lifting beam spreader bar design considerations

Cost and weight of the rigging are important considerations when planning a lift, and therefore the Modulift Modular Spreader Beam is an ideal solution compared to other types of Spreader Beams: The key Modulift design feature is the separate Drop Link that slots into the End Unit at each end of the Beam – this eliminates any bending being ...

Nov 29, 2010· I am trying to design a spreader beam in which will have 2 possible lifting points at the bottom of the beam (4 nos. lifting lugs). The outside lifting points will be spaced at 4,410mm c/c and the inside ones will be spaced at 2,350mm.

Jul 08, 2014· How to Design a Spreader Bar. Sparta's approach to optimizing the spreader bar design (otherwise known as lifting bar or lifting beam) is an iterative process. 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.

Aug 05, 2020· Aug 05, 2020· Spreader beams are universally applied gear which is widely used in various types of lifting operations, onshore and offshore. 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.

Jul 19, 2005· RE: Lifting Beam / Spreader Bar Design Considerations mrMikee (Structural) 13 Jul 05 22:02 I've been told that OSHA requires a 3 to 1 factor of safety to yield and a 5 to 1 factor of safety to ultimate, but I don't have any details with me now.

Design and Construction of Lifting Beams Author: Ricker the object from tilting excessively should the hook be slightly off-center of the balance point. Lifting Beam / Spreader Bar Design Considerations - I find myself designing a variety of in house lifting beams and spreader bars for lifting plates two lift

Jan 23, 2021· Jan 23, 2021· A spreader beam is the simplest configuration of the beam, which is used for two or more than two point lift and also a leveled lift. A spreader beam absorbs the compressive force to protect the load being lifted. It consists of lifting eyes which is attached to the spreader beam by means of welding. Its purpose is to connect the load to the ...

While both a lifting beam and a spreader bar is similar in that they create a connection point between the load and crane, there are differences that make one better than the other in specific instances. The main difference between a lifting beam and a spreader bar is the design which dictates the way the force is transmitted during the lift.

Mar 16, 2018· Spreader bars, lifting beams, and other below-the-hook lifting devices are classified based on the frequency and capacity of lifts that are required of the device. In the latest revision of BTH-1 (2017), there are three design categories, categories A, B and C, as well as five different services classes, service class 0 through 5.

Jan 01, 1993· Lifting beam – v – Lifting Spreader Lifting beams, Lifting frames and Lifting spreaders are a means of providing two or more lifting points from the hook of the lifting machine or crane spaced so as to match the position of the lifting points on the load. The difference lies in the way the forces are transmitted.

How to Design a Spreader Bar. Sparta's approach to optimizing the spreader bar design (otherwise known as lifting bar or lifting beam) is an iterative process. 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.

Oct 02, 2017· Spreader Beams vs. Lifting Beams: Definitions, Differences, and Design. While spreader beams and lifting beams are the most popular types of below-the-hook lifting devices, there is a lot of confusion about the differences between the …

Jan 28, 2018· Jan 28, 2018· The Lifting Beam: A lifting beam is a below the hook lifting device that performs the same function as a spreader. It consists of a body and a set of lugs just like a spreader bar but lifting beams generally have one lug on the top in the center and 2 or more lugs along the bottom.

Jul 31, 2019· Combination Beams – Combine design elements of spreader and lifting beams, which have a centred lifting point as well as lifting points on the ends of the top side of the beam. Specialised Pipe Lifting Spreader Bars - Can be made to suit pipe lifting equipment used in the pipeline and coal seam gas industries.

Lifting Beam & Spreader Bar Design: 6 Quickies for Rigging Engineers Lifting beams and spreader bars have become an integral part of complex crane, rigging, and lifting activities. In response, a large below-the-hook-lifting devices market has grown supporting projects with some exceptional solutions (see Modulift, Liftmax, Caldwell ...
