What is a spreader bar in construction?
A spreader bar, also called a spreader beam, is a simple bar that holds two slings apart and distributes the weight over two or more pick points. Two lugs on top of the bar are each attached at an angle with a chain or sling that is connected to the crane. They’re most often used for very wide or heavy loads.
What is the function of a spreader bar?
A spreader bar is a type of below-the-hook lifting device used to aid crane operators in picking up large and sometimes heavy loads. The idea behind a spreader bar is to simply distribute the load of a lift across more than one point, increasing stability and decreasing the loads applied during hoisting.
What is spreader beam definition?
A spreader beam is a simple device consisting of a long bar that holds two slings apart. It’s designed to convert lifting loads into pure compressive forces and also spread apart the legs of a sling.
When should a spreader bar be used?
A spreader bar is a tool you can use when doing the crane-assisted lifting, which works by taking the load below the hook. This is specifically used when lifting very heavy or large increments that need something to spread the loads to avoid accidents.
What is a load spreader?
Material used to distribute the weight of a load over a given area to avoid exceeding designed stress.
What is the difference between a spreader bar and a lifting beam?
As a broad distinction, in their purest forms: Spreader beams are mainly subject to compressive stress and are lifted using a two-legged sling at the top. Lifting beams are mainly subject to bending stresses and are lifted from a central lifting lug.
