Articulating Jib Cranes & Trolley Fall Arrest Systems

Articulating jib and folding trolley systems are rigid rail fall protection solutions that can be moved and retracted as needed. Thanks to their fold-away design, articulating systems are ideal for crane bay applications. Unlike fixed systems that interfere with the movement of an overhead crane, fold-away fall protection systems can be deployed as needed, then retracted when overhead equipment is in use.

Regardless of your crane’s unique path through the plant or the footprint of equipment and obstructions in your crane bay, engineered fold-away or articulating rigid rail fall arrest systems offer solutions. Discover the perfect blend of OSHA compliance, safety, and productivity with rigid rail fall protection from DFP.

Each system DFP installs is the product of an on-site engineering visit, during which safety experts watch the interaction of your equipment and personnel to create a fall arrest system customized to your needs.

Diversified provides a turnkey, one-stop shop for your fall protection needs, including design, engineering, fabrication, installation, inspection, and repair. Diversified Fall Protection offers decades of experience in specialized fall protection systems, providing you unparalleled expertise.

Falls are the leading cause of occupational injuries and fatalities. As a result of increased insurance and workers’ compensation premiums combined with legal fees and other costs, fall protection is a vital business investment. Ensure OSHA compliance, worker safety, and peace of mind with an articulating jib or fold-away fall arrest system from the safety experts at Diversified Fall Protection.

Design Considerations

For both articulating jib and trolley rigid systems, it's important to assess the total fall protection coverage area needed to protect workers as they perform routine maintenance and daily duties. A system that can support one worker at a time or multiple users with bypass capability is important to consider when developing specifications and design features.

For jib systems, the distance between building support columns must be taken into consideration. For beam trolley rigid fall protection systems, ascertaining the height of the crane as well as the crane design style (underhung or overhung) will factor into the final system design.

OSHA Regulations

Personal Fall Arrest Systems:  

  • 1910.140(d)(1) 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) System use criteria. The employer must ensure that:
  • 1910.140(d)(2)(i) 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.
