As the chains run, the frame rolls from a tilt to lying flat.<\/p>\n<p>The turner is a crane accessory, not a floor machine; below it is weighed against our floor-mounted flipper.<\/p>\n<h2 id=\"chain-principle\">How a chain turner rolls a load<\/h2>\n<p>A chain turner hangs from the crane hook. Two endless chain loops pass under the load, and a motor drives them: one side rises, the other lowers, and the load rolls inside the slings.<\/p>\n<p>In practice:<\/p>\n<ul>\n<li><strong>The crane carries the full weight<\/strong> for the whole turn; the crane rating, not the turner, sets the limit.<\/li>\n<li><strong>The load turns about its own centre of gravity.<\/strong> Off-centre slings make the load swing towards the low side.<\/li>\n<li><strong>Any angle is possible<\/strong>, because the load is not clamped to a table \u2014 useful for welding positions.<\/li>\n<li><strong>No floor space<\/strong>: the turner moves with the crane.<\/li>\n<\/ul>\n<h2 id=\"floor-flipper\">Our equivalent solution: the floor-mounted 180\u00b0 flipper<\/h2>\n<p>For parts turned over many times a day, we build a floor-mounted flipper: the load sits on a table between two platens, and the machine turns it through 180\u00b0. The crane only places and removes the part.<\/p>\n<p>Values from our 180\u00b0 flipper range (FPMF, on our mould flipper page):<\/p>\n<table>\n<thead>\n<tr>\n<th>Model<\/th>\n<th>Max. loading<\/th>\n<th>Power<\/th>\n<th>Turning time<\/th>\n<th>Machine weight<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>FPMF-02<\/td>\n<td>2 t<\/td>\n<td>4.5 kW<\/td>\n<td>20\u201330 s<\/td>\n<td>2.0 t<\/td>\n<\/tr>\n<tr>\n<td>FPMF-05<\/td>\n<td>5 t<\/td>\n<td>5.5 kW<\/td>\n<td>20\u201330 s<\/td>\n<td>2.5 t<\/td>\n<\/tr>\n<tr>\n<td>FPMF-10<\/td>\n<td>10 t<\/td>\n<td>8.5 kW<\/td>\n<td>20\u201330 s<\/td>\n<td>3.0 t<\/td>\n<\/tr>\n<tr>\n<td>FPMF-20<\/td>\n<td>20 t<\/td>\n<td>10.5 kW<\/td>\n<td>20\u201330 s<\/td>\n<td>3.5 t<\/td>\n<\/tr>\n<tr>\n<td>FPMF-30<\/td>\n<td>30 t<\/td>\n<td>12.5 kW<\/td>\n<td>20\u201335 s<\/td>\n<td>4.0 t<\/td>\n<\/tr>\n<tr>\n<td>FPMF-40<\/td>\n<td>40 t<\/td>\n<td>16.5 kW<\/td>\n<td>20\u201335 s<\/td>\n<td>5.0 t<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For long frames, our mould flipper table range (FPFT) lists bed sizes [manufacturer rating], from FPFT-05 3010 \u00d7 1200 \u00d7 300 mm to FPFT-40 5560 \u00d7 2400 \u00d7 500 mm (L\u00d7W\u00d7H).<\/p>\n<p>Table and machine size are designed per load.

For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the emergency-stop arrangement.<\/p>\n<p>On a floor flipper the turning zone is fenced or marked, and the table only turns with the load clamped. With a crane-hung turner, everyone stays clear of the swing path for the whole turn.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: How does a chain turner differ from a floor-mounted flipper?\nA: The chain turner rolls the load in slings on the hook, and the crane carries the full weight. The floor flipper turns the load between two platens; the crane only places and removes the part. Our FPMF range covers 2\u201340 t.<\/p>\n<p>Q: How long does a 180\u00b0 turn take on a floor flipper?\nA: Our FPMF table lists 20\u201330 s up to 20 t and 20\u201335 s for the 30 t and 40 t models.<\/p>\n<p>Q: Can a floor flipper take a long frame?\nA: Yes. Table size is designed per load; we lengthen the table to support the frame along its length.<\/p>\n<p>Q: When is a chain turner the better choice?\nA: When turns are occasional, the crane has spare time, and parts vary widely in shape or need odd angles.<\/p>\n<p>Q: How does a floor flipper relieve a crane bottleneck?\nA: The crane only places the part and lifts it off again; a chain turner ties up the crane for the whole turn.<\/p>\n<p>Q: What decides the machine size?\nA: Weight, size and centre of gravity together \u2014 a bulky part can need a larger frame and motor than weight alone suggests.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>Sizing takes three steps:<\/p>\n<ol>\n<li><strong>Submit your part drawing<\/strong> with weight, centre of gravity and turns per shift, to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the flipper type, table size and turning time for your part.<\/li>\n<li><strong>Book a site survey<\/strong> to confirm crane access, floor space and loading direction.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/rotatable-180-degree-automatic-multipurpose-tilter\/\">180 Degree Load Inverter: Turning a Board Stack Over<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/mold-tipper-and-upender\/\">Industrial Mold Tipper and Upender: Heavy Mold Handling<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/the-roi-of-safety-why-90-degree-mold-upenders-are-replacing-overhead-cranes-in-industrial-toolrooms\/\">The ROI of Safety: 90-Degree Mold Upenders Instead of Crane Flipping<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/steel-sheet-180-degree-turning-and-upending-process\/\">Steel Sheet 180-Degree Turning and Upending Process<\/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\/mold-flipper\/\">Mold flipper<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Comparable machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=--qMrDfGJlI\">the video on YouTube<\/a><\/li>\n<li>FPMF range, loading, power, turning time, machine weight: <a href=\"https:\/\/www.fhopepack.com\/mold-flipper\/\">Mold flipper<\/a><\/li>\n<li>Mould flipper table bed sizes: <a href=\"https:\/\/www.fhopepack.com\/Hydraulic\/mold-flipper-table.html\">Mold flipper table<\/a><\/li>\n<li>Sheet stacks and C-type turnover: <a href=\"https:\/\/www.fhopepack.com\/Mechanical\/steel-sheet-upender.html\">Steel sheet upender<\/a><\/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> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A crane-hung chain turner rolls a long welded steel frame in mid-air.
