minimum weight supporting capacity of a certified anchorage point

Dallas, TX 75254 When considering non-certified anchors, remember that the problem isn’t the capacity of the connectors (since they would be rated to 5,000 lbs. This is an example of OSHA and ANSI trying to get folks to think beyond the … You may be eliminating perfectly good anchor points where it’s already difficult to achieve proper fall protection. Video Interop Server capacity. In contrast, OSHA regulation 1910.140 (c) (13) (ii) requires that certified anchor points only need to be capable of supporting two times the load applied to the anchor point in the case of a fall. q/p = W/A. This capacity, certified by the manufacturer, shall be based on the manufacturer's specifications with a 5 to 1 safety factor for all components. (22.2kN) per worker or meet OSHA 1926.502 requirements for a safety factor of two, such as an I-beam or other support structure. Increased weight leads to increased risk in the event of a fall. The values in Tables 4.2 and 4.3 are generally associated with a safety factor of 3 (Naval Facilities Engineering Command, 1996) and are considered appropriate for non-continuous or independent spread footings supporting columns or piers (point loads). The anchorage should be rigid, and should not have a deflection greater than .04 inches (1 mm) when a force of 2,250 pounds (10 kN) is applied.” Ultimately, selecting the best anchor point is all about determining what type of anchorage point is most suitable for the work you need to carry out, as well as what amount of weight it can support. to use fall protection, but 130 lbs. This number is representative of the anchor achieving the required 2:1 strength ratio required by OSHA and ANSI. Most people relying on safety personnel to interpret the OSHA standards will think it sounds plausible enough and find ways to be compliant.

Ideally, these systems should always be accompanied by professional engineering documentation so that it can be reviewed and re-certified by the original design engineer as the system is built. The anchorage connector is designed to be used in temperatures ranging from -40ºF to +130ºF (-40°C to +54°C. Of course, there are regional factors at play as well. The size 6.5-inch hoverboards are ideally designed mainly for the ‘Casual Riders’. should keep the forces on the body below that 1800 lb limit. A safety factor of two should be applied (i.e., 12 kN or 2,700 lb). We usually tell folks that if they can imagine dangling a Ford F150 from the anchorage spot, then it'll probably pass the test. Add anchor points. Anchor point selection can be difficult. Figure 2 illustrates components of the D-Bolt Anchor. 1 Horizontal Lifeline Systems certified by a professional engineer should be designed according to CSA Z259.16-04, Design of Active Fall-Protection Systems. If the system passes, then, a safety factor of two applied to 2,520 pounds would be approximately 5,000 pounds. In fact, when testing systems under OSHA, you are required to use a weight of 220 pounds (plus or minus 3 pounds) at a free fall of 6 feet [29 CFR 1926 Subpart M Appendix C]. The anchor point, also referred to as the tie-off point, is a secure point of attachment for connecting devices and must be capable of supporting 5,000 lbs.

Anchor point selection can offer limited options when trying to comply with OSHA. Traditionally manufacturers applied a static load to the anchor, which placed the least amount of stress on the product. Having a weight capacity like that a 6.5-inch hoverboard can reach the maximum speed of 7.5 mph which we think is ‘AMAZING’. Critical section for maximum bending moment is taken at the face of the column. Note that there is a small selection of shock absorbing devices that can allow a worker under 130 lbs. However, 5,000 pounds is where many people stop reading. B) Two times the maximum arresting force for certified anchorages. 3.
