Take into consideration these 5 key points before purchasing a precision lift table for your combination project.
Identify the quantity of deflection that is acceptable for your application. Precision lift tables can have repeatability in elevation that is like +/ -.025″ of an inch. Bear in mind, the extra precise the lift needs to be, the much more expensive it is mosting likely to cost you.
2. Allowable Lots 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 electrical motor which transforms a screw which consequently raises as well as lowers the lift. They are extremely exact and additionally have zero tons drift. This device is excellent for applications that need to have stability at any elevation as well as for extended amount of times.
3. Packing Conditions:
It will be important to understand exactly how the tons is transferred onto and off of the precision lift table. If your application needs the lift to be loaded at a mid-stroke placement, (that is where the lift is not fully raised, or totally decreased) then you need to be clear with the producer on exactly how that tons is positioned onto the lift. For instance, if the tons is rolled onto the lift, this might offer major balanced out loading problems for the accuracy lift table. If the lots is lowered onto the lift, then there is less of a opportunity for deflection and damages to the lift.
The technique in exactly how the precision lift will certainly be regulated needs to be discussed early in your drawing board. Many automated lifts are controlled with a PLC rather than a human driver, However, if an driver is in charge of cycling the lift, after that the device will likely have to be equipped with a upright string encoder or limitation buttons. The vertical string encoder will keep the PLC informed on what elevation the lift is presently at. This enables it to quit at established elevations as required by the application. The limit switches work in much the same manner, but with much less versatility.
5. Responsibility Cycle:
Accuracy lift tables are frequently high obligation cycle lift tables as most automation does not involve the human operator. Therefore, the lifter must do its cycling at an accelerated rate as its result is much more than a conventional lift. Duty cycling can be as high as 120 times an hr based upon the application requirements as well as the material that is being produced. 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, as well as additionally the roller wheels.
