FOR YEARS, BARE UNINSULATED, HIGH-VOLTAGE POWER DISTRIBUTION AND TRANSMISSION LINES HAVE CREATED A HAZARD TO USERS OF CRANES AND OTHER EQUIPMENT THAT CAN REACH AND TOUCH THEM. SUCH POWERLINES ARE NOT EASILY OBSERVED BY THE EQUIPMENT OPERATOR AND SUPPORTING WORKCREWS BECAUSE:

While contact with overhead high-voltage lines represents only 5% of the total electrical accidents, it is responsible for approximately 45% of the fatalities. MOST OF THESE ACCIDENTS COULD HAVE BEEN AVOIDED BY THE PROPER INSTALLATION AND USE OF A HIGH-VOLTAGE PROXIMITY WARNING SYSTEM. DURING THE PAST 25 YEARS, THERE HAS NEVER BEEN A SINGLE INJURY OR ACCIDENT INVOLVING EQUIPMENT EQUIPPED WITH A SIGALARM THAT IS INSTALLED AND ADJUSTED PROPERLY.

SIGALARM is a patented, solid state electronic safety system used for detecting the electrostatic field of any AC power line. It provides both audible and visual warning signals to alert the operator and attendant ground personnel when the boom comes within proximity of an energized high-voltage power line. A SIGALARM system is an “electronic eye” that serves as a backup operational aid.

1)As an automatic early warning system. Automatically Starts on Highest Sensitivity 2)As a proximity warning system Set alarm distance
