Lifting Spreader Beam Design

Lifting spreader beam design.

If we resolve the forces on the whole beam we get the force diagram as above. The range of designs and capacities is therefore only limited by practicality. A spreader beam is designed to take primarily compressive loads as can be seen in the figure above. 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. Spreader beam vs lifting beam at the outset it is important to clarify the difference between a spreader and 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.

We manufacture the world s best plate clamps and other lifting equipment as well as material stands. 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. Spreader bars are the best choice for loads where the lift points are far apart and load control is important. 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.

Machining welding or m w is a leader in innovative design for lifting products. Spreader beams designed to direct load to top rigging and hooks requires a greater amount of headroom than a lifting beam. 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. Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process.

Lifting beams frames and spreaders are usually designed and built for a specific purpose. 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. Custom design and off the shelf options available.
