Peak Racks' 6 bike single-sided rack has nearly the same footprint 109" wide x 72" deep (with bikes) as a UW duckbill, which is 120" wide x 6" deep. http://www.peakracks.com/rack-info/dimensions/
this would increase capacity by almost 10%, but only for single-side racks (because double-sided use of Peak's racks is simply putting two single-sided racks back to back, whereas double duckbills face different directions on the same base, meaning a double duckbill is only 10'6" deep, rather than 12' (twice the 6' depth of two single-side racks). See picture 10/18 "On-Campus Bike Rack in use" here: http://www.peakracks.com/bicycle-racks/commercial-campus-racks/ And a 6 bike single-side Peak rack costs about five times as much as the equivalent duckbill from UW's machine shop (and three times as much as a UW duckbill from a local outside vendor) http://www.peakracks.com/rack-info/price/ For the price of the Peak racks, I could get Ultra Space Savers from Dero: http://www.dero.com/products/ultra_space_saver/ultra_space_saver.html and we've discussed doing just that for some very high demand locations on campus (e.g. Memorial Union), because I could double capacity over the most efficient layout of UW duckbills. And it may still happen after many of the current construction projects are done, but that still means spending four times as much per bike to park twice as many bikes. Again, I am happy to assess any/all alternatives to our racks, because we would always like to do better. But cost is a significant consideration. We currently pay about $30/bike for UW duckbills from our own machine shop. Even inverted U racks spec'd for new construction that are sourced from a local outside vendor cost about $80/bike. Everything else discussed on this thread so far costs ~$150/bike and up. When you're trying to park 10,000 bikes or more, that adds up fast. chuck ---------------- Also found a US manufacturer's patented version of a staggered height rack "Specifically designed for space efficiency, Peak Racks Campus Racks feature One Side Loading with a Vertical Stagger to eliminate handle bar tangles. The vertical stagger also allows each slot in the rack to be used simultaneously. Peak Racks bike racks offer superior security by using Individual Locking Bars, which allow the frame and wheel of each bike to be individually locked with a U-lock, or cable lock." http://www.peakracks.com/bicycle-racks/commercial-campus-racks/ Jim Bikies mailing list [email protected] http://lists.danenet.org/listinfo.cgi/bikies-danenet.org _______________________________________________ Bikies mailing list [email protected] http://lists.danenet.org/listinfo.cgi/bikies-danenet.org
