Below is a list of Narrow Aisle Forklifts manufacturers from Hamilton, Ohio. Narrow aisle forklifts are specifically designed to operate in constricted and congested areas. They are able to maneuver down isles 8 to 10 feet wide, while standard models need at least 11 feet to make turns. The forks are at a right angle to the truck’s body, and are therefore able to pick up loads to the side without turning.
