Heavy Duty Design
Kahlenberg is most widely known for designing extremely rugged and dependable work boat
propellers. The greatest single reason for the unsurpassed strength of Kahlenberg
Propellers is that they are designed to exceed industry standards with regard to blade
root and blade edge thickness. This provides for greater resistance to damage.
We utilize the latest propeller design software, and reference over 40 years of
accumulated vessel records kept in our database. By using both of these resources, we give
our customers the added security and confidence that their Kahlenberg Propellers are the
best available for their particular application. Especially when considering a propeller
for use in shallow or debris filled waters, know that propellers designed by Kahlenberg
will keep you in operation, not in dry dock.
Quality Manufacturing and Repair
Kahlenberg primarily manufactures and repairs three to five blade fixed pitch propellers
up to ten feet in diameter. We manufacture to our own designs as well as those supplied by
the customer, routinely following ISO R484 and ABS guidelines. Accurately machined
propeller hub bores are assured by blue-fitting with precision machined taper mandrels,
while accurate pitch is attained through the use of Kahlenberg designed and manufactured
pitchometers. Static balancing is standard practice, with dynamic balancing also being
available.
Most importantly for custom propeller manufacturing, we have maintained a solid base of
skilled craftsmen who take great pride in their work. These skilled technicians give us
the ability to manufacture or repair fixed pitch propellers for almost any requirement or
specification.
Proven Materials
The preferred material utilized in our manufacturing process is CF3 Low Carbon Stainless
Steel. When considering the overall benefits of this material in terms of strength,
corrosion resistance, and repairability, CF3 Low Carbon is the best material for inland
work boat use. Nickel Aluminum Bronze and Manganese Bronze are also available for open
water applications. For other industrial applications such as use in mixing vats,
Kahlenberg manufactures propellers of cast iron and steel.
Marine Shafting and Accessories
With substantial facilities for the manufacture of marine shafting, diameters from one
inch to fifteen inches can be accommodated. Rudder stocks and fairwaters are also machined
in house. In addition, several accessory items are kept in stock including Muff Couplings,
Stuffing Boxes, tailshaft nuts and keys.
The Complete Propulsion System
Consider the added security of having Kahlenberg manufacture and supply all of your fixed
pitch propulsion components. We will blue-fit and pre-assemble all components at our
facility prior to shipment, eliminating the possibility of improper fit, and reducing the
potential for unwanted vibration. |
