What are the 'Three No-Operate' principles in winch operation?

[Caden]

The 'Three No-Operate' principles are: do not operate when signals are unclear; do not operate without clearly seeing the upper and lower hooks; do not operate when the startup status is abnormal. Additional information is as follows: 1. Five points to note: pay attention to whether the indicators such as the voltmeter and ammeter are normal; pay attention to whether the brake is reliable; pay attention to whether the depth indicator is accurate; pay attention to whether the wire rope is neatly arranged and whether the force on the wire rope of the friction winch is consistent; pay attention to whether the lubrication system is normal. 2. Two musts: hands must not leave the operating handle; maintain a proper sitting posture, stay focused, and do not replace the driver while the winch is running. 3. Three observations: observe the signal, running direction, and the arrangement of the rope on the drum during startup to ensure accurate and smooth startup; observe the instruments and depth indicator during operation to ensure fast operation; observe the depth indicator and rope marks when stopping to ensure accurate stopping and one-time positioning.
