How wide should a spreader bar be?

The spreader bar has three easily adjustable width positions: 100”, 105” and 110”, and a load rating to 20 tons (40,000 lbs) for 40- to 60-degree inclination angles and to 15 tons (30,000 lbs) for 30- to 40-degree inclination angles.

What is a steel spreader beam?

The term ‘Spreader Beam’ refers to a beam used to spread apart two slings and loaded in compression.

Can you add a spreader bar to a hammock?

Replacement spreader bars are now available in four sizes to fit our Single (48″), Large (55″), Deluxe (60″) and Presidential (65″) rope hammocks. If both of your spreader bars need replacing make sure to change the quantity to (2).

What are the major forces on spreader bars and lift beams?

Spreader beams convert lifting loads into compressive forces in the beam and tensile forces in the slings. 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.

What is the difference between lifting beam and spreader beam?

The main difference between the two types of lifting devices is the types of forces that are applied to the beam. Lifting beam – Any beam where the load being lifted puts a bending stress in the beam. Spreader beam – Any beam where the load being lifted mainly puts a compressive stress in the beam.

What is a spreader beam?

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.

How do you make a lifting beam?

In designing a lifting beam the maximum desired lifting capacity must be established and also the governing geometry, that is, the maximum length and the spacing of the top and bottom lugs. Any beam depth limitations should be considered. The line angle should be established (angle in Fig. 2B, for example).

What is the purpose of a spreader bar?

A spreader bar allows the user to attach the load at two points. This evenly spreads the load throughout the bar and wire rope slings and make it easier to lift. Moreover, the attachment points are positioned so that the bars seamlessly allow vertical hoists.
