Real-time monitoring of traveling block height, hook weight and other data to prevent block from crown collision, floor crash, overweight, etc., with reliable danger warning, emergency braking, deceleration and overweight protection functions.
Main functions：
1. Real-time monitoring: The LCD screen of the main control box displays the position of the traveling block, the weight of the hook and the direction of movement in real time.
2. Double-limit alarm: support independent setting of upper alarm (crown saver) and lower alarm (floor saver), and the alarm value is adjustable.
3. Position brake: automatically output the brake signal when reaching the set position of upper collision or lower collision height, and the linkage draw-work will brake and stop.
4. Hook weight overweight brake: Hook weight overweight alarm and brake value can be set to realize double protection.
5. Data record: alarm events and data records are automatically stored, and historical records can be queried.
6. U disk export: alarm events and data records support U disk export.
