The arm turns around the pallet, driven through an inverter, with a soft start and stop. While it turns, the film carriage travels up and down the mast. A photo eye finds the top of the load, and the PLC runs the bottom, middle and top winds, each set from 0 to 99.<\/p>\n<h2 id=\"arm-vs-turntable\">Rotary arm or

On a rotary arm machine the moving arm is the main hazard. The sweep area is closed by perimeter fencing with interlocked access doors, or by light curtains with muting where pallets enter and leave on a conveyor. The arm starts only when the area is closed, and an emergency stop is within reach. Guarding and CE documents are agreed per project.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: Why choose a rotary arm over a turntable?\nA: The load stays still, so tall, light or unstable loads are wrapped without moving them.<\/p>\n<p>Q: How fast does the arm turn?\nA: 15\u201318 r\/min on the R100, set by inverter.<\/p>\n<p>Q: What is the largest load?\nA: 1,200 \u00d7 1,200 \u00d7 2,000 mm on the R100; larger sizes are confirmed at quote.<\/p>\n<p>Q: Does it need compressed air?\nA: Yes, 6\u20138 kgf\/cm\u00b2, clean and dry.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Send your load size, weight and rate<\/strong> to info@fhopepack.com.<\/li>\n<li><strong>We check<\/strong> arm or turntable for your load.<\/li>\n<li><strong>We reply within 24 hours<\/strong> with a proposal and quotation.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Rotary-arm-wrapping-machine\/\">Rotary arm wrapping machines (product range)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Semi-auto-pallet-wrapping-machine\/Pallet-wrapping-machine-A200.html\">Semi-automatic pallet wrapping machine A200 (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/fhope-r100-rotary-arm-pallet-wrapper-with-film-cutter\/\">FHOPE R100 rotary arm pallet wrapper with film cutter<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/semiatuo-rotary-arm-pallet-stretch-wrapper\/\">Semi-automatic rotary arm pallet stretch wrapper<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>FHOPE quotation: R100 rotary arm pallet wrapper<\/li>\n<li>EN 415-6; ISO 12100:2010<\/li>\n<li>Our rotary arm pallet wrapper shown above<\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-19<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary A rotary arm pallet wrapper keeps the pallet still and turns the film around it on an arm.
