What is required for belt slip detection devices in conveyors?

• A. Only for conveyors longer than 10 meters
• B. For all underground belt conveyors or those over 15m in closed spaces
• C. Only on outdoor belt conveyors
• D. No requirement for slip detection devices

Answer: (B)

Belt slip detection devices are crucial for ensuring the safe and efficient operation of conveyor systems, particularly in underground mining environments. These devices are specifically required for all underground belt conveyors or those longer than 15 meters in enclosed spaces due to the potential hazards associated with a belt slip.

The importance of this requirement lies in the need to prevent equipment damage, material spillage, and possible safety incidents related to moving parts. In underground operations, where the environment can be less accessible and visibility may be poor, monitoring the status of the conveyor belt becomes essential. Detecting slip allows for immediate corrective actions to be taken, thus minimizing risks and enhancing operational continuity.

In contrast, the other options specify limitations that do not accurately reflect the regulatory requirements for belt slip detection. The requirement is intended to ensure comprehensive safety measures rather than being restricted by distance or location alone.
