Wireless Anti-two Block

Wireless A2BHirschmann's wireless anti-two block switch assists in reducing equipment damage by preventing the hook block from contacting the boom tip on cranes and other lifting equipment. 

The electrical switch element is completely sealed in the housing.  The housing is made of a corrosion-proof, light metal alloy and is treated and coated making it resistant to the damaging affects of the environment.  Depending on the type, one or two sectional resistors allow monitoring the feed line.
