MATERIAL MC Rope Safety Lock Switch from the United States

Model PC is a sturdy and compact safety switch that can quickly and actively turn off hazardous equipment in emergency situations or during normal operation. Start by pulling the cable by hazardous operators. The output contacts of Model PC can control two independent circuits, one for machine shutdown and one for alarm.

working principle

When an emergency occurs at the tape transportation site, the steel wire rope tied to the lifting ear of the rope switch can be pulled to control the internal micro switch action of the slider inside the machine, and issue a shutdown or alarm signal

The automatic reset model automatically resets after releasing the wire rope, while the manual reset model requires operating the reset handle before resetting.

For bidirectional operation, steel wire ropes can be installed on both sides of the switch. In the event of an accident on the conveyor belt,

Pulling the steel wire ropes on both sides to achieve emergency shutdown can timely and effectively avoid the expansion of accidents, protect personnel or equipment safety, and ensure safe production.

Installation precautions

Select reasonable installation spacing and configure steel wire ropes with appropriate thickness based on product characteristics,

The bracket of the steel wire rope should be as smooth as possible, and the spacing between brackets should not be too long (the spacing between brackets should generally be selected between 2-3m).

In practical engineering, try to control it at around 30m to avoid excessive pulling rope due to heavy weight and resistance, which may affect operation and switch reset;

The thicker the rope, the better (usually the diameter of the steel wire rope does not need to and should not exceed 5mm). It should be matched with the operating force of the switch action,

In fact, excessively thick and heavy steel wire ropes can cause switches to be in a semi active state, which is not only prone to misoperation, but also prone to damage to switch mechanism components.
