Lifting Spreader Beam Design

Machining welding or m w is a leader in innovative design for lifting products.

Lifting spreader beam design.

A semi spreader lifting beam refers to a lifting beam with a 2 leg top sling connection. 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. It covers all aspects of the selection design manufacture verification testing repair modification storage inspection and safe use of lifting beams and spreader beams. Spreader bars can be made in a variety of lengths connection types capacities.

Britlift can design and supply your whole lifting system including associated rigging. 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. Custom design and off the shelf options available. Asme b30 20 bth 1.

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

How to design a spreader bar. A pair of connection points on top of the beam helps to minimise the bending forces within the section and as such a semi spreader will. 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. Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process.

Verification of spreader beams lifting beams and lifting frames. 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. We manufacture the world s best plate clamps and other lifting equipment as well as material stands. The table of contents next page lists the sections covered and contains links to each section.
