer edge of the notch, as the safety rod cannot thereby be moved as long as a lifting line is mounted on an element's lifting devices. This increases safety when using the safety rod.

Med opfindelsen muliggøres derved en aflæsning-/anhugningsmetode, som er let og nem for anhuggeren, og ved hvilken arbejdet med at aflæsse emner fra ladvogn kan udføres på en sikkerhedsmæssig- og fuldt forsvarlig måde. Arbejde i højden og — derved nedstyrtningsfaren elimineres, da sikkerhedsstaven gør, at anhuggeren kan sta på jorden og anhugge elementerne. Sikkerhedsstavken afhjælper således en arbejdsmiljømæssig udfordring i bl.a. bygge- og anlægsbranchen. Det skal påpeges, at termen ”tunge elementer” i denne sammenhæng skal forstås som — enhver form for byggeelementer, maskinelementer, bjælker, spærkonstruktioner og andre store elementer der i det væsentlige er stabelbare og vejer så meget, at de må håndteres med en kran. Det skal påpeges, at termen ”løfteline” i denne sammenhæng skal forstås som enhver form for wire, kabel, kæde, rem eller andet der kan bruges til løft af tunge elementer. Et aspekt af opfindelsen er, at nævnte stavelement omfatter et først indhak placeret i en første indhaksafstand fra en første ende af nævnte stavelement og et anden indhak placeret i en anden indhaksafstand fra en anden ende af nævnte stavelement, og hvor nævnte første indhaksafstand i det væsentlige er lig med nævnte anden indhaksafstand. Ved at forme sikkerhedsstaven med to indhak muliggøres, at sikkerhedsstaven kan anvendes på elementer med fire løfteanordninger og ved placere indhakkene — symmetrisk kan samme sikkerhedsstav anvendes i begge sider af elementet.With the invention, an unloading/chopping method is thereby made possible which is light and easy for the chopper, and by which the work of unloading objects from a lorry can be carried out in a safe and fully responsible manner. Work at height and — thereby eliminating the risk of falling, as the safety rod allows the chipper to stand on the ground and chip the elements. The safety staff thus alleviates a working environment challenge in e.g. the construction industry. It must be pointed out that the term "heavy elements" in this context must be understood as — any kind of building elements, machine elements, beams, rafter structures and other large elements that are essentially stackable and weigh so much that they must be handled with a crane. It must be pointed out that the term "lifting line" in this context must be understood as any kind of wire, cable, chain, strap or anything else that can be used for lifting heavy elements. One aspect of the invention is that said rod element comprises a first notch located at a first notch distance from a first end of said rod element and a second notch located at a second notch distance from a second end of said rod element, and where said first notch distance essentially is equal to said second notch distance. By shaping the safety rod with two notches, it is possible that the safety rod can be used on elements with four lifting devices and by placing the notches — symmetrically, the same safety rod can be used on both sides of the element.

DK 181005 B1 4 Et aspekt af opfindelsen er, at nævnte låseelement er stift forbundet til nævnte stavelement. At forbinde låseelementet til stavelementet er fordelagtigt da dette muliggør, at — låseelementet og stavelementet kan laves i forskellige materialer. Et aspekt af opfindelsen er, at nævnte låseelement er en integreret del af nævnte stavelement.DK 181005 B1 4 One aspect of the invention is that said locking element is rigidly connected to said rod element. Connecting the locking element to the rod element is advantageous as this enables the locking element and the rod element to be made of different materials. One aspect of the invention is that said locking element is an integral part of said rod element.

At forme låseelement som en integreret del af stavelementet er fordelagtigt da det muliggør en simpel fremstillingsproces.Forming the locking element as an integral part of the rod element is advantageous as it enables a simple manufacturing process.

Et aspekt af opfindelsen er, at nævnte stavelement er lavet af træ eller plast og hvor nævnte låseelement er lavet af fladjern.One aspect of the invention is that said rod element is made of wood or plastic and where said locking element is made of flat iron.

Det er fordelagtigt at lave stavelement af træ eller plast da disse materialer er billige og holdbare overfor tryk. Det er samtidigt fordelagtigt at lave låseelement er lavet af fladjern da det muliggør at låseelement kan designes så det hindrer anhugningen så lidt som muligt, samtidig med at det har tilstrækkelig styrke til at forhindre at det — knækker eller på anden vis beskadiges.It is advantageous to make rod elements from wood or plastic as these materials are cheap and durable against pressure. At the same time, it is advantageous that the locking element is made of flat iron, as it enables the locking element to be designed so that it hinders hooking as little as possible, while at the same time it has sufficient strength to prevent it from — breaking or being damaged in some other way.

Et aspekt af opfindelsen er, at nævnte sikkerhedsstav omfatter en eller flere visuelle elementer, der anviser en korrekt monteringsretning af nævnte sikkerhedstav.One aspect of the invention is that said safety rod comprises one or more visual elements that indicate a correct mounting direction of said safety rod.

Deter fordelagtigt at forsyne sikkerhedsstaven med visuelle elementer da dette muliggør at den korrekte orientering af sikkerhedsstaven nemt og sikkert kan kommunikeres til den person der monterer sikkerhedsstaven.It is advantageous to provide the safety rod with visual elements as this enables the correct orientation of the safety rod to be easily and safely communicated to the person who mounts the safety rod.

Det skal påpeges, at termen ” visuelle elementer” i denne sammenhæng skal forstås som enhver form for pile, piktogrammer, skriftlige anvisninger eller andet der kan anvise korrekt monteringsretning af en sikkerhedstav.It must be pointed out that the term "visual elements" in this context must be understood as any form of arrows, pictograms, written instructions or anything else that can indicate the correct mounting direction of a safety rod.

DK 181005 B1 Opfindelsen angår endvidere en fremgangsmåde til håndtering af tunge elementer der hver omfatter mindst en første løfteanordning og en anden løfteanordning forankret i hvert af nævnte tunge elementer, hvor nævnte fremgangsmåde omfatter følgende 5 trin: e placerer en første sikkerhedsstav ifølge ethvert af de foranstående krav ovenpå et første tungt element således at nævnte første løfteanordning af nævnte første tunge element anordnes i denne sikkerhedsstavs indhak, e placerer en anden sikkerhedsstav ifølge ethvert af de foranstående krav ovenpå nævnte første tungt element således at nævnte anden løfteanordning af nævnte første tunge element anordnes i denne sikkerhedsstavs indhak, hvor den første langsgående side af nævnte første sikkerhedsstav og nævnte anden sikkerhedsstav vender mod hinanden og hvor den tredje langsgående side af nævnte første sikkerhedsstav og nævnte anden sikkerhedsstav ligger an mod nævnte først tunge element, e placerer et andet tungt element ovenpå nævnte første tunge element således at nævnte andet tunge element hviler på nævnte første sikkerhedsstav og nævnte anden sikkerhedsstav, e placerer en tredje sikkerhedsstav ifølge ethvert af de foranstående krav ovenpå nævnte anden tunge element således at nævnte første løfteanordning af nævnte tredje sikkerhedsstav anordnes i denne sikkerhedsstavs indhak, e placerer en fjerde sikkerhedsstav ifølge ethvert af de foranstående krav ovenpå nævnte anden tunge element således at nævnte anden løfteanordning af nævnte fjerde sikkerhedsstav anordnes i denne sikkerhedsstavs indhak, hvor den første langsgående side af nævnte tredje sikkerhedsstav og nævnte fjerde sikkerhedsstav vender mod hinanden og hvor den tredje langsgående side af nævnte tredje sikkerhedsstav og nævnte fjerde sikkerhedsstav ligger an mod nævnte anden tunge element.DK 181005 B1 The invention also relates to a method for handling heavy elements, each comprising at least a first lifting device and a second lifting device anchored in each of said heavy elements, where said method comprises the following 5 steps: e placing a first safety rod according to any of the preceding claim on top of a first heavy element so that said first lifting device of said first heavy element is arranged in the notch of this safety rod, e places a second safety rod according to any of the preceding claims on top of said first heavy element so that said second lifting device of said first heavy element is arranged in this safety rod's notch, where the first longitudinal side of said first safety rod and said second safety rod face each other and where the third longitudinal side of said first safety rod and said second safety rod abut against said first heavy element, e places a second heavy element on top å said first heavy element so that said second heavy element rests on said first safety rod and said second safety rod, e places a third safety rod according to any of the preceding claims on top of said second heavy element so that said first lifting device of said third safety rod is arranged in this safety rod notch, e places a fourth safety rod according to any of the preceding claims on top of said second heavy element so that said second lifting device of said fourth safety rod is arranged in this safety rod's notch, where the first longitudinal side of said third safety rod and said fourth safety rod face each other and where the third longitudinal side of said third safety rod and said fourth safety rod abut against said second heavy element.

Denne fremgangsmåde er fordelagtigt idet sikkerhedsstavene beskytter løfteanordningerne samtidigt med at der skaves afstand mellem de tunge elementer.This method is advantageous in that the safety bars protect the lifting devices at the same time as distance is created between the heavy elements.

DK 181005 B1 6 Et aspekt af opfindelsen er, at fremgangsmåden endvidere omfatter at forbinde en løfteline til hver af nævnte første løfteanordning og anden løfteanordning på nævnte første tunge element og forbinde en løfteline til hver af nævnte første løfteanordning — og anden løfteanordning på nævnte anden tunge element. Da sikkerhedsstavene skaber afstand mellem de stablede tunge elementer, så er det fordelagtigt at forbinde løfteliner til hver af løfteanordningerne da dette vil lette aflæsningsproceduren.DK 181005 B1 6 One aspect of the invention is that the method further comprises connecting a lifting line to each of said first lifting device and second lifting device on said first heavy element and connecting a lifting line to each of said first lifting device and second lifting device on said second tongue element. As the safety bars create distance between the stacked heavy elements, it is advantageous to connect lifting lines to each of the lifting devices as this will facilitate the unloading procedure.

Et aspekt af opfindelsen er, at fremgangsmåden endvidere omfatter at føre nævnte løfteliner forbundet til nævnte første tunge element ud over en side af nævnte første tunge element og samle disse med et løfteøje og føre nævnte løfteliner forbundet til nævnte anden tunge element ud over en side af nævnte anden tunge element og — ligeledes samle disse med et løfteøje. Ved at samle den frie ende af løftelinerne med et løfteøje og fører løfteøjet og en del af hver af løftelinerne ud over en side af hvert af de tunge elementer i en stak af tunge elementer, så muliggøres det, at løfteøjet kan forbindes til en kran uden af en anhugger behøver at kravle ovenpå elementstakken. Yderligere angår opfindelsen anvendelse af sikkerhedstave ifølge enhver af de tidligere beskrevne sikkerhedsstave som afstandsstykker mellem stablede tunge elementer.An aspect of the invention is that the method further comprises leading said lifting lines connected to said first heavy element beyond one side of said first heavy element and gathering these with a lifting eye and leading said lifting lines connected to said second heavy element beyond one side of said second heavy element and - also collect these with a lifting eye. By joining the free end of the lifting lines with a lifting eye and passing the lifting eye and part of each of the lifting lines over one side of each of the heavy elements in a stack of heavy elements, it is possible for the lifting eye to be connected to a crane without of a chopper need to crawl on top of the element stack. Furthermore, the invention relates to the use of safety bars according to any of the previously described safety bars as spacers between stacked heavy elements.

Herved muliggøres det, at løfteliner 21 kan formonteres på alle løfteanordningerne 13, 14, 23, 24 under stabling af de tunge elementer 12, 17, 18. Disse løfteliner 21 kan så samles i et løfteøje 22, der føres ud over siden på det respektive tunge element 12 således at en anhugger kan fastgøre en krankrog til dette løfteøje 22 på aflæsningsstedet uden at — denne anhugger behøver at kravle op på de tunge elementer 12, 17, 18. Sikkerhedsstavens 1 første funktion, er at fungere som afstands- eller beskyttelsesblok for elementerne og løfteanordninger samt anhugningsgrej under transport. Højden af sikkerhedsstaven 1 skal være tilpas høj, sådan at kæder og kroge — kan ligge imellem elementerne. Den anden funktion er at sikre, at løfteanordning og anhugningsgrej påsat hos producent, ikke kommer i uhensigtsmæssige positioner under transport eller løft. Dette sikres ved indhak 7 og låseelementer 8, som sikrer at løfteanordning bliver i rette position. Størrelse af indhakkene 7 afhænger af løfteanordningens størrelse. Den tredje funktion er at sikre, at der under løft af — elementet ikke opstår “los genstand i luften”. Dette sikres ved hjælp af låseelementetDK 181005 B1 9 In this embodiment, safety rods 1, 15, 16, 19, 20 are placed at the lifting devices 13, 14, 23, 24 at both ends of all the heavy elements 12, 17, 18 (as shown in figure 3), so that safety rods 1, 15, 16, 19, 20 function as — spacers between the stacked heavy elements 12, 17, 18. This enables lifting lines 21 to be pre-mounted on all the lifting devices 13, 14, 23, 24 during stacking of the heavy elements 12, 17, 18. These lifting lines 21 can then be assembled in a lifting eye 22, which is led over the side of the respective heavy element 12 so that a hooker can attach a crane hook to this lifting eye 22 at the unloading location without — this hooker need to climb onto the heavy elements 12, 17, 18. The first function of the safety rod 1 is to act as a distance or protection block for the elements and lifting devices as well as attachment equipment during transport. The height of the safety rod 1 must be sufficiently high, so that chains and hooks — can lie between the elements. The second function is to ensure that the lifting device and attachment equipment installed by the manufacturer do not get into inappropriate positions during transport or lifting. This is ensured by notches 7 and locking elements 8, which ensure that the lifting device remains in the correct position. The size of the notches 7 depends on the size of the lifting device. The third function is to ensure that during lifting of — the element no "loose object in the air" occurs. This is ensured by means of the locking element

8. Sikkerhedsstaven 1 sidder låst omkring løfteanordning 13, 14, 23, 24 og anhugningsgrej igennem transport og løft. Den fjerde funktion er, at sikre anhuggeren imod faren, ved at sikkerhedsstaven 1 er vendt forkert. Dette gøres med visuelle elementer 11 f.eks. i form af pile i selvlysende/stærke farver, der angiver — retningen for sikkerhedsstaven 1. Pilene er placeret på toppen og på begge sider. Standard for pileretning skal angives af branche. Sikkerhedsstaven 1 aftages ved afhugning af emne. Den nye anhugningsmetode starter ved, at producenten påsætter sikkerhedsstaven 1 under produktion af de tunge elementer 12. Herefter stables elementerne 12 og læsses på lad eller sættevogn. Lastbilen ankommer til arbejdspladsen med elementer8. The safety rod 1 is locked around the lifting device 13, 14, 23, 24 and attachment tool during transport and lifting. The fourth function is to secure the chopper against danger by the safety rod 1 being turned the wrong way. This is done with visual elements 11 e.g. in the form of arrows in luminous/bright colors indicating — the direction of the safety rod 1. The arrows are located on the top and on both sides. The standard for arrow direction must be specified by industry. The safety rod 1 is removed when cutting off the workpiece. The new stacking method starts with the manufacturer attaching the safety rod 1 during production of the heavy elements 12. The elements 12 are then stacked and loaded onto a flat bed or semi-trailer. The truck arrives at the job site with elements

DK 181005 B1 10 12, som skitseret på figur 4. Her ses sikkerhedsstaven 1 liggende ovenpå/imellem elementerne 12, fastlåst i deres position. Løftelinerne 21 hænger ned langs siden af elementerne 12 og er samlet i en ring 22. Anhuggeren kan se pilene på sikkerhedsstaven 1, som sikrer at sikkerhedsstaven 1 er vendt korrekt. Anhuggeren — står på jorden og anhugger ringen 22 til kranen krog. Modtagere af elementerne 12 afhugger løfteanordning og anhugningsgrej efter placering på/i rette position. Sikkerhedsstaven kan spændes på anhugningsgrej og løfteanordning, og sendes ned til en evt. container eller lignende, sådan at løfteanordning og anhugningsgrej kan gå retur til producenten.DK 181005 B1 10 12, as outlined in figure 4. Here the safety rod 1 is seen lying on top of/between the elements 12, locked in their position. The lifting lines 21 hang down along the side of the elements 12 and are gathered in a ring 22. The cutter can see the arrows on the safety rod 1, which ensures that the safety rod 1 is turned correctly. The chipper — stands on the ground and chips the ring 22 to the crane hook. Recipients of the elements 12 cut off the lifting device and attachment tool after placement on/in the correct position. The safety rod can be clamped onto the attachment device and lifting device, and sent down to a possible container or similar, such that the lifting device and attachment gear can be returned to the manufacturer.

Sikkerhedsstaven 1 fungerer som en afstandsliste. Højden af sikkerhedsstaven 1 skal være tilpas højt, sådan at løfteanordning og kæder kan ligge mellem emnerne. Indhakkene 7 skal udformes i størrelse efter løfteanordning/anordning og har til formål at sikre den rette position under løft og kørsel af/med emnerne. Låseelementerne 8 har til formål at sikre, at sikkerhedsstaven ikke falder af under løft eller kørsel. Låseelementerne 8 kan også benyttes til spænde krogene omkring, til løft af sikkerhedsstaven, når elementerne 12 er afhugget og sikkerhedsstaven skal retur. Når sikkerhedsstaven er placeret korrekt, sørger låseelementerne 8 for, at sikkerhedsstaven er fastspændt imellem emne og kran. Pilene på sikkerhedsstaven 1 — angiver hvilken vej sikkerhedsstaven vender. Monteres den forkert, vil anhuggeren på pladsen, kunne se det og nægte løft. Er sikkerhedsstaven 1 vendt forkert, kan det være livsfarligt for anhuggeren. På figur 4 ses et eksempel på sikkerhedsstaven 1 i brug, ved ankomst til modtager. Anhugger vil kunne stå på jorden, og anhugge kæderne/ringene til kranens krog. Kæder m.m. er fastspændt under kørsel. I det foregående er opfindelsen beskrevet i forbindelse med konkrete udformninger af stavelementer 2, indhak 7, låseelementer 8 og andet, således som vist på — tegningerne, men det vil være klart for en fagmand, at opfindelsen kan varieres pa utallige måder inden for rammerne af de efterfølgende krav.The safety rod 1 functions as a distance list. The height of the safety rod 1 must be sufficiently high, so that the lifting device and chains can lie between the items. The notches 7 must be designed in size according to the lifting device/device and have the purpose of ensuring the correct position during lifting and driving of/with the items. The purpose of the locking elements 8 is to ensure that the safety rod does not fall off during lifting or driving. The locking elements 8 can also be used to fasten the hooks around, for lifting the safety rod, when the elements 12 have been cut off and the safety rod must be returned. When the safety rod is positioned correctly, the locking elements 8 ensure that the safety rod is clamped between the workpiece and the crane. The arrows on the safety rod 1 — indicate which way the safety rod faces. If it is mounted incorrectly, the feller on site will be able to see it and refuse to lift. If safety rod 1 is turned the wrong way, it can be fatal for the chopper. Figure 4 shows an example of the safety rod 1 in use, upon arrival at the recipient. Cutters will be able to stand on the ground and cut the chains/rings for the crane's hook. Chains etc. is fastened while driving. In the foregoing, the invention has been described in connection with specific designs of rod elements 2, notch 7, locking elements 8 and others, as shown in — the drawings, but it will be clear to a person skilled in the art that the invention can be varied in countless ways within the framework of the subsequent requirements.
