Lifeline 4 and Rotacam
|
Description
Pneumatic Rotacam
Based on the highly successful conventional Rotacam, the Pneumatic Rotacam has the same design features except that it gives positive acting isolation of a machine's compressed air supply instead of an electrical power source.
The switch is mounted at the hinge point of the guard door. The bored stainless steel operating shaft is mounted in a sealed bearing which is so robust that it enables the switch itself to be used as the hinge pin if necessary.
The pneumatic valve specifications are shown below. The external switch dimensions and operating shaft specifications are the same as the conventional Rotacam.
Note: The Pneumatic Rotacam does not have the adjustable cam used with the standard Rotacam.
Pneumatic Lifeline 4
Based on the conventional Lifeline 4 this rope operated pneumatic safety switch can be used for guarding exposed pneumatic machinery and conveyor equipment.
The Pneumatic Lifeline 4 is immune to machine vibration thus overcoming the problem of nuisance tripping.
The pneumatic valve specifications are shown below. The external switch dimensions are the same as the conventional Lifeline 4.
