2. Ensure the safety of personnel and equipment
When the cage falls down accidentally due to overspeed, the cage can be stopped smoothly on the guide rail, and the control power supply can be cut off to ensure the safety of personnel and equipment.
3. collision limit block ensures that the hanging cage does not fall to the top when running, and does not hit the bottom when running down
The anti-collision limit block ensures that the cage runs to the upper and lower limits. If the limit switch continues to operate due to fault, the main power supply is immediately cut off to stop the cage, so as to ensure that the cage does not fall to the top when running up and does not hit the bottom when running down.
