Consider these 5 key points prior to buying a accuracy lift table for your combination task.
Figure out the quantity of deflection that serves for your application. Accuracy lift tables can have repeatability in elevation that is comparable to +/ -.025″ of an inch. Bear in mind, the more accurate the lift has to be, the a lot more expensive it is going to cost you.
2. Allowable Lots Drift:
If your application needs zero load drift, after that you a accuracy ball screw lift table might be your ideal choice. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which subsequently elevates as well as reduces the lift. They are really accurate and additionally have zero tons drift. This unit is excellent for applications that need to have security at any kind of height as well as for extended time periods.
3. Filling Problems:
It will be necessary to recognize how the load is transferred onto and off of the precision lift table. If your application needs the lift to be filled at a mid-stroke placement, (that is where the lift is not completely elevated, or totally reduced) after that you need to be clear with the producer on exactly how that load is positioned onto the lift. As an example, if the load is rolled onto the lift, this might provide significant countered loading troubles for the precision lift table. If the lots is decreased onto the lift, after that there is less of a opportunity for deflection and also damage to the lift.
The approach in how the precision lift will certainly be managed needs to be gone over early in your drawing board. The majority of automated lifts are controlled with a PLC instead of a human driver, However, if an driver is accountable for cycling the lift, then the system will likely need to be geared up with a upright string encoder or limitation switches. The vertical string encoder will keep the PLC informed on what altitude the lift is presently at. This allows it to stop at established heights as required by the application. The limit switches over operate in much the same way, however with much less flexibility.
5. Obligation Cycle:
Precision lift tables are usually high obligation cycle lift tables as the majority of automation does not entail the human operator. Thus, the lifter needs to perform its cycling at an increased price as its output is much higher than a typical lift. Obligation cycling can be as high as 120 times an hr based upon the application demands as well as the product that is being produced. If this is a sign of your application, then this will require the precision lift table to be reinforced at the scissor joints, the scissor tracks, and likewise the roller wheels.
