The company that made and installed an escalator at Coors Field in Denver that failed says overloading was the problem.

Trevor Nink is president of Kone (KOH'-nay) Incorporated and
says the overloading -- combined with a wire that inadvertently had
been misconnected -- allowed the escalator to speed up that night.

About three dozen people suffered injuries ranging from scratches to broken bones earlier this month when the escalator suddenly sped up as people were leaving the stadium.

Officials say the electrical problem probably caused a delay of about three-quarters of a second before a safety brake was applied.

They say under normal conditions that wouldn't be a problem, but the overcrowding gave the escalator a momentum that the brakes
couldn't handle.
