Extendamatic 2-Hand Anti-Pinch Control

From time to time we've had safety engineers express concern over the possibility that the Extendamatic gate in itself represented a pinch hazard. We have resolved this issue by adding a two-hand anti-pinch control to the gate and it is now standard equipment on the product.

The mechanism itself is a steel blocking device with a ball-handle attached to it that drops into position by gravity when the gate is extended. It is important to note that any purported pinch hazard only exists during the last few inches of the retraction sequence. That's when the control kicks in.

Here's how it works. When the openings in the links diminish to a distance of 2-3/4-inches during the retraction process the gate locks up. It cannot be fully retracted unless the operator manually disengages the control by placing his left hand on the ball handle in order to deactivate the lockup. At this point in the closure sequence, the operator has his left hand on the ball handle of the anti-pinch control and his right hand on the ball handle at the other end of the gate. Both ball handles are located at a comfortable to operate safe distance above the gate mechanism where it is not possible to put your fingers into harm's way. At the same time, the operator's body position creates a block that keeps any third party onlookers at bay.

We have never considered Extendamatic to be a pinch hazard and this is borne out by a 15-year+ record of operation with no occurrence of operator injury. Some of America's largest companies rely on Extendamatic to keep their employees from dangerous machines, while at the same time providing them with the total access they need to load and service those machines when required.
