From Helm to Rudder ...... Sperry Marine Steering Systems Do it All
- One Source for Heading Reference, Steering Controls and Electro-Hydraulic Steering Gear
- One Source for Installation Assistance
- One Source for Worldwide Service and Training
INTRODUCTION
Sperry Marine Steering Gear — features clevis-mounted hydraulic cylinders powered by the industrial grade steering power pumps. The system is a modular design which offers a great amount of flexibility to be installed in various ship configurations. In addition, the clevis design provides superior tolerances in installation alignments.
The double-acting hydraulic cylinders in the Sperry Marine system are offered in multiples of two or four dependent on required rudder torque. These cylinders are specially designed for the demands in marine applications.
The steering product offers ranges from simple hand hydraulic steering systems to complex electric-hydraulic power steering systems comprising motor starter systems, alarm systems, steering control systems, autopilot interfacing and rudder indicators.
All available modes of operation are available - full follow-up and non-follow-up in either single or dual configurations.
The Sperry Marine Steering System highlights are:
- Designed for straightforward and simple operation
- Modular in design for easy installation
- High quality components and vane pumps for long life and reliabilty
- Simplified maintenance
These key elements contribute to high levels of performance and safety.
Modular Design
Sperry Marine steering gears use standard set of cylinders that can be utilized in most applications. The only variable in design is the tiller, which is specified in concurrence with the vessel's characteristics and the required rudder deflections. By applying this method of modular design, each system can easily be designed and configured in accordance with specific requirements and applicable regulations, while obtaining the best cost-performance ratio. This process also ensures short delivery times once an order is placed. Based on the requiried rudder torque as derived from the modular mechanical design, the minimum requirements for the hydraulic power units are easily determined. Subsequently, the closed standard hydraulic power unit(s) is selected for the system.
Special Design
Special designed cylinders, however, remain possible at all times to accommodate specific customer requirements that cannot be met through the application of standard cylinders.
