Developed to enhance the trusted strength and reliability of ISC rigging pulleys, the 200 Series introduces significant structural improvements while maintaining dependable performance for demanding rigging operations.\u003c\/p\u003e\n\n\u003ch4\u003eRe-engineered forged aluminium frame\u003c\/h4\u003e\n\u003cp\u003eThe pulley plates have been redesigned using advanced stress analysis tools to reshape and redistribute material within the hot forged high-strength aluminium frames. This optimisation significantly improves performance under load. A unique axle and frame interlocking system, using heat-treated hardened stainless steel axles, reduces flex and deformation when subjected to extreme forces.\u003c\/p\u003e\n\n\u003ch4\u003ePatent pending SafeLock system\u003c\/h4\u003e\n\u003cp\u003eThe new SafeLock locking mechanism builds upon ISC’s well-known SpringLock system. It maintains quick and intuitive operation while achieving a low profile design, delivering secure and reliable locking performance suited to professional rigging tasks.\u003c\/p\u003e\n\n\u003ch4\u003eHigh strength for heavy-duty rigging\u003c\/h4\u003e\n\u003cp\u003eCompatible with ropes up to 16 mm (5\/8″), the pulley offers a minimum breaking strength of 250 kN and a working load limit of 50 kN. The anodised body is fitted with an orange pulley wheel, and each unit is individually serial numbered for traceability. Weighing 1887 g (4.1 lb), it is built to withstand the toughest rigging jobs.\u003c\/p\u003e\n\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible rope diameter up to 16 mm (5\/8″)\u003c\/li\u003e\n  \u003cli\u003eMinimum breaking strength 250 kN (56202 lbf)\u003c\/li\u003e\n  \u003cli\u003eWorking load limit 50 kN (11240 lbf)\u003c\/li\u003e\n  \u003cli\u003eHot forged high-strength aluminium construction\u003c\/li\u003e\n  \u003cli\u003eHeat-treated stainless steel axle\u003c\/li\u003e\n  \u003cli\u003ePatent pending SafeLock locking mechanism\u003c\/li\u003e\n  \u003cli\u003eAnodised finish with orange pulley wheel\u003c\/li\u003e\n  \u003cli\u003eWeight 1887 g (4.1 lb)\u003c\/li\u003e\n  \u003cli\u003eIndividually serial numbered\u003c\/li\u003e\n  \u003cli\u003eApproved to CE Machinery Directive 2006\/42\/EC and UKCA Supply of Machinery Regulations 2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISC","offers":[{"title":"Default","offer_id":52875235328343,"sku":"RP251A1","price":160.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/0785\/8263\/files\/ISC-16mm-Small-Rigging-Pulley-Block.jpg?v=1772085494","url":"https:\/\/treeworker.com\/products\/isc-16mm-small-rigging-pulley-block","provider":"www.treeworker.com","version":"1.0","type":"link"}
