Card key operated chain link sliding gates Inquiry (采购产品): Card key operated chain link sliding gates I am designing a 6' high sliding security gate system to secure two 70' wide street openings in conjunction with a major construction contract in Long Beach, CA. Particulars: Each opening will require 2 sliding gates, meeting in the center of the road. Each gate would need to be 35' long exclusive of the gates supporting structure. The gates will roll on an inverted "V" or may use rubber faced steel wheels to roll directly on the surface. The rolling surface will be on a 2% grade. Gate operation: There will be two gated openings, one at each end of the secured area, through which the street will pass. The street openings will be approximately 60' apart, measured along the street. Each opening will have one set of 2 gates. Vehicles/people will pass through BOTH sets of 2 gates. Each set of 2 gates (The 4 gates will operate with a card reader, which will open the second set of 2 gates fully THEN open the first set of 2 gates. If a person or vehicle is within the gates area and the gate attempts to close on the obstacle, the gate(s) will immediately reverse to it fully open position. In any case, after a variable preset time after the gates reach full open position, the gates will automatically close. The designation of "first set of gates" and "second set of gates" will be reversed based on which of the two card readers are activated. As such, thewre is a need for two card readers, one on each side of the secured area. I also need to include specifications (material, fabrication, operation, safety devices, installation, etc., for the sliding gates as well as for the card key system. I would appreciate if you could forward specifications for the sliding gates and the card readers, inlcuding any installation details and recommendations. Please note that the requested information is is needed within by November 11, 2004 or sooner. **** Hidden Message ***** Carmen Gendusa CA 92868 USA Company: DMJM+HARRIS Title: Engineering Manager Phone: 714-567-2616 Fax: 714-567-2441 E-mail: carmen.gendusa@dmjmharris.com **** Hidden Message ***** carmen.gendusa@dmjmharris.com |
