150 t all-electric offshore crane \u2014 the largest all-electric crane under contract. ZL200 at ratio 120, 2-stage, 1,400 kW PMSM at 4,800 rpm. The ZL200 replaced a 416W3 + dual hydraulic motor specification that was the baseline when the vessel was first designed. Weight saving: 1,100 kg at the crane head compared to the hydraulic baseline. The 368,000 Nm peak absorbed the classification proof-load test (187.5 t equivalent drum torque) with zero VFD faults. Commissioning time: 3 days (motor alignment + VFD parameterisation + brake test). The hydraulic crane commissioning on our previous vessel: 11 days. This crane has set the benchmark for every heavy-lift vessel crane our company will build for the next decade.<\/p>\n<\/div>\n

Main production winder at a 950-metre copper-gold mine, ZL200 at ratio 320, 3-stage, 1,100 kW AC motor at 4,200 rpm. The skip carries 24 tonnes; rope weight at full depth is 5,700 kg. Sustained drum torque during loaded hoist: 168,000 Nm \u2014 96% of ZL200 continuous. This is the deepest shaft we could serve with the ZL200 at this skip size \u2014 50 metres deeper and the torque would exceed the continuous rating. The 414W3 was the alternative at 140,000 Nm continuous \u2014 which would have been exceeded at this depth. The ZL200 provides the 35,000 Nm of additional continuous capacity that the 414W3 could not, plus regen recovery of USD 510,000 per year. The mine is currently the deepest production shaft operating on a ZL electric winch drive.<\/p>\n<\/div>\n

Dual-ZL200 configuration on an all-electric AHTS vessel \u2014 the first dual-ZL winch drive installation. Two ZL200 units at ratio 200, each driven by a 900 kW AC motor, torque-combined into a single drum at 350,000 Nm continuous capacity. The vessel completed its first ultra-deepwater anchor deployment at 2,000 metres \u2014 260 tonnes of chain handled by the dual-ZL200 with full regen during recovery. Energy saving versus the hydraulic twin-motor 419W3 equivalent: 38% per deployment cycle. The 4-star reflects the integration complexity: the torque-combining gearbox between the two ZL200 units added 350 kg and 200 mm of axial length to the winch assembly \u2014 dimensions that were not in the initial vessel stern layout. For future dual-ZL200 projects, publishing a combined unit dimensional envelope (both ZL200s + combiner) as a single assembly drawing would prevent the stern structure redesign we had to perform mid-build.<\/p>\n<\/div>\n<\/div>\n<\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"
One hundred and seventy-five thousand newton-metres. The absolute ceiling. The EP-ZL200 is the largest electric winch drive planetary gearbox that Korea Ever-Power manufactures \u2014 the final model in a ten-unit ZL series that spans from 27,000 Nm (ZL30) to this 175,000 Nm colossus. At 368,000 Nm peak, it exceeds the 419W3 hydraulic catalogue maximum by 12%. At 130 kW thermal power (1-stage), it provides the highest continuous power throughput of any ZL model without external cooling. At 5,000 rpm input with ratios from 4.4 to 4,504 across 1-5 stages, it covers every electric winch speed from near-direct-drive fast deployment to sub-centimetre-per-second precision positioning. There is nothing above it in the ZL family. Beyond 175,000 Nm electric, the catalogue transitions to the ZR right-angle series or to multi-unit ZL configurations.<\/div>","protected":false},"featured_media":990,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[969],"product_tag":[],"class_list":["post-988","product","type-product","status-publish","has-post-thumbnail","product_cat-winch-drive-planetary-gearbox","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/product\/988","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/comments?post=988"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/media\/990"}],"wp:attachment":[{"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/media?parent=988"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/product_brand?post=988"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/product_cat?post=988"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sr\/wp-json\/wp\/v2\/product_tag?post=988"}],"curies":[{"name":"\u0412\u041f","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
