Crane Limit Switches

Product Details:

Introduction:Lever 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 voltsA.C. 50 Hz and 10amps and 40 amps current rating.Function:The lever Limit switch operates when its lever reaches its pre-determined position andthe lever is moved over a projecting member fixed on the Girder.The Limit Switch contacts are automatically reset when the lever returns to zero positiondue to spring action.

Product Details:

Crane 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, over head 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.

Product Details:

Embicon is the leading manufacturer & exporter of Hoist Gear Limit switches.Hoist Gear Limit switches has been designed and manufactured according to safety standard are suitable for use on reversing drives such as hoists, cranes, winches and rolling mills etc.

Design:

• The driving motion is transmitted by worm gear. All gears and hubs are made of low wear thermoplastic. The rotational movements are transmitted to switches by adjustable cams.

Driving cams:

• Each lever has a single micrometric resister screw.This screw exclusively works on its own combined lever, excluding any mechanical contact with any other next to it. The regulation is easily made by use of screwdriver on a register screw. The special friction system assures a rapid and precise adjustment.

Product Details:

Weight Operated Limit Switches are used on control / power circuit of reversing drives so as to limit their rotation / movement within a predetermined position. When the snatch block of the crane reaches its top position the snatch block pushes a plate which is hanging from one end of the lever of the limit switch.

Product Details:

Counter weight Limit Switches are used for Heavy duty E.O.T. Cranes, Hoists to prevent over travel of hoisting motion on power and control circuit up to 500 V and 40 Amps. continuous current. The limit switch normally remains closed and cuts off power to stop the motor of the crane.
