crane, <strong>crane span generally refers to the horizontal distance between the centerlines of the two runway rails<\/strong>. In simple terms, it determines how far the crane bridge can extend across the working area.<\/p>\n<p>For example, an overhead crane with a 20-meter span has an approximate 20-meter distance between the centerlines of its two runway rails. The crane travels longitudinally along the runway while the bridge moves across the workshop, allowing the hook to reach different lifting positions.<\/p>\n<p>It is important to understand that <strong>crane span is not the same as workshop width<\/strong>. Building columns, runway positions, equipment layout, and required clearances can all affect the final span. For a gantry crane, span generally refers to the distance between the two legs and is also determined by the required working area and site conditions.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"02_Why_Does_Crane_Span_Affect_Crane_Selection\"><\/span><strong><b>02 <\/b><\/strong><strong><b>Why Does Crane Span Affect Crane Selection?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The most direct function of crane span is to determine how much of the working area the crane can cover horizontally.<\/p>\n<p>If the span is too small, some lifting positions may be outside the crane&#8217;s working range. If it is significantly larger than necessary, it may increase the structural requirements of the bridge, legs, or building support system. Therefore, a larger span is not automatically better; it should match the actual working area.<\/p>\n<p>Span also needs to be considered together with <strong>lifting capacity, lifting height, duty class, and operating frequency<\/strong>. For example, two overhead cranes may both have a 10-ton lifting capacity, but if one has a 10-meter span and the other has a 25-meter span, their structural design requirements will not necessarily be the same.<\/p>\n<p>This is why crane selection is not only about how much weight the crane can lift, but also how large an area it needs to cover.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"03_How_Is_Crane_Span_Related_to_Building_Structure\"><\/span><strong><b>03 <\/b><\/strong><strong><b>How Is Crane Span Related to Building Structure?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-1137\" src=\"https:\/\/cranoxlifting.com\/wp-content\/uploads\/2026\/09\/\u5fae\u4fe1\u56fe\u7247_20260908173124_754_276.jpg\" alt=\"\u0418\u043b\u043b\u044e\u0441\u0442\u0440\u0430\u0446\u0438\u044f, \u0434\u0435\u043c\u043e\u043d\u0441\u0442\u0440\u0438\u0440\u0443\u044e\u0449\u0430\u044f, \u043a\u0430\u043a \u0438\u0437\u043c\u0435\u0440\u0438\u0442\u044c \u043f\u0440\u043e\u043b\u0435\u0442 \u043c\u043e\u0441\u0442\u043e\u0432\u043e\u0433\u043e \u043a\u0440\u0430\u043d\u0430 \u043c\u0435\u0436\u0434\u0443 \u0440\u0435\u043b\u044c\u0441\u0430\u043c\u0438 \u043f\u0443\u0442\u0438\" width=\"1944\" height=\"1094\" srcset=\"https:\/\/cranoxlifting.com\/wp-content\/uploads\/2026\/09\/\u5fae\u4fe1\u56fe\u7247_20260908173124_754_276.jpg 1944w, https:\/\/cranoxlifting.com\/wp-content\/uploads\/2026\/09\/\u5fae\u4fe1\u56fe\u7247_20260908173124_754_276-768x432.jpg 768w, https:\/\/cranoxlifting.com\/wp-content\/uploads\/2026\/09\/\u5fae\u4fe1\u56fe\u7247_20260908173124_754_276-1536x864.jpg 1536w, https:\/\/cranoxlifting.com\/wp-content\/uploads\/2026\/09\/\u5fae\u4fe1\u56fe\u7247_20260908173124_754_276-600x338.jpg 600w\" sizes=\"(max-width: 1944px) 100vw, 1944px\" \/><\/p>\n<p>For an overhead crane, the runway system normally relies on the building structure or dedicated supporting structures.
