The part sits in a black curved rocker cradle, the cradle rolls on its curved base, and the part ends up on its side, turned through 90 degrees, without slings or a crane flip. The footage was shared with us; our equivalent solution turns heavy plates, weldments and castings the same way, sized to your heaviest part.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"965\" height=\"551\" src=\"https:\/\/www.youtube.com\/embed\/q7iYKf7BQ7I\" title=\"How to Flip Heavy Steel Plates Safely: Automatic Plate Turnover Machine Guide\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<h2 id=\"table-of-contents\">Table of Contents<\/h2>\n<ul>\n<li><a href=\"#video\">What the clip shows<\/a><\/li>\n<li><a href=\"#why-cradle\">Why a roll-over cradle<\/a><\/li>\n<li><a href=\"#radius\">Cradle radius and footprint<\/a><\/li>\n<li><a href=\"#setup\">What we set per part<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist<\/a><\/li>\n<li><a href=\"#safety\">Safety<\/a><\/li>\n<li><a href=\"#engineering-faq\">Engineering FAQ<\/a><\/li>\n<li><a href=\"#next-step\">Next step<\/a><\/li>\n<li><a href=\"#related-reading\">Related reading<\/a><\/li>\n<li><a href=\"#sources\">Sources<\/a><\/li>\n<\/ul>\n<h2 id=\"video\">What the clip shows<\/h2>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>What you see<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Start<\/td>\n<td>A red weldment sits upright in a black curved rocker cradle<\/td>\n<\/tr>\n<tr>\n<td>Rolling<\/td>\n<td>The cradle rolls on its curved base<\/td>\n<\/tr>\n<tr>\n<td>Mid-turn<\/td>\n<td>The part leans over as the cradle keeps rolling<\/td>\n<\/tr>\n<tr>\n<td>End<\/td>\n<td>The part lies on its side, turned through 90 degrees<\/td>\n<\/tr>\n<tr>\n<td>Shop<\/td>\n<td>Pallets and parts around the cradle in the workshop<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"why-cradle\">Why a roll-over cradle<\/h2>\n<ul>\n<li><strong>Controlled turn.<\/strong> The part stays clamped in the cradle the whole way.<\/li>\n<li><strong>No crane flip.<\/strong> The crane only places and lifts the part.<\/li>\n<li><strong>Low floor load.<\/strong> The curved base spreads the load as it rolls.<\/li>\n<li><strong>Any shape.<\/strong> Fixtures in the cradle hold irregular weldments and castings.<\/li>\n<\/ul>\n<h2 id=\"radius\">Cradle radius and footprint<\/h2>\n<p><strong>Worked example (illustrative).<\/strong> A cradle rolling through 90 degrees travels a quarter of its circumference.<\/p>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Cradle radius (illustrative)<\/td>\n<td>1,500 mm<\/td>\n<\/tr>\n<tr>\n<td>Quarter circumference, 3.14 \u00d7 2 \u00d7 1,500 \u00f7 4<\/td>\n<td>about 2,360 mm<\/td>\n<\/tr>\n<tr>\n<td>Floor length for the roll, plus base (illustrative) 1,000 mm<\/td>\n<td>about 3,360 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"setup\">What we set per part<\/h2>\n<table>\n<thead>\n<tr>\n<th>Setting<\/th>\n<th>Depends on<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Cradle radius<\/td>\n<td>Part size and centre of gravity<\/td>\n<\/tr>\n<tr>\n<td>Capacity<\/td>\n<td>Heaviest part<\/td>\n<\/tr>\n<tr>\n<td>Fixtures<\/td>\n<td>Part shape<\/td>\n<\/tr>\n<tr>\n<td>Turn angle<\/td>\n<td>90 or 180 degrees<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"selection-checklist\">Selection checklist<\/h2>\n<ul>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Part size and weight.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Centre of gravity.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Turn angle: 90 or 180 degrees.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Floor space for the roll.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Fixtures for each part type.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Turns per shift.<\/li>\n<\/ul>\n<h2 id=\"safety\">Safety<\/h2>\n<ul>\n<li>Keep clear of the rolling path of the cradle.<\/li>\n<li>Clamp the part before the turn starts.<\/li>\n<li>Stop and lock the cradle before releasing the part.<\/li>\n<li>For CE markets, the machine is designed to ISO 12100 and EN 415-10.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: What does a roll-over cradle do?\nA: It turns a heavy part by rolling on its curved base, without a crane flip.<\/p>\n<p>Q: How much floor does it need?\nA: About a quarter of the cradle circumference plus the base; about 3,360 mm in the worked example.<\/p>\n<p>Q: Can it turn 180 degrees?\nA: Yes. A 180 degree turn needs a semi-circular base and more floor travel.<\/p>\n<p>Q: Is it only for plates?\nA: No, it also turns weldments and castings with fixtures, as in the clip.<\/p>\n<p>Q: Can you build this configuration?\nA: Yes. We build equivalent roll-over cradles sized to your parts.<\/p>\n<p>Q: Which standards apply?\nA: For CE markets, ISO 12100 and EN 415-10.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We match a roll-over cradle in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with part sizes, weights and centre of gravity, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong> with the machine data and layout.<\/li>\n<li><strong>Book a site survey<\/strong> so we confirm the floor space.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/why-relying-on-cranes-for-steel-sheet-flipping-is-costing-your-shop-money-and-safety\/\">Steel Sheet Flipper Instead of Crane Flipping<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/upender-with-custom-fixture-for-heavy-castings\/\">Upender with Custom Fixture for Heavy Castings<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/big-frame-flipper-for-180-degree-turning\/\">Big Frame Flipper for 180 Degree Turning<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Hydraulic\/Steel-Sheet-Flipper-and-Upender-machine.html\">Steel sheet flipper and upender machine<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine content: FHOPE engineering team, 2026-10-10<\/li>\n<li>Clip: <a href=\"https:\/\/www.youtube.com\/watch?v=q7iYKf7BQ7I\">the video on YouTube<\/a><\/li>\n<li>Cradle radius and footprint: our worked example, illustrative values<\/li>\n<li>Standards scope: ISO 12100:2010; <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<li>Proposal timing: approved house CTA (proposal within 48 hours)<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-10<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary This clip shows a roll-over cradle turning a heavy red machine weldment.
