Consider these 5 key points prior to acquiring a precision lift table for your combination job.
Determine the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in altitude that is just as good as +/ -.025″ of an inch. Keep in mind, the more precise the lift needs to be, the much more pricey it is mosting likely to cost you.
2. Allowed Tons Drift:
If your application calls for absolutely no lots drift, after that you a accuracy ball screw lift table could be your finest alternative. These Electro-mechanical lifts are powered by an electric motor which transforms a screw which in turn increases and also decreases the lift. They are very precise and additionally have no load drift. This system is wonderful for applications that require to have security at any kind of height and for prolonged time periods.
3. Filling Conditions:
It will certainly be necessary to recognize how the tons is moved onto and off of the precision lift table. If your application calls for the lift to be filled at a mid-stroke setting, (that is where the lift is not fully raised, or totally reduced) then you require to be clear with the producer on exactly how that load is put onto the lift. For example, if the lots is rolled onto the lift, this could provide major offset loading troubles for the precision lift table. If the load is lowered onto the lift, after that there is much less of a chance for deflection as well as damage to the lift.
The technique in just how the precision lift will be managed needs to be discussed early in your drawing board. The majority of automated lifts are regulated with a PLC as opposed to a human operator, Nevertheless, if an driver is in charge of cycling the lift, then the unit will likely need to be equipped with a upright string encoder or limit switches. The vertical string encoder will certainly keep the PLC informed on what elevation the lift is currently at. This enables it to quit at predetermined heights as called for by the application. The limit switches work in similar fashion, but with less flexibility.
5. Duty Cycle:
Precision lift tables are commonly high responsibility cycle lift tables as the majority of automation does not entail the human driver. Thus, the lifter must perform its biking at an accelerated price as its output is much more than a traditional lift. Responsibility cycling can be as high as 120 times an hr based upon the application demands as well as the product that is being created. If this is indicative of your application, then this will call for the precision lift table to be enhanced at the scissor joints, the scissor tracks, as well as additionally the roller wheels.
