Consider these 5 key points before purchasing a precision lift table for your combination job.
Determine the quantity 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. Remember, the a lot more accurate the lift needs to be, the a lot more pricey it is mosting likely to cost you.
2. Allowed Load Drift:
If your application calls for zero lots drift, then you a precision ball screw lift table may be your best alternative. These Electro-mechanical lifts are powered by an electrical motor which transforms a screw which subsequently elevates as well as reduces the lift. They are very specific as well as likewise have no load drift. This unit is terrific for applications that need to have security at any type of elevation and for long term time periods.
3. Filling Problems:
It will be very important to understand how the load is transferred onto and off of the precision lift table. If your application requires the lift to be filled at a mid-stroke position, (that is where the lift is not fully increased, or fully lowered) then you need to be clear with the maker on how that lots is positioned onto the lift. For example, if the load is rolled onto the lift, this could present major offset loading troubles for the accuracy lift table. If the lots is lowered onto the lift, after that there is much less of a possibility for deflection and damage to the lift.
The approach in exactly how the accuracy lift will be managed needs to be gone over early in your drawing board. Many automated lifts are regulated with a PLC rather than a human operator, Nonetheless, if an operator is accountable for cycling the lift, then the unit will likely need to be furnished with a upright string encoder or restriction switches. The upright string encoder will maintain the PLC informed on what altitude the lift is currently at. This allows it to quit at established elevations as needed by the application. The limit switches over operate in similar fashion, yet with much less flexibility.
5. Duty Cycle:
Precision lift tables are typically high task cycle lift tables as many automation does not involve the human operator. Hence, the lifter needs to execute its biking at an increased rate as its output is much greater than a typical lift. Task cycling can be as high as 120 times an hour based upon the application demands and the product that is being created. If this is a measure of your application, then this will certainly require the precision lift table to be strengthened at the scissor joints, the scissor tracks, and additionally the roller wheels.
