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 beyond finding materials that meets a few basic engineering calculations. Most erectors and riggers accumulate an assortment of lifting beams during the course of time. One type of lifting device that is common in construction and that is not specifically addressed in the standard is the stiffened plate lifting beam.

The equations commonly used in practice for the design of beams are based on the assumption that the members are restrained against lateral displacement and twist at the ends of the unbraced length. RICKER Lifting beams also known as spreader beams are used to underside for attachment to the object to be hoisted thus assist in the hoisting process. We can see that it has a lifting eye at its top in the middle while the eyes below are used to connect the slings to the lifted object.

A lifting beam is a solid or fabricated m etal beam suspended from a hoistcrane or from forks of a forklift designed to pro vide multiple lifting points. The following paper has numerious examples. A lifting beam has a simple design consisting of a beam with a single attachment point centered on the top side of the beam for connecting to a crane hoist or other lifting machine.

I am currently making a spreadsheet to determine the capacity of lifting lugs using the processes laid out by David T. There are other factors that need to be addressed.

Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore. Determine the normal capacity of a beam and divide the load by 2 to get the factor of safety of 5 A36 material. There are two basic approaches to this.

Ad Shop A Wide Selection Of Material Handling Equipment To Easily Move Lift More. ADesign and Construction of Lifting Beams - David T. 28 Nov 18 1836.

Design and Construction of Lifting Beams DAVID T. Spreaders can be made in modules which are assembled into the configuration required. This is also in line with the load ratings for other components of the lifting assembly such as slings shackles etc.

In this article we will explore the design of a basic spreader beam and see what design checks are needed to establish the suitability of a spreader beam for particular lifting operation. Ricker originally published in American Institute of Steel Construction AISC - Design Journal 4th Quarter 1991. Some common profiles are shown in Fig.

Lifting beams also known as spreader beams are used to assist in the hoisting process. Design and Construction of Lifting Beams. Design issues that are applicable to this type.

Design and Construction of Lifting Beams. Lifting beams can have adjustable lifting points which can be moved along the beam to suit the particular load. This standard defines allowable stress structural design requirements for lifting devices used in construction and general industry in conjunction with cranes derricks and other.

Lifting beams convert lifting loads into bending forces on the beam. Tension Failure at the sides of the holes 2. Most erectors and riggers providing a large range of adjustment.

Most erectors and riggers accumulate an assortment of lifting beams during the course of time. Designing a spreader beam for lifting. Thus the buckling behavior of suspended beams can.

Design and Construction of Lifting Beams Engineering Journal American Institute of Steel Construction Vol. 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. Lifting beams also known as spreader beams are used to assist in the hoisting process.

If we resolve the forces we can immediately see that the lifting beam will be primarily under bending stress see figure 2. Lifting beams are designed to take bending loads. The right choices can help to reduce conflict in the design and construction process and to reduce the likelihood of expensive remedial work.
