Cable tray seismic bracing is a support device that limits the displacement of electromechanical pipelines (such as water pipes, cable trays, and air ducts) and controls vibration during an earthquake, preventing pipelines from falling or being damaged. In regions prone to seismic activity, ensuring that your cable tray system is capable of withstanding such events is vital. While many occur in remote. THIS REPORT WAS PREPARED BY THE ORGANIZATION(S) NAMED BELOW AS AN ACCOUNT OF WORK SPONSORED OR COSPONSORED BY THE ELECTRIC POWER RESEARCH INSTITUTE, INC. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions. On some occasions the condui hanger rods 12 in or less in length be restrained. The 12 in length was determined based on the natural freq ncy of systems supported on the short hanger rods.
