Think about these 5 bottom lines prior to acquiring a accuracy lift table for your combination project.
Identify the amount of deflection that serves for your application. Accuracy lift tables can have repeatability in elevation that is just as good as +/ -.025″ of an inch. Bear in mind, the much more exact the lift needs to be, the much more costly it is mosting likely to cost you.
2. Allowed Tons Drift:
If your application requires absolutely no lots drift, after that you a precision sphere screw lift table may be your best choice. These Electro-mechanical lifts are powered by an electric motor which turns a screw which subsequently raises as well as lowers the lift. They are very exact as well as also have zero load drift. This unit is great for applications that require to have security at any kind of height and for long term periods of time.
3. Loading Conditions:
It will be important to understand how the load is transferred onto as well as off of the accuracy lift table. If your application needs the lift to be packed at a mid-stroke setting, (that is where the lift is not completely raised, or totally decreased) then you need to be clear with the maker on just how that lots is put onto the lift. For example, if the lots is rolled onto the lift, this might provide major countered loading issues for the accuracy lift table. If the tons is reduced onto the lift, after that there is less of a possibility for deflection and also damages to the lift.
The method in just how the precision lift will be controlled needs to be gone over early in your drawing board. Most automated lifts are controlled with a PLC rather than a human operator, However, if an driver is responsible for cycling the lift, after that the device will likely have to be geared up with a upright string encoder or limit switches. The upright string encoder will certainly keep the PLC informed on what altitude the lift is currently at. This allows it to quit at predetermined elevations as required by the application. The limit switches work in similar manner, but with less versatility.
5. Responsibility Cycle:
Precision lift tables are typically high responsibility cycle lift tables as many automation does not entail the human driver. Hence, the lifter has to do its biking at an accelerated rate as its output is much higher than a typical lift. Duty cycling can be as high as 120 times an hour based upon the application demands as well as the material that is being produced. If this is a sign of your application, after that this will need the accuracy lift table to be reinforced at the scissor joints, the scissor tracks, as well as also the roller wheels.
