Consider these 5 key points before acquiring a precision lift table for your combination project.
Figure out the quantity of deflection that is acceptable for your application. Precision lift tables can have repeatability in elevation that is just as good as +/ -.025″ of an inch. Remember, the a lot more accurate the lift needs to be, the much more pricey it is going to cost you.
2. Permitted Lots Drift:
If your application needs absolutely no load drift, after that you a precision round screw lift table may be your best option. These Electro-mechanical lifts are powered by an electric motor which turns a screw which subsequently elevates and also reduces the lift. They are really exact as well as additionally have zero load drift. This system is excellent for applications that need to have stability at any kind of height and also for extended periods of time.
3. Loading Problems:
It will certainly be very important to know how the load is transferred 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 fully increased, or fully decreased) then you need to be clear with the manufacturer on exactly how that load is positioned onto the lift. As an example, if the load is rolled onto the lift, this can present major balanced out loading problems for the precision lift table. If the load is decreased onto the lift, then there is much less of a possibility for deflection and also damages to the lift.
The technique in how the accuracy lift will certainly be managed has to be discussed early in your drawing board. Many automated lifts are regulated with a PLC as opposed to a human operator, However, if an operator is accountable for cycling the lift, after that the unit will likely have to be equipped with a upright string encoder or restriction buttons. The upright string encoder will keep the PLC informed on what altitude the lift is presently at. This permits it to quit at predetermined heights as called for by the application. The limit switches over work in much the same manner, but with much less flexibility.
5. Responsibility Cycle:
Precision lift tables are often high duty cycle lift tables as a lot of automation does not include the human driver. Therefore, the lifter should execute its biking at an increased price as its result is a lot more than a standard lift. Obligation cycling can be as high as 120 times an hour based on the application requirements and the product that is being generated. If this is a measure of your application, after that this will need the accuracy lift table to be strengthened at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
