Think about these 5 key points before buying a accuracy lift table for your combination project.
Establish the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in altitude that is as good as +/ -.025″ of an inch. Keep in mind, the more precise the lift has to be, the a lot more costly it is mosting likely to cost you.
2. Allowable Tons Drift:
If your application needs absolutely no lots drift, then you a precision ball screw lift table might be your finest choice. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which consequently elevates and also lowers the lift. They are very precise and additionally have absolutely no lots drift. This system is excellent for applications that need to have security at any type of elevation as well as for prolonged periods of time.
3. Packing Problems:
It will be essential to understand exactly how the tons is moved onto as well as off of the accuracy lift table. If your application requires the lift to be packed at a mid-stroke setting, (that is where the lift is not totally raised, or completely lowered) then you require to be clear with the supplier on exactly how that load is positioned onto the lift. For instance, if the load is rolled onto the lift, this might offer major balanced out loading problems for the accuracy lift table. If the tons is lowered onto the lift, after that there is less of a opportunity for deflection and also damages to the lift.
The approach in just how the accuracy lift will be managed needs to be gone over early in your drawing board. A lot of automated lifts are controlled with a PLC instead of a human operator, Nonetheless, if an operator is accountable for cycling the lift, then the unit will likely need to be equipped with a upright string encoder or limit buttons. The upright string encoder will certainly maintain the PLC informed on what elevation the lift is presently at. This permits it to quit at established elevations as needed by the application. The limit switches work in similar fashion, however with much less flexibility.
5. Responsibility Cycle:
Accuracy lift tables are typically high task cycle lift tables as many automation does not involve the human driver. Hence, the lifter must execute its biking at an increased rate as its output is much greater than a typical lift. Task biking can be as high as 120 times an hr based on the application demands and also the material that is being generated. If this is indicative of your application, then this will certainly need the precision lift table to be enhanced at the scissor joints, the scissor tracks, and additionally the roller wheels.
