Take into consideration these 5 bottom lines prior to buying a precision lift table for your combination job.
Identify 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 much more precise the lift needs to be, the much more costly it is going to cost you.
2. Allowed Load Drift:
If your application requires absolutely no tons drift, after that you a accuracy round screw lift table could be your ideal option. These Electro-mechanical lifts are powered by an electrical motor which turns a screw which subsequently raises and decreases the lift. They are extremely precise and also have zero load drift. This device is terrific for applications that need to have security at any kind of height and for long term time periods.
3. Loading Conditions:
It will be very important to understand how the load is transferred onto and also off of the precision lift table. If your application needs the lift to be filled at a mid-stroke setting, (that is where the lift is not totally raised, or completely decreased) then you need to be clear with the producer on exactly how that load is placed onto the lift. For example, if the load is rolled onto the lift, this might present significant offset loading troubles for the accuracy lift table. If the load is lowered onto the lift, then there is much less of a possibility for deflection as well as damages to the lift.
The approach in just how the accuracy lift will certainly be regulated needs to be gone over early in your drawing board. Many automated lifts are controlled with a PLC instead of a human operator, However, if an driver is in charge of cycling the lift, then the unit will likely have to be outfitted with a upright string encoder or limitation switches. The upright string encoder will certainly maintain the PLC informed on what altitude the lift is currently at. This enables it to stop at established elevations as required by the application. The limit switches over work in similar fashion, but with much less flexibility.
5. Responsibility Cycle:
Precision lift tables are typically high task cycle lift tables as a lot of automation does not involve the human operator. Thus, the lifter should execute its cycling at an sped up rate as its output is a lot greater than a standard lift. Responsibility biking can be as high as 120 times an hour based on the application demands and also the material that is being generated. If this is indicative of your application, then this will need the accuracy lift table to be enhanced at the scissor joints, the scissor tracks, and likewise the roller wheels.
