THE HARDEST WORKING SHACKLES IN THE INDUSTRY Many times over the years, we have been asked if CM rigging products are as good as, the same as, or equal to the competition. Through all of this, we felt that it was time to put our responses down on paper so they can be made available to channel partners, end-users, our sales force and anyone who may eld those questions. At Columbus McKinnon, we are condent that our products are of the highest quality on the market today and strive to continue improving them. So, our response to those questions would be that we are not only as good as the...

The Charpy V-Notch Test was developed during World War 2 to test the penetration resistance of steel armor. It has since evolved into a method to test for toughness of steel in critical structures such as buildings or bridges. In this test, a bar is mounted horizontally with the notch facing away from an impact weight suspended on a pendulum. When the weight is released, it swings down and breaks through the bar. An indicator measures how far the pendulum continues to swing after breaking the bar. The momentum of the pendulum then is the measure of the resistance of the material to breaking...
