Rigging is a very important process in most of the businesses today, especially construction and shipyard industries. Rigging can be referred to any hardware and/or equipment that the businesses use to attach heavy objects to the device that will lift it. It is also defined as the process or an art to hook the load or the heavy object to the lifting device by using the most durable slings and other required hardware/equipment.
Jack Rubin & Sons, a leading supplier of rigging, safety and expendable equipment to the industry has opened a new location. The new facility in Atlanta will be within arms reach of the entertainment district which includes Pinewood Film Studio, Atlanta Film Studio, Screen Gems, Raleigh Studios, and many more. In addition, the southeast location will speed up the time getting products and supplies to the Florida, North Carolina, Tennessee and Louisiana markets.
Atlanta is a perfect fit for the new location. Due to the aggressive state incentives there are a large number of productions constantly working in the area. “It is a big city that has a lot of resources and southern hospitality,” said Michael Rubin, president and CEO. Many of their existing clients have relocated to the area to keep up with the production work. This will enable JRS to maintain the high level of customer service their loyal clients have experienced for decades on the West Coast.
Jack Rubin & Sons new facility location: 775 Atlanta South Parkway, Ste. 350, College Park, GA 30349. Continue reading

“The Pro Rigger” by Mike Parnell
As you know in ASME B30.9 SLINGS and other industry documents that highlight sling capacities, there are stated design factors. Also in B30.26 RIGGING HARDWARE which covers shackles, swivel hoist rings, eye bolts, rigging blocks and the like lists design factors between 4 and 5.
The first primary reason is to account for some measurable amount of wear to the sling or component during its lifespan. This wear will reduce its overall minimum breaking force (ultimate strength). This may occur in the form of metal loss in links of a chain sling or in the bow or pin of a shackle. The respective manufacturers have pre-calculated the amount of loss they can live with before calling for the equipment’s removal from service. Read more…
