Take into consideration these 5 bottom lines before buying a accuracy lift table for your combination project.
Figure out 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. Keep in mind, the much more precise the lift needs to be, the more pricey it is going to cost you.
2. Allowed Lots Drift:
If your application calls for no load drift, then you a accuracy round screw lift table may be your ideal choice. These Electro-mechanical lifts are powered by an electric motor which turns a screw which subsequently elevates as well as reduces the lift. They are really exact as well as likewise have zero tons drift. This device is wonderful for applications that need to have stability at any height as well as for prolonged periods of time.
3. Filling Problems:
It will be necessary to understand just how the load is moved onto and off of the accuracy lift table. If your application calls for the lift to be filled at a mid-stroke setting, (that is where the lift is not completely raised, or completely lowered) after that you require to be clear with the supplier on how that load is positioned onto the lift. For instance, if the tons is rolled onto the lift, this might provide significant balanced out loading problems for the precision lift table. If the load is decreased onto the lift, after that there is less of a chance for deflection as well as damage to the lift.
The technique in exactly how the accuracy lift will certainly be controlled needs to be gone over early in your planning stages. The majority of automated lifts are controlled with a PLC rather than a human operator, However, if an operator is in charge of cycling the lift, after that the system will likely have to be equipped with a vertical string encoder or limit buttons. The vertical string encoder will certainly maintain the PLC informed on what elevation the lift is currently at. This permits it to quit at predetermined heights as called for by the application. The limit switches over operate in similar fashion, but with less flexibility.
5. Responsibility Cycle:
Precision lift tables are usually high responsibility cycle lift tables as many automation does not include the human driver. Therefore, the lifter should perform its cycling at an sped up rate as its result is much greater than a conventional lift. Duty cycling can be as high as 120 times an hour based on the application demands as well as the product that is being generated. If this is a sign of your application, then this will certainly require the precision lift table to be enhanced at the scissor joints, the scissor tracks, and additionally the roller wheels.
