Its purpose is to connect the load to the beam and beam to the crane hook with the help of lifting accessories. Let our engineering team help design your custom spreader bar. Let's learn what an absolute expert has to say about lifting beams, spreader bars, and the design thereof. After Mr. Duerr explains the mathematical formulas behind reliability, he emphasizes that "once a design provides a reliability of 99.9% for the given service conditions, any further increase in the design factor does nothing to improve the reliability or safety of the lifter". stress analysis of precast prestressed concrete beams. Some bending may be experienced as the forces F1x and F2x are acting at the hole of the pad-eye, which is offset from the centerline of the spreader by some distance. It serves a dual purpose, in that it assists firms to extract more fossil fuels than beforehand was potential, and it provides a safer, more eco .

In response, a large below-the-hook-lifting devices market has grown supporting projects with some exceptional solutions (see. Structural Reliability The "reliability" of a lifter is the probability of survival subject to the statistics of loading and strength based on the chosen design factor. Fig 3: Forces and moments on lifting beam. In. Our lifting spreader beams and bars allow you to turn a crane hook into a multiple point lifting tool. Generally, a spreader beam would not be as prone to the 'suspended beam' effect as a beam under its own self weight alone, since the end restraining torques for a given degree of rotation will generally be greater, (assuming that the lifted load is supended from lifting lugs located below the beam, and hence the lever arm of the couple is greater). Calculating the Weight of a Load. 5. Also in their use of materials, so theyre typically smaller, lighter, and economic to design and manufacture than a lifting beams. Universal provide one tone spreader bar which is in stock and available worldwide via Universal engineering distributors and rental partners for any lifting equipments in a cost effective manner.

They are ideal for: Construction sites, industrial fabrication plants, marine and shipping industry, and petrochemical facilities. Www Excelcalcs Com Lifting Lug Calcs Xls. The service class designates the number of load cycles, or fatigue life for which a beam is designed. The exemplar calculations shown are for a load of 30 tons having a span of 20 ft to be lifted using a spreader bar of cylindrical pipe, made of standard ASTM A53B carbon steel. Pipe and plate is considered as a homogenous section. Note: According to ASME B30.20, proof testing is only a recommendation, not a requirement. Along with this we do spreader beam calculation and design. Phone support is available at 800-727-6355. This efficient method of rigging redirects compression forces away from the load and in to the spreader bar. Spreader beams are some of the most popular below the hook lifting devices in the material handling industry. Step 3: Determine the Weight of Object. 1 DESIGN DATA.

I read this article, it is very well explanation. It checks the crane lifting capacity, tilt angle, and calculates the lift point load. Proof Testing If operating in the USA, OSHA's rigging equipment regulation (29 CFR 1926.251) requires a 125% proof test for "lifting accessories". A spreader beam is designed to take primarily compressive loads, as can be seen in the figure above. Though, because of many factors, structural design factors are benchmarked at different levels in design standards around the world. This training module for the US&R Sructural Collapse Technician use tag lines. Depending on your jurisdiction, there are design considerations, guidelines, and regulations. The non-slip hook design fits snug into most battery lifting holes. In order to accommodate the overhead slings, spreader beams require more headroom than a lifting beam.Possibility of spinning in the case of long beams or uneven loads. All loads to be lifted or moved must be assessed for weight, stability and rigging points.

If you are looking for more information on BTH-1, feel free to contact us, or you can wait for future articles that will discuss applying BTH-1 to design of lifting beams and spreader bars in greater detail. Lifting beams are universally applied gear used widely in various types of lifting operations, onshore and offshore. Im planning to start my own site soon but Im a little lost on everything. This type of lift subjects the beam to flexure (bending) and shear, with bending stress and lateral torsional buckling being the primary modes of failure. Design and Construction of Lifting Beams DAVID T. RICKER Lifting beams (also known as spreader beams) are used to assist in the hoisting process. The spreader bar increases load stability by raising the suspension point away from the center of gravity. They understand the tasks and issue you face everyday and teach the skills you need to succeed. Enter the email address you signed up with and we'll email you a reset link. 1. Fortunately, on earth, physics does not change depending on your locale, so carefully crafted design considerations in one jurisdiction should "work" in others. Modulift modular spreader beams provide the ideal solution - versatile and cost-effective, the range has capacity from 2 to 3000t with spans up to 100m/330' About. . ITIs Help Center is a robust support tool providing detailed articles on all our products and services.

Two lifting lugs on the top of the beam attach to the legs of a chain sling or synthetic sling at a particular angle designed to ensure pure compression. Dear Weerawut Ordinary Lift Plan Elements Once a lift has been planned and approved, the appropriate rigging equipment, Variations in the design of the multi-lift spreader bar evolve over a period of time as requirements and technology change and the demand for a more efficient product is desired. Conversely, for a telescopic spreader bar with a centre pick point and two slings out to the ends of the spreader bar the loading on the beam would be primarily compressive, although if the ends of the spreader bar are set up such that bending is applied to the ends of the spreader bar, then a combination of load calculations must be utilized.
