It is made of <strong>two extruded aluminium alloy profiles<\/strong>, joined in a single twin rail, on which the trolleys carrying the meat on hooks, gambrels, hangers or pendants run.<\/p>\r\n<p>The rail is anchored to the building structure with <strong>aluminium saddles<\/strong> with anchoring flanges and <strong>stainless steel screws<\/strong>, fixed into a special groove in the profile. Straight sections, curves and switches are combined to build the rail network that runs through the whole plant, from the slaughter line to the cold rooms and dispatch.<\/p>\r\n<img decoding=\"async\" class=\"aligncenter size-large wp-image-361521\" src=\"https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-768x644.png\" alt=\"Twin-track Birrail overhead rail installation by Bernad in a meat plant\" width=\"768\" height=\"644\" srcset=\"https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-200x168.png 200w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-400x335.png 400w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-450x377.png 450w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-500x419.png 500w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-600x503.png 600w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-700x587.png 700w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-768x644.png 768w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad-800x671.png 800w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2025\/04\/Carrileria-aerea-birrail-bernad.png 940w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\r\n\r\n<h2>Why can&#8217;t Birrail derail?<\/h2>\r\n<p>Birrail safety does not depend on how careful the operator is, but on the geometry of the system itself. These are the key design points:<\/p>\r\n<ul>\r\n<li><strong>Twin rail with a guided trolley.<\/strong> The trolley does not hang from a single flat bar: its nylon wheels and rollers run on the two parallel profiles of the rail, which keep it centred and guided along the whole route. By design, the trolley cannot slide off the track sideways.<\/li>\r\n<li><strong>Balanced load.<\/strong> The weight is shared between the two profiles and stays centred under the trolley. The carcass does not tend to tip or push the trolley to one side, even when it swings as it is pushed.<\/li>\r\n<li><strong>Curves and switches with continuous guidance.<\/strong> In curves, a set of inner and outer aluminium arches (350 mm radius) gives continuity to the track, and in switches a stainless steel direction needle steers the trolley onto the chosen track. The trolley stays guided exactly where the risk of leaving the track is highest.<\/li>\r\n<li><strong>End stops.<\/strong> Stainless steel end stops are fitted at the end of each section so that trolleys cannot run off the rail.<\/li>\r\n<li><strong>Anchoring sized to the load.<\/strong> The straight section has saddles approximately every 75 cm, and the spacing between saddles is adjusted to the load each installation has to carry. In tensile tests reproducing real working conditions, the Birrail system has performed far above the demands it faces in practice.<\/li>\r\n<\/ul>\r\n<p>The result is a system in which trolley, load and rail work together: <strong>the trolley cannot derail and the carcass cannot fall from the track because of a guidance failure<\/strong>, which is precisely the type of accident that worries cutting rooms most.<\/p>\r\n<img decoding=\"async\" class=\"aligncenter size-large wp-image-345737\" src=\"https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-839x1024.png\" alt=\"Exploded view of a Birrail overhead trolley with nylon wheels for the twin rail\" width=\"839\" height=\"1024\" srcset=\"https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-200x244.png 200w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-369x450.png 369w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-400x488.png 400w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-500x610.png 500w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-600x732.png 600w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-700x854.png 700w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-768x937.png 768w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-800x976.png 800w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-839x1024.png 839w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-1200x1464.png 1200w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-1259x1536.png 1259w, https:\/\/www.tiendabernad.com\/wp-content\/uploads\/2023\/03\/Carro-birrail-explosion-1678x2048.png 1678w\" sizes=\"(max-width: 839px) 100vw, 839px\" \/>\r\n\r\n<h2>Common risks of flat-bar and monorail systems<\/h2>\r\n<p>Flat-bar and monorail overhead systems are based on a single profile on which a roller or hook runs. They are simple, but their design concentrates the load on one support point and leaves the trolley less guided. In practice this can lead to:<\/p>\r\n<ul>\r\n<li><strong>The trolley or hook coming off<\/strong> when the load swings, is knocked or is pushed hard.<\/li>\r\n<li><strong>Derailment in curves, switches and rail joints<\/strong>, where the trolley changes direction and a single rail holds it less securely.<\/li>\r\n<li><strong>Falling loads<\/strong>, with a risk of impact and entrapment for staff working under or next to the track, as well as product loss.<\/li>\r\n<li><strong>Greater reliance on the operator<\/strong>, who has to guide the load more carefully to stop it swinging or coming off.<\/li>\r\n<\/ul>\r\n<p>From an occupational health and safety point of view, reducing the chance of a suspended load falling is one of the most effective measures in slaughterhouses and cutting rooms. The twin-track design acts directly on that risk.<\/p>\r\n\r\n<h2>Comparison: Birrail vs flat bar vs monorail<\/h2>\r\n<table>\r\n<thead>\r\n<tr><th>Criterion<\/th><th>Birrail (twin

id=\"faq-question-1\"><strong class=\"schema-faq-question\">What is Birrail overhead rail?<\/strong> <p class=\"schema-faq-answer\">It is a twin-track overhead conveying system for the meat industry: two parallel extruded aluminium profiles on which the trolleys carrying the hanging meat run.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-2\"><strong class=\"schema-faq-question\">Can a Birrail trolley derail?<\/strong> <p class=\"schema-faq-answer\">No. The trolley runs guided between the two profiles of the rail, also in curves and switches, so it cannot leave the track. At the end of each section, end stops prevent the trolley from running off.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-3\"><strong class=\"schema-faq-question\">What is the difference between Birrail and flat-bar or monorail systems?<\/strong> <p class=\"schema-faq-answer\">Flat-bar and monorail systems support the trolley on a single profile; Birrail guides it between two. This shares the load, stops the trolley coming off and reduces the risk of a carcass falling on an operator.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-4\"><strong class=\"schema-faq-question\">What is Bernad Birrail rail made of?<\/strong> <p class=\"schema-faq-answer\">The rail, arches and saddles are aluminium; the screws and direction needles are stainless steel, and the trolleys have nylon wheels.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-5\"><strong class=\"schema-faq-question\">How much load can a Birrail network carry?<\/strong> <p class=\"schema-faq-answer\">It depends on each installation: the network is calculated for the expected load by adjusting the spacing between saddles, which is about 75 cm on the standard section.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-6\"><strong class=\"schema-faq-question\">Can an existing Birrail installation be extended?<\/strong> <p class=\"schema-faq-answer\">Yes. The system is modular: rail sections, curves and switches can be added, or damaged sections replaced, without replacing the whole network.<\/p> <\/div> <\/div>\r\n\r\n\r\n<h2>Conclusion: safety starts with the design of the track<\/h2>\r\n<p>Choosing overhead rail is not just a question of capacity or price: it is deciding how much risk your staff take every time they push a carcass. With the twin-track Birrail system the trolley is always guided, the load travels balanced and derailment is removed as a cause of accidents.
