The gravity limit switch is used for heavy duty EOT Cranes and Hoist. This helps in evading extra travel of hoisting motion on power and control circuit up to around 500 V and 40 Amps. nonstop current. The gravity limit switch is also suitable for utilizing reversing drives such as winches, rolling mills and numerous other mechanisms used in steel plants, like for instance coke oven and feeding machinery.

At Vijaylaxmi Enterprises, our engineers manufacture the counter weight limit switch by means of cast iron or cast aluminium, in order to make sure that they hold robust design and operate for longer duration.

Most importantly, our offered range of counter weight limit switch is prepared keeping in mind the global standards. The counter weight limit switch is tested on numerous parameters of quality with the intention of delivering flawless product to our clientele. Our quality check team scrutinizes each counter weight limit switch so that the end user does not have to face any issues.

Counter Weight Limit Switch: Know how it works:

At the mid of the lever, a shaft is there with connected coaxial cams. The lever shaft and cams, all rotate at the same time, at the same angle.These cams are accountable for altering the state of electrical contacts location, placed within the limit switch enclosure. Electrical output wire is suckled to crane control panel. Then, the suspended weight is straight away linked to the hoist wire rope at the prearranged point where it stops the hoist from arriving at the upper block and rope drum.

Suspended weight is a slightly heavier in comparison to the counter weight. This is owing to gravity effect. The suspended weight wire turns out to be stiff and it lets counter weight lift upward. During usual operation, the limit switch generally stays closed. A gravity limit switch won’t possess a spring return mechanism.

The counter weight limit switch (gravity limit switch) operates when the hoist comes to its pre-established point. In this scenario, the suspended weight lies on the surface of the hoist or crane and suspended weight wire drops and counter weight alters the position and electrical contractor break off power to evade the hoist motor.

The counter weight switch can be utilized parallelly with rotary limit switch in a perpendicular type motion such as hoisting .

If the rotary limit switch isn’t unsuccessful to initiate at the correct number of turns, the gravity limit switch will be run to offer an emergency stop .

Features of Counter Weight Limit Switch:

1. The offer counter weight limit switch is highly known for its strong design
2. They possess rust resistance attributes
3. The limit switches are easy in terms of installation
4. They have reliable operation

At Vijaylaxmi Enterprises, customers can avail these counter weight limit switches at reasonable cost.

Rotary geared limit switch is suitable for use on reversing drives such as hoists, winches, rolling mills as well as numerous other mechanisms utilized in steel plants such as coke oven, feeding machinery etc. In short, reversing drive power control is accomplished with Rotary Limit Switch that confines the power flow. Rotary limit switch augments the safety of EOT cranes and heavy-duty mills by shortening the power supply once reaching a set frequency parameter. When it comes to reaching the limit by EOT Cranes, the crane will only be able to make movement in the differing direction therefore evading an accident.

Rotary Limit Switches Know how it works:

A rotary limit switch functions primely on the principle of a worm drive. It is interesting to learn that a worm drive mechanism is well-matched since the adequate rotation is generated to move the attached gears in the limit switch.

Rotary geared limit switch is utilized to regulate the movement of engineering machinery when it’s essential to assess movement depending on the spin angle and/or the count of shaft revolutions, offering upper, lower and/or transitional limits for stirring machinery and mechanisms.

A two (or more) contact elements are operated by respective rotating cams, suitably adjusted on a cam shaft which rotates with fixed speed ratio of the drive motor shaft. Each cam is fortified with a “micrometric” modifiable register screw which functions in a reliant way, so it is conceivable to attune the opening and closing of every microswitch as per the essential requirements.

The cams can be positioned in a stepless way so that they trip motor supply and stop the motion at the set point of travel. The contact points possess a holding strength of 500 Volts of A.C. for 40 amperes of continuous supply. Since we have acclaimed the position of one of the top rotary limit switch manufacturers in India, we make sure that our qualified team examine the contact points for precise cut off points.

Moreover, we ensure that the offered range of rotary geared limit switch is thoroughly checked and carefully scrutinized before being available in the market. Vijaylaxmi Enterprises endow rotary gear limit switch which come in standard ratios or direct ratio. They can be constituted and united with encoders and potentiometers to meet your individual requisites. Being one of the top rotary switch manufacturers in India, we are affianced in offering snap action switches and various cam type to meet customers’ requisites.
