Roof top work can present a unique set of working conditions. The employee must be able to gain access to all areas of the roof yet must be protected from the edge. A fall restraint system is just one of the solutions to this type of problem.
Railcar and truck loading facilities may require interior or exterior fall protection systems. Interior installations can require an interface to the existing building for anchorage points. Frequently, exterior installations are not adjacent to an existing building. In these instances, a freestanding support structure must be designed and installed to serve as a custom anchorage point on which to mount the fall protection system.
Adequate clearance is also an issue for railcar and truck loading facilities. Proper engineering and consideration of the performance of the various components is critical to ensuring that the worker is brought to a complete halt before contacting a lower level or the ground.
I wanted to follow-up on the system installation. We are pleased with the outcome. Your crew was excellent; they arrived prepared for the cold weather work. The temperature here in Denver reach -17 degrees below zero the night before and never exceeded +7 while they were here. They completed the work without issue, cleaned up after themselves and provided us with superb training and recommendations. Thank you for completing the projects before the year’s end.

Each installation is unique and requires careful evaluation of the site and work specific parameters. Evan Fall Protection has designed railcar and truck loading facilities applications by utilizing single- and multi-span cable based systems supported on custom designed stanchions and foundations, structural steel trolley beam based systems and enclosed track, self-cleaning, low profile systems. Evan Fall Protection’s staff of licensed professional engineers has the structural and foundation expertise to analyze and certify the capacity of an existing structure or to design a custom structure to serve as a fall protection anchor point.
While there are variations in configuration, the typical bus is approximately 40 feet long and only 10 feet high. Workers on the top of a bus performing maintenance can be exposed to falls. As a result of the low working surface, particular attention must be given to the proper design of the fall protection system and selection of the user equipment as they can greatly affect the fall clearance distance. Oftentimes, this is further compounded when attempting to provide protection for more than one worker at a time.
Many bus maintenance facilities are in lightly framed structures that are composed of a roof system of open web joists and metal roof deck supported on steel beams and columns, or similar type structures. When the steel beams are spaced far apart, it creates an environment in which it can be difficult to design an effective fall protection system. Small diameter cables, such as 8mm or even 3/8″ can be ineffective in spanning long distances as they exhibit excessive deflection. This can be further compounded when in-line load arresting, or shock absorbing devices are incorporated. Only the more robust, large diameter cables or trolley beams should be considered for such applications. Both of these types of systems, however, carry the disadvantage of imparting relatively high loads to the supporting structure. Evan Fall Protection’s staff of licensed professional engineers has solved bus maintenance fall protection problems in the past, are aware of the intrinsic problems and are capable of designing and installing custom systems that address these issues.
Evan Fall Protection’s comprehensive approach to fall protection ensures the highest level of worker safety, OSHA compliance and peace of mind.
Overhead Rigid Rail Systems can be installed from overhead to near ground level elevations. The rail systems provide the option for an enclosed or open track. The enclosed track features single, dual or triple tracks permitting users to bypass one another.
Overhead Cable Systems can be installed from overhead to ground level elevations. The cable systems are economical and manufactured from stainless steel. They offer the user exceptional functionality through its free flowing bypass capability and ability to navigate corners.
Evan Fall Protection has created a proven process for distinct fall protection and access solutions. Our Portable Access Systems can be customized based on the customer’s application requirements and design constraints. The systems can be fabricated at various heights/widths with diverse wheel styles to meet any site conditions.
