Think about these 5 key points before buying a precision lift table for your integration project.
Identify the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in altitude that is just as good as +/ -.025″ of an inch. Bear in mind, the much more exact the lift needs to be, the extra expensive it is mosting likely to cost you.
2. Allowable Tons Drift:
If your application needs absolutely no tons drift, then you a precision ball screw lift table might be your best choice. These Electro-mechanical lifts are powered by an electrical motor which turns a screw which consequently raises and also lowers the lift. They are extremely specific as well as additionally have zero lots drift. This device is fantastic for applications that require to have stability at any height and for extended amount of times.
3. Filling Problems:
It will certainly be important to recognize just how the lots is moved onto and also off of the precision lift table. If your application calls for the lift to be packed at a mid-stroke placement, (that is where the lift is not totally elevated, or completely lowered) after that you require to be clear with the supplier on exactly how that tons is placed onto the lift. As an example, if the tons is rolled onto the lift, this can provide significant balanced out loading problems for the accuracy lift table. If the tons is decreased onto the lift, then there is much less of a chance for deflection and also damages to the lift.
The technique in how the accuracy lift will certainly be controlled has to be discussed early in your drawing board. A lot of automated lifts are regulated with a PLC as opposed to a human operator, However, if an operator is responsible for cycling the lift, then the unit will likely need to be outfitted with a vertical string encoder or limit switches. The upright 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 operate in similar manner, however with much less adaptability.
5. Responsibility Cycle:
Precision lift tables are frequently high task cycle lift tables as many automation does not involve the human operator. Therefore, the lifter needs to do its cycling at an accelerated price as its output is much higher than a typical lift. Responsibility cycling can be as high as 120 times an hr based on the application needs as well as the material that is being generated. If this is a sign of your application, after that this will need the precision lift table to be strengthened at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
