Product Description

Scope Of Application:

An electrical automatic protection switch for crane wire rope. The transmitter and a proper weight of the heavy hammer matching, using the upper and lower movement of the hook to achieve the purpose of preventing the wire rope from rolling, but also to achieve the purpose of lifting the hook in a certain height. Suitable for various tonnage of tire crane, car crane, rail crane. Compared with similar products, it has the characteristics of advanced dynamic protection technology, compact structure, flexible action, strong sealing and waterproof performance, long service life and convenient installation.

Function Characteristics:
 

1,No directional long-distance partition wall control function, which can achieve signal coverage within 50m radius, and can penetrate through 2~3 walls.

2,Timeout protection function: when working, it will automatically stop after about 18 seconds of sending, and the built-in power supply is turned off at the same time, waiting for the cycle to repeat next time. Long stop after no current output, to achieve the purpose of energy saving.

3,Strong anti-interference ability: one million groups have no heavy code identification technology to ensure that the equipment does not disturb each other.

4,The switch contact has the form of often open and often closed, which can achieve the purpose of multi-purpose.

5,Reliable performance, sensitive action, switch contact is made of precious metal material, reliable contact, long service life.

6,Base plate reinforcement can be selected for the transmitter part (suitable for heavy load hammer)

7,It can be configured as various working modes, such as one payment, one payment, and multiple payment, which apply to different working conditions.

Technical Specification:
 

1,Power supply voltage:
(1) Transmitter: 5~10.5VDC (6F22 alkaline battery power supply) No power backconnection
