In response, a large below-the-hook-lifting devices market has grown supporting projects with some exceptional solutions (see Modulift, Liftmax, Caldwell , Tandemloc, Bushman, and Peerless to name just a few). Toolbox Talks are an effective way to refresh workers safety and health knowledge as well as to promote safety culture daily. Check for axial compressive stress : - Total Equipment weight be lifted = W = 286000 Kg Load at each end = W/2 = 143000 a = 60 Shock . Though, because of many factors, structural design factors are benchmarked at different levels in design standards around the world. The difference lies in the way the forces are transmitted. About Us; . 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. he purpose of a design factor is to compensate for unknown load characteristics such as its weight. - Before . A spreader beam is designed to take primarily compressive loads, as can be seen in the figure above. It is the fundamental concept of the spreader beam, a mechanical structure that separates two legs of a sling, grommet or chain, all of which could only workat a straight tension and converts them into two suspended elements separated by a certain length and they spread the load between them. This Romano . As a broad distinction, in their purest forms: However, the primary load on the spreader is compressive stress. Spreader beams convert lifting loads into compressive forces in the beam and tensile forces in the slings. Service Classes 1 through 5 cover load cycles from 20,001 through 2 million load cycles. ITI maintains some of the industry's most highly-regarded experts in cranes, rigging, and wire rope. The next step is the calculation of stresses. The Dynamic Hook Load (DHL) is determined for this and using a simple mathematical formulation, the sling loads are determined. BTH-1 addresses design requirements including: While BTH-1 is broad in its coverage of design requirements for below-the-hook lifting devices, only portions of the design standard are applicable to spreader bars and lifting beams, in particular beam classification and the structural design requirements. Designing and Manufacturing Modular Spreader Beam Systems for a Cost-Effective, Safe Lift. Refer to the Manufacturer's Specifications or Catalog Data. d= = = 12.07 in. The following chart shows a comparison of a W-Beam lifting beam with lifting capacity based on simple bending stress calculations vs calculations that account for buckling per ASME BTH-1. sealed drawings and calculation sets like the ones shown below. the Checklist for Lift Planning and Weather Factors exhibits, found in the Lifting Safety Subject Area, as tools for evaluating the area of operation and potential. hbspt.cta._relativeUrls=true;hbspt.cta.load(78935, '160b9bb8-ddde-4c01-8b52-10a26747345d', {"useNewLoader":"true","region":"na1"}); Lifting beams and spreader bars have become an integral part of complex crane, rigging, and lifting activities. Step 3: Determine the Weight of Object. The spreader experiences the following stresses: Fig 6: Bending moment due to offset of force from centerline. Spreader bars are the best choice for loads where the lift points are far apart and load control is important. The ITI Learning Hub delivers a robust curated library of over two thousand on-demand courses to fit the needs of your diverse load handling workforce. Lifting beams are universally applied gear used widely in various types of lifting operations, onshore and offshore. For lifting beams that are subject to flexure, ASME BTH-1 has calculations that define the maximum allowable bending stress based on beam geometry, material properties, and lateral bracing spacing (the distance between braces that resist lateral displacement of the compression flange or twisting of the beam cross-section). Personnel qualification is available. Spreader bars can be made in a variety of lengths, connection types, & capacities. Looking for Custom Design Lifting Equipment? Following are the loads which affect the spreader: The angles of the slings 1 & 2 (in figure 1) made with the vertical must be less than 45 degrees (16.3.4.2, DNVGL-ST-N001).

Emphasis was made to focus on the areas of BTH-1 that apply to these devices. 6. They are suspended by a crane from two slings and normally have two to four bottom slings attached for rigging to the load. If you have a unique design challenge where you could use some engineering assistance, please contact us to see how we can help you. As can be see from the allowable stress plot, the short beam is permitted to achieve full bending stress (with safety factors), but at a certain point, the allowable bending stress is reduced, to account for the buckling strength of the beam. Applications that may involve non-standard rated capacity, lengths, connection types, coatings, inspection, testing, marking, and alternate industry standards. How Many Planes Does Yeti Airlines Have, 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". Let our engineering team help design your custom spreader bar. With all the above checks performed, a complete design assessment of a spreader for a specific lifting operation can be done. Fig. DESIGN FACTOR DESIGN FACTOR made up from Tilt & Yaw factor DO YOU INTEND TO USE A SPREADER BAR?

We will gather some specific information about your crane and rigging environment, safety considerations, etc. According to BTH-1 calculations, the short beam can be loaded to full yield strength (accounting for safety factors), but as the beam length (or lifting spread) increases, the stress reaches an inflection point where the allowable bending stress starts to drop off. Crane and rigging performance evaluations may focus on crane and rigging usage, inspection, and worker skill levels and have the potential to reveal current status compared to recommended improvements. Use an Industrial Scale. ECONOMICAL LIFTING BEAMS Adjustable Spreader/Lifting Beam (ASLB16) Rated Cap. Below-the-hook lifting devices such as spreader bars and lifting beams must be designed in accordance with ASME BTH-1 and are to be manufactured and used in accordance with requirements of ASME B30.20 which specifies requirements for marking, inspection, construction and operation.

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. An Overview of ASME BTH-1 (spreader bars and lifting beams) When planning to design lifting beams (or any other below-the-hook lifting devices), there are many aspects that must be considered . I forgot my password. Fatigue design is not required for bars classified as service class 0 due to the low number of total load cycles, but as the number of load cycles is increased, the potential for fatigue failure increases. Our engineering team is capable of designing and constructing for a customers special needs. I have extended your XLC Pro subscription by six months by way of thanks. Spreader Beam Design Calculation Xls. The design of lifting beams must meet specific calculation requirements per BTH-1 to verify that the design will be safe and effective for its intended below-the-hook lifting application. Along with stress, buckling is also a critical factor in lifting beams that must be addressed in detail to ensure that the structure can handling the loads imposed on it.
