Lifting Spreader Beam Design

Custom design and off the shelf options available.

Lifting spreader beam design. Lifting beams frames and spreaders are usually designed and built for a specific purpose. Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process. Spreader bars are the best choice for loads where the lift points are far apart and load control is important. Spreader beam vs lifting beam at the outset it is important to clarify the difference between a spreader and a lifting beam.

Ce marked and certified to all global industry standards. 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. Our lifting products and plate clamps provide years of reliable service and are rigorously tested so you can get your work done safely and on time. It is important to take care in selecting the right type of beam to be used and to plan the lift taking the following into account.

We manufacture the world s best plate clamps and other lifting equipment as well as material stands. Asme b30 20 bth 1. A lifting beam is under pressure at the single lifting point and therefore subject to shear and bending while a spreader beam is designed to work under compression and spread the load out evenly over a. Machining welding or m w is a leader in innovative design for lifting products.

Lifting beam design 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 range of designs and capacities is therefore only limited by practicality. Custom lifting devices like spreader bars are always in compression and are designed with varying pipe diameters and thicknesses to obtain the proper design factor to meet the maximum rated capacity. If we resolve the forces on the whole beam we get the force diagram as above.

Design of adjustable spreader lifting beam of standard profile heb series geometry of lifting at the each end of the hollow pipe spreader beam solved using the equations of static equillibrium a strength design design for flexural bending stress selecting the section initially based on this. Spreader beams designed to direct load to top rigging and hooks requires a greater amount of headroom than a lifting beam. A spreader beam is designed to take primarily compressive loads as can be seen in the figure above.
