When it comes to building, construction and other industries that rely on props of any kind, finding quality, well-made products is a must. While there are a number of cheaper options on the market, these should be avoided since they may put your project, as well as your life, in jeopardy. Some of the primary ways you can feel confident you have found a quality acrow prop are highlighted here.
Inspect the Collars
The collar of an acrow prop should never break apart under a load. Collars should be soft, which means when they become overloaded the pin will just sink into the collar, allowing the prop to stay in place and support the structure it is holding. There are a number of props that come with brittle collars which break into pieces when loaded, which can be extremely dangerous. By looking at the collars prior to purchase, you will be able to have peace of mind you have found a quality option.
Look at the Inner Tube
Most inner tubes used by acrow props are made from high tensile prime steel. This is done for a reason. It allows the inner tube of the acrow prop to bend and then recover if being used at high extensions. If the inner tube is not made of this material the entire prop will bend and continue bending until it finally collapses.
Another sign of quality inner tube is if when the prop is fully loaded, the hole for the pin does not elongate. This means it is secure and will not fall or become damaged. If the hole does elongate then the prop may fail, causing damage and injury.
Check Out the Outer Tubes
The outer tube is typically constructed from a single piece and does not have any weld beneath the thread. This is all good until you find out the thickness of the tube is the same as the lower portion of the welded acrow prop outer tube. If this type of product is purchased, the thread will not be strong enough, and the total load rate may be reduced.
These are three methods you can use to find quality, high-grade acrow props. While the price may be a bit higher initially, investing this extra money will pay off in terms of safety and longevity. It is smart to find a reputable seller that is known for quality parts. This will maximize the ability of the acrow props you use.
