Systems are easily moved with a large forklift or the optional steerable rolling chassis package. These temporarily installed systems provide a fixed path of fall protection coverage up to 30° off center. Designed with one or two support columns with cantilevered headers, they provide easy access to the top of many types of vehicles.
