Take into consideration these 5 bottom lines prior to buying a accuracy lift table for your integration job.
Identify the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in elevation that is like +/ -.025″ of an inch. Keep in mind, the more accurate the lift needs to be, the more costly it is mosting likely to cost you.
2. Allowable Load Drift:
If your application calls for absolutely no lots drift, then you a precision ball screw lift table could be your best alternative. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which in turn increases as well as reduces the lift. They are extremely accurate as well as additionally have absolutely no tons drift. This system is terrific for applications that require to have security at any kind of elevation and also for long term time periods.
3. Filling Problems:
It will be important to understand just how the load is transferred onto and off of the accuracy lift table. If your application requires the lift to be filled at a mid-stroke setting, (that is where the lift is not fully elevated, or completely reduced) after that you need to be clear with the producer on just how that tons is put onto the lift. As an example, if the tons is rolled onto the lift, this might present significant offset loading troubles for the precision lift table. If the tons is reduced onto the lift, then there is much less of a possibility for deflection as well as damages to the lift.
The technique in just how the accuracy lift will be regulated needs to be discussed early in your drawing board. A lot of automated lifts are managed with a PLC instead of a human driver, However, if an operator is responsible for cycling the lift, after that the unit will likely have to be equipped with a vertical string encoder or limitation switches. The vertical string encoder will maintain the PLC informed on what altitude the lift is currently at. This allows it to stop at predetermined heights as needed by the application. The limit switches over work in much the same way, however with much less flexibility.
5. Duty Cycle:
Precision lift tables are typically high responsibility cycle lift tables as the majority of automation does not entail the human operator. Thus, the lifter needs to execute its cycling at an increased rate as its result is much higher than a standard lift. Duty biking can be as high as 120 times an hour based on the application demands and also the product that is being created. If this is a measure of your application, then this will certainly need the precision lift table to be strengthened at the scissor joints, the scissor tracks, and additionally the roller wheels.
