Container crane context: Gantry crane positioned at dock Overhead hoist mechanism: Winch + trolley system Spreader bar: Attachment point below hoist Function: Grips container corners, distributes load, tilts container for placement Spreader bar structure: Framework: Steel tubes\/beams forming rectangular frame Lifting points: 4 corner attachment rings (one per container corner) Electrical system: Motor-driven locks, position sensors, lighting Cables: Power supply for motors + control signals for locking mechanism Cable location (spreader bar): Vertical run (primary): From crane hoist (top) down 20\u201340 m to spreader bar (bottom) Function: Supply power for: &#8211; Corner lock solenoids (release container locks) &#8211; Position feedback sensors (confirm locks engaged) &#8211; Optional: Spreader bar lighting (visibility during operation) Simultaneous function: Act as partial mechanical support (share load with main hoist cable) Horizontal distribution (on spreader bar): From entry point distributed across spreader frame Supply all four corner lock motors Branching: May split into smaller branches (4\u00d7 circuits to corners) Mechanical load: Cable must withstand: Static tension: Weight of container payload (20\u201340 tons distributed) Dynamic loads: Jerking during load acceleration, swinging in wind Thermal: Tropical port environment, direct sun, saltwater spray Abrasion: Rubbing against spreader frame during operation Cable design philosophy: Dual function (unique): Electrical function: Deliver 300\/500V power for locking system Mechanical function: Share load-bearing (not primary structure, but support role) Different from: Pure electrical cables (festoon, lifting): Electrical function only Pure mechanical ropes: Mechanical function only BASKET SPREADER 730: Both functions integrated Speed specification rationale: 160 m\/min (relatively slow): Container crane cycle time: ~45\u201360 seconds per lift Descent distance: 20\u201340 m Descent speed: 20\u201340 m \u00f7 45\u201360 sec = 0.33\u20130.9 m\/s = 20\u201354 m\/min Average speed: ~30 m\/min (loading) + 20 m\/min (discharge) = 25 m\/min 160 m\/min specification: 6\u20138\u00d7 safety margin on speed Design: Allows for fast emergency ascent if needed Why not higher speed? Mechanical load constraint: Heavy cable (4000 N = ~400 kg equivalent) Inertia: Accelerating 400 kg + spreader bar + container inertia takes time Structural: Crane frame limits acceleration rates (safety interlocks) Result: 160 m\/min is practical maximum for loaded spreader bar","protected":false},"author":1,"featured_media":12113,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"left","csco_page_header_type":"title","csco_page_load_nextpost":"","footnotes":""},"categories":[8,464,1],"tags":[4491,56920,56851,56902,50541,58998,58994,58996,58991,58988,58997,58995,58993,58989,56850,58729,44912,58986,58248,38611,4490,44920,58992,53601,58981,8171,12879,2531,56862,43884,58990,58987,25858,2790,13124,58949,22893],"class_list":["post-12112","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cranes-and-material-handling-cable","category-flexible-cables-with-high-bending-life-and-fatigue-resistance","category-uncategorized","tag-feichun-cable","tag-40-to-90c","tag-10-kn-tensile-strength","tag-160-m-min","tag-300-500-v","tag-4000-n-tensile-strength","tag-6x6x2-5-mm","tag-6x6x3-3-mm","tag-7x6x2-5-mm","tag-7x6x3-3-mm","tag-8x6x2-5-mm","tag-8x6x3-3-mm","tag-9x6x2-5-mm","tag-9x6x3-3-mm","tag-aramide-yarn-central-unit","tag-awg-12","tag-awg-14","tag-basket-spreader-730","tag-class-5-2","tag-container-crane","tag-flame-retardant","tag-halogen-free-2","tag-load-bearing","tag-marine-grade-2","tag-mechanical-redundancy","tag-moisture-resistant","tag-ozone-resistant","tag-port-crane-cable","tag-sextuples-stranding","tag-short-lay-length","tag-special-csp-rubber-outer-sheath","tag-special-epr-insulation","tag-spreader-bar-cable","tag-tinned-copper-conductor","tag-uv-resistant","tag-vertical-suspension","tag-weather-resistant","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12112","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/comments?post=12112"}],"version-history":[{"count":2,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12112\/revisions"}],"predecessor-version":[{"id":12217,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12112\/revisions\/12217"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/12113"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=12112"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=12112"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=12112"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
