Take into consideration these 5 key points prior to purchasing a accuracy lift table for your combination task.
Establish the quantity of deflection that serves for your application. Precision lift tables can have repeatability in elevation that is comparable to +/ -.025″ of an inch. Remember, the much more exact the lift needs to be, the extra costly it is mosting likely to cost you.
2. Permitted Tons Drift:
If your application needs absolutely no tons drift, then you a accuracy round screw lift table could be your finest choice. These Electro-mechanical lifts are powered by an electric motor which turns a screw which in turn increases and also reduces the lift. They are very exact as well as also have absolutely no lots drift. This system is fantastic for applications that need to have stability at any kind of elevation and also for long term amount of times.
3. Loading Problems:
It will be very important to recognize exactly how the tons is transferred onto and also off of the precision lift table. If your application requires the lift to be packed at a mid-stroke placement, (that is where the lift is not totally elevated, or totally lowered) after that you require to be clear with the supplier on just how that tons is positioned onto the lift. As an example, if the tons is rolled onto the lift, this can offer significant offset loading troubles for the precision lift table. If the lots is decreased onto the lift, after that there is less of a chance for deflection as well as damage to the lift.
The technique in just how the accuracy lift will certainly be managed needs to be talked about early in your planning stages. Many automated lifts are regulated with a PLC as opposed to a human driver, However, if an driver is in charge of cycling the lift, after that the device will likely need to be furnished with a vertical string encoder or restriction switches. The upright string encoder will maintain the PLC informed on what elevation the lift is presently at. This permits it to quit at predetermined heights as needed by the application. The limit switches operate in much the same way, but with much less versatility.
5. Duty Cycle:
Precision lift tables are often high duty cycle lift tables as the majority of automation does not include the human driver. Thus, the lifter has to perform its cycling at an increased rate as its result is a lot greater than a standard lift. Responsibility cycling can be as high as 120 times an hour based on the application requirements and the material that is being generated. If this is a measure of your application, then this will need the accuracy lift table to be strengthened at the scissor joints, the scissor tracks, as well as also the roller wheels.
