Skatewheel Conveyors These are used when the surface of the load is inconsistent - for example sacks instead of boxes. We also sell skatewheel product that expands as well. A minimum of 3 axles must be under your package at all times.
Roller Conveyors These gravity conveyors are used for unit loads. Our roller product runs from .75 inch (smallest in the industry) all the way to 3.5 in diameter rollers.
Roller Conveyors are sold in various roller centers. A Roller Center is the measure from the center of one roller to the center of the next. This is a very important figure as having to great a roller center allows boxes to submarine. A Flexible package requires 4 rollers under the package where a rigid package requires only 3. Divide the box length by 3 or 4, and the whole number portion is the required roller center - order that amount or a smaller roller center. Example 12 in rigid box - 12/3 = 4 - so order a roller conveyor with no greater than 4 inch roller center. For very small packages, our mini roller conveyors have a roller center as small as 1 inch ( for 3 inch long packages!!)
When we fill your conveyor order, we will ship rollers set high unless quoted otherwise. Rollers set high means that the top of the roller is exposed when looking at the cross section of the frame. For this reason, boxes will not hang up on rails ( unless they are too wide or flimsy). If you require set low ( with the frames working as a channel), please call us at 800-209-8798 or click on contact us for a special quotation.
Power Conveyors - When gravity is working against you, why not use electricity? Power units allow customers to move product in an efficient manner that could not be done with only gravity sections and people power. For power units, we have chain driven liver roller, line shaft, and stairway conveyors as well. We also sell accumulating in low back pressure and zero pressure.
In many cases it makes sense to order integral feeders with your conveyors so the boxes are consistently pushed onto the incline belt. Most inclined units also have double 'noseover' this device allows an inclined conveyor to transition from incline to horizontal in 2 small bumps rather than one thump - from incline to horizontal. We have the skill and desire to help you with your requirements - give us a try 800-209-8798.
