Discover the different classes of forks, including ITA hook-type forks, and other available models for your forklift.<\/p><p><strong>NOTE:<\/strong> <strong>ITA<\/strong> is a <strong>North American standard<\/strong> that defines how forks are mounted onto a forklift. An ITA fork (also known as a \u201chook-type\u201d fork) attaches easily to the forklift carriage without the need for bolts, simplifying installation, replacement, and ensuring compatibility with most forklift models. It is now the most widely used standard in industrial environments.<\/p><h2>3 Key Features of ITA Hook-Type Forks<\/h2><p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-16654\" src=\"https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60.png\" alt=\"\" width=\"800\" height=\"600\" srcset=\"https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60.png 800w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60-300x225.png 300w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60-768x576.png 768w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60-700x525.png 700w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/07\/unnamed-60-600x450.png 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p><p><a href=\"https:\/\/vallee.ca\/en\/forks\/ita-hook-type-fork\/\">ITA hook-type forks<\/a>, defined by the <a href=\"https:\/\/www.indtrk.org\/\">Industrial Truck Association<\/a>, are the most <strong>common fork types<\/strong> used in the material handling industry. Their clever design allows for <strong>interchangeability<\/strong> between forklifts, provided the carriage class is the same.<\/p><h3>1- What you should know about ITA hook-type forks:<\/h3><ul><li aria-level=\"1\">They are also called clip-on forks.<\/li><li aria-level=\"1\">Simplicity: Hooks at the top and bottom of the fork latch onto the bars of your forklift\u2019s carriage.<\/li><li aria-level=\"1\">Known for their <strong>durability, strength, and versatility<\/strong>, they are essential for transporting and stacking palletized goods in warehouses, distribution centers, and factories.<\/li><li aria-level=\"1\">They are compatible with a wide range of lifting vehicles, including small forklifts, high-capacity trucks, telehandlers, and even wheel loaders.<\/li><\/ul><h3>2- Thickness, Width, and Length: Dimensions of ITA Hook-Type Forks<\/h3><p>Fork dimensions are usually expressed in the order <strong>Thickness<\/strong> x <strong>Width<\/strong> x <strong>Length<\/strong>. A standard fork size, for example, is 1 \u00bd\u201d x 4\u2033 x 42\u2033.<\/p><h4><strong>Fork Thickness:<\/strong><\/h4><ul><li>Measured along the heel or the vertical part of the fork, also called the back or shank.<\/li><li aria-level=\"1\">The most common thickness is <strong>1 \u00bd inches<\/strong>, but other standard sizes include 1 \u00be\u201d, 2\u2033, and 2 \u00bd\u201d.<\/li><li aria-level=\"1\">The thickness depends directly on the <strong>forklift&#8217;s lifting capacity<\/strong> and the weight of the loads being lifted.<\/li><li aria-level=\"1\">To lift heavier weights with limited fork width, increasing the thickness may be required.<\/li><\/ul><h4><strong>Fork Width:<\/strong><\/h4><ul><li>Measured across the face of the blade or heel.<\/li><li aria-level=\"1\">Standard width for <strong>Class II forks is generally 4 inches<\/strong>.<\/li><li aria-level=\"1\">For Classes III and IV, typical widths are 5 and 6 inches, respectively.<\/li><li aria-level=\"1\">Some applications require wider or narrower forks; for example, telehandlers may use forks that are 4, 5, 6, or even 7 inches wide.<\/li><\/ul><h4><strong>Fork Length:<\/strong><\/h4><ul><li>Measured from the tip of the fork to the front face of the heel.<\/li><li aria-level=\"1\">A <strong>standard 42-inch <a href=\"https:\/\/vallee.ca\/en\/forklift-fork-dimensions-complete-guide\/\">fork length<\/a><\/strong> is common for Classes 2 and 3, as it fits standard-size pallets without extending beyond the rear.<\/li><li aria-level=\"1\">Forks should extend <strong>at least two-thirds the length<\/strong> of the load to ensure stability and <a href=\"https:\/\/www.ccohs.ca\/oshanswers\/safety_haz\/forklift\/fork_saf.html\">safety<\/a>. Forks that are too short or too long can damage the load, the equipment, or even injure personnel.<\/li><\/ul><h3>3- ITA Hook-Type Fork Classes<\/h3><p>Forks are categorized according to the <strong>ITA carriage class,<\/strong> which corresponds to a standardized height between the top and bottom bars of the forklift\u2019s carriage. There are<strong> 5 ITA carriage classes<\/strong>. Each class is associated with a <strong>maximum lifting capacity that<\/strong> both the forklift and forks can support. Your forks must match your forklift\u2019s rated capacity.<\/p><p><em>A forklift carriage example<\/em><\/p><p><img decoding=\"async\" class=\"alignnone size-full wp-image-16183\" src=\"https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2.jpg\" alt=\"\" width=\"800\" height=\"600\" srcset=\"https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2.jpg 800w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2-300x225.jpg 300w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2-768x576.jpg 768w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2-700x525.jpg 700w, https:\/\/vallee.ca\/wp-content\/uploads\/2025\/02\/V073600_2-600x450.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p><p><strong>ITA Classes and Their Capacities:<\/strong><\/p><ul><li aria-level=\"1\"><strong>Class 1:<\/strong> Carriage height 13 inches, Capacity &lt; 2,200 lb<\/li><li aria-level=\"1\"><strong>Class 2:<\/strong> Carriage height 16 inches, Capacity 2,200 to 5,500 lb<\/li><li aria-level=\"1\"><strong>Class 3:<\/strong> Carriage height 20 inches, Capacity 5,500 to 10,998 lb<\/li><li aria-level=\"1\"><strong>Class 4:<\/strong> Carriage height 25 inches, Capacity 11,000 to 17,600 lb<\/li><li aria-level=\"1\"><strong>Class 5:<\/strong> Carriage height 28.66 inches, Capacity 17,602 to 24,198 lb<\/li><\/ul><h3>Hook-Type Forks<\/h3><p>Although ITA forks are often referred to as hook-type forks, other <a href=\"https:\/\/vallee.ca\/en\/forks\/hook-type-fork\/\">generic hook-type fork<\/a> models differ in design.
