Electric vehicle barriers provide speed and reliability.

If you ‘ve seen a Hollywood spy/thriller flm in the by few yearse, you ‘ve undoubtedly witnessed a few fomite security barriers in natural process. These barriers promptly rise out of the land in the tied of an fire or security hazard, protecting buildings, installations or other sensible areas from speeding vehicles .
automatic Security Systems, Inc. ( RSSI ), a Panama City, Fla, manufacturer of fomite security barriers, has developed a simple and economical answer to physical access manipulate, the RSS-2000- an electric, eminent performance, solution for raising wedge-style barriers .
RSSI designed an alternative all electric fomite barrier that is childlike to install and operate, authentic, and cost-efficient to maintain. One advantage of using electrick barriers over hydraulics is environmental ; electric barriers have no worry about petroleum escape.

“ The chief difference between a hydraulic barrier and an electric barrier is performance. With electric motors, the barrier can operate faster-with more duty cycles and operations in a given time period-without sacrificing dependability, ” said Bill Jempty, VP of sales and selling for RSSI .
For a linear actuator that supported these goals, RSSI turned o Exlar Corp, based in Chanhasen, Minn. While RSSI had previously worked with a different linear gesture products manufacturer, that company could not design a suitable solution within RSSI ‘s timeline
“ RSSI gave us the amphetamine and force criteria they desired, equally well as the amount of options that they wanted for the actuator. Once that standard was defined, we produced an actuator in one week and sent it to the customer for testing purposes, ” said Jason Eckman, regional sales coach for Exlar.

The actuator that made the hack, the GSX40, combines the advantages of roller srew technology with a brushless servo design. The roller screw mechanism-designed for converting electric drive power into a analogue gesture within the actuator-features erratic rollers assembled around the actuator ‘s extending rod that follow threads, which are preciesly machined on the inside surface of the actuator ‘s hollow armature. analogue motion is produced in accurate synchronism with the armature rotation .
“ The GSX40 … allow us to move our barrier up and devour faster with a higher total of duty cycles, ” Jempty said. “ The servomotor was specially helpful because it knows where the barrier is at all points in its mathematical process. With the old style you only knew if the barrier was up or down. ”
Since the curler screw mechanism features a relatively larger umulative reach coat, the actuators have a long functional life and can handle heavy loads at high speeds.

The bare invention requires about no care, even after high traffic volumes. The actuator delivers high speeds of up to 3000rpm, which approximately translates into 10 in./sec for the barrier. The compress system allows for senior high school torsion even at 0 speed, and the RSS-2000 was K-12 certified by the Department of State to stop a 15,000-lb fomite traveling at 50 miles per hour .
While a typical hydraulic barrier allows customes to manually raise or lower the barrier two to three times after a might outage, using the stored up pressure in the unit after a might outage, the actuator ‘s battery back up system allows for 300 or more uses after the power has gone out ,
