Hubbell T/C Foundation

Hubbell T/C Foundation is an installing tool designed to aid in the installation of T/C anchors and extensions. It is intended for use by competent personnel familiar with and following good work and safety practices. The tool can be used to install T/C lead sections and extensions using steady down pressure to ensure minimum disturbance of the soil and maximum holding power. It can also be used to add extensions by bolting new sections to the foundation extension in the ground.

The T/C Foundation Installing Tool is equipped with a 7-5/8-inch dia. bolt circle and includes six 5/8-inch diameter grade 2 bolts for mounting a Chance Electronic Torque Indicator. The use of a Torque Indicator is recommended and should be mounted between the Kelly Bar Adapter and T/C Installing Tool.

These instructions do not claim to cover all details or variations in equipment, nor to provide for all possible conditions to be

! WARNING
Failure to monitor the condition of all parts and take corrective
action as necessary may lead to failure during use, resulting
in personal injury or property damage.
Check all output string bolts along the drive train periodi-
cally to ensure they remain tight. Loose bolts may fail at, or
below the anchor’s torque rating or contribute to damage
elsewhere in the output string. Check all parts periodically
for wear or damage and replace as necessary with original
equipment. Replacement bolts must be the same grade and
length as the originals.
These instructions are intended to illustrate the use of these installing tools. The T/C Foundation Installing Tool should be used by com-
petent personnel familiar with and following good work and safety practices. Should additional information and details be desired, or
if specific situations arise which are not covered adequately for the user’s purpose, the specifics should be referred to Chance. In some
cases, Chance may make specific recommendations concerning installation torque and installed depth limits for specific applications.
RECOMMENDED TIGHTENING TORQUES
BOLT DRY TORQUE (ft.-lb.)
1/2" - Gr. 5 75
5/8" - Gr. 2 95
Install T/C lead sections and extensions using steady down pressure to ensure minimum disturbance of the soil and maximum holding
power. Add extensions by bolting new sections to the foundation extension in the ground. Use the 3/4 inch bolts, nuts and lockwashers
provided with each extension. Attach T/C installing tool to the new extension section in the same manner as explained above. Continue
adding extensions until the desired torque or depth is achieved.
To install T/C Anchor lead section and extensions using the T/C
Installing Tool, raise the bails and hold the latches out while guiding
the tool onto the helix connector. Insert the pins into the holes in
the connector. Hook latches in under edge of the helix connector
in this position with the U-shaped bails.

! CAUTION
Heavy object can cause severe injury. Check anchor for cor-
rect position of hooks and balls so the anchor is locked in
place before moving.
The T/C Foundation Anchor Tool (C303-0594) is provided with
six 5/8-inch diameter grade 2 bolts to be used on a 7-5/8-inch dia.
bolt circle. These bolts are included to mount a Chance Electronic
Torque Indicator to the installing tool. When using a Chance Shear
Pin Torque Indicator, use the 1/2-inch dia. grade 5 bolts included
with the Indicator to mount it to the installing tool. The use of either
indicator is recommended. Mount the Indicator between the Kelly
Bar Adapter and T/C Installing Tool. When mounting these tools,
use the proper bolts, nuts, and lockwashers provided. The 5-1/4-inch
dia. bolt circle fits all standard Chance Kelly Bar Adapters with a
limited installing torque of 10,000 ft.-lb. The 7-5/8-inch dia. bolt
circle requires a special Kelly Bar Adapter which can be made or
ordered from Chance.
