The Tuff Built by Diversified Cube Portable Anchor System uses a concrete filled steel box as ballast to support fall protection davits and/or rails which are positioned over an elevated work area.  With a wide variety of available base, mast, and outrigger options, Cube style mobile anchor systems can be easily moved between work areas using suitable material handling equipment.

Designed to provide an overhead anchor system  where and when you need it, the Cube mobile fall protection system sets up quickly and ensures a stable, safe platform for employees working at heights.  Ideal for outdoor applications lacking overhead support structure, the Cube fall arrest system comes in a variety of stock configurations to meet your fall protection needs.

Please Note:  The tables below show standard stock sizes/configurations, but if your application requires modifications to an existing design, contact us to discuss your specific needs.

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.
