Extenda Life CrossarmWhat are Extenda-Life Crossarms?Download Extenda-Life PDF FileExtenda-Life Crossarms (Patented) are the culmination of several years of research and testing at Brooks Manufacturing Co. in an effort to extend the useable life of our products. Extenda-Life Crossarms are the same superior quality crossarms that Brooks has produced for decades, with the addition of a specially designed nail end plate hydraulically pressed into each end. These plates are not the same as "truss plates" with which most people in the industry are familiar. End plates are designed specifically for end grain application and have a special tooth design and pattern that locks itself in forming a permanent bond that prevents them from pulling out. Project History
Brooks Manufacturing Co. was asked by a major utility to find a way to eliminate premature failures of
Brooks developed a nail end plate that can be pressed into the end of the crossarms, and conducted several Why Use Extenda-Life Crossarms?The resulting cost savings to utilities goes far beyond the cost of the crossarm. Our research showed thatthe total cost to replace a crossarm varied between $1,000 and $8,000 depending on the equipment and personnel needed, the location of the structure, and the costs related to outages. This data showed that the cost savings involved with extending the life of crossarms is substantial. Extenda-Life Crossarms will last longer and perform better than standard crossarms. Some of the benefits include:
· Reduce catastrophic failures in the field under severe loading conditions. · Provide substantial long-term cost savings by extending the life of the crossarm and reducing expenditures for labor, equipment, and materials. · Eliminates the need for other anti-split devices such as anti-split bolts. · Allows for date tracking of crossarms. |
