Other Product
Input Speed Range：750-1500 r/min Input Speed Range：750-2500 r/min The GW Series Marine Gearbox, developed by Hangzhou Advance Gearbox Group Co., Ltd., is a compact and highly adaptable transmission system widely used in marine propulsion. Approved by major classification societies such as ABS, LR, and CCS, the gearbox series includes six models (GWC, GWD, GWS, GWH, GWL, GWK) tailored for various installation orientations and operational needs, including both reversing and reduction functionalities. Designed for rated input speeds of 400–1800 r/min and transmission ratios ranging from 2:1 to 6:1, these gearboxes ensure smooth, efficient operation and compatibility with most marine engines. On April 22nd, the “Junlan” — the world’s largest all-electric drive detachable eco-friendly suction dredger — was officially launched in the Guanting Reservoir Dredging Pilot Project in Beijing. This groundbreaking vessel, designed by CCCC Group, features core transmission components supplied by Advance Gears (Hangzhou Advance Gearbox Co., LTD). The vessel boasts a maximum dredging depth of 60 meters and a capacity to extract 2,000 cubic meters of sediment per hour, thanks to a state-of-the-art gear system integrated into its powerful mud pump and reamer systems. Engineered for precision and sustainability, “Joonlan” is capable of efficient, minimally invasive sediment removal, enhancing both water quality and ecological balance. With the integration of frequency-conversion driven excavation systems and zero-emission shore power modules, this vessel sets a new benchmark in green dredging technology. In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios. This technical article focuses on a high – power marine gearbox with PTO (Power Take – Off) and PTI (Power Take – In) functions. Traditional marine gearboxes have limitations, such as a lack of PTO and PTI functions, which can’t meet the diverse needs of ships. The new gearbox is composed of a hydraulically controlled clutch and gear transmission, working in conjunction with an adjustable pitch propeller. In PTO mode, the main engine drives the integrated motor for power generation, making use of residual power and enabling battery charging. In PTI mode, the shaft – driven generator gets power from the ship’s power grid for propulsion, enhancing ship maneuverability and achieving “zero” emissions. The gearbox is designed to overcome the drawbacks of traditional ones, offering advanced functions, low cost, high reliability, and high precision. It can reach six working states. The PTO and PTI clutches are arranged in series to realize different functions. With a reduction ratio range of 2:1 to 6:1 and a rated input transmission capacity of 3.448kw/rpm, it can withstand a propeller push – pull force of 450KN. This gearbox is suitable for multi – purpose work boats and ocean fishing vessels, leading the way in marine transmission with its high – efficiency, intelligent, and reliable mechatronic hybrid features. Converting a CUMMINS K19-M3 marine engine from a dry to a wet exhaust system requires modifications to both the exhaust and cooling systems. The exhaust pipe replacement is straightforward, but the cooling system adaptation is more complex, involving thermostat removal, rocker arm disassembly, and valve clearance adjustment. Technical expertise is crucial to ensure proper reassembly and engine performance. For parts lists or expert guidance, contact our engineering team at info@seamac.com.

The vessel boasts a maximum dredging depth of 60 meters and a capacity to extract 2,000 cubic meters of sediment per hour, thanks to a state-of-the-art gear system integrated into its powerful mud pump and reamer systems. Engineered for precision and sustainability, “Joonlan” is capable of efficient, minimally invasive sediment removal, enhancing both water quality and ecological balance. With the integration of frequency-conversion driven excavation systems and zero-emission shore power modules, this vessel sets a new benchmark in green dredging technology. In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios. This technical article focuses on a high – power marine gearbox with PTO (Power Take – Off) and PTI (Power Take – In) functions. Traditional marine gearboxes have limitations, such as a lack of PTO and PTI functions, which can’t meet the diverse needs of ships. The new gearbox is composed of a hydraulically controlled clutch and gear transmission, working in conjunction with an adjustable pitch propeller. In PTO mode, the main engine drives the integrated motor for power generation, making use of residual power and enabling battery charging. In PTI mode, the shaft – driven generator gets power from the ship’s power grid for propulsion, enhancing ship maneuverability and achieving “zero” emissions. The gearbox is designed to overcome the drawbacks of traditional ones, offering advanced functions, low cost, high reliability, and high precision. It can reach six working states. The PTO and PTI clutches are arranged in series to realize different functions. With a reduction ratio range of 2:1 to 6:1 and a rated input transmission capacity of 3.448kw/rpm, it can withstand a propeller push – pull force of 450KN. This gearbox is suitable for multi – purpose work boats and ocean fishing vessels, leading the way in marine transmission with its high – efficiency, intelligent, and reliable mechatronic hybrid features. Converting a CUMMINS K19-M3 marine engine from a dry to a wet exhaust system requires modifications to both the exhaust and cooling systems. The exhaust pipe replacement is straightforward, but the cooling system adaptation is more complex, involving thermostat removal, rocker arm disassembly, and valve clearance adjustment. Technical expertise is crucial to ensure proper reassembly and engine performance. For parts lists or expert guidance, contact our engineering team at info@seamac.com.

The GW Series Marine Gearbox, developed by Hangzhou Advance Gearbox Group Co., Ltd., is a compact and highly adaptable transmission system widely used in marine propulsion. Approved by major classification societies such as ABS, LR, and CCS, the gearbox series includes six models (GWC, GWD, GWS, GWH, GWL, GWK) tailored for various installation orientations and operational needs, including both reversing and reduction functionalities. Designed for rated input speeds of 400–1800 r/min and transmission ratios ranging from 2:1 to 6:1, these gearboxes ensure smooth, efficient operation and compatibility with most marine engines. On April 22nd, the “Junlan” — the world’s largest all-electric drive detachable eco-friendly suction dredger — was officially launched in the Guanting Reservoir Dredging Pilot Project in Beijing. This groundbreaking vessel, designed by CCCC Group, features core transmission components supplied by Advance Gears (Hangzhou Advance Gearbox Co., LTD). The vessel boasts a maximum dredging depth of 60 meters and a capacity to extract 2,000 cubic meters of sediment per hour, thanks to a state-of-the-art gear system integrated into its powerful mud pump and reamer systems. Engineered for precision and sustainability, “Joonlan” is capable of efficient, minimally invasive sediment removal, enhancing both water quality and ecological balance. With the integration of frequency-conversion driven excavation systems and zero-emission shore power modules, this vessel sets a new benchmark in green dredging technology. In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios. This technical article focuses on a high – power marine gearbox with PTO (Power Take – Off) and PTI (Power Take – In) functions. Traditional marine gearboxes have limitations, such as a lack of PTO and PTI functions, which can’t meet the diverse needs of ships. The new gearbox is composed of a hydraulically controlled clutch and gear transmission, working in conjunction with an adjustable pitch propeller. In PTO mode, the main engine drives the integrated motor for power generation, making use of residual power and enabling battery charging. In PTI mode, the shaft – driven generator gets power from the ship’s power grid for propulsion, enhancing ship maneuverability and achieving “zero” emissions. The gearbox is designed to overcome the drawbacks of traditional ones, offering advanced functions, low cost, high reliability, and high precision. It can reach six working states. The PTO and PTI clutches are arranged in series to realize different functions. With a reduction ratio range of 2:1 to 6:1 and a rated input transmission capacity of 3.448kw/rpm, it can withstand a propeller push – pull force of 450KN. This gearbox is suitable for multi – purpose work boats and ocean fishing vessels, leading the way in marine transmission with its high – efficiency, intelligent, and reliable mechatronic hybrid features. Converting a CUMMINS K19-M3 marine engine from a dry to a wet exhaust system requires modifications to both the exhaust and cooling systems. The exhaust pipe replacement is straightforward, but the cooling system adaptation is more complex, involving thermostat removal, rocker arm disassembly, and valve clearance adjustment. Technical expertise is crucial to ensure proper reassembly and engine performance. For parts lists or expert guidance, contact our engineering team at info@seamac.com.

New Breakthrough in China’s Wind Power Industry: Sliding Bearing Gearbox Localized
According to the relevant person in charge of the wind farm, compared with the traditional rolling bearing gearbox, the sliding bearing gearbox can reduce the power loss of about 20%-25%. This means that under the same input conditions, the power generation of a wind turbine can be increased by about 0.5%. A 3.3 MW onshore wind turbine, for example, can generate an additional 1,075,140 kWh of electricity over its entire lifecycle, which is equivalent to the annual electricity consumption of 360 households.
