Reliable position detection for chain hoists
You often cannot fall back on computer-controlled systems. Because these cannot be built into chain hoists or the systems are operated in environments for which these computer controls are too sensitive.
Gear limit switch as a solution for position detection on chain hoists
Gear limit switches are used in applications that need to work without additional help from external computers. For example, when a certain position is reached or when the chain hoist has to be switched on or off reliably. They work purely mechanically and turn the internal switches on or off via a cam mechanism. A gear designed for the special case ensures individual adaptation.
If safety aspects also have to be taken into account, switches with positive opening are used, which always safely separate the electrical connection even in the event of an overload and the associated merging of the electrical contacts.
If position settings need to be changed frequently, it is important that these changes can be made easily, yet reliably. Adjustment options are suitable here, which allow the switching position to be set without much effort by simply turning the cams on the axle.
If detailed information about the current position is required, the gear limit switches can also be equipped with resolvers or encoders. These then provide millimeter-precise information about the position of the object to be lifted.
Conclusion:
Geared limit switches are robust and reliable solutions for triggering switch confirmations at preset positions on chain hoists. With their precision and functionality that does not require computer control, they are suitable for reliable use in any environment.
