"The VMAG linear induction gate operator is the most significant innovation for gate automation in decades and represents a paradigm shift in technology by fundamental- ly changing the way gates operate," O'Connor stated. "The VMAG has no gear boxes, hydraulics, hoses, pinch wheels, cables or chains, which typically become maintenance issues over time and ultimately fail. VMAG uses only magnetic coupling to drive the gate without actually touching it, and operation is very smooth and free of wear related issues or other mechanical limitations." VMAG can be adapted to new or existing slide gates of any weight or length, he noted. "Anyone who has waited to drive through an airport operations area or other security gate knows that the slower gate speeds impede authorized personnel, since only one vehicle is permitted access at a time," said O'Connor. "Time is mon- ey, and the enhanced throughput and return on investment can be dra- matic with higher operating speeds. VMAG speed may also help reduce VMAG has received independent testing authorization from Intertek Testing Services NA, Inc. (logo shown above), allowing formal application of the UL 325 certification label to the company's VM 1220 and VM 1420 models. The company feels this advancement offers the potential for additional opportunity, especial- ly in areas where a listing may be required. At top, the patented design utilizes proven linear induction motor technology to open and close security gates at speeds up to 8 feet per second (each gate cycle is programmable to suit the specific application). The electro-magnet- ic drive is also "green" and uses no hydraulic fluids, oils, lubricants or moving parts, providing superior performance and reliability, without environmental consequences. costly tail-gating infractions and oth- er security breaches associated with slow moving gates. VMAG's unprece- dented performance is also complete- ly programmable with variable speed control to accommodate the specific needs for each application." The patented design utilizes prov- en linear induction motor technology to open and close security gates at speeds up to 8 feet per second. The electro-magnetic drive is also "green" and uses no hydraulic fluids, oils, lu- bricants or moving parts, providing superior performance and reliability, without environmental consequences, O'Connor said. "Interestingly, VMAG utilizes similar technology found in many high-tech, industrial and military applications like high-speed roller coasters, trams, trains and baggage handling systems whose motors are entirely magnetic, resulting in reli- ability as well as fast but smooth oper- ation," he said. Although the rapid gate speed is the primary factor in allowing quicker ingress and egress, O'Connor noted that both the open- ing and closing rates, or a combi- nation of the two, are completely programmable to suit the specific application. Each gate cycle may be programmed to suit the individual requirement, i.e., rapid open, slower close, etc. "NASA has experimental launch systems and the U.S. Navy plans to replace steam catapults on aircraft carriers, as well as develop new weapon systems using electro- magnetic energy. VMAG patented this technology to completely change gate automation," O'Connor added. "It's pretty amazing to see a VMAG and how easily it propels standard security gates, but we're also seeing an increase in special projects involving longer openings and gates with substantial mass and there appears to be no practical limitations for the operator," O'Connor said. "VMAG is frequent- ly specified for high-end projects requiring access control point integration and offers develop- ment services for custom commu- nication and logic controls for these applications. VMAG is compati- ble with all existing access control devices and can be specified for new construction or retro-fitted to accommodate existing gates. "VMAG Gate Operators provide a return on investment for high-volume applications requiring enhanced security, throughput efficiency and reliability, O'Connor noted. continued on next page Internal or External Mounting Options Hydraulic Gate Closer and Hinge Self-closes gates up to 260 lbs • Hydraulic closer & hinge all in one small, powerful package! • Dual bearing glide system for consistent superior performance • High strength aluminum — tested to 500,000 cycles • ADA compliant • Multiple adjust options — closing speed and final snap action • Powerful hydraulics • 1,000 Pound Point Load • Highly tamper resistant • Maintenance free – no messy grease P: (714) 677-1300 E: info@ddtechusa.com www.ddtechglobal.com
