Weighted Base Anchors

Weighted Base Anchors

A freestanding counterweight anchor can provide a temporary tie-off point for personnel performing work on flat roofs or structures.  45 pound plates are added to rubber trays that are connected to a shock absorbing tie-off post. Once set-up is complete, simply attach your shock absorbing lanyard, self retracting lifeline or rope grab and lifeline and you are ready to go.  Weighted base anchor systems require no penetration of the roof’s surface, reducing the possibilities of roof leaks and voided roof warranties.   Weighted base anchor systems can be used on concrete, single ply membrane, bitumen membrane, asphalt sanded and asphalt stone roofs with a maximum of 5 degrees of slope/pitch.

Design Considerations

Weighted Base Anchor Design Features This anchor incorporates a revolutionary shock absorbing system called LEAP™. The LEAP™ post (with tie-off point) has an integral energy absorber that deploys in a controlled manner to absorb the forces generated during a fall. This specialized design provides added safety to the attached worker and better distributes the forces to the anchor and structure. By limiting the forces this way, the integrity of the roof is also preserved. Due to the modular design of weighted base anchors, installers will never have to lift more than 45 lbs. (20.3kg). In some applications, the entire system can be lifted (by forklift or crane) into place for instant set-up and use.

OSHA Regulations

  • Weighted Base Single Point Anchor OSHA Regulations
    • 1926.502(d)(15) Anchorages used for attachment of personal fall arrest equipment shall be independent of any anchorage being used to support or suspend platforms and capable of supporting at least 5,000 pounds (22.2 kN) per employee attached, or shall be designed, installed, and used as follows:
    • 1926.502(d)(15)(i) as part of a complete personal fall arrest system which maintains a safety factor of at least two; and
    • 1926.502(d)(15)(ii) under the supervision of a qualified person.
  • Personal Fall Arrest Systems
    • 1926.502(d)(15) Personal fall arrest systems, when stopping a fall, shall:
    • 1926.502(d)(16)(ii) limit maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness;
    • 1926.502(d)(16)(iii) be rigged such that an employee can neither free fall more than 6 feet (1.8 m), nor contact any lower level;
    • 1926.502(d)(16)(iv) bring an employee to a complete stop and limit maximum deceleration distance an employee travels to 3.5 feet (1.07 m); and,
    • 1926.502(d)(16)(v) have sufficient strength to withstand twice the potential impact energy of an employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system, whichever is less.
