Overview<\/h4>\r\n<p>\r\n\r\nHeavy machinery and construction equipment powerfully support our daily lives.\r\nThey perform powerful tasks that are difficult to accomplish by human power, such as road paving, construction, agriculture, forestry, and snow removal.\r\nThey are also used in times of disaster, contributing to lifesaving and quick restoration of life.\r\nHeavy machinery and construction equipment, which are indispensable for the safe development of towns and coexistence with nature, require high-quality wiring harnesses.\r\n<\/p>\r\n<\/div>\r\n\r\n<h4>2. About cables and wire harnesses for the heavy machinery and construction equipment industry<\/h4>\r\n<ul>\r\n<li>\u30fbWiring harnesses for heavy machinery and construction equipment are similar to those for automobiles. \r\nThere are main harnesses and sub-harnesses, and they are branched.<\/li>\r\n<li>\u30fbThe harnesses are required to have higher output than those of ordinary automobiles, and harnesses are needed to safely control the power.<\/li>\r\n\r\n<li>\u30fbIt is estimated that unmanned remote-controlled heavy machinery & construction equipment, which is expected to be introduced in the future, will require even more complex and higher quality cables.<\/li>\r\n<li>\u30fbThe main harness requires about 4,000 testing points, and the sub-harness requires about 200 points.<\/li>\r\n<li>\u30fbAs in the automotive industry, clamps and retainers are mounted on the cables.<\/li>\r\n<li>\u30fbIn the case of mass-produced products, testing is performed on a jig board with actual dimensions.<\/li>\r\n<li>\u30fbTesting is performed by approaching the target with a movable wagon-type tester.<\/li>\r\n\r\n<\/ul>\r\n<div class=\"c-spacer--s\">\r\n<h4>3.Cable & harness testing for the heavy machinery & construction equipment industry<\/h4>\r\n<ul>\r\n<li>\u30fbWiring and resistance testing are conducted.<\/li>\r\n<li>\u30fbIn many cases, resistors, diodes, and capacitors are mounted, which can be tested smoothly with customization of our testers.<\/li>\r\n\r\n<li>\u30fbElectrical testing is required to determine whether clamps and retainers are mounted or not by using fixtures.<\/li>\r\n<li>\u30fbHigh-voltage testing (withstand voltage\/insulation) is performed on cables that are exposed to harsh environments. Recently, demand for momentary disconnection testing is also increasing.<\/li>\r\n\r\n<li>\u30fbProgressive testing is also available in a customized version, in which the test is conducted while inserting the connector into the fixtures.<\/li>\r\n<li>\u30fbCAD information can be converted to prepare cable testing data.<\/li>\r\n<li>\u30fbIf portability is required, harness testers are stored in a wagon rack.<\/li>\r\n\r\n<\/ul>\r\n<\/div>\r\n\r\n\r\n\r\n\r\n","protected":false},"author":1,"featured_media":3136,"menu_order":19,"template":"","meta":[],"electrical-knowledge-cat":[127],"electrical-knowledge-tag":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3135"}],"collection":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge"}],"about":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/types\/electrical-knowledge"}],"author":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3135\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media\/3136"}],"wp:attachment":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media?parent=3135"}],"wp:term":[{"taxonomy":"electrical-knowledge-cat","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-cat?post=3135"},{"taxonomy":"electrical-knowledge-tag","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-tag?post=3135"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
