Machine guarding is the physical barrier between a person and a moving machine. What is on this page goes around presses, conveyors, robotic cells and anything else with a pinch point, a rotating part or a stroke someone can reach into.
The systems here come in a few forms. All-welded steel guards are one fixed piece, built for a spot where the guard goes in and stays. Modular and adjustable perimeter systems build a fence line out of panels and posts, so you can size an enclosure to the machine and change it later. Lift-off and lift-out systems use panels that come out by hand when maintenance needs to get behind them, instead of unbolting the whole run. Welded wire panels enclose a robotic cell while keeping sightlines into it.
High profile and low profile machinery guards cover the two common heights, either a full standing barrier around the equipment or a lower guard where an operator still works over the top of it. Foot guards, wheel guards and toe guards are the small end of the same idea, mounted low on powered trucks and mobile equipment to keep feet clear of the wheels.
