Located around the perimeter of or near the danger area. Operator must be able to reach to stop the machine.
By opening the guards, tripping mechanism can be activated automatically
Itself actuated by the movement of the dangerous part and ensures that the operator is prevented from coming into contact with dangerous parts
What is Safety Devices [Trip Wire Cables, Kick Plate etc.]
Simple barrier, make it physically difficult to access to point of operation
Located around the perimeter of or near the danger area. Operator must be able to reach to stop the machine.
By opening the guards, tripping mechanism can be activated automatically
Itself actuated by the movement of the dangerous part and ensures that the operator is prevented from coming into contact with dangerous parts
What is Gates/Interlocked Guards?

Located around the perimeter of or near the danger area. Operator must be able to reach to stop the machine.
By opening the guards, tripping mechanism can be activated automatically
Itself actuated by the movement of the dangerous part and ensures that the operator is prevented from coming into contact with dangerous parts
What is Presence Sensing / Automatic Guards?
Simple barrier, make it physically difficult to access to point of operation
Located around the perimeter of or near the danger area. Operator must be able to reach to stop the machine.
By opening the guards, tripping mechanism can be activated automatically
Itself actuated by the movement of the dangerous part and ensures that the operator is prevented from coming into contact with dangerous parts
What is Pressure Detection Mat?
Commonly known as a safety mat or mat switch. When any one stands on the mat, safety of machine activates and machine stops
