Transverse Thrusters | Jastram – manoeuvring competence Products Product overview Low-Noise Thrusters Transverse Thrusters Rudder Propellers Drive and Control Systems Engineering Support Integrated Logistic Support (ILS) Low-Noise Thrusters Transverse Thrusters Rudder Propellers Applications Services About us Contact Language English Deutsch Fully tailored to your needs. Jastram has been developing and producing transverse thrusters since 1950. We specialise in fixed pitch propellers (FPP), which require minimal maintenance thanks to their robustness and durability. To improve performance, we continuously adapt the design of the propeller to the latest developments. Our thruster units meet your needs and requirements. With electric drive systems ranging from low-cost, three-step control to frequency-controlled drives for dynamic positioning, Jastram offers transverse thrusters for a wide range of vessel types. Thanks to reliable gears, worldwide service, direct contact to our service department and detailed specifications for each system supplied, we guarantee many years of disturbance-free operation. Optimal interaction between ship and systems. Our Jastram transverse thrusters are made from high-quality, certified materials and individually designed taking into account individual installation conditions. Class approvals for single components or for the entire transverse thruster are, of course, available. We offer vertical, horizontal or any other type of installation for electric, hydraulic or diesel engine drives. Our systems are optionally available with tunnel inlets individually adapted to the vessel’s contours. This optimises the efficiency and noise characteristics of the systems and simplifies installation at the shipyard. We can guarantee individual solutions for our customers that meet the highest demands. Benefits In detail Technical specifications Benefits 50 kW to 1,200 kW All key classifications Unrivalled durability of gears More than 4,000 thrusters in operation Efficient, quiet FP propellers In detail Safe down to the smallest detail. We strive to offer optimal technical comfort with our products. We develop safe, durable and, above all, efficient products that go together perfectly and in every possible way. A detailed view: The propeller is mounted with an oil pressure connection, allowing rapid assembly and disassembly when changing the shaft seal. The stainless steel ring at the propeller tip protects the tunnel from damage. A long service life is ensured through effective cathodic protection of the system, designed to last up to five years.
