Guyed Towers are limited in Height due to the nature of Antenna and Ice loads versus the Cantilever Nature Of Wind against them, offset by the Downward force of all Downguy tensioned as specified, terminated to a properly embedded Anchor, the weight/size of the Foundation and the cohesive of the soil to prevent skid/pullout and all together to counter a Structural Failure or Tower tip-over moment, as well as the strength of the tower members to withstand these Forces against them. ROHN Tower Kits are designed based on assumptions made regarding Windspeed, EPA (Antenna Load), Ice Load, Transmission Cable Loads, Height, Standard Soil Conditions, Surrounding Environment and Duty (Exposure Categories).
The Pre-packaged Kits contain the parts called for based on this Stock Design. The Stock Design of these Kits does not account for the Variations of Historic Windspeed, Number of Antenna(e) Loading at Specific Height(s), Soil Engineering recommendations, Adjacent Structures, Communications Purpose, or Geo-Political Rules, Laws and Codes That will be Applicable to Your Project.
It is Recommended that you take the time to engage an local Engineer that has the expertise and available Information necessary to evaluate the Stock design for Applicability, and/or Fill Out the Tower Quote Data Sheet Form found by clicking the Specification Tab above and send to 3 Star Inc./ROHN for a review.
*Per Rev G requirements, any structure greater than 10' foot requires a climber safety device.
ROHN 55G Tower Sections & Concrete Embed Bases
Since there are various other Manufacturers of Towers and Tower accessories that copy the ROHN Tower design, if you are not sure of the manufacturer of your Tower, you can at least compare the actual measurements and design of yours to those found in the spec. sheets in the ROHN catalog section via the Link provided above to assure yourself that additional sections or parts will fit. We cannot make that determination for you as the ROHN clones are something we don't carry or otherwise represent in our Product line. All towers in the GT Series are constructed with high strength steel tubing and feature ROHN's exclusive Zig-Zag ® solid rod bracing to provide exceptional strength. All GT Series Towers are hot dip galvanized after fabrication. In this process, each section of the tower is totally immersed in molten zinc, allowing every square inch of the tower, inside and out, to be completely covered. Hot dip galvanizing protects all points of welding and construction against rust and corrosion while providing an attractive finish.
The 55G is a true multi-use structure that provides excellent strength for applications up to 400´. It´s offered with either heavy steel tube or solid steel rod legs to satisfy a wide variety of needs under varied conditions. When properly installed, the standard tower will support the loads shown on various guyed and self-supporting information sheets in the ROHN catalog.
Most Restrictions Allow for 50 feet of Height without the Necessity of Guy Wires, Anchors or Braces. However, No Tower is self supporting during construction! Always use temporary guys on the top most section, and install permanent guy wires as soon as a guy point height is reached. 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 substitution 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 55G 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.
