Think about these 5 key points prior to buying a accuracy lift table for your integration job.
Figure out the amount of deflection that is acceptable for your application. Accuracy lift tables can have repeatability in elevation that is comparable to +/ -.025″ of an inch. Bear in mind, the extra exact the lift needs to be, the more expensive it is mosting likely to cost you.
2. Permitted Tons Drift:
If your application calls for absolutely no lots drift, after that you a accuracy round screw lift table could be your finest alternative. These Electro-mechanical lifts are powered by an electrical motor which turns a screw which in turn elevates and also decreases the lift. They are extremely accurate as well as also have zero load drift. This device is great for applications that need to have security at any kind of elevation and for extended periods of time.
3. Filling Problems:
It will certainly be necessary to know just how the tons is moved onto and also off of the accuracy lift table. If your application needs the lift to be filled at a mid-stroke placement, (that is where the lift is not completely increased, or fully reduced) after that you require to be clear with the manufacturer on exactly how that lots is placed onto the lift. As an example, if the load is rolled onto the lift, this could present major balanced out loading issues for the precision lift table. If the lots is reduced onto the lift, after that there is much less of a possibility for deflection and also damage to the lift.
The approach in exactly how the accuracy lift will certainly be managed has to be talked about early in your planning stages. Most automated lifts are managed with a PLC as opposed to a human driver, Nevertheless, if an driver is accountable for cycling the lift, after that the unit will likely have to be geared up with a vertical string encoder or limit switches. The upright string encoder will keep the PLC informed on what elevation the lift is currently at. This allows it to quit at predetermined heights as required by the application. The limit switches work in similar manner, however with less versatility.
5. Duty Cycle:
Precision lift tables are usually high responsibility cycle lift tables as most automation does not involve the human driver. Therefore, the lifter must execute its cycling at an accelerated price as its result is a lot greater than a traditional lift. Task cycling can be as high as 120 times an hr based on the application requirements as well as the material that is being generated. If this is a sign of your application, then this will certainly call for the precision lift table to be strengthened at the scissor joints, the scissor tracks, and also the roller wheels.
