EOT Crane Limit Switches

EOT Crane Limit Switches 

Rotary Gear Limit Switch is basically consists of heavy duty worm gear drive. The worm gear unit is built in a cast housing fitted on main body of Limit Switch. The cam shaft which extends from behind the gear in to housing, accommodates the cams adjustable actuators which are fitted on the cams. These actuators strikes the contact finger of respective contacts.

Weight Operated Limit Switches are used on control / power circuit of reversing drives so as to limit their rotation / movement within a predetermined position.

Lever Type Limit Switch is used for heavy duty E.O.T. Cranes, Wagon shunting devices etc., to prevent over traveling or over traversing on power and control circuit up to 500 volts A.C. 50 Hz and 10amps and 40 amps current rating.

Gravity Limit Switches are used on Control / Power circuit of reversing drives so as to limit their rotation / movement within a predetermined position.
