Rigid Rail L and T Style Support Column Fall Protection Systems

Trolley style rigid rail support column fall protection systems are typically utilized for outdoor applications where total fall clearance is minimal.  Trolley style L and T style support column systems minimize fall distance and deflection, and require smaller foundations.  Rigid rail support column systems also easily accommodate multiple users, making them ideal for many outdoor fall protection applications. Available in both permanent and portable configurations, Rigid systems are common solutions for truck, train, and heavy equipment maintenance, as well as loading and tarping applications.

Each system we install is the product of an on-site engineering visit where our safety experts watch the interaction of your equipment and personnel to create a custom solution. Our turnkey approach means you can rely on one company to engineer, fabricate, install, and re-certify a custom fall protection solution that provides years of safe and reliable service.

Remember, falls are the leading cause of occupational injuries and fatalities each year.  From a business standpoint, the increased insurance and workman’s compensation premiums combined with the legal fees associated with a fall can have dire consequences.  Ensure OSHA compliance and worker safety with a rigid rail system from the safety experts at Diversified Fall Protection.

We are a complete turnkey provider of OSHA compliant rigid rail fall protection systems and have years of experience designing and installing gallows systems for fall arrest applications. Contact us for expert assistance with your fall arrest, fall restraint and fall protection requirements

Design Considerations

One of the first design considerations that needs to be examined when developing a rigid rail support column system is size of the planned coverage area, or more simply put, the total length of the system. With proper planning and consideration, Rigid Rail L and T-Style Systems can span work areas in excess of 1,000 feet. For rigid gallows systems designed for rail applications, specific railroad company clearances must also be taken into consideration. These systems come in a variety of configurations, including L, T, and U. A T gallows system provides dual coverage for two trucks or side by side rail spurs. When designing a rigid gallows system, soil compaction levels and frost line levels must be given special consideration to ensure proper foundation design. Finally, care must be taken to consider total fall clearance; the system must be able to arrest a fall before a worker comes into contact with structure or the ground below the designated work area.

OSHA Regulations

  • Personal Fall Arrest Systems:  System performance criteria. In addition to the general requirements in paragraph (c) of this section, the employer must ensure that personal fall arrest systems: 1910.140(d)(1)(i)
  • Limit the maximum arresting force on the employee to 1,800 pounds (8 kN); 1910.140(d)(1)(ii)
  • Bring the employee to a complete stop and limit the maximum deceleration distance the employee travels to 3.5 feet (1.1 m); 1910.140(d)(1)(iii)
  • Have sufficient strength to withstand twice the potential impact energy of the employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system; and... 1910.140(d)(1)(iv)
  • Sustain the employee within the system/strap configuration without making contact with the employee's neck and chin area. 1910.140(d)(1)(v)

If the personal fall arrest system meets the criteria and protocols in appendix D of this subpart, and is being used by an employee having a combined body and tool weight of less than 310 pounds (140 kg), the system is considered to be in compliance with the provisions of paragraphs (d)(1)(i) through (iii) of this section. If the system is used by an employee having a combined body and tool weight of 310 pounds (140kg) or more and the employer has appropriately modified the criteria and protocols in appendix D, then the system will be deemed to be in compliance with the requirements of paragraphs (d)(1)(i) through (iii). 1910.140(d)(2)   The employer must ensure that:

  • On any horizontal lifeline that may become a vertical lifeline, the device used to connect to the horizontal lifeline is capable of locking in both directions on the lifeline. 1910.140(d)(2)(ii)
  • Personal fall arrest systems are rigged in such a manner that the employee cannot free fall more than 6 feet (1.8 m) or contact a lower level. A free fall may be more than 6 feet (1.8 m) provided the employer can demonstrate the manufacturer designed the system to allow a free fall of more than 6 feet and tested the system to ensure a maximum arresting force of 1,800 pounds (8 kN) is not exceeded. 1910.140(d)(3)
  • Body belts. Body belts are prohibited as part of a personal fall arrest system.
