Rotary Limit Switch Crane

The rotary limit switch is used to control the movement of industrial machinery.

Rotary limit switch crane.

For an overhead crane they provide solid established points of reference for maintaining efficiency reliability and safety standards. Limit switch is to stop the mechanism of drive at the extreme clock wise anti clock wise position. Its shaft can be connected to the motor and after a set number of revolutions the cams operate the switches thus starting the predetermined movement. The shaft on the switch is attached to a motor usually indirectly via sprockets or gears so the limit switch shaft turns as the motor turns.

Limit switches are electromechanical devices that regulate everything from household appliances to industrial machinery. Rotary gear type crane control equipments make limit switches are used on control power circuit of reversing drives so as to limit their rotation movement within a predetermined position. It operates as an auxiliary controller of electrical motors through a power interface such as a contactor or plc. Limit switches have practically limitless applications in regulating crane operation to prevent potential incidents.

Inside the switch are gears and a series of cams. Cross limit switch for slow down and stop in 2 directions. These rotary limit switches are particularly suited for use on reversing drives such as electric hoists winches over head cranes and traverse. The rotary limit switch is used to control the movement of industrial machinery.

They can be configured with up to 12 contacts for signaling and combined with other accessories like encoders and potentiometers to achieve your desired result. Its shaft can be connected to the motor and after a set number of revolutions the cams operate the switches thus starting the predetermined movement. I have taken note of the data protection declaration. If you would like the motor to stop after a set number of shaft rotations a rotary gear limit switch can be used.

Springer controls offers rotary limit switches with input ratios from 1 1 to 8100 1. A worm gear and a helical toothed gear combined with one or more pairs of straight toothed gears are used for the transmission of the movement from.

The function of the limit switch is to stop the mechanism of drive at the extreme clock wise anti clock wise position.

It operates as an auxiliary controller of electrical motors through a power interface such as a contactor or plc. Custom input ratios are available on request.
