As is so often the case, two experts have three opinions, underpinned by well-founded half-knowledge. Unfortunately, this question also has to be based on physics, which is not everyone&#8217;s cup of tea.  <\/p>\n\n<p>The CTU code does not make things any easier because it ignores the question and does not provide a concrete answer. The occurring accelerations are precisely defined, which is an advantage for further considerations. <\/p>\n\n<p>First of all, you have to realize what is the essential difference between a truck and a ship. The truck moves on prefabricated roads that can be more or less good, but it will not, for example, leave the road because the road rotates around its longitudinal axis. The fact that this can be the case under certain circumstances can be seen in this video:  <\/p>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n <div class=\"brlbs-cmpnt-container brlbs-cmpnt-content-blocker brlbs-cmpnt-with-individual-styles\" data-borlabs-cookie-content-blocker-id=\"youtube-content-blocker\" data-borlabs-cookie-content=\"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\"><div class=\"brlbs-cmpnt-cb-preset-c brlbs-cmpnt-cb-youtube\"> <div class=\"brlbs-cmpnt-cb-thumbnail\" style=\"background-image: url('https:\/\/rothschenk.de\/wp-content\/uploads\/borlabs-cookie\/1\/yt_j-zczJXSxnw_hqdefault.jpg')\"><\/div> <div class=\"brlbs-cmpnt-cb-main\"> <div class=\"brlbs-cmpnt-cb-play-button\"><\/div> <div class=\"brlbs-cmpnt-cb-content\"> <p class=\"brlbs-cmpnt-cb-description\">You are currently viewing a placeholder content from <strong>YouTube<\/strong>.

It now has more distance to accelerate and absorb energy, which then affects the container wall with force.  <\/p>\n\n<div style=\"height:34px;width:0px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-4 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"762\" data-id=\"289569\" src=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1-1024x762.jpg\" alt=\"6-Slipping-load-in-container-shipment-red-legged-load-securing-1\" class=\"wp-image-289569\" srcset=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1-1024x762.jpg 1024w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1-300x223.jpg 300w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1-768x571.jpg 768w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1-600x446.jpg 600w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/6-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-1.jpg 1422w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"765\" data-id=\"289572\" src=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2-1024x765.jpg\" alt=\"7-Slipping-cargo-in-container-shipment-red-hand cargo-securing-2\" class=\"wp-image-289572\" srcset=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2-1024x765.jpg 1024w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2-300x224.jpg 300w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2-768x574.jpg 768w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2-600x448.jpg 600w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/7-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-2.jpg 1422w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" data-id=\"289575\" src=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3-1024x768.jpg\" alt=\"8-Slipping-cargo-in-container-shipment-red-hand cargo-securing-3\" class=\"wp-image-289575\" srcset=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3-1024x768.jpg 1024w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3-300x225.jpg 300w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3-768x576.jpg 768w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3-600x450.jpg 600w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/09\/8-Verrutschende-Ladung-im-Container-Schiffsversand-Rothschenk-Ladungssicherung-3.jpg 1422w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n<div style=\"height:57px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>In addition, there is the so-called angular acceleration.

The CTU code specifies a maximum load of 300 kg on an area of 60 x 30 cm. This corresponds to a pressure of 0.<sup>16kg\/cm2<\/sup>.    <br\/><br\/>A <a href=\"https:\/\/rothschenk.de\/en\/product-category\/dunnage-bags\/\">dunnage bag<\/a> may cause the ceiling to bulge and possibly become permanently deformed even at a low internal pressure. This can lead to the ceiling having to be repaired and the last user being left with the bill.   <br\/><br\/>However, depending on the extent of the curvature, it is also possible that the container stowed above it presses the curvature down with its own weight and transfers the force to the goods via the dunnage bag and damages them.<\/p>\n\n<p>Care must therefore be taken when using dunnage bags against the container ceiling.<\/p>\n\n<p>Form-fit securing, in which the load is stowed without gaps or the gaps are compensated for, is definitely the better method.<\/p>\n\n<p><strong>Yours, Sigurd Ehringer<\/strong><\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>&lt;&lt;  Previous Post<br\/><a href=\"https:\/\/rothschenk.de\/en\/episode-46-weight-distribution-according-to-ctu-code-5-or-10-or-60-40\/\">Episode 46: Weight distribution according to CTU Code 5% or 10% or 60\/40?<\/a><br\/><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-right\">To the next post  &gt;&gt;<br\/><\/p>\n<\/div>\n<\/div>\n\n<div class=\"wp-block-columns alignfull are-vertically-aligned-center has-background is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\" style=\"background-color:#516062\">\n<div class=\"wp-block-column blog_autor_zusatz is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:10vw\"><\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image aligncenter size-large is-resized is-style-rounded\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-1024x1024.jpg\" alt=\"\" class=\"wp-image-143199\" style=\"width:150px\" srcset=\"https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-1024x1024.jpg 1024w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-300x300.jpg 300w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-150x150.jpg 150w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-768x767.jpg 768w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-600x600.jpg 600w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater-100x100.jpg 100w, https:\/\/rothschenk.de\/wp-content\/uploads\/2024\/02\/sigurd-ehringer-ladungssicherung-ausbilder-und-berater.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-post-author\"><div class=\"wp-block-post-author__content\"><p class=\"wp-block-post-author__name\">Sigurd Ehringer<\/p><p class=\"wp-block-post-author__bio\">\u2714 VDI-zertifizierter Ausbilder f\u00fcr Ladungssicherung\r\n\u2714 Fachbuch-Autor\r\n\u2714 8 Jahre Projektmanager\r\n\u2714 12 Jahre bei der Bundeswehr (Kompaniechef)\r\n\u2714 20 Jahre Vertriebserfahrung\r\n\u2714 seit 1996 Berater\/Ausbilder in der Logistik\r\n\u2714 44 Jahre Ausbilder\/Trainer in verschiedenen Bereichen &#8212;&gt;\r\n\r\nIn einer Reihe von Fachbeitr\u00e4gen aus der Praxis, zu Themen rund um den Container und LKW, erhalten Sie Profiwissen aus erster Hand.
