Think about these 5 key points before purchasing a precision lift table for your integration job.
Identify the amount of deflection that is acceptable for your application. Precision lift tables can have repeatability in altitude that is like +/ -.025″ of an inch. Bear in mind, the a lot more accurate the lift needs to be, the a lot more costly it is going to cost you.
2. Allowable Tons Drift:
If your application needs absolutely no load drift, then you a accuracy sphere screw lift table could be your ideal choice. These Electro-mechanical lifts are powered by an electrical motor which transforms a screw which consequently increases and also lowers the lift. They are really precise and likewise have no load drift. This device is wonderful for applications that need to have stability at any type of elevation and also for prolonged periods of time.
3. Filling Conditions:
It will certainly be very important to know exactly how the tons is transferred onto and also off of the precision lift table. If your application calls for the lift to be packed at a mid-stroke placement, (that is where the lift is not fully elevated, or totally reduced) then you require to be clear with the manufacturer on exactly how that lots is put onto the lift. For instance, if the tons is rolled onto the lift, this might provide major countered loading issues for the precision lift table. If the load is lowered onto the lift, after that there is less of a opportunity for deflection as well as damage to the lift.
The technique in exactly how the precision lift will certainly be regulated has to be gone over early in your drawing board. The majority of automated lifts are controlled with a PLC instead of a human operator, However, if an operator is responsible for cycling the lift, then the device will likely need to be furnished with a vertical string encoder or limitation switches. The upright string encoder will maintain the PLC informed on what altitude the lift is currently at. This permits it to quit at predetermined elevations as required by the application. The limit switches over work in similar manner, yet with less adaptability.
5. Duty Cycle:
Precision lift tables are often high obligation cycle lift tables as most automation does not involve the human driver. Thus, the lifter should execute its biking at an accelerated rate as its result is much higher than a typical lift. Obligation cycling can be as high as 120 times an hour based upon the application requirements as well as the product that is being produced. If this is indicative of your application, then this will certainly need the precision lift table to be strengthened at the scissor joints, the scissor tracks, as well as likewise the roller wheels.
