ROHN Fold-Over Towers 55FK Series

Tower and foundation installations should be performed by qualified and experienced personnel using construction drawings. This document is to serve as a guide for sizing and buying the 55FK Fold-Over tower. All types of antenna installations should be thoroughly inspected by qualified personnel and re-marked with appropriate danger and anti-climb labels at least twice a year to ensure safety and proper performance.

 Wind Loading, Antenna Loading and Wind Survivability ratings vs. Height Documentation Provided by ROHN is available here as a Resource, but is by no means complete by itself or a susbstitution for Engineering Conducted Specific to your Application. Contact Us with any Questions you may have regarding Use prior to Purchase. All Information regarding the ROHN 55FK Tower line, Parts and Accessories is as accurate and complete as we can possibly provide given that this Resource Offering is subject to change without Notice and is beyond Our Control.



ROHN Complete Tower ID Nomenclature

Get all of the benefits of a Self-Supporting ROHN 55G tower, without ever having to climb!
With a ROHN 55FK, you can easily access the top mounted components, without ever having to climb the tower. In the time it takes to climb the tower, the top can be lowered down to ground level. Maintenance and replacements can be performed at a comfortable and safe working level in minutes, eliminating the need to work at dangerous heights. When the work is complete, the tower is easily returned to the upright position and locked into place. You never have to leave the ground.
ROHN's new design starts with a solid 45GSR base that is hinged at the top. ROHN 55G tower sections provide the mast, extending up to 60'. The design is based on 90mph winds, with no ice, and is available in heights from 20' up to 60'.

ROHN Tower series is the Workhorse of America's Large and Small Communications needs; from Governments, Institutions, Space Program, Olympics, TV AM FM Broadcast, Terrestrial Microwave to Business-Band Radio, HAM Radio Operators, to Off-Air Antenna TV and DTV Reception in Fringe areas outside the Surburban Broadcast Area. ROHN fabricates their towers from the highest quality steel. They maintain mill certification on the raw materials they receive to verify the material composition of each structural member. With a focus on quality, their fabrication facility has been awarded Certification by the American Institute of Steel Construction and the Canadian Welding Bureau. They have also been approved by the City of Los Angeles, CA and Clark County, NV as a certified fabricator. They are confident that their facility and staff can produce superior grade towers and poles that will meet your standards and weather the test of time. ROHN Towers, Accessories and their Construction/Assembly Assistance are also available via Call 877-660-0974 at anytime for assistance.



a) The intended purpose of these guidelines is to assist the customer and/or owner to retain the services of a Geotechnical Engineer.

b) It is not ROHN´s purpose or intent to supercede the Geotechnical Engineer´s knowledge, judgement and/or experience. It is the Geotechnical Engineer´s responsibility to add or delete from these items, based on local site conditions and other factors.

c) Additional information is provided in ANSI/TIA-222-G Annex G "Geotechnical Investigations".


a) ROHN will not accept any liability, either expressed or implied, for the use of, and omissions in, these guidelines.


a) Borings should be taken at tower legs for self-supporting towers and at the base and anchor points for guyed towers. For small self-supporting towers, two borings may suffice. For large self-supporting towers, one boring should be taken at each tower leg. A "small" self-supporting tower is assumed to have a face width less than 20 feet and a compression load less than 50 kips per leg. For pole structures, one boring may suffice.

b) The minimum boring depth should be 30 feet for pole structures, self-supporting towers and guyed tower bases. For guyed tower anchors, the minimum depth should be 15 feet. The actual depth of boring must be determined by the Geotechnical Engineer based on reactions, soil conditions and the type of foundation recommended.

c) If borings cannot be advanced to the desired depth, rock corings should be taken. Rock Quality Designation (RQD) values and compressive strengths should be determined.


a) The following properties, for each soil layer encountered, should be determined by field or laboratory testing and summarized in the geotechnical report:

1. Soil classification and elevations
2. Standard penetration values
3. Unconfined compression strength
4. Angle of internal friction
5. Cohesion
6. "In-Situ" soil density and moisture content
7. Rock quality designation (RQD) and percent rock sample recovered
8. Other properties unique to site conditions

b) The following items should be discussed in the geotechnical report:

1. Geological description of site
2. Observed and expected ground water conditions
3. Expected frost penetration depth
4. Corrosion potential of soil and corrosion protection recommendations
5. Site access and potential construction difficulties
6. Dewatering or site drainage requirements
7. Backfill material recommendations
8. Settlement considerations
9. Additional information to aid foundation designer
10. Recommended types of foundations
11. Design parameters for uplift, download and lateral load
12. Factor of safety considered when allowable vs. ultimate design parameters are provided
13. Recommended construction techniques and inspections
