Sorting Through The Maze Of Scissor Lift Tables
Most people have seen scissor lift tables, even if they don't know it. This is the lift platform that moves vertically and does so by using folding, linked supports that criss-cross one another in an "X" pattern. As pressure is applied to the lowest set of supports, this elongates the crossing pattern and propels the work platform up vertically. The force that causes the contraction of th scissoring action is either pneumatic, hydraulic or mechanical.
If your business or organization needs to either buy or rent scissor lift tables, there are a few things to keep in mind. Otherwise you risk losing a lot of money and not achieving the results you were wanting. To get the right one, ask yourself these questions:
* Who was the manufacturer? This matters now more than ever due to the large number of lift tables available.....some good, others not so good. Unfortunately some of these lifts made by companies you've never heard of are designed to be cheap rather than to be safe or efficient. This is not meant to foster stereotypes, but the best lifts are made in the United States, and that's what you should look for: American made. Presto is a perfect example: Top quality product made in the United States.
* What duty cycle is required? You'll probably need a high-duty cycle lift table if your application requires a table that cycles more than 20 times per hour. Most lifts are designed to only cycle two or three times per hour. They could become prematurely worn if they cycle more than that.
* Is the load centered? Scissor lift tables with a load that is offset are simply not safe and might prematurely wear out the joints and components. Avoid any load above 30% offset from the center of the lift.
* How will the operator be loading and unloading the table? It's best if you have the material to be moved around 30 to 42 inches off the ground. This should keep it about elbow-height to the operator. If you're lifting flat sheets, then a lift by itself can be used. However, if your material is in boxes, you should have both a lift and rotate. This rotate prevents the operator for the need to reach across the pallet. And finally, if your material is in a bin, then use a lift and tilt.
* Does your lifting require you to move your center of action frequently, from one place to another? (For instance, if you're painting a large room, you might need the lift to be in one place holding paint and rollers and then need it moved a few feet a little later and a few feet more still later, etc. If so, consider a mobile lift.
Whatever the answers to these questions, remember that safety is the primary consideration for buying your lift, whether a scissor or even a used wheelchair lift. This means that it needs to have proper safety features. This includes safety skirts to protect pinch points, as well as angled toe guards for preventing sheer points.
If you'll keep these suggestions in mind as you shop the world of scissor lift tables, you're much more likely to wind up with something that suits your needs, that is efficient and that is safe. Remember that as with so many other things, the key to success is to do your homework first.
