Abstract
A self-contained hydraulic thruster for vessel. A power pack is mounted on a forward end of a base, and a helm platform is mounted on an aft end of the base at a substantial height above the base. A reservoir in communication with the power pack is mounted on the helm platform, thus facilitating hydraulic fluid flow from the reservoir to the power pack, and also rendering the hydraulic system self-priming. At least one lower unit is tiltably mounted to the base aft end, laterally offset from the helm platform. Due to the lateral offset between the lower unit(s) and the helm platform, interference between the lower unit(s) and the helm platform is avoided when the lower unit(s) is retracted and tilted up for transportation, storage, or maintenance.
Claims14
A self-contained hydraulic thruster for vessel comprising:
- a helm platform mounted on a base at a substantial height thereabove;
- a power pack mounted on said base adjacent said helm platform, said base underlying said helm platform and said power pack, said base substantially co-extending with said helm platform and said power pack;
- and
- at least one lower unit tiltably attached to an aft end of said base, each said lower unit being mounted to said base laterally offset from said helm platform, whereby interference between said lower unit and said helm platform is avoided when said lower unit is retracted and tilted up.
A hydraulic thruster system, comprising:
- a helm platform mounted on a base;
- at least one lower unit attached at an aft of said base and laterally offset from said helm platform, said helm platform being mounted at a substantial height above said base;
- and
- a hydraulic power pack mounted on said base, and a hydraulic fluid reservoir in fluid communication with said power pack mounted on said helm platform, whereby when said lower unit is retracted and tilted up, said lower unit is disposed along a side of said helm platform.
A self-contained hydraulic thruster for vessel comprising a power pack mounted at a forward end of a base;
- a helm platform mounted at an aft end of said base at a substantial height above said base;
- a hydraulic fluid reservoir mounted on said helm platform, said hydraulic fluid reservoir communicating with said power pack;
- and at least one lower unit tiltably attached at said aft end of said base laterally offset from said helm platform, wherein when said lower unit is retracted and tilted up, interference between said lower unit and said helm platform is avoided.
