The purpose of a pull cord installed along the belt line is to stop the belt in case of an emergency. This safety feature is crucial in mining operations where the conveyor belts transport materials and are often in environments that pose various risks. The pull cord is positioned along the length of the conveyor belt to ensure that workers can quickly access it from multiple points along the belt. If an incident occurs, such as a worker getting caught or equipment malfunctioning, pulling the cord immediately shuts down the conveyor, minimizing the risk of injury and allowing for quick response to the situation.

The ability to quickly halt operations through the pull cord mechanism is a vital safety measure in the mining industry, ensuring that workers can work with a greater sense of security knowing that they can easily stop the belt if necessary. This function is particularly valuable in preventing accidents and safeguarding health in potentially hazardous mining environments.
