Take into consideration these 5 bottom lines prior to purchasing a precision lift table for your assimilation project.
Determine the quantity of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in altitude that is comparable to +/ -.025″ of an inch. Keep in mind, the extra precise the lift needs to be, the more costly it is mosting likely to cost you.
2. Allowable Lots Drift:
If your application requires no load drift, then you a precision round screw lift table may be your ideal alternative. These Electro-mechanical lifts are powered by an electric motor which turns a screw which consequently raises and lowers the lift. They are extremely specific as well as also have no tons drift. This unit is great for applications that require to have security at any kind of height and also for extended periods of time.
3. Packing Problems:
It will certainly be very important to know exactly how the load is transferred onto as well as off of the precision lift table. If your application needs the lift to be loaded at a mid-stroke position, (that is where the lift is not completely increased, or totally lowered) then you need to be clear with the producer on exactly how that load is positioned onto the lift. For example, if the lots is rolled onto the lift, this can offer major countered loading issues for the accuracy lift table. If the load is decreased onto the lift, then there is less of a chance for deflection and damages to the lift.
The technique in just how the accuracy lift will certainly be managed has to be talked about early in your planning stages. A lot of automated lifts are regulated with a PLC as opposed to a human driver, Nevertheless, if an operator is accountable for cycling the lift, then the system will likely have to be furnished with a vertical string encoder or limit switches. The vertical string encoder will certainly keep the PLC informed on what elevation the lift is presently at. This permits it to stop at predetermined elevations as called for by the application. The limit switches operate in much the same manner, but with much less adaptability.
5. Duty Cycle:
Accuracy lift tables are often high responsibility cycle lift tables as most automation does not involve the human driver. Therefore, the lifter must execute its biking at an sped up price as its output is much higher than a traditional lift. Responsibility biking can be as high as 120 times an hour based on the application needs and the product that is being created. If this is a measure of your application, after that this will certainly require the precision lift table to be strengthened at the scissor joints, the scissor tracks, and likewise the roller wheels.
