Pole Bearing Plate
The Pole Bearing Plate, also referred to as a bearing anchor plate or pole base plate, is a critical component in pole-line hardware. Designed to provide a firm footing for poles, it significantly enhances stability by distributing the load across a larger surface area. Manufactured from hot-dip galvanized steel per ASTM A153 standards, this product ensures durability and resistance to corrosion in challenging environments. Pole Bearing Plates are primarily used in utility and transmission applications to prevent poles from sinking into soft soils or being uplifted by external forces like water pressure or wind.
This product is available in various configurations, including standard models and custom sizes tailored to specific project requirements. Typically installed in pairs, Pole Bearing Plates are secured using bolts or lag screws, which must be ordered separately. They are compatible with wooden poles, H-frame structures, and direct-embedded steel poles. To use, place the plates at the base of the pole within the excavation site and fasten them securely to ensure optimal load distribution and stability.
Structurally, the Pole Bearing Plate features a robust design with integral spikes on its mounting surface to resist movement. Each plate is crafted from 3/8-inch thick steel per ASTM A36 specifications, ensuring high strength and reliability under heavy loads. This product is ideal for use in electrical transmission systems, utility poles, and other infrastructure projects requiring strong foundational support.

Frequently Asked Questions (FAQ)
What is the main purpose of a Pole Bearing Plate?
A Pole Bearing Plate is designed to provide a stable footing for poles, preventing sinking or uplift. It distributes the load over a larger surface area, enhancing the pole’s stability in soft soil conditions or areas prone to water pressure.
How many Pole Bearing Plates are needed per pole?
Typically, two Pole Bearing Plates are required per pole. They are installed in pairs to maximize load distribution and resistance to uplift. However, the exact number may vary depending on the specific application and structural requirements.
What materials are used to manufacture Pole Bearing Plates?
Pole Bearing Plates are made from 3/8-inch thick steel plates that meet ASTM A36 standards. They are hot-dip galvanized per ASTM A153 specifications, ensuring excellent corrosion resistance and durability in harsh environmental conditions.
How are Pole Bearing Plates installed?
Pole Bearing Plates are placed at the base of the pole within the excavation site. They are secured using 7/8-inch bolts or lag screws, which must be ordered separately. Proper tightening of bolts ensures optimal stability and load transfer.
Can Pole Bearing Plates be customized?
Yes, Pole Bearing Plates can be customized to meet specific project requirements. While standard sizes are available, custom dimensions can be ordered for unique applications or non-standard pole diameters.
