UNIQUE PROTECTION SYSTEM FOR WIRE ROPE ELECTRIC HOIST
Wire rope electric hoist also has its own unique protection system, it is because of this protection system, in order to make the wire rope electric hoist to maintain normal operation, in order to ensure the safety of their own operators.The following author according to many years of experience in the industry, talk about the wire rope electric hoist unique protection system, for the vast number of new and old customers and enthusiastic users to learn reference.
1. The voltage loss protection circuit structure has the function of voltage loss protection. When the power is restored after power failure, the starting button must be pressed again before the crane can start again, which eliminates the possibility of the crane running on power.
2. The earthing protection on the crane metal institutions and all electrical equipment metal shell, tube slot, the low voltage side of transformer are equipped with reliable grounding, electric hoist to grounding resistance Ω 0.1 or less.
3 short circuit protection wire rope electric hoist short circuit, the main circuit breaker will automatically trip, play a protective role.
4 overload protection wire rope electric hoist once overload, wire rope electric hoist will immediately trip protection.
5. Lifting limit protection wire rope electric hoist when lifting to a limited position, the power will be automatically cut off for equipment protection.
