Take into consideration these 5 key points prior to purchasing a accuracy lift table for your integration task.
Identify the quantity of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in altitude that is like +/ -.025″ of an inch. Keep in mind, the more precise the lift needs to be, the much more expensive it is going to cost you.
2. Permitted Tons Drift:
If your application requires zero tons drift, after that you a accuracy sphere screw lift table might be your ideal option. These Electro-mechanical lifts are powered by an electrical motor which transforms a screw which subsequently raises and lowers the lift. They are extremely exact and likewise have no lots drift. This system is fantastic for applications that need to have security at any height and for long term time periods.
3. Loading Problems:
It will be important to know just how the lots is transferred onto as well as off of the accuracy lift table. If your application calls for the lift to be filled at a mid-stroke placement, (that is where the lift is not totally elevated, or totally reduced) after that you require to be clear with the manufacturer on exactly how that load is put onto the lift. As an example, if the lots is rolled onto the lift, this might provide significant offset loading troubles for the accuracy lift table. If the load is decreased onto the lift, then there is much less of a chance for deflection as well as damage to the lift.
The method in exactly how the precision lift will certainly be managed has to be gone over early in your drawing board. Many automated lifts are managed with a PLC instead of a human operator, Nevertheless, if an driver is accountable for cycling the lift, after that the device will likely have to be outfitted with a vertical string encoder or restriction buttons. The vertical string encoder will certainly keep the PLC informed on what elevation the lift is presently at. This permits it to quit at established heights as required by the application. The limit switches over operate in similar way, however with much less flexibility.
5. Obligation Cycle:
Accuracy lift tables are frequently high responsibility cycle lift tables as the majority of automation does not entail the human operator. Therefore, the lifter has to perform its biking at an increased rate as its output is a lot higher than a typical lift. Duty biking can be as high as 120 times an hour based upon the application demands and the product that is being generated. If this is indicative of your application, then this will certainly call for the precision lift table to be enhanced at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
