Therefore, the company decided to take control and fit out a Skyline Barge 19 for its own use.<\/p>\n<p>The Skyline barges give a good working area. Square bowed, they are very functional and look very much like a floating section of quay measuring 60m LOA, with a 22m beam and a 3.5m draught.<\/p>\n<p>Since Ravestein specialises in producing heavy transfer gear such as linkspans, the company predictably wanted to design and fit out the whole unit as a completely bespoke, in-house package tailored to fit its own needs.<\/p>\n<p>This is where North Sea Winches stepped in. Ravestein ordered two hoist winches with a 14 ton capability, which take 286m of 32mm hoist wire each. The company also ordered a pair of 45 ton winches that can take 182m of 44mm wire rope. The crane when finished will have the capability of lifting 250 tons on a 14m outreach.<\/p>\n<p>However, the winches also have the job of pulling the frame of the crane itself up and down.<\/p>\n<p>This gives the barge flexibility, as the \u2018fold down\u2019 nature of the crane means that the whole thing can get under superstructure such as bridges with only a few metres above deck clearance. The crane tucks away neatly within the footprint of the barge, with nothing left to snare the unwary when the barge comes alongside.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>North Yorkshire UK based North Sea Winches is giving Ravestein a hand in making the Dutch company more effective.<\/p>\n","protected":false},"author":8,"featured_media":1854,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[8],"tags":[],"sponsor":[],"class_list":["post-1853","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-accessories-equipment"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/posts\/1853","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/comments?post=1853"}],"version-history":[{"count":1,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/posts\/1853\/revisions"}],"predecessor-version":[{"id":1855,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/posts\/1853\/revisions\/1855"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/media\/1854"}],"wp:attachment":[{"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/media?parent=1853"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/categories?post=1853"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/tags?post=1853"},{"taxonomy":"sponsor","embeddable":true,"href":"https:\/\/www.maritimejournal.com\/get-set-for-workboat-2050\/wp-json\/wp\/v2\/sponsor?post=1853"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
