Weight Operated Limit Switches are used on control / power circuit of reversing drives so as to limit their rotation / movement within a predetermined position. Operation:
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. Due to the weight placed on the other end of the lever this lever is pushed up. When the lever is pushed up the shaft to which this lever is connected rotates there by rotating the cams which eventually open the contacts and disconnect the motor. The electronic limit switch contacts are automatically reset when the lever returns to zero position due to gravitational force

With our decade of experience, we are catering to the varied requirements of our clients by introducing quality array of Limit Switch that is made of the superior quality raw material that is being sourced from certified vendors of the industry. Apart from this, terminals are used in the switch that prevents short circuits. Moreover, this switch is checked by our professionals during production process.

Rotary Geared Limit Switch GRLS is used to trip motor supply when the moving load reaches the extreme end positions of working zone. The driving motion is transmitted by worm gear through worm shaft. The rotations and movements are transmitted to switches by adjustable cams.

The Rotary Geared Limit Switch is a precision-engineered mechanical device used to control the movement limits of industrial machinery by converting rotary motion into electrical switching signals. It is commonly used in lifting equipment such as cranes, hoists, and winches to stop motion at pre-set positions, ensuring safe and accurate operation.

Lever limit switch its use in EOT crane.
1NO 1NC Contacts. Preventing accidential over travel of crane. Once it touch lever of switch its automatically stops.

The GRLS FG 50 is a small rotary switch with a range of ratios, including 12.5, 25, 50, and 1001. It is a limit switch that is used to trip the motor supply when the moving loads reach the extreme end positions of the working zone

Operates the control change-over the contacts of a motor of a moving equipment when a cam moving with loads actuates the lever / (or the weight rests on a surface) of the Limit Switch. This turns the cam on a square shaft and operates the NO / NC change over the contact elements.
