TS249 brake shoe wear switch



Function: The TS249 brake shoe wear switch is mainly used to monitor the wear of the hoist winch brake shoe. When the brake shoes wear to a certain extent and reach the set critical value, the wear switch will trigger the corresponding signal to remind the operator to maintain and replace the brake shoes in a timely manner, in order to prevent safety issues such as brake failure caused by excessive wear of the brake shoes.

Working principle: It usually works based on mechanical triggering or proximity sensing principles. For example, when the brake shoe wears out and the triggering mechanism reaches a specific position, the contact state inside the switch will change, thereby outputting a signal.



Clearance detection of mining disc brake



Importance: The size of the brake clearance of the mining disc brake directly affects the performance and safety of the braking. If the brake clearance is too large, it will lead to insufficient braking force and longer braking distance; If the brake clearance is too small, it may cause abnormal friction between the brake shoe and the brake disc, affecting the service life and operational stability of the equipment.

test method

Manual inspection: Regularly measure the gap between the gates manually using tools such as feeler gauges. This method is simple and direct, but has low efficiency and cannot be continuously monitored in real time.

Automatic detection system: using sensors (such as displacement sensors, inductive sensors, etc.) to monitor real-time changes in the gap between the gates. The sensor converts the physical changes in the gap between the gates into electrical signals, which are transmitted to the control system for processing and display. When the gap between the gates exceeds the set range, the system can issue an alarm signal and even automatically take corresponding control measures, such as stopping the operation of the hoist.

Detection frequency: According to relevant safety regulations and equipment operating conditions, regular gap detection of the gate is required. During the initial operation of the equipment or after major maintenance, the detection frequency may be relatively high; During normal operation, testing can be conducted at regular intervals (such as daily, weekly, etc.).



It is crucial to ensure the normal operation of the brake shoe wear switch and accurate detection of the brake clearance during the operation of the mining hoist for the safe and stable operation of the entire lifting system.
