Anti-Theft Lighting Foundation image

Anti-Theft Lighting Foundation - CHANCE®

The CHANCE® Anti-Theft Lighting Foundation - or "AT Foundation" - is a device designed to stop thieves in their tracks, protecting both the public and private sectors from the high cost and intrinsic dangers of wire theft.

The AT Foundation concept is simple. The wires run through a clamping mechanism which prevents the wire from being pulled out of the ground through the baseplate.

The beauty of the device, for lighting contractors, is the fact that there's one less piece of hardware to order and one less piece to deal with logistically - the device is built right into the foundation. There are no separate parts to align when seting the pole and aligning the anchor bolts.

D.O.T. & Utility - Power-Installed Foundation Anchors image

D.O.T. & Utility - Power-Installed Foundation Anchors

Power-installed foundation anchors have been proved in thou- sands of installations throughout the world. CHANCE engineers have installed, tested and retrieved countless foundation anchors to confirm performance and durability. The amount of torsional force required to install a foundation anchor relates to its installed ultimate capacity. This means that holding strengths are predictable in most soils by choosing a foundation anchor based on soil data and by measuring torque during installation.

A typical Instant Foundation anchor can be installed in minutes using standard equipment. The superstructure can be mounted immediately - no waiting for concrete to cure. CHANCE foundation anchors can be installed in all weather conditions, thus eliminating weather related delays. They can function as permanent installations or serve as temporary foundations. They can be easily retrieved and reused.

The CHANCE Instant Foundation System includes a broad range of foundation anchors with various attachments for field adjustments. CHANCE support services include analysis of soil boring data, job-specific foundation anchor recommendations, personnel training videos and hands-on demonstrations.
Area Lighting image

Area Lighting

Parking, Area, and Site Lighting Foundations

Economical, No Site Preparation, Versatile

Be more profitable and meet your customers' concerns. Immediacy of low-cost installation delivers a total product with performance that builds your reputation.

Specifically designed for above-grade and on-grade mounting of parking-area/site lighting standards, these non-extendable foundation anchors have high-strength pipe shafts to resist bending moments and substantial installing-torque ratings. They often can be installed through macadam surfaces.

Airport Applications

Critical signal transmitters or receivers need stable foundations. The CHANCE INSTANT FOUNDATION® System screw anchors meet this criteria and are the preferred system by many organizations.

The FAA often uses this system on PAPI and NAVAID systems to place foundation systems deep in the soil below frost heave and expansive soil movements. The same is true for railroad signal boxes and emergency call boxes along highway systems. Simply positioning the foundation anchor and rotating it into the ground gives the structure a stable high performance foundation.

Economical, readily available, predictable and measurable capacity during installation are some of the advantages of the CHANCE INSTANT FOUNDATION® System. We have available information on applications, on wind generators, satellite receivers, solar panels, and other devices requiring stable foundations.

Helical Pile  image

Helical Pile - ROCK-IT'

The ROCK-IT' Lead Section is an innovative solution to penetrate rocky or high blow count soils without pre-drilling or field modification. The single carbide, patent pending design was developed after site testing of several rock anchor configurations to provide an economical, yet proven solution to reach load-bearing depths in high blow count material.
Square Shaft (SS) / Round Shaft (RS) Lead Sections image

Square Shaft (SS) / Round Shaft (RS) Lead Sections

The first section or lead section contains the helical plates. This lead section can consist of a single helix or up to four helices. Additional helices can be added, if required, with the use of helical extensions. Standard helix sizes are shown in the table to the right. The helices are arranged on the shaft such that their diameters increase as they get farther from the pilot point. The practical limit on the number of helices per anchor/pile is four to five if placed in a cohesive soil and six if placed in a cohesionless or granular soil.

Plain extensions are then added in standard lengths of 3, 5, 7 and 10 feet until the lead section penetrates into the bearing strata.
Square Shaft (SS) / Round Shaft (RS) Extensions image

Square Shaft (SS) / Round Shaft (RS) Extensions

Plain extensions , either square or round, are added in standard lengths of 3, 5, 7 and 10 feet until the lead section penetrates into the bearing strata.

Typically, square shaft extensions can be used in both compression and tension applications. Round shafts are more commonly used for compression and have a greater section modulus, resisting bending in weaker soils.
Combination (SS-RS) Helical Cast Transition image

Combination (SS-RS) Helical Cast Transition

The transition section adapts type Square Shaft (SS) helical lead sections to type Round.

Shaft (RS) extensions. The type RS-SS combination transition is used mainly in compression applications in areas where soft/loose soils are located above hard/ dense soils. The type RS material is less susceptible to buckling, provides greater lateral capacity, and greater moment capacity, than type SS material.

A square shaft lead will allow better penetration of the helices into hard/dense material than round shaft (RS). SS reduces the occurrence of "spin-out" (loss of thrust of helices).
Helical Pulldown Micropiles (HPM) image

Helical Pulldown Micropiles (HPM)

The Helical Pulldown Micropile (HPM) is used to form a grout column around the shaft of a standard helical anchor/pile. The installation process can employ grout only (see Uncased Helical Pulldown Micropile) or grout in combination with either steel or PVC casing (see Cased Helical Pulldown Micropile).

To begin the process, a helical anchor/pile is placed into the soil by applying torque to the shaft. The helical shape of the bearing plates creates a significant force that keeps the foundation advancing into the soil. After the Lead Section with the helical plates penetrates the soil, a Lead Displacement Plate and Extension are placed onto the shaft. Resuming torque on the assembly advances the helical plates and pulls the displacement plate downward, forcing soil outward to create a cylindrical void around the shaft. From a reservoir at the surface, a flowable grout immediately fills this void surrounding the shaft. Additional extensions and displacement plates are added until the helical bearing plates reach the minimum depth required or competent load-bearing soil. This displacement pile system does not require removing spoils from the site
