SL 75 Aerial Ladder

The SL 75 is a single-axle aerial ladder that delivers the strength of a full-sized truck in a compact, highly maneuverable package. Built with huck-bolted construction and a 3:1 safety factor, it’s one of the strongest aerials in the industry. With a 1,000 lb dry/750 lb wet tip load, and an electrically controlled nozzle, the SL 75 provides reliable reach and water delivery without compromising agility.

Designed to drive like a pumper but perform like a full aerial, the SL 75 is versatile enough for a wide range of scenarios. Despite its smaller footprint, it offers generous compartment space for gear, tools, and rescue equipment. Whether navigating narrow streets or responding to dynamic rescue calls, the SL 75 gives departments the flexibility, strength, and dependability they expect from a Sutphen.
