An engine company’s minimum complement of ground ladders, as dictated by National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus (2016 ed.), comprises one extension ladder, one straight ladder equipped with roof hooks, and one attic ladder.
But, sometimes, those ladders don’t fit a situation where firefighters find themselves because of a tight space, inadequate room, hard-to-access ingress, uneven surfaces, or another type of issue. However, there are ladder types that go beyond the typical ladder complement to fit those situations.

Combination Ladders
Randy Vandersee, plant manager of Duo-Safety Ladder, says Duo-Safety makes two versions of an A-frame or combination ladder that work well in unusual circumstances. “Our 300A model works as an extension ladder where the fly slides up, as well as an A-frame ladder that has a spreader assembly similar to a step ladder,” Vandersee says. “This ladder is available in a six- to nine-foot length (six feet A-frame and nine feet extension), an eight- to 13-foot length, and a 10- to 15-foot length.”

Duo-Safety also makes the model 35B, a traditional jackknife-style combination ladder, Vandersee points out. “It’s often used to bridge a fence or wall,” he notes. “It folds in the center and comes in six- to 12-foot, seven- to 14-foot, and eight- to 16-foot lengths.”
Sam Cramer, chief executive officer at Alco-Lite, a product line made by Sam Carbis Solutions Group, says that Alco-Lite makes the CJL series ladder, which is a short extension and A-frame combination ladder. “We’ve made the CJL series for years, and it has traditionally sold well in the New York and Pennsylvania areas,” Cramer says. “It can be an A-frame or stepladder when needed or be reconfigured into an extension ladder in 10-, 12-, 14-, and 16-foot lengths. In the A-frame configuration, it runs from six to 10 feet high.”
