The iSENS HES anti-two block switch assists in preventing equipment damage due to the hook block 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 enable the feed line to be monitored.
