Consider these 5 bottom lines prior to buying a accuracy lift table for your integration project.
Determine the quantity 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. Keep in mind, the a lot more accurate the lift has to be, the extra costly it is mosting likely to cost you.
2. Allowed Load Drift:
If your application calls for no lots drift, after that you a accuracy sphere screw lift table may be your best alternative. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which in turn elevates and also lowers the lift. They are extremely accurate and additionally have absolutely no load drift. This system is great for applications that need to have stability at any type of elevation and also for prolonged time periods.
3. Filling Conditions:
It will certainly be important to know how the load is transferred 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 completely elevated, or completely reduced) after that you need to be clear with the maker on exactly how that load is positioned onto the lift. For example, if the lots is rolled onto the lift, this could offer major offset loading troubles for the precision lift table. If the load is lowered onto the lift, then there is less of a opportunity for deflection and damages to the lift.
The technique in just how the precision lift will certainly be managed has to be gone over early in your drawing board. Many automated lifts are managed with a PLC as opposed to a human operator, Nonetheless, if an operator is accountable for cycling the lift, then the unit will likely have to be geared up with a vertical string encoder or limitation buttons. The vertical string encoder will maintain the PLC informed on what altitude the lift is presently at. This enables it to quit at predetermined elevations as called for by the application. The limit changes operate in much the same manner, however with less adaptability.
5. Duty Cycle:
Precision lift tables are frequently high duty cycle lift tables as the majority of automation does not include the human operator. Thus, the lifter must execute its cycling at an increased rate as its outcome is much more than a standard lift. Obligation biking can be as high as 120 times an hour based on the application needs and the material that is being created. If this is indicative of your application, then this will need the accuracy lift table to be reinforced at the scissor joints, the scissor tracks, and also the roller wheels.
