Take into consideration these 5 bottom lines before buying a precision lift table for your integration task.
Determine the quantity of deflection that serves for your application. Accuracy lift tables can have repeatability in altitude that is as good as +/ -.025″ of an inch. Keep in mind, the much more accurate the lift has to be, the extra expensive it is going to cost you.
2. Permitted Load Drift:
If your application requires no load drift, after that you a precision round screw lift table may be your ideal choice. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which subsequently raises as well as reduces the lift. They are very precise and also have no lots drift. This system is terrific for applications that need to have stability at any height and for prolonged time periods.
3. Filling Conditions:
It will certainly be necessary to recognize how the tons is transferred onto and also off of the accuracy lift table. If your application requires the lift to be packed at a mid-stroke setting, (that is where the lift is not totally increased, or totally lowered) then you require to be clear with the producer on just how that tons is placed onto the lift. For instance, if the tons is rolled onto the lift, this could provide major countered loading troubles for the accuracy lift table. If the load is decreased onto the lift, then there is less of a possibility for deflection as well as damage to the lift.
The technique in just how the accuracy lift will certainly be managed needs to be discussed early in your planning stages. Most automated lifts are controlled with a PLC instead of a human driver, However, if an operator is responsible for cycling the lift, then the unit will likely need to be equipped with a vertical string encoder or limit buttons. The upright string encoder will certainly keep the PLC informed on what altitude the lift is currently at. This permits it to stop at fixed heights as called for by the application. The limit changes work in similar fashion, but with much less adaptability.
5. Responsibility Cycle:
Precision lift tables are frequently high duty cycle lift tables as many automation does not involve the human driver. Thus, the lifter needs to execute its biking at an accelerated rate as its outcome is a lot more than a conventional lift. Obligation cycling can be as high as 120 times an hour based upon the application needs and the product that is being produced. If this is indicative of your application, after that this will call for the precision lift table to be strengthened at the scissor joints, the scissor tracks, and additionally the roller wheels.
