Consider these 5 key points prior to acquiring a accuracy lift table for your assimilation project.
Determine the amount of deflection that serves for your application. Accuracy lift tables can have repeatability in altitude that is just as good as +/ -.025″ of an inch. Remember, the much more accurate the lift needs to be, the extra costly it is going to cost you.
2. Allowable Lots Drift:
If your application needs zero tons drift, then you a accuracy sphere screw lift table could be your best option. These Electro-mechanical lifts are powered by an electric motor which turns a screw which in turn raises and lowers the lift. They are really exact and likewise have absolutely no load drift. This device is excellent for applications that need to have security at any height as well as for long term periods of time.
3. Filling Conditions:
It will certainly be essential to understand just how the load is transferred onto and also off of the accuracy lift table. If your application calls for the lift to be loaded at a mid-stroke placement, (that is where the lift is not totally elevated, or fully decreased) then you need to be clear with the maker on how that load is put onto the lift. For example, if the lots is rolled onto the lift, this can present significant offset loading issues for the precision lift table. If the load is reduced onto the lift, after that there is much less of a possibility for deflection and also damages to the lift.
The method in 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 rather than a human operator, Nevertheless, if an driver is responsible for cycling the lift, then the device will likely need to be equipped with a vertical string encoder or restriction buttons. The vertical string encoder will keep the PLC informed on what elevation the lift is presently at. This allows it to stop at fixed heights as required by the application. The limit switches work in much the same manner, but with much less flexibility.
5. Duty Cycle:
Precision lift tables are commonly high responsibility cycle lift tables as the majority of automation does not include the human operator. Hence, the lifter has to perform its cycling at an increased rate as its outcome is a lot greater than a standard lift. Duty biking can be as high as 120 times an hr based upon the application needs as well as the product that is being produced. If this is a measure of your application, then this will certainly require the precision lift table to be enhanced at the scissor joints, the scissor tracks, as well as also the roller wheels.
