Take into consideration these 5 bottom lines prior to buying a accuracy lift table for your combination task.
Establish the quantity of deflection that serves for your application. Accuracy lift tables can have repeatability in altitude that is like +/ -.025″ of an inch. Bear in mind, the more exact the lift has to be, the more costly it is going to cost you.
2. Allowable Tons Drift:
If your application requires no load drift, after that you a precision ball screw lift table could be your ideal option. These Electro-mechanical lifts are powered by an electrical motor which transforms a screw which consequently raises and also lowers the lift. They are really specific and likewise have no tons drift. This system is wonderful for applications that require to have stability at any height and also for prolonged amount of times.
3. Packing Problems:
It will certainly be necessary to understand just how the lots is moved onto and off of the accuracy lift table. If your application calls for the lift to be filled at a mid-stroke position, (that is where the lift is not completely raised, or fully decreased) then you need to be clear with the manufacturer on how that load is positioned onto the lift. For example, if the tons is rolled onto the lift, this might provide major offset loading problems for the precision lift table. If the lots is lowered onto the lift, after that there is much less of a chance for deflection and also damage to the lift.
The method in exactly how the precision lift will be regulated has to be talked about early in your drawing board. A lot of automated lifts are regulated with a PLC rather than a human operator, However, if an driver is in charge of cycling the lift, after that the device will likely need to be geared up with a upright string encoder or limit switches. The upright string encoder will certainly maintain the PLC informed on what elevation the lift is currently at. This enables it to quit at established heights as called for by the application. The limit switches operate in similar way, yet with less flexibility.
5. Duty Cycle:
Accuracy lift tables are frequently high duty cycle lift tables as the majority of automation does not entail the human operator. Therefore, the lifter must do its cycling at an accelerated price as its output is a lot higher than a standard lift. Responsibility cycling can be as high as 120 times an hour based upon the application requirements as well as the product that is being created. If this is a sign of your application, then this will certainly call for the precision lift table to be reinforced at the scissor joints, the scissor tracks, as well as likewise the roller wheels.
