Two people lifting a 6 m profile by hand is slow, tiring work, and edges get knocked in the process. A gantry stacker lifts each profile level along its full length and sets it down in the same place every time. Stacks come out square and with the right count.<\/p>\n<h2 id=\"machine\">How the gantry stacker works<\/h2>\n<p>The profiles here are long perforated metal profiles, fed in from the left on a blue roller line. A heavy blue gantry spans the line, with a row of lifting heads on vertical slides along its length. When a profile reaches its stop, the heads come down onto it, grip it and lift it clear. The gantry carries it sideways and sets it on the stack, then returns while the next profile feeds in.<\/p>\n<p>Because all the heads move together, the profile is held at several points and stays straight, even at 7 m. The main lift and the sideways travel each run on their own drive with adjustable speed. Fast moves cover the distance, and slow moves set the profile down gently.<\/p>\n<h2 id=\"specs\">Stacker data<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Item<\/th>\n<th style=\"text-align: left\">Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Profile length<\/td>\n<td style=\"text-align: left\">3,000\u20137,000 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Load per lift<\/td>\n<td style=\"text-align: left\">up to 250 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Single profile<\/td>\n<td style=\"text-align: left\">up to 100 kg<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Main lift speed<\/td>\n<td style=\"text-align: left\">0.1\u20130.512 m\/s<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Sideways travel speed<\/td>\n<td style=\"text-align: left\">0.026\u20130.256 m\/s<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Power<\/td>\n<td style=\"text-align: left\">380 V, 50 Hz<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Operators<\/td>\n<td style=\"text-align: left\">1<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"example\">Worked example: one pick cycle<\/h2>\n<p>Illustrative layout: the head drops 0.4 m to the profile, lifts 0.4 m, travels 1.2 m to the stack, drops 0.4 m, lifts 0.4 m and returns 1.2 m.

Light profiles can be lifted a layer at a time, up to 250 kg per lift, which multiplies the output. The 288 figure counts travel only. Real output is lower once speeding up, slowing down, gripping and the slow set-down are added, and we measure it at commissioning.<\/p>\n<h2 id=\"grip\">Choosing the gripper<\/h2>\n<p>We offer two main ways to pick profiles: mechanical clamp arms, and electromagnetic lifters. Magnets suit steel profiles and tubes, and on tube lines we use them for diameters from 6 to 95 mm. Aluminum is not magnetic, so aluminum profiles are picked with mechanical clamps. Vacuum cups need a closed surface to seal, so on perforated profiles like these we use clamps or magnets instead.<\/p>\n<h2 id=\"layout\">Where it fits in the line<\/h2>\n<p>The stacker sits after cutting or finishing, before strapping or wrapping. On aluminum lines we build stackers that also feed spacers and fill baskets, for example after sand blasting. Stacks then go on to bundle strapping or wrapping.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist<\/h2>\n<ol>\n<li>Profile shape, width, length and weight.<\/li>\n<li>Stack size and pattern.<\/li>\n<li>Profiles per hour.<\/li>\n<li>Spacers between layers, yes or no.<\/li>\n<li>Next step: strapping, wrapping or baskets.<\/li>\n<\/ol>\n<h2 id=\"safety\">Safety: EN 415-10 and ISO 12100<\/h2>\n<p>We design the stacker to EN 415-10 and assess its risks to ISO 12100. The main hazards are the moving gantry, the descending heads and a suspended load. The work area is fenced, and opening a guard door stops all motion.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: How long can the profiles be?\nA: From 3,000 to 7,000 mm.<\/p>\n<p>Q: What can it lift?\nA: Up to 250 kg per lift, and up to 100 kg for a single profile.<\/p>\n<p>Q: What limits the speed?\nA: Mostly the sideways travel distance to the stack, then grip and set-down time.<\/p>\n<p>Q: Can it pick steel and aluminum?\nA: Yes. Steel can be picked with magnets or clamps, and aluminum with clamps.<\/p>\n<p>Q: Which standard applies?\nA: EN 415-10 for the machine, and ISO 12100 for the risk assessment.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Send profile drawings, lengths and output<\/strong> to info@fhopepack.com.<\/li>\n<li><strong>We set<\/strong> the gantry, heads and stack layout.<\/li>\n<li><strong>We reply within 24 hours<\/strong> with a layout and quotation.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Aluminum\/aluminum-profile-stacker.html\">Automatic aluminum profile stacker (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Aluminum\/aluminum-stacking.html\">Aluminum profile stacking machine (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-profile-wrapping-machine-with-long-conveyor-buffer-system\/\">Automatic profile wrapping machine with long conveyor buffer system<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/steel-sheet-bundle-strap-packing-line\/\">Steel sheet bundle strap packing line<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/aluminum-profile-bundle-tying-machines\/\">Aluminum profile bundle tying machines<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>FHOPE product page: automatic aluminum profile stacker<\/li>\n<li>FHOPE project correspondence on stacking methods (mechanical arm and electromagnetic)<\/li>\n<li>Our profile stacking line shown above<\/li>\n<li>Worked example: illustrative layout<\/li>\n<li>Standards: EN 415-10; ISO 12100:2010<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-19<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A profile stacking line takes long metal profiles off the production conveyor one at a time and builds them into stacks for packing.
