Has your risk assessment identified the risk of industrial doors falling during use? A failure in the door's primary operating system could result in an uncontrolled drop, thereby risking severe damage to any equipment or, more critically, people below. The older the door, the higher the risk. A large number of our customers have used Guard load arrestors as a cost effective, easy way of managing this risk, avoiding the expense in replacing the entire door / lifting mechanism. Simply install one (or more) load arrestors above the door, and attach the end of the Guard's cable to door itself. Should the door fall, the Guard will catch the falling door, preventing potentially catastrophic damage.

Guard load arrestors are ideal for this type of application, because the cable automatically extends and retracts, following the movement of the industrial doors.

One important consideration, when utilising Guard's is this way, is the activation speed of the Guard. If the door lowers at a faster rate than the Guard's activation speed (0.6m per second), then the load arrestor would activate when not needed, which would be problematic. Therefore, make sure you carefully establish the door's operating speed beforehand.
