Consider these 5 key points prior to acquiring a precision lift table for your assimilation project.
Establish the amount of deflection that serves for your application. Precision lift tables can have repeatability in elevation that is just as good as +/ -.025″ of an inch. Bear in mind, the more precise the lift has to be, the much more pricey it is mosting likely to cost you.
2. Allowed Tons Drift:
If your application requires absolutely no tons drift, after that you a precision sphere screw lift table may be your best option. These Electro-mechanical lifts are powered by an electric motor which turns a screw which subsequently raises and also decreases the lift. They are very exact as well as additionally have zero lots drift. This system is fantastic for applications that require to have stability at any kind of height and for long term time periods.
3. Loading Problems:
It will be necessary to know just how the lots is moved onto and off of the precision lift table. If your application calls for the lift to be loaded at a mid-stroke placement, (that is where the lift is not totally elevated, or completely reduced) then you need to be clear with the supplier on just how that load is put onto the lift. For example, if the lots is rolled onto the lift, this might provide significant offset loading issues for the accuracy lift table. If the tons is lowered onto the lift, after that there is much less of a opportunity for deflection and damage to the lift.
The approach in just how the accuracy lift will certainly be regulated needs to be talked about early in your drawing board. Many automated lifts are managed with a PLC as opposed to a human operator, However, if an driver is responsible for cycling the lift, after that the unit will likely need to be geared up with a vertical string encoder or limitation switches. The vertical string encoder will maintain the PLC informed on what altitude the lift is presently at. This permits it to quit at fixed elevations as needed by the application. The limit switches over work in much the same way, yet with less flexibility.
5. Obligation Cycle:
Accuracy lift tables are usually high responsibility cycle lift tables as the majority of automation does not entail the human operator. Therefore, the lifter has to do its biking at an accelerated price as its output is much higher than a conventional lift. Task biking can be as high as 120 times an hour based on the application needs and the product that is being generated. If this is a measure of your application, after that this will certainly call for the precision lift table to be strengthened at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
