SLR 108 Aerial Ladder

The SLR 108 is Sutphen’s tandem axle rear mount aerial ladder, offering departments a powerful alternative to the traditional midmount design. Built on a tandem axle chassis with huck-bolted aerial construction and a 3:1 safety factor, the SLR 108 delivers strength and dependability for high-demand responses. Its 108-foot ladder operates without a torque tube and is stabilized by two sets of underslung jacks, while a narrow 16-foot jack spread provides a secure setup in tighter spaces.

With 115 feet of ground ladders and a full suite of heavy-duty features, the SLR 108 is designed for departments that need reach, reliability, and maximum equipment capacity. Whether for urban fire response or complex rescue scenarios, the SLR 108 stands ready.
