General Notes
US Tower Corporation products are designed to meet specific design loads. To obtain optimal performance from the
products and achieve maximum allowable design loads, the products must be properly installed and used in
accordance with the installation and maintenance instructions and design limits provided by US Tower Corporation.
Proper product installation and maintenance requires careful attention to all notes, requirements, and instructions.
Failure to fully follow all of the notes, requirements, and instructions provided by US Tower Corporation may result in
improper installation of products. Improperly installed products may not perform to the specifications set forth and
may reduce a towers ability to resist the movement, stress, and loading that occurs from gravity loads as well as
environmental events such as earthquakes and high velocity winds.
US Tower Corporation does not guarantee the performance or safety of products that are modified, improperly
installed, improperly maintained, or not used in accordance with the specified design load limits.
All construction, installation, and maintenance activities shall be conducted in accordance with all Federal, State,
Local, OSHA, and other applicable laws, requirements, and ordinances.
The owner shall assume full responsibility and liability for the periodic inspection of the tower and accessory items
including the lift cables. Any cable (or other element) with any sign of distress or excessive stretch shall be
immediately inspected by qualified personnel and if necessary, replaced or repaired by qualified personnel.
US Tower Corporation reserves the right to change specifications, designs, and models without notice or liability for
such changes.
Do not modify a tower, any connection, or element of the tower. Modifications can result in an unsafe condition and
loss of the tower.
Do not overload a tower. Overloaded towers can result in an unsafe condition and loss of the tower. Refer to the
tower structural calculations for the design parameters and allowable design loading.

The towers in this manual have been designed for a Structure Class 1; Structures that due to height, use, or location
represent a low hazard to human life and damage to property in the event of failure and/or used for services that are
optional and/or where a delay in returning the services would be acceptable. Contact US Tower Corporation for other
Structure Classifications.
The towers in this manual have been designed for a Topographic Category 1; No abrupt changes in general

2. Safety Precautions
2.1 General Safety Precautions and Procedures
2.1.1 Never take short cuts
2.1.2 Never install a tower near power lines
2.1.3 Never work alone, always have at least one other person present
2.1.4 Never install a tower on a windy day, during a rain storm, or any time there is a likelihood of
lightening
2.1.5 Never climb the tower
2.1.6 Never raise or lower the tower when surfaces are iced
2.1.7 Never overload the tower by exceeding the antenna sail area or weight limit
2.1.8 Never reach into the center of the tower
2.1.9 Never try to catch the tower should it start to fall
2.1.10 Never use the raising fixture unless the tower is fully retracted
2.1.11 Never modify any parts of the tower or its accessories
2.1.12 Never get oil or grease on the manual winch brake disc fibers
2.1.13 Never rotate the antenna while raising or lowering your tower
2.1.14 Always check for underground gas lines, telephone lines, or other buried utilities
2.1.15 Always lower the tower to the fully retracted position if the wind is expected to exceed 50 MPH
2.1.16 Always use the proper tools and safety equipment
2.1.17 Always contact the power company if the tower, metal ladder, or any other objects come in
contact with power lines. Do not remove them yourself.
2.1.18 Always keep the tower and all components well maintained and inspected for wear or damage
that might lead to equipment failure or injury
2.2 Site Safety
2.2.1 The proximity of electrical lines to the installation site is extremely important. The nearest
electrical line should be at least two times the tower height from the tower center line.
2.2.2 Soil conditions that will allow for a good foundation and access to the tower under all weather
conditions. In many cases the information on soil types or best configuration is available from the
agency that will issue the building permit. Follow all OSHA, Local, and other safety requirements.
2.2.3 The tower should be located as close as is practical and safe to the related equipment.

3. Installation Instructions
3.1 Building the Foundation
The method of construction and safety is the responsibility of the Contractor / Installer. All work shall
be performed in accordance with all Building Code and Design Standard Requirements.
3.1.1 Refer to standard Foundation Notes and information in the Tower Calculations for foundation
requirements and design specifications.
3.1.2 Dig a hole to specifications of the Tower Calculations.
3.1.3 Build the rebar structure to the specifications of the Tower Calculations. See figure 1 for a
general reference diagram.

3.1.4 Build a wooden form for the concrete base as specified by the Tower Calculations. Place the
form over the hole and stabilize.
3.1.5 Install the Anchor Bolts in the T-Base as they will sit in the foundation. Tape the exposed
threads of the Anchor Bolts on the top side of the T-Base to protect them from concrete.
3.1.6 Suspend the T-Base with Anchor Bolts over the hole with stabilized 2x4’s assuring the hinged
side of the T-Base is perpendicular to the direction that the tower will be raised. Stabilize the bottom
of the anchor bolts to ensure they will remain vertically plumb during concrete placement. See figure 2.
