The biggest advantage of a double-girder crane is its ability to handle heavy loads efficiently, with high durability and operational stability. However, it comes with higher initial investment costs and requires more installation space.<\/p>\n<p style=\"text-align: justify;\">This type of crane is commonly used in large-scale factories such as metallurgy, steel manufacturing, industrial packaging, and thermal power plants.<\/p>\n<div id=\"attachment_5697\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-5697\" class=\"size-full wp-image-5697\" src=\"https:\/\/ktgindustrial.com\/wp-content\/uploads\/2025\/04\/Overhead-cranes-in-factories-2.jpg\" alt=\"Double-girder overhead crane\" width=\"800\" height=\"406\" srcset=\"https:\/\/ktgindustrial.com\/wp-content\/uploads\/2025\/04\/Overhead-cranes-in-factories-2.jpg 800w, https:\/\/ktgindustrial.com\/wp-content\/uploads\/2025\/04\/Overhead-cranes-in-factories-2-300x152.jpg 300w, https:\/\/ktgindustrial.com\/wp-content\/uploads\/2025\/04\/Overhead-cranes-in-factories-2-768x390.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><p id=\"caption-attachment-5697\" class=\"wp-caption-text\">Double-girder overhead crane<\/p><\/div>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"What_is_the_structure_of_an_overhead_crane_in_a_factory\"><\/span>What is the structure of an overhead crane in a factory?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol style=\"text-align: justify;\">\n<li>Main girder:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">The main girder is the primary load-bearing component of the overhead crane, typically designed as a box girder or using I-beam steel. It also serves as the track for the hoist or trolley to move along. When designing the main girder, it is essential to consider the lifting capacity and the <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/ktgindustrial.com\/new\/factory-span\/\" target=\"_blank\" rel=\"noopener\">span of the factory<\/a><\/span> to ensure structural rigidity, elasticity, and operational stability.<\/p>\n<ol style=\"text-align: justify;\" start=\"2\">\n<li>End girders (end trucks):<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">End girders are rectangular box-shaped steel structures, commonly 6 to 10 meters in length. Each end is equipped with a drive mechanism and rubber bumpers to reduce impact when the crane reaches travel limits. The end girders are connected to the main girder using bolts, flanges, or fillet welds depending on the design.<\/p>\n<ol style=\"text-align: justify;\" start=\"3\">\n<li>Wheels:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">Depending on the load and span, cranes use wheels of various diameters such as D200, D250, D300, D350, D400, D500, or axle-mounted wheels. These wheels ensure stable and smooth movement.<\/p>\n<ol style=\"text-align: justify;\" start=\"4\">\n<li>Lifting mechanism:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">The lifting system may include electric chain hoists, electric wire rope hoists, or trolleys. Chain and wire rope hoists are typically integrated with single-girder cranes, while trolleys are used in double-girder cranes for handling heavier loads.<\/p>\n<ol style=\"text-align: justify;\" start=\"5\">\n<li>Control system:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">Overhead cranes can be operated via different methods such as wired pendant control, wireless remote control, or integrated operator cabins\u2014depending on the operating conditions and work environment.<\/p>\n<ol style=\"text-align: justify;\" start=\"6\">\n<li>Crane runway (rails):<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">The crane operates on specialized steel rails, typically made from standard types such as P11, P15, P18, P24, P30, P38, or P43, selected based on load and system scale.<\/p>\n<ol style=\"text-align: justify;\" start=\"7\">\n<li>Bumpers (shock absorbers):<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">Bumpers are critical components designed to absorb impact when the hoist or crane reaches its travel limit. Made from engineered rubber, they offer high elasticity and excellent wear resistance. These components come in various sizes and shapes to suit a wide range of operational requirements.<\/p>\n<ol style=\"text-align: justify;\" start=\"8\">\n<li>Travel motors and drives:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">The travel system includes the motor housing, gear transmission, electromagnetic brakes, pinion gears, and brake diodes. The crane moves along the rails using four wheel assemblies\u2014each end truck includes one powered and one idle wheel. Motors typically use 3-phase, 380V \u2013 50Hz AC power.<\/p>\n<ol style=\"text-align: justify;\" start=\"9\">\n<li>Electrical system:<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">There are two main power supply systems: the transverse system for the hoist and the longitudinal system powering the entire crane.

This setup drives the wheels, which move the entire main girder of the crane along its designed travel path. Simultaneously, the trolley\u2014where the lifting mechanism is installed\u2014moves along a rail system mounted on the main girder.<\/p>\n<p style=\"text-align: justify;\">In certain situations, the braking system is activated to slow down or safely stop the crane\u2019s movement. The entire operation is controlled by a central control system, ensuring synchronized and precise coordination between all electrical and mechanical components of the crane.<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"What_factors_should_be_considered_when_installing_an_overhead_crane_in_a_factory\"><\/span>What factors should be considered when installing an overhead crane in a factory?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Unlike standard mechanical equipment, overhead cranes are used to lift and move heavy loads within factories. Therefore, the selection, design, and installation of cranes require a high level of technical accuracy to ensure safety, efficiency, and to avoid unnecessary costs. Below are key factors to consider when installing an overhead crane:<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Load_capacity\"><\/span>Load capacity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Maximum lifting capacity is a critical factor that determines the crane\u2019s technical configuration and overall cost. The greater the capacity, the more complex the structure and the higher the investment. It&#8217;s important to clearly define the actual weight of goods and frequency of use to select a crane with suitable power\u2014avoiding both underuse and overload risks.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Span\"><\/span>Span<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Span refers to the distance between the two parallel rails, corresponding to the crane\u2019s operational width. A larger span requires more robust steel structures and detailed technical planning, which can increase production and installation costs. Accurately determining the required span early on helps streamline cost estimates and system optimization.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Lifting_height\"><\/span>Lifting height<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Lifting height (also known as hook travel) influences the selection of the hoist and the required length of chain or wire rope. To ensure efficient operation, installers typically conduct an on-site survey, measuring parameters like column height and roof clearance to recommend the most suitable crane configuration.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Crane_runway_length\"><\/span>Crane runway length<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">This defines how far the crane will travel along the runway inside the facility. Runway length directly impacts the scale of rail installation, power supply system design, and overall project cost. Providing this specification early to the contractor enables faster and more accurate design and pricing.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Lifting_and_travel_speed_of_the_crane\"><\/span>Lifting and travel speed of the crane<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">The lifting and travel speed of an overhead crane is another important factor to consider. Each type of crane can be designed with one or multiple speed settings and may include an inverter (VFD) for flexible speed control based on operational needs.
