Take into consideration these 5 bottom lines before buying a accuracy lift table for your combination project.
Identify the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in elevation that is as good as +/ -.025″ of an inch. Keep in mind, the more precise the lift needs to be, the extra expensive it is going to cost you.
2. Permitted Lots Drift:
If your application needs absolutely no tons drift, after that you a accuracy ball screw lift table may be your best option. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which consequently raises as well as reduces the lift. They are extremely accurate as well as additionally have zero tons drift. This unit is terrific for applications that require to have security at any height and for prolonged periods of time.
3. Loading Conditions:
It will certainly be essential to recognize exactly how the tons is transferred onto and also off of the precision lift table. If your application calls for the lift to be loaded at a mid-stroke placement, (that is where the lift is not completely raised, or totally decreased) after that you need to be clear with the manufacturer on just how that tons is positioned onto the lift. For example, if the tons is rolled onto the lift, this might offer significant balanced out loading problems for the accuracy lift table. If the tons is decreased onto the lift, then there is less of a chance for deflection as well as damage to the lift.
The approach in how the precision lift will be managed has to be talked about early in your drawing board. The majority of automated lifts are regulated with a PLC instead of a human operator, However, if an driver is in charge of cycling the lift, then the system will likely need to be equipped with a upright string encoder or limit buttons. The vertical string encoder will maintain the PLC informed on what altitude the lift is currently at. This allows it to quit at predetermined elevations as needed by the application. The limit switches work in similar fashion, however with less flexibility.
5. Obligation Cycle:
Precision lift tables are typically high task cycle lift tables as a lot of automation does not include the human driver. Therefore, the lifter needs to execute its biking at an sped up price as its output is a lot more than a conventional lift. Task cycling can be as high as 120 times an hour based upon the application requirements and the material that is being generated. If this is indicative of your application, then this will certainly require the precision lift table to be strengthened at the scissor joints, the scissor tracks, as well as likewise the roller wheels.
