Indoor Information & Experience


Engineering drawings are not always available for an engineering review of our customers' existing structure being considered for fall protection, so "reverse engineering" is often required to determine the feasibility of attaching a system to the structure. Careful attention must always be emphasized to determine the load bearing capability of the structure, and our site survey technicians are experts in gathering the necessary information for our professional engineering staff to make a logical determination of feasibility.

With the unparalleled experience of thousands of different installations, we have professionally designed, feasibility tested and certified virtually every conceivable type of engineered mechanical bracket available to support our trolley beams.

Site Survey/Evaluation For Quote

The site survey and evaluation procedure requires an experienced professional to do the job right. The first step in the process is to establish a logical course for the trolley beam system to follow, which may include routing around obstacles. When a straight run of trolley beam is not possible, we have the experience and expertise to make adjustments by adding specially engineered curved inserts to the system to bypass obstacles.

In many of the thousands of facilities we have equipped, finding an acceptable common working height is challenging. We use state of the art laser measuring instruments to determine a logical and acceptable overall mounting height and routing for a proposed fall arrest system.

Extension Systems Out Of Existing Structure

Perhaps your application includes a tower or shed structure, but must also extend into an otherwise open area beyond that structure. For example, let's say you want to cover a train loading shed and several railroad cars on open tracks beyond the shed. Our trolley beam systems are designed to be capable of running a continuous and virtually uninterrupted course. Unlimited lengths of our patented integrated truss-supported trolley rail can be coupled to the shed or tower mounted portion of a system in a continuous uninterrupted length. We refer to these systems as "Combo Systems", with the extensions supported by vertical support columns once they exit the shed structure.

We have built thousands of Combo Systems, utilizing free standing vertical support columns approximately every 100 feet beyond the shed or tower to support the extensions beyond the structure. When necessary, we have modified overhead siding walls by adding a small neatly trimmed cutout directly above the trolley beam. After cutting through a sided wall, we often add new supporting steel around the neatly trimmed opening to minimize the aesthetic effect on the appearance of the original structure.


Our people will take the time to explain in simple, understandable language the "what, how and why" we are proposing for the system under consideration. One area where this is particularly necessary involves train and trailer loading facilities under older sheds and warehouses with low overhead ceiling heights. Trains and trailers have both gotten taller since the older facilities were constructed, and fall protection was not even considered when they were built. Despite the fact that adding a fall protection system further reduces the already minimal head clearance, the system is necessary to meet OSHA regulations.
