(No tunnel, Control, Cable included)
The hydraulic motor is driven by a hydraulic pump. If a hydraulic pump and
associated tank are already installed on board, then , in most cases, this
assembly can be used for driving the bow thruster too. In addition to the
pump and the hydraulic stage tank, Vetus can supply the required load sensing
and control devices, as well as the high pressure hydraulic hoses, complete with
end fittings.
All these hydraulic bow thrusters may be fitted to fiberglass, steel or
aluminum tunnels or used as a stern thruster using the appropriate installation
kit
The three most powerful vetus bow thruster can also be driven in a safe
manner using a specially prepared diesel engine, instead of pump on the main
engine.
In this case, the matching hydraulic pump will be supplied as part of the
powerpack. Installing a powerpack on board can considerably reduce the
required generator set capacity, by operating hydraulic functions which are
normally electrically powered.
