Articulated Ladders
An Articulated (multipurpose) Ladder is a portable ladder with one or more pairs of locking hinges which allows the ladder to be set up in several configurations such as a single or extension ladder, with or without a stand-off, a stepladder, a trestle ladder, scaffold or worktable (to learn more about ladders, visit the American Ladder Institute).
Articulated ladder with locking hinges
- Each pair of articulated joints in the ladder can be locked in one or more positions to accommodate the various configurations.
- The locking positions of the hinges allow set-up at the proper angles to accommodate each configuration that the manufacturer has designated.
- When set up in the stepladder configuration, articulated Ladders range in size from 3 to 15 feet maximum.
- When set up as a Single or Extension Ladder, Articulated Ladders may have a length of no more than 30 feet.
- Heavy duty, extra heavy duty, and special duty types (I, IA, and IAA) multipurpose ladders are designed for one or two persons (to visit another website with good information about ladders, visit Werner Ladders).
