Crane Limit Switch Rotary Gear Limit
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.
Function: Limit Switch is to stop the mechanism of drive at the extreme clock wise/anti clock wise position. These rotary limit switches are particularly suited for use on reversing drives such as electric hoists, winches, overhead cranes and traverse.
Application: Rotary geared type limit switches are suitable for use reversing drives such as hoists, winches, rolling mills and various other mechanisms used such used in steel plants such as coke oven and feeding machinery.
