Inside the switch are gears and a series of cams.
Rotary limit switch crane.
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.
A limit switch is a critical component of overhead crane safety.
I agree that my details and data for answering my inquiry will be collected and stored electronically.
Limit switches are electromechanical devices that regulate everything from household appliances to industrial machinery.
The rotary limit switch is used to control the movement of 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.
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.
Cross limit switch for slow down and stop in 2 directions.
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.
We stock an extensive range of crane parts and feature thousands of products in our online store including conductor bar festoon systems overhead crane controls power electronics vfd s saf lift load limiters position limit switches rotary limit switches hoist and radio controls cable carriers cable reels and slip rings.
These rotary limit switches are particularly suited for use on reversing drives such as electric hoists winches over head cranes and traverse.
I have taken note of the data protection declaration.
Limit switch is to stop the mechanism of drive at the extreme clock wise anti clock wise position.
If you would like the motor to stop after a set number of shaft rotations a rotary gear limit switch can be used.
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.
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.
For an overhead crane they provide solid established points of reference for maintaining efficiency reliability and safety standards.
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.
Springer controls offers rotary limit switches with input ratios from 1 1 to 8100 1.
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.
