Consider these 5 bottom lines before acquiring a precision lift table for your combination task.
Establish the amount of deflection that serves for your application. Accuracy lift tables can have repeatability in altitude that is like +/ -.025″ of an inch. Remember, the more precise the lift has to be, the much more pricey it is mosting likely to cost you.
2. Allowable Load Drift:
If your application needs zero load drift, then you a precision ball screw lift table might be your finest alternative. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which consequently elevates and lowers the lift. They are very precise and likewise have no load drift. This device is fantastic for applications that need to have security at any height and for prolonged periods of time.
3. Loading Problems:
It will certainly be important to know how the tons is moved onto as well as off of the precision lift table. If your application needs the lift to be packed at a mid-stroke placement, (that is where the lift is not totally raised, or totally lowered) after that you need to be clear with the supplier on exactly how that load is positioned onto the lift. As an example, if the tons is rolled onto the lift, this can present significant balanced out loading problems for the precision lift table. If the lots is decreased onto the lift, then there is less of a possibility for deflection and damage to the lift.
The technique in just how the accuracy lift will certainly be regulated needs to be discussed early in your drawing board. Most automated lifts are regulated with a PLC as opposed to a human driver, Nonetheless, if an driver is responsible for cycling the lift, then the device will likely need to be equipped with a vertical string encoder or limit buttons. The vertical string encoder will certainly keep the PLC informed on what altitude the lift is currently at. This permits it to stop at fixed elevations as required by the application. The limit switches over operate in much the same manner, yet with less flexibility.
5. Task Cycle:
Precision lift tables are usually high responsibility cycle lift tables as most automation does not include the human driver. Thus, the lifter has to execute its cycling at an accelerated rate as its output is much higher than a conventional lift. Duty cycling can be as high as 120 times an hour based upon the application requirements and the product that is being generated. If this is a measure of your application, after that this will require the precision lift table to be enhanced at the scissor joints, the scissor tracks, and likewise the roller wheels.
