Lifting Spreader Beam Design

Lifting beams lifting frames spreader beams experts in the design and manufacture of below the hook lifting equipment to the offshore manufacturing construction heavy transport and breakbulk industries.

Lifting spreader beam design.

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. We manufacture the world s best plate clamps and other lifting equipment as well as material stands. Ce marked and certified to all global industry standards. Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process.

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. 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. 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. We have long term employees who take pride in their work.

Spreader beams designed to direct load to top rigging and hooks requires a greater amount of headroom than a lifting beam. 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. Lifting beams frames and spreaders are usually designed and built for a specific purpose. Machining welding or m w is a leader in innovative design for lifting products.

If we resolve the forces on the whole beam we get the force diagram as above. Spreader bars are the best choice for loads where the lift points are far apart and load control is important. 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. A spreader beam is designed to take primarily compressive loads as can be seen in the figure above.

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. Asme b30 20 bth 1. Spreader beam vs lifting beam at the outset it is important to clarify the difference between a spreader and a lifting beam.
