Take into consideration these 5 key points before acquiring a precision lift table for your assimilation task.
Determine the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in elevation that is comparable to +/ -.025″ of an inch. Bear in mind, the a lot more specific the lift has to be, the more pricey it is going to cost you.
2. Allowable Lots Drift:
If your application needs zero lots drift, after that you a precision ball screw lift table might be your ideal option. These Electro-mechanical lifts are powered by an electric motor which turns a screw which consequently increases and decreases the lift. They are very exact as well as additionally have no load drift. This unit is great for applications that require to have stability at any type of elevation and for long term time periods.
3. Loading Conditions:
It will certainly be necessary to understand just how the lots is moved onto and off of the accuracy lift table. If your application calls for the lift to be filled at a mid-stroke position, (that is where the lift is not completely elevated, or fully decreased) then you need to be clear with the producer on exactly how that lots is placed onto the lift. As an example, if the lots is rolled onto the lift, this can present significant offset loading troubles for the precision lift table. If the lots is decreased onto the lift, after that there is much less of a chance for deflection and also damages to the lift.
The method in just how the accuracy lift will certainly be regulated needs to be reviewed early in your drawing board. The majority of automated lifts are regulated with a PLC rather than a human operator, However, if an driver is in charge of cycling the lift, then the device will likely have to be geared up with a vertical string encoder or limit buttons. The vertical string encoder will certainly maintain the PLC informed on what elevation the lift is presently at. This enables it to quit at established elevations as needed by the application. The limit changes work in much the same way, yet with much less adaptability.
5. Responsibility Cycle:
Accuracy lift tables are frequently high obligation cycle lift tables as a lot of automation does not entail the human operator. Therefore, the lifter should execute its biking at an accelerated rate as its result is a lot higher than a conventional lift. Task cycling can be as high as 120 times an hr based upon the application needs and also the product that is being produced. If this is a measure of your application, then this will require the precision lift table to be reinforced at the scissor joints, the scissor tracks, as well as likewise the roller wheels.
