Generally, a 6.5-knot trolling speed is ideal for pulling spreader bars, but if seas are glassy flat, you may want to bump it up to 7.5 or 8 knots. “When conditions are ultra clear and calm, you want to move the bars a lot faster to be able to trick tuna,” Angelini says.8 Apr 2020
How wide should a spreader bar be?
Generally the mediums, get 10", large & xl the 12" and small and xs get the 6". There have been instances of folk who want more slide from side to side getting the smaller size, but in general, having the pull either side of you hip bones is better than a point load in front.5 Jul 2005
What is the point 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.28 Jun 2021

Is a spreader bar hammock better?
There are a lot of benefits of spreader bar hammocks, as they are easier to get into, and tend to dry faster than non-spreader bar hammocks as the fabric is pulled tightly. Also, hammocks without spreader bars tend to be more comfortable, as they have more sag, and allow you to be cocooned by the fabric.16 Sept 2019
What are spreader beams used for?
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.2 Oct 2017
What is the difference between lifting beam and spreader bar?
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.11 Oct 2018
What is a spreader bar on a hoist?
What are spreader bars? Spreader bars connect to the tape of the hoist unit and provide a stable structure to hang a sling from. This gives a more balanced and supportive lift to the user. Understandably, spreader bars need to cater to a lot of different users and a lot of different slings.5 Apr 2018
Why do we use spreader beam?
Spreader beams are ideal for lifting very wide or heavy-duty loads. Spreader beams also help to control the load and when rigged properly, can reduce the chances of: Load tipping, sliding, or bending. Crushing or damage to the load because you can control the sling angles.2 Oct 2017
Why do I need 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 a spreader bar in lifting?
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. The spreader bar is lighter, more compact, and less expensive than a lifting beam, and designed for the weight to be distributed equally across the length of the bar.18 Sept 2020
