Why & When you need a Load Arrestor
Material load arrestors are redundant braking systems to the lifting apparatus. They are designed to prevent the lifted item from falling in the event of a failure in any part of a primary-lifting device. Load arrestors prevent damage to tools, equipment and products. Most importantly, load arrestors prevent employee injuries and fatalities.
Hoosier Crane is an advocate of load arrestors. We have designed, tested and installed systems in many manufacturing facilities and have seen them work time and time again.
We install two types of load arrestors. The simpler unit is a self-contained wire rope or synthetic web material reel with a spring driven realer and a speed-sensing device. It works like the seat belt in your vehicle. These units are typically used in capacities up to 500 pounds.
The second type is used for higher capacity loads up to 6,600 pounds. These load arrestors utilize an over speed device: a wire rope is attached at the top and a special type of speed-sensing/load-arresting device is attached to the item being lifted. A Blocstop Overspeed measures the speed of the wire rope as it passes through the load arrestor. Any speed over a pre-determined value will engage the load arrestor.
If a load arrestor engages once and prevents damage to equipment and products, the savings will pay for load arrestors for all your equipment. We can’t begin to calculate the value of protecting an employee from a falling load, but we are certain that it is more than the cost of a few load arrestors. If you are building a material lift, work platform or any of the other uses we have outlined in this article and have questions about load arrestors please contact us.
