Think about these 5 bottom lines before buying a precision lift table for your combination job.
Determine the amount of deflection that is acceptable for your application. Precision lift tables can have repeatability in elevation that is comparable to +/ -.025″ of an inch. Remember, the much more accurate the lift needs to be, the more costly it is going to cost you.
2. Allowable Tons Drift:
If your application needs zero tons drift, after that you a accuracy sphere screw lift table could be your finest option. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which consequently raises and reduces the lift. They are extremely exact as well as also have no lots drift. This system is great for applications that require to have stability at any type of height and also for long term amount of times.
3. Packing Conditions:
It will be necessary to know how the load is transferred onto and off of the precision lift table. If your application requires the lift to be filled at a mid-stroke position, (that is where the lift is not completely raised, or completely lowered) then you require to be clear with the supplier on just how that lots is put onto the lift. For example, if the lots is rolled onto the lift, this could provide major balanced out loading issues for the accuracy lift table. If the tons is reduced onto the lift, after that there is less of a chance for deflection as well as damage to the lift.
The approach in how the precision lift will be controlled needs to be gone over early in your drawing board. Most automated lifts are controlled with a PLC instead of a human driver, Nevertheless, if an driver is in charge of cycling the lift, after that the unit will likely need to be outfitted with a vertical string encoder or limit switches. The vertical string encoder will maintain the PLC informed on what altitude the lift is presently at. This permits it to quit at fixed heights as needed by the application. The limit changes work in similar manner, but with much less versatility.
5. Duty Cycle:
Accuracy lift tables are often high duty cycle lift tables as the majority of automation does not include the human operator. Therefore, the lifter needs to perform its biking at an sped up price as its outcome is much higher than a conventional lift. Task biking can be as high as 120 times an hour based upon the application needs and the product that is being produced. If this is a sign of your application, after that this will call for the accuracy lift table to be enhanced at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
