The orange bin sits on a blue A-frame, with two yellow hydraulic cylinders between frame and bin. A blue hydraulic power unit and a white control box stand at the side. The on-screen caption calls it a fixed tipping and discharge unit for metal chip carts.<\/p>\n<p>The bin starts tilted at its low point. The cylinders extend and the bin rotates up and over to its tipping position, then it rotates back down to rest. The test is run empty.<\/p>\n<h2 id=\"how-it-works\">How the box dumper works<\/h2>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>What happens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Load<\/td>\n<td>The bin rests at its low point, ready to be filled or set in place<\/td>\n<\/tr>\n<tr>\n<td>Tip<\/td>\n<td>The cylinders extend and the bin rotates over the pivot<\/td>\n<\/tr>\n<tr>\n<td>Discharge<\/td>\n<td>The load pours out over the bin lip<\/td>\n<\/tr>\n<tr>\n<td>Return<\/td>\n<td>The cylinders retract and the bin comes back down<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Two cylinders lift the bin evenly, so it does not twist on the pivot. The power unit beside the frame supplies the oil, and the control box starts and stops each move.<\/p>\n<h2 id=\"load\">Sizing the bin load<\/h2>\n<p>Illustrative example for a bin 1.0 m long, 0.8 m wide and 0.6 m deep:<\/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>Bin volume, 1.0 \u00d7 0.8 \u00d7 0.6<\/td>\n<td>0.48 m\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Bulk density of chips (illustrative)<\/td>\n<td>1,000 kg\/m\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Chip load, 0.48 \u00d7 1,000<\/td>\n<td>about 480 kg<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Chip bulk density changes a lot with the chip shape and the oil on it, so weigh a full bin of your own chips.

Keep people clear of the bin and the area it tips into while it moves.<\/p>\n<p>The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a box dumper<\/h2>\n<ul>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Bin size and its empty weight.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Material and its bulk density.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Height the load must pour into.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Bins per hour.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Fixed or mobile unit.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Power supply on site.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: What does this dumper tip?\nA: Bins of metal chips from machining, as in our test. Other bulk solids in bins can be tipped the same way.<\/p>\n<p>Q: How does it lift the bin?\nA: Two hydraulic cylinders rotate the bin over its pivot, fed from the power unit beside the frame.<\/p>\n<p>Q: How heavy is a full bin?\nA: Bin volume times bulk density, plus the bin. Our 0.48 m\u00b3 example holds about 480 kg of chips.<\/p>\n<p>Q: Is it fixed in place?\nA: Yes. This unit stands fixed, and the chip cart is brought to it.<\/p>\n<p>Q: How is it stopped?\nA: The red stop button on the control box stops it.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your box dumper in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with bin size and material to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the tipping height and load.<\/li>\n<li><strong>Book a site survey<\/strong> to check the site layout and power.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/tote-tipper-dumper\/\">Video: tote tipper dumper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-crate-and-tote-dumper\/\">Video: automatic crate and tote dumper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/pallet-inverter\/\">Pallet inverter<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Machine content: FHOPE engineering team, 2026-10-04<\/li>\n<li>Bin load example: our worked example, illustrative values<\/li>\n<li>Machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=JUyiuctxb_E\">our video on YouTube<\/a><\/li>\n<li>Standards scope: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010<\/a>, <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-04<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A box dumper tips a full bin so its load pours out without anyone lifting or shovelling it.
