Articulating Jib Boom and Fold-Away Fall Arrest Systems

Articulating Jib and Folding Trolley Systems are ideal fall arrest systems for crane bay applications. Unlike fixed, rigid beam systems that may interefere with the movement of an overhead crane, fold-away or articulating fall protection systems can be deployed as needed and retracted when overhead equipment is in use. Regardless of your crane’s unique path through the plant, or the foot-print of other equipment and obstructions in your crane bay, an engineered, fold-away or articulating rigid beam fall arrest system offers the perfect blend of OSHA compliance, safety, and productivity.

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, and 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 Articulating Jib or Fold-Away fall protection system  from the safety experts at Diversified.

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

Design Considerations

Articulating Jib and Trolley Rigid System Design Considerations For both articulating jib and trolley rigid systems, one of the most important design considerations is assessing the the total coverage area that will need fall protection to protect workers as they perform routine maintenance and daily job duties. The number of users and the potential need for by-pass capability is also an important factor when developing system specification and design features. In addition, for jib systems, the distance between building support columns must be taken into consideration. For trolley beam rigid fall protection systems, ascertaining the height of the crane and the crane rails, as well as crane design style (underhung/overhung) will factor into final system design.

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.
