The fifth new Spartan/Crimson 103′ rear mount aerial in Chicago will be assigned to Truck 59. That makes Truck Companies 9, 31, 51, 56, & 59 the recipients of the five aerials that have been delivered to date. Each of these companies currently runs with a 1996 Seagrave except Truck 51, which has a 1995 Seagrave, the oldest ladder in front line service in Chicago. After these new rigs go into service, there will be two remaining 1996 Seagrave trucks that are assigned to Trucks 61 and 62.
As a side note, there are three 1996 HME 1871/Simon-LTI 100′ tower ladders currently assigned to Tower 21, Tower 37, and Tower 39. Due to an accident with their 2002 Pierce Dash Tower Ladder, Tower 34 is running again with their 1988 E-ONE Hurricane 95′ tower ladder.
